Theories of brain plasticity propose that, in the absence of input from the preferred sensory modality, some specialized brain areas may be recruited when processing information from other modalities, which may result in improved performance. The Useful Field of View task has previously been used to demonstrate that early deafness positively impacts peripheral visual attention. The current study sought to determine the neural changes associated with those deafness-related enhancements in visual performance. Based on previous findings, we hypothesized that recruitment of posterior portions of Brodmann area 22, a brain region most commonly associated with auditory processing, would be correlated with peripheral selective attention as measured using the Useful Field of View task. We report data from severe to profoundly deaf adults and normal-hearing controls who performed the Useful Field of View task while cortical activity was recorded using the event-related optical signal. Behavioral performance, obtained in a separate session, showed that deaf subjects had lower thresholds (i.e., better performance) on the Useful Field of View task. The event-related optical data indicated greater activity for the deaf adults than for the normal-hearing controls during the task in the posterior portion of Brodmann area 22 in the right hemisphere. Furthermore, the behavioral thresholds correlated significantly with this neural activity. This work provides further support for the hypothesis that cross-modal plasticity in deaf individuals appears in higher-order auditory cortices, whereas no similar evidence was obtained for primary auditory areas. It is also the only neuroimaging study to date that has linked deaf-related changes in the right temporal lobe to visual task performance outside of the imaging environment. The event-related optical signal is a valuable technique for studying cross-modal plasticity in deaf humans. The non-invasive and relatively quiet characteristics of

Appelman, Karen I; Callahan, Judy Ottren; Mayer, Margaret H; Luetke, Barbara S; Stryker, Deborah S

2012-01-01

Little information is available on the education, employment, and independent living status of young deaf and hard of hearing adults who have transitioned from high school. The present article reports postsecondary outcomes of 46 young adults who had attended for at least 4 years a non-public agency school in the northwestern United States specializing in deaf education. School administrators had developed a specific philosophy and operationalized it in an academic and literacy-based curriculum incorporating a grammatically accurate signing system. The researchers found that most or all participants had finished high school, had earned a college degree, were employed, and were living independently. Findings are discussed in terms of the available literature and the study's contribution to a limited body of recent research on young postsecondary deaf and hard of hearing adults.

2014-01-01

Using a prospective, longitudinal study design, this paper addresses the impact of genetic counseling and testing for deafness on deaf adults and the Deaf community. This study specifically evaluated the effect of genetic counseling and Connexin-26 and Connexin-30 genetic test results on participants' deaf identity and understanding of their genetic test results. Connexin-26 and Connexin-30 genetic testing was offered to participants in the context of linguistically and culturally appropriate genetic counseling. Questionnaire data collected from 209 deaf adults at four time points (baseline, immediately following pre-test genetic counseling, 1-month following genetic test result disclosure, and 6-months after result disclosure) were analyzed. Four deaf identity orientations (hearing, marginal, immersion, bicultural) were evaluated using subscales of the Deaf Identity Development Scale-Revised. We found evidence that participants understood their specific genetic test results following genetic counseling, but found no evidence of change in deaf identity based on genetic counseling or their genetic test results. This study demonstrated that culturally and linguistically appropriate genetic counseling can improve deaf clients' understanding of genetic test results, and the formation of deaf identity was not directly related to genetic counseling or Connexin-26 and Connexin-30 genetic test results.

Leveling the Playing Field? Communication Technology as a Predictor of Future Attainments for Deaf Young Adults

Carrie Lou Garberoglio

2015-11-01

Full Text Available Communication technologies are often proposed to level the playing field for individuals with disabilities, but the benefits may be magnified for deaf individuals in particular due to the communication barriers experienced by these individuals. In this paper, we set out to test the assumption that increased engagement with communication technology, specifically computer-mediated communication, during adolescence would contribute to actual attainment gains in adult life for deaf individuals in three domains: life, education, and employment. A secondary analysis using the National Longitudinal Transition Study 2 (NLTS2 was conducted, allowing for a longitudinal examination of deaf individuals' experiences in the transition from adolescence to adulthood. Findings revealed that deaf individuals who engaged with computer-mediated communication at higher frequencies during adolescence did not reveal discernible gains in adult life attainments in any domain. We propose that the benefits of communication technology only go so far, and that achieving greater equitable outcomes for deaf individuals requires larger systemic change.

Using American sign language interpreters to facilitate research among deaf adults: lessons learned.

Sheppard, Kate

2011-04-01

Health care providers commonly discuss depressive symptoms with clients, enabling earlier intervention. Such discussions rarely occur between providers and Deaf clients. Most culturally Deaf adults experience early-onset hearing loss, self-identify as part of a unique culture, and communicate in the visual language of American Sign Language (ASL). Communication barriers abound, and depression screening instruments may be unreliable. To train and use ASL interpreters for a qualitative study describing depressive symptoms among Deaf adults. Training included research versus community interpreting. During data collection, interpreters translated to and from voiced English and ASL. Training eliminated potential problems during data collection. Unexpected issues included participants asking for "my interpreter" and worrying about confidentiality or friendship in a small community. Lessons learned included the value of careful training of interpreters prior to initiating data collection, including resolution of possible role conflicts and ensuring conceptual equivalence in real-time interpreting.

Visual field bias in hearing and deaf adults during judgments of facial expression and identity.

Directory of Open Access Journals (Sweden)

Susan M Letourneau

2013-06-01

Full Text Available The dominance of the right hemisphere during face perception is associated with more accurate judgments of faces presented in the left rather than the right visual field. Previous research suggests that the left visual field bias typically observed during face perception tasks is reduced in deaf adults who use sign language, for whom facial expressions convey important linguistic information. The current study examined whether visual field biases were altered in deaf adults whenever they viewed expressive faces, or only when attention was explicitly directed to expression. Twelve hearing adults and 12 deaf signers were trained to recognize a set of novel faces posing various emotional expressions. They then judged the familiarity or emotion of faces presented in the left or right visual field, or both visual fields simultaneously. The same familiar and unfamiliar faces posing neutral and happy expressions were presented in the two tasks. Both groups were most accurate when faces were presented in both visual fields. Across tasks, the hearing group demonstrated a bias toward the left visual field. In contrast, the deaf group showed a bias toward the left visual field during identity judgments that shifted marginally toward the right visual field during emotion judgments. Two secondary conditions tested whether these effects generalized to angry faces and famous faces and similar effects were observed. These results suggest that attention to facial expression, not merely the presence of emotional expression, reduces a typical left visual field bias for face processing in deaf signers.

Case studies of adult d/Deaf or Hard of Hearing Multilingual Learners (DMLs) are few, especially studies of DMLs who learn more than one sign language and read logographic and alphabetic scripts. To reduce this paucity, two descriptive case studies are presented. Written questionnaires, face-to-face interviews, and self-appraisals of language-use rubrics were used to explore (a) the language and literacy histories of two adult Asian DMLs who had learned multiple languages: Chinese (spoken/written), English (written), Chinese Sign Language, and American Sign Language; and (b) how each language was used in different cultural communities with diverse conversational partners. Home literacy environment, family support, visual access to languages, peer and sibling support, role models, encouragement, perseverance, and Deaf identity all played vital roles in the participants' academic success. The findings provide insights into the acquisition of multiple languages and bi-literacy through social communication and academic content.

2015-07-01

Deaf and hard-of-hearing persons are at risk for experiencing traumatic events and such experiences are associated with symptoms of mental disorder. We investigated the prevalence of traumatic events and subsequent traumatization in adults referred to specialized psychiatric outpatient units for deaf and hard-of-hearing patients. Sixty-two patients were diagnosed with mental disorders and assessed for potential traumatic experiences in their preferred language and mode of communication using instruments translated into Norwegian Sign Language. All patients reported traumatic events, with a mean of 6.2 different types; 85% reported subsequent traumatization not significantly associated with either residential school setting or communicative competence of childhood caregivers. Traumatization patterns in both sexes were similar to those in hearing clinical samples. Findings indicate that psychiatric intake interviews should routinely assess potentially traumatic events and their impacts, and that mental health professionals working with deaf and hard-of-hearing patients should be able to treat trauma-related disorders. © The Author 2015.

Joining the diaspora of deaf memoirists: a personal account of writing deafness.

Science.gov (United States)

McDONALD, Donna

2014-01-01

In this essay, the author describes how, and why, she tackled a lifetime of questions about her deafness and experiences of being deaf by writing a memoir called The Art of Being Deaf. While researching her memoir, the author discovered that the questions about her deafness that she most needed to answer were her own. Having first read many memoirs by other deaf writers and novels with deaf characters, the author set about composing her own narrative of deafness in a fresh way. She not only came to an improved understanding of her deaf self, but grew into a more authentic understanding of her whole self, reconciling her memories of the deaf girl she once was with the adult deaf woman she is now. The author illustrates how the act of writing a memoir can be an important tool in resolving questions of identity.

"We communicated that way for a reason": language practices and language ideologies among hearing adults whose parents are deaf.

Science.gov (United States)

Pizer, Ginger; Walters, Keith; Meier, Richard P

2013-01-01

Families with deaf parents and hearing children are often bilingual and bimodal, with both a spoken language and a signed one in regular use among family members. When interviewed, 13 American hearing adults with deaf parents reported widely varying language practices, sign language abilities, and social affiliations with Deaf and Hearing communities. Despite this variation, the interviewees' moral judgments of their own and others' communicative behavior suggest that these adults share a language ideology concerning the obligation of all family members to expend effort to overcome potential communication barriers. To our knowledge, such a language ideology is not similarly pervasive among spoken-language bilingual families, raising the question of whether there is something unique about family bimodal bilingualism that imposes different rights and responsibilities on family members than spoken-language family bilingualism does. This ideology unites an otherwise diverse group of interviewees, where each one preemptively denied being a "typical CODA [children of deaf adult]."

Relationships in the Coda (Child of deaf adult family [Relacje w rodzinie CODA

2017-11-01

Full Text Available Human existence is accompanied by attempts at self understanding, finding one’s place in the world and a way to co-exist with other people. The very unique social and family situation of the hearing children of deaf parents allows the trials of clarification of what characterizes and distingishes them as Codas. The childhood, adolescence and adult life of Codas is definitely different than the lives of people living in hearing families. In the family in which one or both parents are deaf it is very likely that the way they are functioning will have consequences for their hearing childrens' future functioning. There are aspects of family life that have influence on this disguised difference, such as: forms of communication, pantomimic gestures, mimics and also the characteristic phenomena of family roles reversal. The relations in Codas untypical families are determined by multiple factors. Among them mutual understanding which, with the help of values presented and applied in the process of upbringing, is one of the most important as it may result, in the right circumstances, in achieving a unique family union. The forming of emotional bonds between deaf parents and their children is influenced by, for example fulfilling the need of love in the family house and the adequate use of situations which favour communication. Usually the perspective of time makes adult Codas more tolerant and fully understanding of the obligations assigned to them by deaf parents during their childhood and adolescence. Being a Coda each time is related to individual life situations in which some Codas may find themselves happy and fulfilled while others won’t .

Young Skilled Deaf Readers Have an Enhanced Perceptual Span in Reading.

Science.gov (United States)

Bélanger, Nathalie N; Lee, Michelle; Schotter, Elizabeth R

2017-04-27

Recently, Bélanger, Slattery, Mayberry and Rayner (2012) showed, using the moving window paradigm, that profoundly deaf adults have a wider perceptual span during reading relative to hearing adults matched on reading level. This difference might be related to the fact that deaf adults allocate more visual attention to simple stimuli in the parafovea (Bavelier, Dye & Hauser, 2006). Importantly, this reorganization of visual attention in deaf individuals is already manifesting in deaf children (Dye, Hauser & Bavelier, 2009). This leads to questions about the time course of the emergence of an enhanced perceptual span (which is under attentional control; Rayner, 2014; Miellet, O'Donnell, & Sereno, 2009) in young deaf readers. The present research addressed this question by comparing the perceptual spans of young deaf readers (age 7-15) and young hearing children (age 7-15). Young deaf readers, like deaf adults, were found to have a wider perceptual span relative to their hearing peers matched on reading level, suggesting that strong and early reorganization of visual attention in deaf individuals goes beyond the processing of simple visual stimuli and emerges into more cognitively complex tasks, such as reading.

In recent years, cochlear implants (CIs) have been provided in growing numbers to people with not only bilateral deafness but also to people with unilateral hearing loss, at times in order to alleviate tinnitus. This study presents audiological data from 15 adult participants (ages 48 ± 12 years) with single sided deafness. Results are presented from 9/15 adults, who received a CI (SSD-CI) in the deaf ear and were tested in Acoustic or Acoustic + CI hearing modes, and 6/15 adults who are planning to receive a CI, and were tested in the unilateral condition only. Testing included (1) audiometric measures of threshold, (2) speech understanding for CNC words and AzBIO sentences, (3) tinnitus handicap inventory, (4) sound localization with stationary sound sources, and (5) perceived auditory motion. Results showed that when listening to sentences in quiet, performance was excellent in the Acoustic and Acoustic + CI conditions. In noise, performance was similar between Acoustic and Acoustic + CI conditions in 4/6 participants tested, and slightly worse in the Acoustic + CI in 2/6 participants. In some cases, the CI provided reduced tinnitus handicap scores. When testing sound localization ability, the Acoustic + CI condition resulted in improved sound localization RMS error of 29.2° (SD: ±6.7°) compared to 56.6° (SD: ±16.5°) in the Acoustic-only condition. Preliminary results suggest that the perception of motion direction, whereby subjects are required to process and compare directional cues across multiple locations, is impaired when compared with that of normal hearing subjects.

Enhanced activation of the left inferior frontal gyrus in deaf and dyslexic adults during rhyming.

Science.gov (United States)

MacSweeney, Mairéad; Brammer, Michael J; Waters, Dafydd; Goswami, Usha

2009-07-01

Hearing developmental dyslexics and profoundly deaf individuals both have difficulties processing the internal structure of words (phonological processing) and learning to read. In hearing non-impaired readers, the development of phonological representations depends on audition. In hearing dyslexics, many argue, auditory processes may be impaired. In congenitally profoundly deaf individuals, auditory speech processing is essentially absent. Two separate literatures have previously reported enhanced activation in the left inferior frontal gyrus in both deaf and dyslexic adults when contrasted with hearing non-dyslexics during reading or phonological tasks. Here, we used a rhyme judgement task to compare adults from these two special populations to a hearing non-dyslexic control group. All groups were matched on non-verbal intelligence quotient, reading age and rhyme performance. Picture stimuli were used since this requires participants to generate their own phonological representations, rather than have them partially provided via text. By testing well-matched groups of participants on the same task, we aimed to establish whether previous literatures reporting differences between individuals with and without phonological processing difficulties have identified the same regions of differential activation in these two distinct populations. The data indicate greater activation in the deaf and dyslexic groups than in the hearing non-dyslexic group across a large portion of the left inferior frontal gyrus. This includes the pars triangularis, extending superiorly into the middle frontal gyrus and posteriorly to include the pars opercularis, and the junction with the ventral precentral gyrus. Within the left inferior frontal gyrus, there was variability between the two groups with phonological processing difficulties. The superior posterior tip of the left pars opercularis, extending into the precentral gyrus, was activated to a greater extent by deaf than dyslexic

Predicate Structures, Gesture, and Simultaneity in the Representation of Action in British Sign Language: Evidence From Deaf Children and Adults

Science.gov (United States)

Cormier, Kearsy

2013-01-01

British Sign Language (BSL) signers use a variety of structures, such as constructed action (CA), depicting constructions (DCs), or lexical verbs, to represent action and other verbal meanings. This study examines the use of these verbal predicate structures and their gestural counterparts, both separately and simultaneously, in narratives by deaf children with various levels of exposure to BSL (ages 5;1 to 7;5) and deaf adult native BSL signers. Results reveal that all groups used the same types of predicative structures, including children with minimal BSL exposure. However, adults used CA, DCs, and/or lexical signs simultaneously more frequently than children. These results suggest that simultaneous use of CA with lexical and depicting predicates is more complex than the use of these predicate structures alone and thus may take deaf children more time to master.

Children who are d/Deaf and hard of hearing (DHH) grow up in environments influenced by their parents' attitudes, which may facilitate or impede these children's development and participation (World Health Organization, 2007). The attitudes of 152 Australian parents of DHH children ages 3 years 7 months to 9 years 5 months (M = 6 years 5 months) were investigated with the Opinions About Deaf People Scale (Berkay, Gardner, & Smith, 1995a). The parents' responses showed very positive attitudes toward the capabilities of DHH adults, particularly on items describing their intellectual and vocational capabilities. Parents' responses to most of the items on the scale were positively skewed, raising questions about its validity as a research tool when used with parents of DHH children. The study findings suggest that for these children, parents' attitudes may facilitate rather than present an environmental barrier to their development.

Rehabilitation of deaf persons with cochlear implants

1997-01-01

In the last decade, the rehabilitation of postlingually deaf adults and prelingually deaf children with cochlear implants has been established as a treatment of deafness. The technological development of the implant devices and improvement of the surgical technique have led to a considerable increase of hearing performance during the last years. The postlingually deaf adults are able to use the telephone and may be integrated in their original job. Prelingually deaf children can even visit normal schools after cochlear implantation and hearing rehabilitation training. In order to preoperatively establish the state of the cochlear, radiological diagnosis of the temporal bone is necessary. High resolution computerized tomography imaging of the temporal bone with coronar and axial 1 mm slices and MRI with thin slice technique (three dimensional, T2 weighted turbo-spinecho sequence with 0.7 mm slices) have proved to be valuable according to our experience. Furthermore a postoperative synoptical X-ray, in a modified Chausse III projection, offers good information about the position of the implant and insertion of the stimulating electrode into the cochlea.

Penetrating brain injuries (PBI) are a medical emergency, often resulting in complex damage and high mortality rates. Neuroimaging is essential to evaluate the location and extent of injuries, and to manage them accordingly. Currently, a myriad of imaging modalities are included in the diagnostic workup for adult PBI, including skull radiography, computed tomography (CT), magnetic resonance imaging (MRI) and angiography, with each modality providing their own particular benefits. This literature review explores the current modalities available for investigating PBI and aims to assist in decision making for the appropriate use of diagnostic imaging when presented with an adult PBI. Based on the current literature, the authors have developed an imaging pathway for adult penetrating brain injury that functions as both a learning tool and reference guide for radiographers and other health professionals. Currently, CT is recommended as the imaging modality of choice for the initial assessment of PBI patients, while MRI is important in the sub-acute setting where it aids prognosis prediction and rehabilitation planning, Additional follow-up imaging, such as angiography, should be dependent upon clinical findings

2014-08-01

Full Text Available This paper discusses the communicative competence of deaf children. It illustrates the process in which such children build narrative texts in interaction with a deaf teacher, and presents the diversity of this process due to the shared vs. non-shared perception of a picture - the source of the topic. Detailed analyses focus on the formal and semantic aspect of the stories, including the length of the text in sign language, the content selected, information categories, and types of answers to the teacher’s questions. This text is our contribution in memory of Professor Grace Wales Shugar, whose idea of dual agentivity of child-adult interaction inspired the research presented here.

The Neural Basis of Speech Perception through Lipreading and Manual Cues: Evidence from Deaf Native Users of Cued Speech

Science.gov (United States)

Aparicio, Mario; Peigneux, Philippe; Charlier, Brigitte; Balériaux, Danielle; Kavec, Martin; Leybaert, Jacqueline

2017-01-01

We present here the first neuroimaging data for perception of Cued Speech (CS) by deaf adults who are native users of CS. CS is a visual mode of communicating a spoken language through a set of manual cues which accompany lipreading and disambiguate it. With CS, sublexical units of the oral language are conveyed clearly and completely through the visual modality without requiring hearing. The comparison of neural processing of CS in deaf individuals with processing of audiovisual (AV) speech in normally hearing individuals represents a unique opportunity to explore the similarities and differences in neural processing of an oral language delivered in a visuo-manual vs. an AV modality. The study included deaf adult participants who were early CS users and native hearing users of French who process speech audiovisually. Words were presented in an event-related fMRI design. Three conditions were presented to each group of participants. The deaf participants saw CS words (manual + lipread), words presented as manual cues alone, and words presented to be lipread without manual cues. The hearing group saw AV spoken words, audio-alone and lipread-alone. Three findings are highlighted. First, the middle and superior temporal gyrus (excluding Heschl’s gyrus) and left inferior frontal gyrus pars triangularis constituted a common, amodal neural basis for AV and CS perception. Second, integration was inferred in posterior parts of superior temporal sulcus for audio and lipread information in AV speech, but in the occipito-temporal junction, including MT/V5, for the manual cues and lipreading in CS. Third, the perception of manual cues showed a much greater overlap with the regions activated by CS (manual + lipreading) than lipreading alone did. This supports the notion that manual cues play a larger role than lipreading for CS processing. The present study contributes to a better understanding of the role of manual cues as support of visual speech perception in the framework

Language and cognitive development in deaf children: deaf children with deaf and deaf children with hearing parents

The article reviews the current studies regarding language and cognitive development in children who are deaf. Deaf communicate orally and with sign language. 90 % of deaf children are born into hearing families and hearing parents in most cases do not know the sign language. Besides, hearing parents usually want for their child to become "normally" speaking. Most of the deaf children born into hearing families have very poor early communication. It is now well established that deaf children ...

Do Older Adults Need Sleep? A Review of Neuroimaging, Sleep, and Aging Studies.

Science.gov (United States)

Scullin, Michael K

2017-09-01

Sleep habits, sleep physiology, and sleep disorders change with increasing age. However, there is a longstanding debate regarding whether older adults need sleep to maintain health and daily functioning (reduced-sleep-need view). An alternative possibility is that all older adults need sleep, but that many older adults have lost the ability to obtain restorative sleep (reduced-sleep-ability view). Prior research using behavioral and polysomnography outcomes has not definitively disentangled the reduced-sleep-need and reduced-sleep-ability views. Therefore, this review examines the neuroimaging literature to determine whether age-related changes in sleep cause-or are caused by-age-related changes in brain structure, function, and pathology. In middle-aged and older adults, poorer sleep quality, greater nighttime hypoxia, and shorter sleep duration related to cortical thinning in frontal regions implicated in slow wave generation, in frontoparietal networks implicated in cognitive control, and in hippocampal regions implicated in memory consolidation. Furthermore, poor sleep quality was associated with higher amyloid burden and decreased connectivity in the default mode network, a network that is disrupted in the pathway to Alzheimer's disease. All adults need sleep, but cortical thinning and amyloidal deposition with advancing age may weaken the brain's ability to produce restorative sleep. Therefore, sleep in older adults may not always support identical functions for physical, mental, and cognitive health as in young adults.

Testicular cancer typically affects young and middle-aged men. An educational video about prostate and testicular cancer was created in American Sign Language, with English open captioning and voice overlay, so that it could be viewed by audiences of diverse ages and hearing characteristics. This study recruited young Deaf (n = 85) and hearing (n = 90) adult males to help evaluate the educational value of the testicular cancer portion of this video. Participants completed surveys about their general, testicular, and total cancer knowledge before and after viewing the video. Although hearing men had higher pre-test scores than Deaf men, both Deaf and hearing men demonstrated significant increases in General, Testicular, and Total Cancer Knowledge scores after viewing the intervention video. Overall, results demonstrate the value of the video to Deaf and hearing men.

Worldwide, the population is aging and the number of individuals diagnosed with dementia is rising rapidly. Currently, there are no effective pharmaceutical cures. Hence, identifying lifestyle approaches that may prevent, delay, or treat cognitive impairment and dementia in older adults is becoming increasingly important. Computerized Cognitive Training (CCT) is a promising strategy to combat cognitive decline. Yet, the underlying mechanisms of the effect of CCT on cognition remain poorly understood. Hence, the primary objective of this systematic review was to examine peer-reviewed literature ascertaining the effect of CCT on both structural and functional neuroimaging measures among older adults to gain insight into the underlying mechanisms by which CCT may benefit cognitive function. In accordance with PRISMA guidelines, we used the following databases: MEDLINE, EMBASE, and CINAHL. Two independent reviewers abstracted data using pre-defined terms. These included: main study characteristics such as the type of training (i.e., single- versus multi-domain), participant demographics (age ≥ 50 years; no psychiatric conditions), and the inclusion of neuroimaging outcomes. The Physiotherapy Evidence Database (PEDro) scale was used to assess quality of all studies included in this systematic review. Nine studies were included in this systematic review, with four studies including multiple MRI sequences. Results of this systematic review are mixed: CCT was found to increase and decrease both brain structure and function in older adults. In addition, depending on region of interest, both increases and decreases in structure and function were associated with behavioural performance. Of all studies included in this systematic review, results from the highest quality studies, which were two randomized controlled trials, demonstrated that multi-domain CCT could lead to increases in hippocampal functional connectivity. Further high quality studies that include an active

Ferguson-Coleman, Emma; Keady, John; Young, Alys

2014-01-01

This study concerns culturally Deaf people in the United Kingdom who use British Sign Language (BSL). Its objective was to explore how Deaf people's knowledge about dementia and access to services is mediated by their minoritised cultural-linguistic status. Twenty-six members of the Deaf community participated in one of three Deaf-led focus groups in BSL corresponding with the sample of: Deaf people over the age of 60 without dementia; Deaf people aged 18-60 working professional roles unconnected with dementia services; ordinary members of the Deaf community aged 18-60. Data were subjected to a thematic content analysis. Participants' concerns about their poor levels of knowledge and understanding of dementia were augmented by their awareness that without sustained social contact in BSL opportunities for earlier recognition of dementia would be lost. Although primary care services were identified as the first port of call for dementia-related concerns, there was widespread mistrust of their effectiveness because of failures in communication and cultural competence. Confirmed diagnosis of dementia was not viewed as a gateway to services and support because Deaf organisations, dementia-related organisations and mainstream adult services were perceived to be ill-equipped to respond to the needs of Deaf people with dementia. Locating problems of late diagnosis within the Deaf community's poor awareness and knowledge of dementia fails to recognise the structural barriers Deaf people face in timely access to services and accurate recognition of dementia-related changes.

Calendar systems and communication of deaf-blind children

Directory of Open Access Journals (Sweden)

Jablan Branka

2012-01-01

Full Text Available The aim of this paper is to explain the calendar systems and their role in teaching deaf-blind children. Deaf-blind persons belong to a group of multiple disabled persons. This disability should not be observed as a simple composite of visual and hearing impairments, but as a combination of sensory impairments that require special assistance in the development, communication and training for independent living. In our environment, deaf-blind children are being educated in schools for children with visual impairments or in schools for children with hearing impairments (in accordance with the primary impairment. However, deaf-blind children cannot be trained by means of special programs for children with hearing impairment, visual impairment or other programs for students with developmental disabilities without specific attention required by such a combination of sensory impairments. Deaf-blindness must be observed as a multiple impairment that requires special work methods, especially in the field of communication, whose development is severely compromised. Communication skills in deaf-blind people can be developed by using the calendar systems. They are designed in such a manner that they can be easily attainable to children with various sensory impairments. Calendars can be used to encourage and develop communication between adult persons and a deaf-blind child.

Full Text Available The present study examined differences in modality use during episodes of joint attention between hearing parent-hearing child dyads and hearing parent-deaf child dyads. Hearing children were age-matched to deaf children. Dyads were video recorded in a free play session with analyses focused on uni- and multimodality use during joint attention episodes. Results revealed that adults in hearing parent-deaf child dyads spent a significantly greater proportion of time interacting with their children using multiple communicative modalities than adults in hearing parent-hearing child dyads, who tended to use the auditory modality (e.g., oral language most often. While these findings demonstrate that hearing parents accommodate their children's hearing status, we observed greater overall time spent in joint attention in hearing parent-hearing child dyads than hearing parent-deaf child dyads. Our results point to important avenues for future research on how parents can better accommodate their child’s hearing status through the use of multimodal communication strategies.

Tactile memory of deaf-blind adults on four tasks.

Arnold, Paul; Heiron, Karen

2002-02-01

The performance of ten deaf-blind and ten sighted-hearing participants on four tactile memory tasks was investigated. Recognition and recall memory tasks and a matching pairs game were used. It was hypothesized that deaf-blind participants would be superior on each task. Performance was measured in terms of the time taken, and the number of items correctly recalled. In Experiments 1 and 2, which measured recognition memory in terms of the time taken to remember target items, the hypothesis was supported, but not by the length of time taken to recognize the target items, or for the number of target items correctly identified. The hypothesis was supported by Experiment 3, which measured recall memory, with regard to time taken to complete some of the tasks but not for the number of correctly recalled positions. Experiment 4, which used the matching pairs game, supported the hypothesis in terms of both time taken and the number of moves required. It is concluded that the deaf-blind people's tactile encoding is more efficient than that of sighted-hearing people, and that it is probable that their storage and retrieval are normal.

Maiorana-Basas, Michella; Pagliaro, Claudia M

2014-07-01

As society becomes increasingly more dependent on technology, information regarding the use, preference, and accessibility of commonly used devices and services among individuals who are deaf and hard of hearing (DHH) is crucial. Developing technologies that are functional and appropriately accessible allows persons who are DHH to fully participate in society, education, and business while also providing opportunities for personal and professional advancement. Although a few international studies have addressed the technology use of individuals who are DHH, none exist that focus on the needs, preferences, and accessibility of current Internet- and mobile-based technologies. Consequently, a national survey was conducted in the United States to determine the preference, frequency of use, and accessibility of various technologies (hardware, software, Web sites) by adults who are DHH and living in the United States. Findings indicate frequent use of smartphones and personal computers, specifically for text-based communication and web surfing, and little use of Teletypewriter/Telecommunications Device for the Deaf. Web site feature preferences include pictures and text, and captions over signed translations. Some results varied by demographics. © The Author 2014. Published by Oxford University Press.

2006-12-01

Full Text Available ABSTRACT: The knowledge of LIBRAS – Brazilian Sign Language – is determining to the process of structuring the discursive formations and to the constitution of the deaf one. The present work aims to discuss the LIBRAS as an important tool of structuring the discursive of the deaf individual an as a facilitating factor in the description of his health problems. The data constitute two texts, one of them wrote by a deaf skilled in LIBRAS and the other wrote by a deaf who does not express himself in this kind of language. It was verified that the first text’s author is consistent, has mobility and moves easily through the discursive formations, but otherwise is the text belonging to the other patient. It can be stated that the Brazilian sign language – LIBRAS – is a decisive tool in the working out of the deaf discursive formations and the comprehension of his discourse by the health area professionals provide a larger understanding of the constitution of the deaf identity, a fundamental aspect for an improvement in the services offered in the health area.

2018-01-01

Culturally, hearing children born to Deaf parents may have to mediate two different positions within the hearing and Deaf cultures. However, there appears to be little written about the experiences of hearing children born to Deaf parents in the South African context. This study sought to investigate the roles of children of Deaf adults (CODAs) as interpreters in Deaf-parented families, more specifically, the influence of gender and birth order in language brokering. Two male and eight female participants between the ages of 21 and 40 years were recruited through purposive and snowball sampling strategies. A qualitative design was employed and data were collected using a semi-structured, open-ended interview format. Themes which emerged were analysed using thematic analysis. The findings indicated that there was no formal assignment of the interpreter role; however, female children tended to assume the role of interpreter more often than the male children. Also, it appeared as though the older children shifted the responsibility for interpreting to younger siblings. The participants in this study indicated that they interpreted in situations where they felt they were not developmentally or emotionally ready, or in situations which they felt were better suited for older siblings or for siblings of another gender. This study highlights a need for the formalisation of interpreting services for Deaf people in South Africa in the form of professional interpreters rather than the reliance on hearing children as interpreters in order to mediate between Deaf and hearing cultures.

Taneja, M K

2014-12-01

Hearing is an essential sensory sense of an individual for development of speech which is crucial for verbal communication and personality development. It is the second most common form of disability after loco motor disability in India. Disabling hearing loss is more than 40 dB hearing loss in better ear in a person more than 15 years of age and greater than 30 dB hearing loss in better hearing ear below 14 years of age. WHO estimated 360 million individuals in the world with disabling hearing loss, out of which 91 % are adults and only 9 % are children. Early and accurate identification of birth asphyxia, hyperbilirubinemia, auditory neuropathy Presbyacusis and avoiding noise pollution and discouraging use of mobile phone, tobacco chewing/smoking, in those who are prone to deafness, an intervention is a must to decrease deafness from our society. Deafness prevention can only be possible with mutual cooperation with dedication of different medical and non-medical personnel and also by helping the persons with deafness. We have to focus not only on the children but also on senior citizens as most alarming, up to 40 %, incidence of deafness is in senior citizens above the age of 75 years. Timely cure and preventive measures are essential for better socio-economic state of the country. By helping the persons with deafness, we will not only be doing a great service to the Nation but also to the society at large.

Sensory-motor relationships in speech production in post-lingually deaf cochlear-implanted adults and normal-hearing seniors: Evidence from phonetic convergence and speech imitation.

Scarbel, Lucie; Beautemps, Denis; Schwartz, Jean-Luc; Sato, Marc

2017-07-01

Speech communication can be viewed as an interactive process involving a functional coupling between sensory and motor systems. One striking example comes from phonetic convergence, when speakers automatically tend to mimic their interlocutor's speech during communicative interaction. The goal of this study was to investigate sensory-motor linkage in speech production in postlingually deaf cochlear implanted participants and normal hearing elderly adults through phonetic convergence and imitation. To this aim, two vowel production tasks, with or without instruction to imitate an acoustic vowel, were proposed to three groups of young adults with normal hearing, elderly adults with normal hearing and post-lingually deaf cochlear-implanted patients. Measure of the deviation of each participant's f 0 from their own mean f 0 was measured to evaluate the ability to converge to each acoustic target. showed that cochlear-implanted participants have the ability to converge to an acoustic target, both intentionally and unintentionally, albeit with a lower degree than young and elderly participants with normal hearing. By providing evidence for phonetic convergence and speech imitation, these results suggest that, as in young adults, perceptuo-motor relationships are efficient in elderly adults with normal hearing and that cochlear-implanted adults recovered significant perceptuo-motor abilities following cochlear implantation.

Variation in genes related to cochlear biology is strongly associated with adult-onset deafness in border collies.

Full Text Available Domestic dogs can suffer from hearing losses that can have profound impacts on working ability and quality of life. We have identified a type of adult-onset hearing loss in Border Collies that appears to have a genetic cause, with an earlier age of onset (3-5 years than typically expected for aging dogs (8-10 years. Studying this complex trait within pure breeds of dog may greatly increase our ability to identify genomic regions associated with risk of hearing impairment in dogs and in humans. We performed a genome-wide association study (GWAS to detect loci underlying adult-onset deafness in a sample of 20 affected and 28 control Border Collies. We identified a region on canine chromosome 6 that demonstrates extended support for association surrounding SNP Chr6.25819273 (p-value = 1.09 × 10(-13. To further localize disease-associated variants, targeted next-generation sequencing (NGS of one affected and two unaffected dogs was performed. Through additional validation based on targeted genotyping of additional cases (n = 23 total and controls (n = 101 total and an independent replication cohort of 16 cases and 265 controls, we identified variants in USP31 that were strongly associated with adult-onset deafness in Border Collies, suggesting the involvement of the NF-κB pathway. We found additional support for involvement of RBBP6, which is critical for cochlear development. These findings highlight the utility of GWAS-guided fine-mapping of genetic loci using targeted NGS to study hereditary disorders of the domestic dog that may be analogous to human disorders.

Outcomes of cochlear implantation in deaf children of deaf parents: comparative study.

Hassanzadeh, S

2012-10-01

This retrospective study compared the cochlear implantation outcomes of first- and second-generation deaf children. The study group consisted of seven deaf, cochlear-implanted children with deaf parents. An equal number of deaf children with normal-hearing parents were selected by matched sampling as a reference group. Participants were matched based on onset and severity of deafness, duration of deafness, age at cochlear implantation, duration of cochlear implantation, gender, and cochlear implant model. We used the Persian Auditory Perception Test for the Hearing Impaired, the Speech Intelligibility Rating scale, and the Sentence Imitation Test, in order to measure participants' speech perception, speech production and language development, respectively. Both groups of children showed auditory and speech development. However, the second-generation deaf children (i.e. deaf children of deaf parents) exceeded the cochlear implantation performance of the deaf children with hearing parents. This study confirms that second-generation deaf children exceed deaf children of hearing parents in terms of cochlear implantation performance. Encouraging deaf children to communicate in sign language from a very early age, before cochlear implantation, appears to improve their ability to learn spoken language after cochlear implantation.

Objective This study sought to investigate the roles of children of Deaf adults (CODAs) as interpreters in Deaf-parented families, more specifically, the influence of gender and birth order in language brokering. Method Two male and eight female participants between the ages of 21 and 40 years were recruited through purposive and snowball sampling strategies. A qualitative design was employed and data were collected using a semi-structured, open-ended interview format. Themes which emerged were analysed using thematic analysis. Results The findings indicated that there was no formal assignment of the interpreter role; however, female children tended to assume the role of interpreter more often than the male children. Also, it appeared as though the older children shifted the responsibility for interpreting to younger siblings. The participants in this study indicated that they interpreted in situations where they felt they were not developmentally or emotionally ready, or in situations which they felt were better suited for older siblings or for siblings of another gender. Conclusion This study highlights a need for the formalisation of interpreting services for Deaf people in South Africa in the form of professional interpreters rather than the reliance on hearing children as interpreters in order to mediate between Deaf and hearing cultures.

People who are deaf use health care services differently than the general population; little research has been carried out to understand the reasons. To better understand the health care experiences of deaf people who communicate in American Sign Language. Qualitative analyses of focus group discussions in 3 U.S. cities. Ninety-one deaf adults who communicate primarily in American Sign Language. We collected information about health care communication and perceptions of clinicians' attitudes. We elicited stories of both positive and negative encounters, as well as recommendations for improving health care. Communication difficulties were ubiquitous. Fear, mistrust, and frustration were prominent in participants' descriptions of health care encounters. Positive experiences were characterized by the presence of medically experienced certified interpreters, health care practitioners with sign language skills, and practitioners who made an effort to improve communication. Many participants acknowledged limited knowledge of their legal rights and did not advocate for themselves. Some participants believed that health care practitioners should learn more about sociocultural aspects of deafness. Deaf people report difficulties using health care services. Physicians can facilitate change to improve this. Future research should explore the perspective of clinicians when working with deaf people, ways to improve communication, and the impact of programs that teach deaf people self-advocacy skills and about their legal rights.

Domestic dogs can suffer from hearing losses that can have profound impacts on working ability and quality of life. We have identified a type of adult-onset hearing loss in Border Collies that appears to have a genetic cause, with an earlier age of onset (3–5 years) than typically expected for aging dogs (8–10 years). Studying this complex trait within pure breeds of dog may greatly increase our ability to identify genomic regions associated with risk of hearing impairment in dogs and in humans. We performed a genome-wide association study (GWAS) to detect loci underlying adult-onset deafness in a sample of 20 affected and 28 control Border Collies. We identified a region on canine chromosome 6 that demonstrates extended support for association surrounding SNP Chr6.25819273 (p-value = 1.09×10−13). To further localize disease-associated variants, targeted next-generation sequencing (NGS) of one affected and two unaffected dogs was performed. Through additional validation based on targeted genotyping of additional cases (n = 23 total) and controls (n = 101 total) and an independent replication cohort of 16 cases and 265 controls, we identified variants in USP31 that were strongly associated with adult-onset deafness in Border Collies, suggesting the involvement of the NF-κB pathway. We found additional support for involvement of RBBP6, which is critical for cochlear development. These findings highlight the utility of GWAS–guided fine-mapping of genetic loci using targeted NGS to study hereditary disorders of the domestic dog that may be analogous to human disorders.

A postlingually deaf patient who receives a cochlear implant (CI) acquires multiple benefits, not just audiological but also nonaudiological: improvement in quality of life, psychological well-being, and social interaction. The aim of the study was to ascertain the relationship between the CI satisfaction experienced by adult, postlingually deaf individuals and their level of psychological distress, stress coping strategies, and global self-esteem. We also considered sociodemographic variables (such as sex, age, education, marital/partner status, and employment/study status), variables related to their deafness, and their length of experience with a CI. The study had a cross-sectional design in which participants were asked to fill in a mailed personal inquiry form seeking sociodemographic data and one question related to CI satisfaction, and the following questionnaires: General Health Questionnaire-28, the Brief Coping Orientation to Problems Experienced, and the Rosenberg Self-Esteem Scale. This study included 98 patients with postlingual deafness between 19 and 85 years old who had unilateral CIs. For some analyses, the patients were also divided into two groups: younger (≤60 years) and older (>60 years). Two other subgroups were those with shorter CI experience (1 to 2 years) and those with longer CI experience (5 to 6 years). As an objective reference, speech perception scores in quiet and in noise were also used. The majority of postlingually deaf subjects rated their CI satisfaction as high or very high, and this was at similar levels in younger and older subjects, as well as in those who had used CIs for either a short or a long time. CI satisfaction was not related to speech perception scores, duration of deafness, length of CI use, or other sociodemographic factors. Positive self-esteem, having less severe symptoms of depression, and the use of humor or self-distraction were conducive to CI satisfaction. Using a coping strategy of denial had a negative

Congenital Deafness Reduces, But Does Not Eliminate Auditory Responsiveness in Cat Extrastriate Visual Cortex.

Congenital deafness not only affects the development of the auditory cortex, but also the interrelation between the visual and auditory system. For example, congenital deafness leads to visual modulation of the deaf auditory cortex in the form of cross-modal plasticity. Here we asked, whether congenital deafness additionally affects auditory modulation in the visual cortex. We demonstrate that auditory activity, which is normally present in the lateral suprasylvian visual areas in normal hearing cats, can also be elicited by electrical activation of the auditory system with cochlear implants. We then show that in adult congenitally deaf cats auditory activity in this region was reduced when tested with cochlear implant stimulation. However, the change in this area was small and auditory activity was not completely abolished despite years of congenital deafness. The results document that congenital deafness leads not only to changes in the auditory cortex but also affects auditory modulation of visual areas. However, the results further show a persistence of fundamental cortical sensory functional organization despite congenital deafness. Copyright © 2018 The Authors. Published by Elsevier Ltd..

2012-01-01

The purpose of this study was to examine the musical engagement (participation and attitude) of pediatric CI recipients who were implanted during early childhood and who have reached age 15 or older. A questionnaire was administered to a group of 31 prelingually deaf CI users who receive annual follow up services and assessment in a clinical research center. The questionnaire was used to examine involvement in and attitudes toward music in school, the community, and in the home; social affiliation (hearing, Deaf, both) and mode of communication (oral, manual, both) were also examined. Despite the technical limitations of cochlear implants in transmitting pitch, melody, and tone quality, over two thirds of this sample described music as being important or very important in their lives. A high level of past and present familial involvement in music was associated with higher levels of current involvement and importance of music in the lives of adolescent and young adult CI users. Comparisons were noted with data from prior studies of persons with hearing loss who were non-CI users. PMID:23565029

Full Text Available The work market is a field of extreme importance and concern towards the society, such being the case, the training of the worker must be constantly present in the labor life of this worker. Before this, we question ourselves about the existing relation between the training of the instructor and the work market for the deaf and how this occurs. By means of the investigation of the speech about the identity, the deafness and the work we seek to understand the constitution of the deaf workers performing a semi - structured interview with a deaf adult. This study allowed us a better clearing about the professional preparation of the deaf people, making such as inquiries about the relationship existing between the training of the deaf instructor and the market of work to be best exemplified. Through the interview we could elucidate our personal and academic questionings and realize the importance of this insertion and of its pairs in the work market, just as the methods that could and/ or should be used for this to occur.

To explored the significance of screening the gene mutations of deafness related in deaf-mute (deaf & dumb) family using DNA microarray. Total of 52 couples of deaf-mute were recruited from Changchun deaf-mute community. With an average age of (58.3 ± 6.7) years old (x(-) ± s). Blood samples were obtained with informed consent. Their genomic DNA was extracted from peripheral blood and PCR was performed. Nine of hot spot mutations in four most common deafness pathologic gene were examined with the DNA microarray, including GJB2, GJB3, PDS and mtDNA 12S rRNA genes. At the same time, the results were verified with the traditional methods of sequencing. Fifty of normal people served as a control group. All patients were diagnosed non-syndromic sensorineural hearing loss by subjective pure tone audiometry. Thirty-two of 104 cases appeared GJB2 gene mutation (30.7%), the mutation sites included 35delG, 176del16, 235delC and 299delAT. Eighteen of 32 cases of GJB2 mutations were 235delC (59.1%). Seven of 104 cases appeared SLC26A4 gene IVS7-2 A > G mutation. Questionnaire survey and gene diagnosis revealed that four of 52 families have deaf offspring (7.6%). When a couple carries the same gene mutation, the risk of their children deafness was 100%. The results were confirmed with the traditional methods of sequencing. There is a high risk of deafness if a deaf-mute family is planning to have a new baby. It is very important and helpful to avoid deaf newborns again in deaf-mute family by DNA microarray.

Munro-Ludders, Bruce; Simpatico, Thomas; Zvetina, Daria

2004-01-01

Illinois Deaf Services 2000 (IDS2000), a public/private partnership, promotes the creation and implementation of strategies to develop and increase access to mental health services for deaf, hard of hearing, late-deafened, and deaf-blind consumers. IDS2000 has resulted in the establishment of service accessibility standards, a technical support and adherence monitoring system, and the beginnings of a statewide telepsychiatry service. These system modifications have resulted in increase by 60% from baseline survey data in the number of deaf, hard of hearing, late-deafened, and deaf-blind consumers identified in community mental-health agencies in Illinois. Depending on the situation of deaf services staff and infrastructure, much of IDS2000 could be replicated in other states in a mostly budget-neutral manner.

Benton visual test was performed by two different ways on 46 students of primary school. (22 deaf and 24 normal students. The t-student was used to analysis the data. Results: The visual memory in deaf students was significantly higher than the similar normal students (not deaf.While the action of visual memory in deaf girls was risen in comparison to normal girls in both ways, the deaf boys presented the better action in just one way of the two performances of Benton visual memory test.Conclusion: The action of plasticity of brain shows that the brain of an adult is dynamic and there are some changes in it. This brain plasticity has not limited to sensory somatic systems. Therefore according to plasticity of cortical brain theory, the deaf students due to the defect of hearing have increased the visual the visual inputs which developed the procedural visual memory.

Using functional magnetic resonance imaging (fMRI), we neuroimaged deaf adults as they performed two linguistic tasks with sentences in American Sign Language, grammatical judgment and phonemic-hand judgment. Participants' age-onset of sign language acquisition ranged from birth to 14 years; length of sign language experience was substantial and did not vary in relation to age of acquisition. For both tasks, a more left lateralized pattern of activation was observed, with activity for grammatical judgment being more anterior than that observed for phonemic-hand judgment, which was more posterior by comparison. Age of acquisition was linearly and negatively related to activation levels in anterior language regions and positively related to activation levels in posterior visual regions for both tasks.

Toyomura, Akira; Fujii, Tetsunoshin; Yokosawa, Koichi; Kuriki, Shinya

2018-03-15

Affective states, such as anticipatory anxiety, critically influence speech communication behavior in adults who stutter. However, there is currently little evidence regarding the involvement of the limbic system in speech disfluency during interpersonal communication. We designed this neuroimaging study and experimental procedure to sample neural activity during interpersonal communication between human participants, and to investigate the relationship between the amygdala activity and speech disfluency. Participants were required to engage in live communication with a stranger of the opposite sex in the MRI scanner environment. In the gaze condition, the stranger gazed at the participant without speaking, while in the live conversation condition, the stranger asked questions that the participant was required to answer. The stranger continued to gaze silently at the participant while the participant answered. Adults who stutter reported significantly higher discomfort than fluent controls during the experiment. Activity in the right amygdala, a key anatomical region in the limbic system involved in emotion, was significantly correlated with stuttering occurrences in adults who stutter. Right amygdala activity from pooled data of all participants also showed a significant correlation with discomfort level during the experiment. Activity in the prefrontal cortex, which forms emotion regulation neural circuitry with the amygdala, was decreased in adults who stutter than in fluent controls. This is the first study to demonstrate that amygdala activity during interpersonal communication is involved in disfluent speech in adults who stutter. Copyright © 2018 IBRO.

Bola, Łukasz; Zimmermann, Maria; Mostowski, Piotr; Jednoróg, Katarzyna; Marchewka, Artur; Rutkowski, Paweł; Szwed, Marcin

2017-01-24

The principles that guide large-scale cortical reorganization remain unclear. In the blind, several visual regions preserve their task specificity; ventral visual areas, for example, become engaged in auditory and tactile object-recognition tasks. It remains open whether task-specific reorganization is unique to the visual cortex or, alternatively, whether this kind of plasticity is a general principle applying to other cortical areas. Auditory areas can become recruited for visual and tactile input in the deaf. Although nonhuman data suggest that this reorganization might be task specific, human evidence has been lacking. Here we enrolled 15 deaf and 15 hearing adults into an functional MRI experiment during which they discriminated between temporally complex sequences of stimuli (rhythms). Both deaf and hearing subjects performed the task visually, in the central visual field. In addition, hearing subjects performed the same task in the auditory modality. We found that the visual task robustly activated the auditory cortex in deaf subjects, peaking in the posterior-lateral part of high-level auditory areas. This activation pattern was strikingly similar to the pattern found in hearing subjects performing the auditory version of the task. Although performing the visual task in deaf subjects induced an increase in functional connectivity between the auditory cortex and the dorsal visual cortex, no such effect was found in hearing subjects. We conclude that in deaf humans the high-level auditory cortex switches its input modality from sound to vision but preserves its task-specific activation pattern independent of input modality. Task-specific reorganization thus might be a general principle that guides cortical plasticity in the brain.

Music and Deaf Culture: Images from the Media and Their Interpretation by Deaf and Hearing Students.

Science.gov (United States)

Darrow; Loomis

1999-01-01

The purpose of the study was threefold: (a) to examine how the visual media have portrayed the subject of music and the deaf, (b) to verify the validity of these portrayals with members of the deaf community, and (c) to compare and contrast deaf and hearing audiences' impressions of these portrayals. An additional purpose of the research was to examine the results in light of possible misconceptions that may be construed by music therapists and music educators based upon the media's representation of the relationship between music and deaf culture. Since music therapists and music educators are the primary persons responsible for the music instruction of students in school programs for deaf and hard-of-hearing students, it is particularly important that they receive accurate messages about the relationship of music to deaf culture. Fifty deaf (n = 25) and hearing (n = 25) undergraduate college students individually viewed motion picture and television excerpts related to music and the deaf. Subjects were instructed to take notes as needed regarding the content of each excerpt and their impressions. Students were then interviewed in their native language, English or American Sign Language, as to their interpretations and perceptions regarding these excerpts and their accuracy. Interviews of the deaf students were translated into English from American Sign Language by trained interpreters. Written transcriptions were then made of the interpreters' English translations of the interviews with deaf students and of the verbal interviews with hearing students. Interview transcripts from both groups were coded and analyzed for recurring themes and patterns using content analysis. Data analysis revealed cultural patterns for the two groups, impressions specific to individual subjects, and trends in communication style and content for the two groups. Implications for music therapists and music educators are given regarding the influence of the media, characteristics of deaf

2015-01-01

This article reviews neuroimaging studies that inform psychotherapy research. An introduction to neuroimaging methods is provided as background for the increasingly sophisticated breadth of methods and findings appearing in psychotherapy research. We compiled and assessed a comprehensive list of neuroimaging studies of psychotherapy outcome, along with selected examples of other types of studies that also are relevant to psychotherapy research. We emphasized magnetic resonance imaging (MRI) since it is the dominant neuroimaging modality in psychological research. We summarize findings from neuroimaging studies of psychotherapy outcome, including treatment for depression, obsessive compulsive disorder (OCD), and schizophrenia. The increasing use of neuroimaging methods in the study of psychotherapy continues to refine our understanding of both outcome and process. We suggest possible directions for future neuroimaging studies in psychotherapy research.

In the last decade, the rehabilitation of postlingually deaf adults and prelingually deaf children with cochlear implants has been established as a treatment of deafness. The technological development of the implant devices and improvement of the surgical technique have led to a considerable increase of hearing performance during the last years. The postlingually deaf adults are able to use the telephone and may be integrated in their original job. Prelingually deaf children can even visit normal schools after cochlear implantation and hearing rehabilitation training. In order to preoperatively establish the state of the cochlear, radiological diagnosis of the temporal bone is necessary. High resolution computerized tomography imaging of the temporal bone with coronar and axial 1 mm slices and MRI with thin slice technique (three dimensional, T2 weighted turbo-spinecho sequence with 0.7 mm slices) have proved to be valuable according to our experience. Furthermore a postoperative synoptical X-ray, in a modified Chausse III projection, offers good information about the position of the implant and insertion of the stimulating electrode into the cochlea.

Hypoparathyroidism, deafness, and renal dysplasia (HDR) syndrome is an autosomal dominant disorder caused by a GATA3 gene mutation. Here we report a novel mutation of GATA3 in a patient diagnosed with HDR syndrome at the age of 58 with extensive intracranial calcification. A 58-year-old Japanese man showed severe hypocalcemia and marked calcification in the basal ganglia, cerebellum, deep white matter, and gray-white junction on computed tomography (CT). The serum intact parathyroid hormone level was relatively low against low serum calcium concentration. The patient had been diagnosed with bilateral sensorineural deafness in childhood and had a family history of hearing disorders. Imaging studies revealed no renal anomalies. The patient was diagnosed with HDR syndrome, and genetic testing was performed. Genetic analysis of GATA3 showed a novel nonsense mutation at codon 198 (S198X) in exon 3. The S198X mutation leads to a loss of two zinc finger deoxyribonucleic acid (DNA) binding domains and is considered to be responsible for HDR syndrome. We identified a novel nonsense mutation of GATA3 in an adult patient with HDR syndrome who showed extensive intracranial calcification.

Armstrong, F; Heidingsfeld, V

2000-11-01

This article looks at ways in which aromatherapy and therapeutic massage have been found to be beneficial for a group of deaf and deafblind adults with special needs, living in residential accommodation. Our basic aim is to promote confidence and communication as well as enhancing a sense of well-being through the judicial use of aromatic plant materials and therapeutic massage. Aromatherapy sessions have become an accepted enjoyable and therapeutic part of the residents' lifestyle. It is our belief that this gentle, non-invasive therapy can benefit deaf and deafblind people, especially as their intact senses can be heightened. This paper explores both professional and caring issues related to the use of aromatherapy in this environment.

Multiple Neuroimaging Measures for Examining Exercise-induced Neuroplasticity in Older Adults: A Quasi-experimental Study

Directory of Open Access Journals (Sweden)

Lihong Wang

2017-04-01

Full Text Available Physical exercise can improve physical and mental health. A number of imaging studies have examined the role of neuroplasticity in improving cognition with physical exercise; however, such neuroplasticity changes are not consistent across the reports partly due to small sample sizes in some studies. We thought to explore the concept that identifying consistent findings across multi-modality imaging measures would provide relatively reliable results. We designed a 6-week quasi-experiment with Wii-fitness exercise program in 24 healthy adults older than 60, and then examined the changes on neuroimaging measures including brain volume, the amplitude of low-frequency oscillation function (ALFF, regional homogeneity (ReHo, seed-based functional connectivity (FC, and the global efficiency of nodal connectivity during resting state. We focused on whether there were common regions showing changes after exercise across these measures and which measure was closely correlated with cognitive improvement. After the six-week exercise program, participants demonstrated a significant improvement in memory and executive function on neuropsychological tests, and in memory recall on an emotional memory task. The common brain regions that showed significant changes across different measures were the right striatum and the posterior cingulate (PCC. After exercise, the PCC showed decreased ReHo and increased volume, and the striatum did not show volume loss as the control group did and increased its FC with the cingulate, temporal, parietal, and occipital regions. Moreover, the connectivity change between the striatum and the thalamus was correlated with the improvement of executive function. This result implicates the striatum and the PCC associated network in physical exercise. Our work highlights the effectiveness of multi-modality neuroimaging measures in investigating neuroplasticity.

Neuroimaging in Antisocial Personality Disorder

Full Text Available Neuroimaging has been used in antisocial personality disorder since the invention of computed tomography and new modalities are introduced as technology advances. Magnetic resonance imaging, diffusion tensor imaging, functional magnetic resonance imaging and radionuclide imaging are such techniques that are currently used in neuroimaging. Although neuroimaging is an indispensible tool for psychiatric reseach, its clinical utility is questionable until new modalities become more accessible and regularly used in clinical practice. The aim of this paper is to provide clinicians with an introductory knowledge on neuroimaging in antisocial personality disorder including basic physics principles, current contributions to general understanding of pathophysiology in antisocial personality disorder and possible future applications of neuroimaging.

Augmented Input Reveals Word Deafness in a Man with Frontotemporal Dementia

Directory of Open Access Journals (Sweden)

Chris Gibbons

2012-01-01

Full Text Available We describe a 57 year old, right handed, English speaking man initially diagnosed with progressive aphasia. Language assessment revealed inconsistent performance in key areas. Expressive language was reduced to a few short, perseverative phrases. Speech was severely apraxic. Primary modes of communication included gesture, pointing, gaze, physical touch and leading. Responses were 100% accurate when he was provided with written words, with random or inaccurate responses for strictly auditory/verbal input. When instructions to subsequent neuropsychological tests were written instead of spoken, performance improved markedly. A comprehensive audiology assessment revealed no hearing impairment. Neuroimaging was unremarkable. Neurobehavioral evaluation utilizing written input led to diagnoses of word deafness and frontotemporal dementia, resulting in very different management. We highlight the need for alternative modes of language input for assessment and treatment of patients with language comprehension symptoms.

I Like You More if I Think You Like Me: The Effect of Metastereotypes on Attitudes Toward People With Deafness.

Science.gov (United States)

Matera, Camilla; Dalla Verde, Sara; Meringolo, Patrizia

2015-01-01

In the present article we aimed at investigating the role of metastereotypes and gender on hearing people's attitudes towards people with deafness. Ninety-six Italian hearing adults participated in a 2 × 2 experimental study. Participants were presented with the results of a fictitious but apparently real survey concerning the opinions people with deafness have of hearing people. Metastereotypes (positive vs. negative) were manipulated through this presentation. Results showed that metastereotypes interacted with participants' gender in determining their attitudes towards people with deafness: when positive metastereotypes were activated, women's attitudes appeared more favorable toward people with deafness if compared to the negative metastereotypes condition. No effect of metastereotypes was observed among male participants. In conclusion, the activation of metastereotypes can be a useful means in intervening to improve attitudes toward people with deafness.

Silencing Deafness: Displacing Disability in the Nineteenth Century

Directory of Open Access Journals (Sweden)

Esme Cleall

2015-03-01

Full Text Available This article traces the way in which the language of displacement and silence were used in nineteenth-century discussions of deafness and connects this tendency to the marginalised place deaf experience occupies historically. Throughout the nineteenth century, a period which saw the consolidation of ‘the deaf and dumb’ as a social category, the word ‘forgetting’ crept into numerous discussions of deafness by both deaf and hearing commentators. Some, such as the educationalist Alexander Graeme Bell, were overt in their desire to forget deafness, demanding disability was ‘bred out’ and deaf culture condemned to the forgotten past. Others used the term ambivalently and sometimes metaphorically discussing the deaf as ‘forgotten’ by society, and ‘children of silence’. Some even pleaded that people who were deaf were not forgotten. But, though varied, the use of the imagery of forgetting and silence to evoke deafness is recurrent, and may, therefore, be seen to reveal something about how deaf experience can be approached as a displacement where deafness was spatially and imaginatively marginalised. I argue that one of the consequences of the conceptual framing of deafness through the language of forgetting was actively to silence deafness and to neutralise the idea that disability should be marginal and could be forgotten.

Visual Word Recognition in Deaf Readers: Lexicality Is Modulated by Communication Mode

Barca, Laura; Pezzulo, Giovanni; Castrataro, Marianna; Rinaldi, Pasquale; Caselli, Maria Cristina

2013-01-01

Evidence indicates that adequate phonological abilities are necessary to develop proficient reading skills and that later in life phonology also has a role in the covert visual word recognition of expert readers. Impairments of acoustic perception, such as deafness, can lead to atypical phonological representations of written words and letters, which in turn can affect reading proficiency. Here, we report an experiment in which young adults with different levels of acoustic perception (i.e., hearing and deaf individuals) and different modes of communication (i.e., hearing individuals using spoken language, deaf individuals with a preference for sign language, and deaf individuals using the oral modality with less or no competence in sign language) performed a visual lexical decision task, which consisted of categorizing real words and consonant strings. The lexicality effect was restricted to deaf signers who responded faster to real words than consonant strings, showing over-reliance on whole word lexical processing of stimuli. No effect of stimulus type was found in deaf individuals using the oral modality or in hearing individuals. Thus, mode of communication modulates the lexicality effect. This suggests that learning a sign language during development shapes visuo-motor representations of words, which are tuned to the actions used to express them (phono-articulatory movements vs. hand movements) and to associated perceptions. As these visuo-motor representations are elicited during on-line linguistic processing and can overlap with the perceptual-motor processes required to execute the task, they can potentially produce interference or facilitation effects.

The deaf normally considered to be disabled that do not need any mobile technology due to the inabilities of hearing and talking. However, many deaf are using mobile phone in their daily life for various purposes such as communication and learning. Many studies have attempted to identify the need of deaf people in mobile application and level of usage of the applications. This study aims in studying the recent research conducted on deaf mobile application to understand the level of importance of mobile technology for this disabled community. This paper enable identification of studies conducted are limited and the need of more research done of this disabled people to ensure their privilege of using mobile technology and its application, which leads to the identification of deaf user requirement for mobile application as future study.

Is Visual Selective Attention in Deaf Individuals Enhanced or Deficient? The Case of the Useful Field of View

Science.gov (United States)

Dye, Matthew W. G.; Hauser, Peter C.; Bavelier, Daphne

2009-01-01

Background Early deafness leads to enhanced attention in the visual periphery. Yet, whether this enhancement confers advantages in everyday life remains unknown, as deaf individuals have been shown to be more distracted by irrelevant information in the periphery than their hearing peers. Here, we show that, in a complex attentional task, a performance advantage results for deaf individuals. Methodology/Principal Findings We employed the Useful Field of View (UFOV) which requires central target identification concurrent with peripheral target localization in the presence of distractors – a divided, selective attention task. First, the comparison of deaf and hearing adults with or without sign language skills establishes that deafness and not sign language use drives UFOV enhancement. Second, UFOV performance was enhanced in deaf children, but only after 11 years of age. Conclusions/Significance This work demonstrates that, following early auditory deprivation, visual attention resources toward the periphery slowly get augmented to eventually result in a clear behavioral advantage by pre-adolescence on a selective visual attention task.

On the possibilities and limits of "DEAF DEAF SAME": Tourism and empowerment camps in Adamorobe (Ghana, Bangalore and Mumbai (India.

Directory of Open Access Journals (Sweden)

Michele Ilana Friedner

2014-06-01

Full Text Available This article qualitatively analyzes the ways that the discourse of "deaf universalism" circulates within two common deaf practices: tourism and engaging in interventions. Arguing that the largely Northern-situated discipline of Deaf Studies does not adequately examine how deaf bodies and discourses travel, ethnographic data compiled in India and Ghana during transnational encounters is employed to examine how claims of "sameness" and "difference" are enacted and negotiated. Similarly, this article examines how deaf individuals and groups deploy the concepts of deaf "heavens" and "hells" to analyze their travel experiences and justify interventions. We argue that deaf travelers and those engaging in interventions, mostly from Northern countries, employ teleological concepts that they attempt to impose on deaf "others." Adopting a critical approach, this article argues for the importance of carving out a space within Deaf Studies for allowing non-Northern concepts to come to the fore.

Practical management of heterogeneous neuroimaging metadata by global neuroimaging data repositories.

Science.gov (United States)

Neu, Scott C; Crawford, Karen L; Toga, Arthur W

2012-01-01

Rapidly evolving neuroimaging techniques are producing unprecedented quantities of digital data at the same time that many research studies are evolving into global, multi-disciplinary collaborations between geographically distributed scientists. While networked computers have made it almost trivial to transmit data across long distances, collecting and analyzing this data requires extensive metadata if the data is to be maximally shared. Though it is typically straightforward to encode text and numerical values into files and send content between different locations, it is often difficult to attach context and implicit assumptions to the content. As the number of and geographic separation between data contributors grows to national and global scales, the heterogeneity of the collected metadata increases and conformance to a single standardization becomes implausible. Neuroimaging data repositories must then not only accumulate data but must also consolidate disparate metadata into an integrated view. In this article, using specific examples from our experiences, we demonstrate how standardization alone cannot achieve full integration of neuroimaging data from multiple heterogeneous sources and why a fundamental change in the architecture of neuroimaging data repositories is needed instead.

Reading the Freudian theory of sexual drives from a functional neuroimaging perspective

Directory of Open Access Journals (Sweden)

Serge eStoléru

2014-03-01

Full Text Available One of the essential tasks of neuropsychoanalysis is to investigate the neural correlates of sexual drives. Here, we consider the four defining characteristics of sexual drives as delineated by Freud: their pressure, aim, object, and source. We systematically examine the relations between these characteristics and the four-component neurophenomenological model that we have proposed based on functional neuroimaging studies, which comprises a cognitive, a motivational, an emotional and an autonomic/neuroendocrine component. Functional neuroimaging studies of sexual arousal have thrown a new light on the four fundamental characteristics of sexual drives by identifying their potential neural correlates. While these studies are essentally consistent with the Freudian model of drives, the main difference emerging between the functional neuroimaging perspective on sexual drives and the Freudian theory relates to the source of drives. From a functional neuroimaging perspective sources of sexual drives, conceived by psychoanalysis as processes of excitation occurring in a peripheral organ, do not seem, at least in adult subjects, to be an essential part of the determinants of sexual arousal. It is rather the central processing of visual or genital stimuli that gives to these stimuli their sexually arousing and sexually pleasurable character.

[History of the rehabilitation of the deaf child].

Science.gov (United States)

Noyon, P

1995-01-01

As a deaf mute, because mute and more often than not deaf, and then deaf and dumb, because deaf and therefore dumb, the deaf child inevitably deprived of spontaneous speech was considered up to the end of the middle ages as having no possibility of language or of thought, left to the sorry fate of being part of a sporadic population expressing themselves by gestures, a language bereft of past and future, understood only by a few members of the family or occasionally deaf neighbours. During the Renaissance, it appeared that with specific education the deaf child could talk, have a language, and therefore thought. Due merit must be given to 16th century Spain. In the 18th century, France discovered that gestures can also be a language, collated and constructed thanks to the collaboration of the partially deaf. From then on, gestual language flourished in America whilst the rest of Europe continued to prefer oral rehabilitation. With current medical progress, the deaf are no longer deaf. Deafness in the child still exists, however, but there are no longer any mutes. The deaf child can achieve access to language, which may be oral or gestual. The choice between these two modes of expression is still very tropical.

Quantifying tone deafness in the general population.

Sloboda, John A; Wise, Karen J; Peretz, Isabelle

2005-12-01

Many people reach adulthood without acquiring significant music performance skills (singing or instrumental playing). A substantial proportion of these adults consider that this has come about because they are "not musical." Some of these people may be "true" congenital amusics, characterized by specific and substantial anomalies in the processing of musical pitch and rhythm sequences, while at the same time displaying normal processing of speech and language. It is likely, however, that many adults who believe that they are unmusical are neurologically normal. We could call these adults "false" amusics. Acquisition of musical competence has multiple personal, social, and environmental precursors. Deficiencies in these areas may lead to lack of musical achievement, despite the fact that an individual possesses the necessary underlying capacities. Adults may therefore self-define as "unmusical" or "tone-deaf" for reasons unconnected to any underlying anomaly. This paper reports on two linked research studies. The first is an interview study with adults defining themselves as tone-deaf or unmusical. The interview schedule was designed to discover what criteria are being used in their self-definitions. Preliminary results suggest that performance criteria (e.g., judging oneself as unable to sing) play a major role, even for people who claim and demonstrate no perceptual deficits. The second study reports progress on the development of new subtests for a revised version of the Montreal Battery for the Evaluation of Amusia (MBEA, Peretz et al., 2003). This currently contains six tests that allow for the assessment of melodic perception: contour, intervals, scale, rhythm, meter, and recognition memory. The MBEA does not assess two capacities that are generally accepted as central to normal music cognition: harmony and emotion. The development and norming of the emotion subtest will be described. When completed, the MBEA(R) will form a robust screening device for use with

Against a background of an ever-increasing number of patients, new management options, and novel imaging modalities, neuroimaging is playing an increasingly important role in the diagnosis of dementia. This up-to-date, superbly illustrated book aims to provide a practical guide to the effective use of neuroimaging in the patient with cognitive decline. It sets out the key clinical and imaging features of the wide range of causes of dementia and directs the reader from clinical presentation to neuroimaging and on to an accurate diagnosis whenever possible. After an introductory chapter on the clinical background, the available ''toolbox'' of structural and functional neuroimaging techniques is reviewed in detail, including CT, MRI and advanced MR techniques, SPECT and PET, and image analysis methods. The imaging findings in normal ageing are then discussed, followed by a series of chapters that carefully present and analyze the key imaging findings in patients with dementias. A structured path of analysis follows the main presenting feature: disorders associated with primary gray matter loss, with white matter changes, with brain swelling, etc. Throughout, a practical approach is adopted, geared specifically to the needs of clinicians (neurologists, radiologists, psychiatrists, geriatricians) working in the field of dementia, for whom this book should prove an invaluable resource.

Suicide in deaf populations: a literature review

Kapur Navneet

2007-10-01

Full Text Available Abstract Background Studies have found that deaf individuals have higher rates of psychiatric disorder than those who are hearing, while at the same time encountering difficulties in accessing mental health services. These factors might increase the risk of suicide. However, the burden of suicidal behaviour in deaf people is currently unknown. The aim of the present review was to provide a summary of literature on suicidal behaviour with specific reference to deaf individuals. The objectives of the review were to establish the incidence and prevalence of suicidal behaviour in deaf populations; describe risk factors for suicidal behaviour in deaf populations; describe approaches to intervention and suicide prevention that have been used in deaf populations. Methods A number of electronic databases (e.g. Medline, PsycINFO, CINAHL, EMBASE, Dissertation Abstracts International, Web of Science, ComDisDome, ASSIA, Education Sage Full Text, Google Scholar, and the grey literature databases FADE and SIGLE were explored using a combination of key words and medical subject headings as search terms. Reference lists of papers were also searched. The Science and Social Sciences Citation Index electronic databases were used to identify studies that had cited key papers. We also contacted experts and organisations with an interest in the field. Results Very few studies focussed specifically on suicide in deaf populations. Those studies that were included (n = 13 generally involved small and unrepresentative samples. There were limited data on the rate of suicidal behaviour in deaf people. One study reported evidence of hearing impairment in 0.2% of all suicide deaths. Another found that individuals with tinnitus seen in specialist clinics had an elevated rate of suicide compared to the general population. The rates of attempted suicide in deaf school and college students during the previous year ranged from 1.7% to 18%, with lifetime rates as high as 30

Reference lists of papers were also searched. The Science and Social Sciences Citation Index electronic databases were used to identify studies that had cited key papers. We also contacted experts and organisations with an interest in the field. Very few studies focussed specifically on suicide in deaf populations. Those studies that were included (n = 13) generally involved small and unrepresentative samples. There were limited data on the rate of suicidal behaviour in deaf people. One study reported evidence of hearing impairment in 0.2% of all suicide deaths. Another found that individuals with tinnitus seen in specialist clinics had an elevated rate of suicide compared to the general population. The rates of attempted suicide in deaf school and college students during the previous year ranged from 1.7% to 18%, with lifetime rates as high as 30%. Little evidence was found to suggest that risk factors for

Approximately 10% to 14% of ischemic strokes occur in young adults. To investigate the yield of diagnostic tests, neuroimaging findings, and treatment of ischemic strokes in young adults. We retrospectively reviewed data from our Get with the Guidelines-Stroke database from 2005 through 2010. University hospital tertiary stroke center. A total of 215 consecutive inpatients aged 18 to 45 years with ischemic stroke/transient ischemic attack. The mean (SD) age was 37.5 (7) years; 51% were male. There were high incidence rates of hypertension (20%), diabetes mellitus (11%), dyslipidemia (38%), and smoking (34%). Relevant abnormalities were shown on cerebral angiography in 136 of 203 patients, on cardiac ultrasonography in 100 of 195, on Holter monitoring in 2 of 192; and on hypercoagulable panel in 30 of 189 patients. Multiple infarcts were observed in 31% and were more prevalent in individuals younger than age 35 years. Relevant arterial lesions were frequently detected in the middle cerebral artery (23%), internal carotid artery (13%), and vertebrobasilar arteries (13%). Cardioembolic stroke occurred in 47% (including 17% with isolated patent foramen ovale), and 11% had undetermined stroke etiology. The median National Institutes of Health Stroke Scale score was 3 (interquartile range, 0-9) and 81% had good outcome at hospital discharge. Of the 29 patients receiving thrombolysis (median National Institutes of Health Stroke Scale score, 14; interquartile range, 9-17), 55% had good outcome at hospital discharge and none developed symptomatic brain hemorrhage. This study shows the contemporary profile of ischemic stroke in young adults admitted to a tertiary stroke center. Stroke etiology can be determined in nearly 90% of patients with modern diagnostic tests. The causes are heterogeneous; however, young adults have a high rate of traditional vascular risk factors. Thrombolysis appears safe and short-term outcomes are favorable.

Neural networks mediating sentence reading in the deaf

2014-06-01

Full Text Available The present work addresses the neural bases of sentence reading in deaf populations. To better understand the relative role of deafness and English knowledge in shaping the neural networks that mediate sentence reading, three populations with different degrees of English knowledge and depth of hearing loss were included – deaf signers, oral deaf and hearing individuals. The three groups were matched for reading comprehension and scanned while reading sentences. A similar neural network of left perisylvian areas was observed, supporting the view of a shared network of areas for reading despite differences in hearing and English knowledge. However, differences were observed, in particular in the auditory cortex, with deaf signers and oral deaf showing greatest bilateral superior temporal gyrus (STG recruitment as compared to hearing individuals. Importantly, within deaf individuals, the same STG area in the left hemisphere showed greater recruitment as hearing loss increased. To further understand the functional role of such auditory cortex re-organization after deafness, connectivity analyses were performed from the STG regions identified above. Connectivity from the left STG toward areas typically associated with semantic processing (BA45 and thalami was greater in deaf signers and in oral deaf as compared to hearing. In contrast, connectivity from left STG toward areas identified with speech-based processing was greater in hearing and in oral deaf as compared to deaf signers. These results support the growing literature indicating recruitment of auditory areas after congenital deafness for visually-mediated language functions, and establish that both auditory deprivation and language experience shape its functional reorganization. Implications for differential reliance on semantic vs. phonological pathways during reading in the three groups is discussed.

Deaf Mothers and Breastfeeding: Do Unique Features of Deaf Culture and Language Support Breastfeeding Success?

Science.gov (United States)

Chin, Nancy P.; Cuculick, Jess; Starr, Matthew; Panko, Tiffany; Widanka, Holly; Dozier, Ann

2014-01-01

Background Deaf mothers who use American Sign Language (ASL) consider themselves a linguistic minority group, with specific cultural practices. Rarely has this group been engaged in infant-feeding research. Objectives To understand how ASL-using Deaf mothers learn about infant feeding and to identify their breastfeeding challenges. Methods Using a community-based participatory research (CBPR) approach we conducted four focus groups with Deaf mothers who had at least one child 0–5 years. A script was developed using a social ecological model (SEM) to capture multiple levels of influence. All groups were conducted in ASL, filmed, and transcribed into English. Deaf and hearing researchers analyzed data by coding themes within each SEM level. Results Fifteen mothers participated. All had initiated breastfeeding with their most recent child. Breastfeeding duration for eight of the mothers was three weeks to 12 months. Seven of the mothers were still breastfeeding, the longest for 19 months. Those mothers who breastfed longer described a supportive social environment and the ability to surmount challenges. Participants described characteristics of Deaf culture such as direct communication, sharing information, use of technologies, language access through interpreters and ASL-using providers, and strong self-advocacy skills. Finally, mothers used the sign ‘struggle’ to describe their breastfeeding experience. The sign implies a sustained effort over time which leads to success. Conclusions In a setting with a large population of Deaf women and ASL-using providers, we identified several aspects of Deaf culture and language which support BF mothers across institutional, community, and interpersonal levels of the SEM.

Analytic study of the Tadoma method: language abilities of three deaf-blind subjects.

Science.gov (United States)

Chomsky, C

1986-09-01

This study reports on the linguistic abilities of 3 adult deaf-blind subjects. The subjects perceive spoken language through touch, placing a hand on the face of the speaker and monitoring the speaker's articulatory motions, a method of speechreading known as Tadoma. Two of the subjects, deaf-blind since infancy, acquired language and learned to speak through this tactile system; the third subject has used Tadoma since becoming deaf-blind at age 7. Linguistic knowledge and productive language are analyzed, using standardized tests and several tests constructed for this study. The subjects' language abilities prove to be extensive, comparing favorably in many areas with hearing individuals. The results illustrate a relatively minor effect of limited language exposure on eventual language achievement. The results also demonstrate the adequacy of the tactile sense, in these highly trained Tadoma users, for transmitting information about spoken language sufficient to support the development of language and learning to produce speech.

Mance, Jennifer; Edwards, Lindsey

2012-05-01

This study aimed to examine the relationship between psychological well-being and self-perception in adolescents with cochlear implants, in relation to their perceptions of hearing, deaf signing, and orally communicating deaf peers. Self-perceptions were examined in 22 cochlear implant users aged 12-18 years, using the repertory grid technique that allows the respondent to generate personally relevant 'identity' constructs. Psychological well-being was assessed using the Beck Youth Inventory, a series of five self-report questionnaires assessing anxiety, depression, disruptive behaviour, anger, and self-esteem. Correlational analyses indicated that perceiving oneself as close to any peer, irrespective of which peer, was associated with better psychological well-being. There was also a significant positive association between perceived degree of similarity specifically to hearing peers, and psychological well-being. The closer the implanted adolescents perceived themselves to be to their hearing peers, the better their overall psychological well-being. In contrast, perceiving oneself as more similar to deaf signing peers or deaf oral peers was not significantly associated with psychological well-being. The findings are discussed in the context of previous research on social comparison, Deaf identity, and the aims of cochlear implantation.

``I Have Been Given the Power to Teach. The Children Understand Me Very Well.'' The Social and Academic Impact of Deaf Teacher Training in Kenya

Science.gov (United States)

Johnstone, Christopher; Corce, Heidi

2010-02-01

Kenya has 41 Deaf schools that serve children from Class 1 through secondary school. These schools are all characterised by the fact that they have very few teachers who are fluent in Kenyan sign language. In order to meet the needs of schools and to provide employment opportunities for Deaf Kenyan adults, a small non-governmental organisation identified Deaf secondary school students for training. They received two years of teacher training free of charge. Most have since been awarded teaching contracts by the Kenyan Teacher Service Commission or local school boards. This article reports on results from a preliminary study of the social and academic impacts of this innovation. Results indicate that Deaf teachers are inspirational in the classroom, represent a significant resource for their school communities and are preferred by Deaf students. A follow-up study on the relative learning gains of Deaf students when taught by Deaf teachers is planned once relevant data are available.

2013-01-01

Sleep disorders may affect the health and normal life of human badly. However, the pathophysiology underlying adult sleep disorders is still unclear. Functional neuroimaging can be used to investigate whether sleep disorders are associated with specific changes in brain structure or regional activity. This paper reviews functional brain imaging findings in major intrinsic sleep disorders (i.e., idiopathic insomnia, narcolepsy, and obstructive sleep apnea) and in abnormal motor behavior during sleep (i.e., periodic limb movement disorder and REM sleep behavior disorder). Metabolic/functional investigations (positron emission tomography, single photon emission computed tomography, functional magnetic resonance imaging) are mainly reviewed, as well as neuroanatomical assessments (voxel-based morphometry, magnetic resonance spectroscopy). Meanwhile, here are some brief introduction of different kinds of sleep disorders. (authors)

Ethical Issues in Conducting Research With Deaf Populations

Science.gov (United States)

Schlehofer, Deirdre; Thew, Denise

2013-01-01

Deaf American Sign Language (ASL) users represent a small population at risk for marginalization from research and surveillance activities resulting from cultural, language, and ethical challenges. The Deaf community’s view of deafness as a cultural identity, rather than a disability, contradicts the medical community’s perception of deafness as a disease or deficiency in need of correction or elimination. These differences continue to have significant cultural and social implications within the Deaf community, resulting in mistrust of research opportunities. Two particularly contentious ethical topics for the Deaf community are the absence of community representation in genetic research and the lack of accessible informed consents and research materials. This article outlines a series of innovative strategies and solutions to these issues, including the importance of community representation and collaboration with researchers studying deaf populations.

The role of music in deaf culture: deaf students' perception of emotion in music.

Science.gov (United States)

Darrow, Alice-Ann

2006-01-01

Although emotional interpretation of music is an individual and variable experience, researchers have found that typical listeners are quite consistent in associating basic or primary emotions such as happiness, sadness, fear, and anger to musical compositions. It has been suggested that an individual with a sensorineural hearing loss, or any lesion in auditory perceptors in the brain may have trouble perceiving music emotionally. The purpose of the present study was to investigate whether students with a hearing loss who associate with the deaf culture, assign the same emotions to music as students without a hearing loss. Sixty-two elementary and junior high students at a Midwestern state school for the deaf and students at neighboring elementary and junior high schools served as participants. Participants at the state school for the deaf had hearing losses ranging from moderate to severe. Twelve film score excerpts, composed to depict the primary emotions-happiness, sadness, and fear, were used as the musical stimuli. Participants were asked to assign an emotion to each excerpt. Results indicated a significant difference between the Deaf and typical hearing participants' responses, with hearing participants' responses more in agreement with the composers' intent. No significant differences were found for age or gender. Analyses of the Deaf participants' responses indicate that timbre, texture, and rhythm are perhaps the musical elements most influential in transmitting emotion to persons with a hearing loss. Adaptive strategies are suggested for assisting children who are deaf in accessing the elements of music intended to portray emotion.

Full Text Available Introduction: A deaf child creates a feeling of stigma in many hearing parents. Stigma in mothers can have a negative impact on a child’s treatment and rehabilitation process. Therefore, this study was conducted to evaluate the extent of stigma in mothers with deaf children.  Materials and Methods: This descriptive, cross-sectional study was conducted in 2013 among 90 mothers with deaf children. The data-collection instrument included the stigma scale in the mothers of children with disabilities. The reliability and validity of the instrument were confirmed through content validity and Cronbach’s alpha coefficient (α=86%, respectively. Data were analyzed using SPSS-15 software.   Results: Results showed that most mothers suffer from stigma due to having a deaf child. The mean stigma score was 96.48 ±27.72. In total, 24.4% of mothers reported that they had received strange and mocking looks; 72.2% regarded child deafness as a sign of divine retribution; and 33.3% felt ashamed of their child’s deafness. There was an inverse relationship between the mother’s level of education and mean stigma scores (P

An analysis of the inheritance pattern of an adult-onset hearing loss in Border Collie dogs.

Schmutz, Sheila M

2014-01-01

During routine diagnostic BAER testing of dogs of various breeds for private owners at the Western College of Veterinary Medicine in Saskatoon, it became evident that some individual dogs developed hearing loss as adults. Although inherited congenital deafness has been widely reported in dogs, this type of deafness had not. Special clinics were set up to screen working Border Collies at herding competitions. To determine the typical age that geriatric deafness might be expected, retired dogs were also recruited. Five of the 10 Border Collies 12 years of age or older had hearing loss (1 bilaterally deaf and 4 had reduced hearing). The adult onset deafness which exhibited in three families, did not usually occur until 5 years of age, too young to be geriatric deafness. This adult onset deafness fits an autosomal dominant pattern of inheritance. Several of these dogs had been BAER tested at younger ages with no sign of deafness. The deaf dogs were not associated with either gender. A survey was developed which was completed by the dog owners, that indicated that the hearing loss was gradual, not sudden. In addition, some family studies were conducted. Dogs at 5 years of age were often in the prime of their herding careers and then did not respond appropriately to distant commands. This type of deafness is important to dog owners but is also a potential medical model for some forms of hearing loss in humans. This report also suggests that geriatric hearing loss is common in dogs older than 12 years.

Neuroimaging Endophenotypes in Autism Spectrum Disorder

Mahajan, Rajneesh; Mostofsky, Stewart H.

2015-01-01

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that has a strong genetic basis, and is heterogeneous in its etiopathogenesis and clinical presentation. Neuroimaging studies, in concert with neuropathological and clinical research, have been instrumental in delineating trajectories of development in children with ASD. Structural neuroimaging has revealed ASD to be a disorder with general and regional brain enlargement, especially in the frontotemporal cortices, while functional neuroimaging studies have highlighted diminished connectivity, especially between frontal-posterior regions. The diverse and specific neuroimaging findings may represent potential neuroendophenotypes, and may offer opportunities to further understand the etiopathogenesis of ASD, predict treatment response and lead to the development of new therapies.

Pfeifer, Jennifer H; Peake, Shannon J

2012-01-01

This review integrates cognitive, socioemotional, and neuroimaging perspectives on self-development. Neural correlates of key processes implicated in personal and social identity are reported from studies of children, adolescents, and adults, including autobiographical memory, direct and reflected self-appraisals, and social exclusion. While cortical midline structures of medial prefrontal cortex and medial posterior parietal cortex are consistently identified in neuroimaging studies considering personal identity from a primarily cognitive perspective ("who am I?"), additional regions are implicated by studies considering personal and social identity from a more socioemotional perspective ("what do others think about me, where do I fit in?"), especially in child or adolescent samples. The involvement of these additional regions (including tempo-parietal junction and posterior superior temporal sulcus, temporal poles, anterior insula, ventral striatum, anterior cingulate cortex, middle cingulate cortex, and ventrolateral prefrontal cortex) suggests mentalizing, emotion, and emotion regulation are central to self-development. In addition, these regions appear to function atypically during personal and social identity tasks in autism and depression, exhibiting a broad pattern of hypoactivation and hyperactivation, respectively.

In total, 24.4% of mothers reported that they had received strange and mocking looks; 72.2% regarded child deafness as a sign of divine retribution; and 33.3% felt ashamed of their child's deafness. There was an inverse relationship between the mother's level of education and mean stigma scores (P<0.033). The stigma score was higher in mothers who were living independently of their relatives (P<0.029). The mean stigma score in mothers of children with a cochlear implant was lower than that of mothers of children with earphones (86.70 vs. 99.64), and this difference tended towards significance (P=0.057). This study showed that half of all mothers with deaf children were scorned and felt ashamed of having a deaf child in the family because of the stigma. The majority of mothers with deaf children felt stigmatized, and only their education and residency status affected this issue. The mothers of cochlear-implanted children perceived less stigma. Due to the various social and psychological problems caused by hearing impairment, it is necessary to consider the emotional health and psychological state of the mothers in addition to rehabilitation programs and standard services for the children themselves.

2006-01-01

Waardenburg Syndrome (WS) is an autosomal, dominantly inherited disorder that accounts for more than 2% cases of congenital deafness. The aim of this study is to determine the WS incidence among deaf pupils. Dysmorphological examination was performed on 720 children who were attending 7 special schools in Turkey and who had hearing disabilities. All subjects in the study were examined for WS diagnostic criteria. We detected 49 patients (6.8%) with WS among the 720 children examined. Six patients had WS type 1 (12.2%) and 43 had type 2 (87.8%). We observed 2 to 5 major diagnostic criteria for WS. Out of all the subjects in the study, only two patients have deaf first degree relatives. All subjects had been previously examined by physicians for deafness but none of them had been then diagnosed to have Waardenburg Syndrome. Instead, they were all misdiagnosed as to have nonsyndromic deafness. Awareness of WS diagnostic criteria by the physicans will provide accurate diagnosis for many deaf pupils and their first degree relatives who are able-to-hear WS patients and whose children are at risk for deafness.

Visual attention and the neuroimage bias.

Directory of Open Access Journals (Sweden)

D A Baker

Full Text Available Several highly-cited experiments have presented evidence suggesting that neuroimages may unduly bias laypeople's judgments of scientific research. This finding has been especially worrisome to the legal community in which neuroimage techniques may be used to produce evidence of a person's mental state. However, a more recent body of work that has looked directly at the independent impact of neuroimages on layperson decision-making (both in legal and more general arenas, and has failed to find evidence of bias. To help resolve these conflicting findings, this research uses eye tracking technology to provide a measure of attention to different visual representations of neuroscientific data. Finding an effect of neuroimages on the distribution of attention would provide a potential mechanism for the influence of neuroimages on higher-level decisions. In the present experiment, a sample of laypeople viewed a vignette that briefly described a court case in which the defendant's actions might have been explained by a neurological defect. Accompanying these vignettes was either an MRI image of the defendant's brain, or a bar graph depicting levels of brain activity-two competing visualizations that have been the focus of much of the previous research on the neuroimage bias. We found that, while laypeople differentially attended to neuroimagery relative to the bar graph, this did not translate into differential judgments in a way that would support the idea of a neuroimage bias.

Epistemologies, deafness, learning, and teaching.

Science.gov (United States)

Moores, Donald F

2010-01-01

The study of Deaf epistemologies is in a nascent stage relative to, e.g., the study of feminist or African American epistemologies. It has only recently begun attracting the widespread attention it deserves. The present article addresses Deaf epistemologies as they relate to the sometimes conflicting trends in American society and education. In a relatively short period, the education of deaf students has gone from an independent enterprise under the aegis of special education to heavy influence by No Child Left Behind legislation that applies to virtually all American students. American education at one and the same time embraces and celebrates diversity, imposes uniform, rigid learning standards for all children, and mandates that all children be tested in the same way. An oxymoron exists of individualized educational planning and one-size-fits-all curricula and assessment of academic achievement. Implications for teaching and learning of deaf students are explored.

Progress in identifying genes for deafness together with implementation of universal audiologic screening of newborns has provided the opportunity for more widespread use of molecular tests to detect genetic forms of hearing loss. Efforts to assess consumer attitudes toward these advances have lagged behind. Consumer focus groups were held to explore attitudes toward genetic advances and technologies for hearing loss, views about newborn hearing screening, and reactions to the idea of adding molecular screening for hearing loss at birth. Focus group discussions were recorded, transcribed and analyzed. Five focus groups with 44 participants including hearing parents of deaf children, deaf parents and young deaf adults were held. Focus group participants supported the use of genetic tests to identify the etiology of hearing loss but were concerned that genetic information might influence reproductive decisions. Molecular newborn screening was advocated by some; however, others expressed concern about its effectiveness. Documenting the attitudes of parents and other consumers toward genetic technologies establishes the framework for discussions on the appropriateness of molecular newborn screening for hearing loss and informs specialists about potential areas of public education necessary prior to the implementation of such screening.

2013-02-01

Full Text Available Bilingualism of a deaf child implies concurrent cognition and usage of sign language, as community language and oral-voice language as language of greater community in which deaf persons live. Today, most authors consider that deaf persons should know both of these languages and that deaf persons need to be educated in both languages, because of their general communication and complete psycho-social development. Through research on sample of 80 deaf examinees, we affirmed the kind of relation that deaf persons have towards bilingualism, bilingual way of education and communication. The research results have shown that bilingualism and bilingual way of education and communication is acceptable to deaf persons and that there is no statistically significant difference between the sub-samples of examinees.

Lanari, M; Capretti, M G; Lazzarotto, T; Gabrielli, L; Rizzollo, S; Mostert, M; Manzoni, P

2012-05-01

Neonatal congenital infections are an important cause of mortality, morbidity and long-term neurodevelopmental and sensorineural sequelae. Many pathogens can cause in utero infection, and among them, cytomegalovirus (CMV) plays a prominent role. In developed countries, CMV poses major health problems as it is the most common pathogen leading to congenital infection, and the leading cause of nonhereditary deafness in children. Evaluation of central nervous system (CNS) involvement in congenital CMV infected newborns is mandatory to better assess the severity of the disease, to guide adequate treatment, to define prognosis, and to tailor follow-up observations and parents' counselling. Cerebral ultrasonography (cUS), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI) are the currently available techniques to evaluate infants with suspected or proven congenital CMV infection. In congenital CMV infection, their role in early detection and confirmation of cerebral involvement within the first month of life is crucial to initiate specific treatment with antivirals. Neonatologists, paediatricians and radiologists should be aware of the role, the limitations and the inherent risks related to the use of these specific neuroimaging diagnostic tools in these infants. In this article we will discuss from a neonatological perspective the advantages, disadvantages, risks and limitations of each imaging technique. Copyright © 2012 Elsevier Ireland Ltd.

Mitchell, Teresa V.; Letourneau, Susan M.; Maslin, Melissa T.

2013-01-01

Purpose This study examined the effects of deafness and sign language use on the distribution of attention across the top and bottom halves of faces. Methods In a composite face task, congenitally deaf signers and typically hearing controls made same/different judgments of the top or bottom halves of faces presented with the halves aligned or spatially misaligned, while event-related potentials (ERPs) were recorded. Results Both groups were more accurate when judging misaligned than aligned faces, which indicates holistic face processing. Misalignment affected all ERP components examined, with effects on the N170 resembling those of face inversion. Hearing adults were similarly accurate when judging the top and bottom halves of the faces, but deaf signers were more accurate when attending to the bottom than the top. Attending to the top elicited faster P1 and N170 latencies for both groups; within the deaf group, this effect was greatest for individuals who produced the highest accuracies when attending to the top. Conclusions These findings dovetail with previous research by providing behavioral and neural evidence of increased attention to the bottom half of the face in deaf signers, and by documenting that these effects generalize to a speeded task, in the absence of gaze shifts, with neutral facial expressions.

Deaf American Sign Language (ASL) users comprise a linguistic minority population with poor health care access due to communication barriers and low health literacy. Potentially, these health care barriers could increase Emergency Department (ED) use. To compare ED use between deaf and non-deaf patients. A retrospective cohort from medical records. The sample was derived from 400 randomly selected charts (200 deaf ASL users and 200 hearing English speakers) from an outpatient primary care health center with a high volume of deaf patients. Abstracted data included patient demographics, insurance, health behavior, and ED use in the past 36 months. Deaf patients were more likely to be never smokers and be insured through Medicaid. In an adjusted analysis, deaf individuals were significantly more likely to use the ED (odds ratio [OR], 1.97; 95% confidence interval [CI], 1.11-3.51) over the prior 36 months. Deaf American Sign Language users appear to be at greater odds for elevated ED utilization when compared to the general hearing population. Efforts to further understand the drivers for increased ED utilization among deaf ASL users are much needed. Copyright © 2015 Elsevier Inc. All rights reserved.

Kuenburg, Alexa; Fellinger, Paul; Fellinger, Johannes

2016-01-01

Access to health care without barriers is a clearly defined right of people with disabilities as stated by the UN Convention on the Rights of People with Disabilities. The present study reviews literature from 2000 to 2015 on access to health care for deaf people and reveals significant challenges in communication with health providers and gaps in global health knowledge for deaf people including those with even higher risk of marginalization. Examples of approaches to improve access to health care, such as providing powerful and visually accessible communication through the use of sign language, the implementation of important communication technologies, and cultural awareness trainings for health professionals are discussed. Programs that raise health knowledge in Deaf communities and models of primary health care centers for deaf people are also presented. Published documents can empower deaf people to realize their right to enjoy the highest attainable standard of health. © The Author 2015. Published by Oxford University Press. All rights reserved.

Representations of deaf characters in children's picture books.

Science.gov (United States)

Golos, Debbie B; Moses, Annie M

2011-01-01

Picture books can influence how children perceive people of different backgrounds, including people with disabilities whose cultures differ from their own. Researchers have examined the portrayal of multicultural characters with disabilities in children's literature. However, few have specifically considered the portrayal of deaf characters, despite increased inclusion of deaf characters in children's literature over the past two decades. The present study analyzed the portrayal of deaf characters in picture books for children ages 4-8 years. A content analysis of 20 children's picture books was conducted in which the books were analyzed for messages linked to pathological and cultural categories. Results indicated that these books did not portray Deaf characters from a cultural perspective but, rather, highlighted aspects of deafness as a medical condition, one that requires fixing and that perpetuates stereotypes of deafness as a disability.

The cochleovestibular tract is seldom involved by sarcoidosis (about 50 cases have been described since 1948). As a clinical expression of sarcoidosis, deafness is fluctuant in 50% of all cases, bilateral, and most often associated with facial palsy and uveitis, the vestibular reflexes being reduced. The histological studies demonstrate lesions at all levels from the cochlea to be brain stem, but the main mechanism is an infiltration of the arachnoid vessels. The prognosis of sarcoidosis deafness is usually poor in spite of corticosteroid therapy. This paper is illustrated by 3 cases observed in Avicenne Hospital.

Beethoven's deafness, the defiance of a genius

Directory of Open Access Journals (Sweden)

Bento, Ricardo Ferreira

2009-09-01

Full Text Available Introduction: Ludwig van Beethoven, one of the greatest composers in History, was tormented for his whole life by a progressive deafness without definitive diagnosis. Many authors published studies about the etiologic possibilities of the deafness of the music genius with different explanations about his auditory loss. In this work, the author discusses the implications of Beethoven's progressive deafness to the creation of his word, as well as etiologic assumptions of his disease. Would Beethoven have had the same ingeniousness he showed in his symphonies if he did not have hypacusis and tinnitus? What is the influence of his deafness on his work and life? Could he have had a more precise diagnosis and specially a treatment nowadays? Would we have the brilliant composer if he had deafness today? We surely could not have!

The Hear and See methodology has often been used as a means of enhancing pedagogy by focusing on the two strongest learning senses, but this naturally does not apply to deaf or hard of hearing students. Because deaf students' prior nonaural experiences with sound will vary significantly from those of students with typical hearing, different methods must be used to build understanding. However, the sensory-focused pedagogical principle can be applied in a different way for the Deaf by utilizing the senses of touch and sight, called here the ``See and Feel'' method. This presentation will provide several examples of how acoustics demonstrations have been adapted to create an outreach program for a group of junior high students from a school for the Deaf and discuss challenges encountered.

The etiology of perceptive deafness, especially the congenital variety, requires investigation. The presence of a variety of signs associated with deafness constitutes an "associated syndrome" and helps to define a possible genetic origin. These syndromes only represent a small percentage of overall causes of deafness in children, since at most they account for only 10% of cases. Certain syndromes are encountered more often or are well known, others are extremely rare or have only been described recently. The authors report six of these very rare syndromes discovered among their patients: a KID syndrome, a Leopard syndrome, a Norrie syndrome, a Jervell and Lange Nielsen syndrome, a recently described entity called CEE with deafness and an External Neuro-Cochleo-Pancreatic syndrome which would not appear to have been previously described.

Every so often there are stories that take the world by storm and make such an impact that they become part of our everyday world. These stories, characters, and themes become established elements of cultural literacy. This is exactly what has happened with J. K. Rowling's Harry Potter series. Harry and his cohort of wizards, witches, and their adventures have become an indispensable part of popular literature and popular culture. We have developed an innovative way to ensure that Deaf children, their families, and anyone studying literature (Deaf or general) gain a deeper understanding of this phenomenon. In fact, we go further by demonstrating how using a Deaf Lens provides the greatest insight into the fascinating world of Harry Potter. Utilizing a Deaf Studies Template and a Deaf Lens, we capitalize on the experiences of Deaf people everywhere while celebrating the valuable role American Sign Language has in academic programming.

Retrospective Basic Parent-Child Communication Difficulties and Risk of Depression in Deaf Adults.

Science.gov (United States)

Kushalnagar, Poorna; Bruce, Sheila; Sutton, Tina; Leigh, Irene W

2017-02-01

This paper describes the relationship between retrospective communication difficulties and current depressive symptomatology. A total of 143 deaf/hard-of-hearing late adolescents and adults (64 % White; 55 % female) completed questionnaires related to parent communication, language history and current psychological functioning. Logistic regression models were used to estimate the likelihood of having depression that is associated with understanding parents' communication after controlling for gender, hearing level, and language history. Significant odds ratio indicated that the difficulties in understanding basic communication with parents increased the odds of depression symptomatology. The odds ratio indicates that when holding all other variables constant, the odds of reporting depression were at least 8 times higher for those who reported being able to understand some to none of what the same-sex parent said. For the different-gender parent, only the mother's communication with the male individual was associated with depression. Although our study findings suggest that DHH men and women with history of communication difficulties at home are at risk for depression in adulthood, they do not provide information on the causal mechanisms linking communication difficulties early in life and depression later in life. Greater attention should be given to promoting healthy communication between DHH girls and their mothers as well as DHH boys and their fathers, which might reduce the impact on later emergence of depression in the DHH individual.

Phonological processing of rhyme in spoken language and location in sign language by deaf and hearing participants: a neurophysiological study.

Science.gov (United States)

Colin, C; Zuinen, T; Bayard, C; Leybaert, J

2013-06-01

Sign languages (SL), like oral languages (OL), organize elementary, meaningless units into meaningful semantic units. Our aim was to compare, at behavioral and neurophysiological levels, the processing of the location parameter in French Belgian SL to that of the rhyme in oral French. Ten hearing and 10 profoundly deaf adults performed a rhyme judgment task in OL and a similarity judgment on location in SL. Stimuli were pairs of pictures. As regards OL, deaf subjects' performances, although above chance level, were significantly lower than that of hearing subjects, suggesting that a metaphonological analysis is possible for deaf people but rests on phonological representations that are less precise than in hearing people. As regards SL, deaf subjects scores indicated that a metaphonological judgment may be performed on location. The contingent negative variation (CNV) evoked by the first picture of a pair was similar in hearing subjects in OL and in deaf subjects in OL and SL. However, an N400 evoked by the second picture of the non-rhyming pairs was evidenced only in hearing subjects in OL. The absence of N400 in deaf subjects may be interpreted as the failure to associate two words according to their rhyme in OL or to their location in SL. Although deaf participants can perform metaphonological judgments in OL, they differ from hearing participants both behaviorally and in ERP. Judgment of location in SL is possible for deaf signers, but, contrary to rhyme judgment in hearing participants, does not elicit any N400. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

The Educational Workshops Importance of Students in Teaching-learning Deaf

Full Text Available Inclusive educational workshops can be used as teaching strategies for deaf students to integrate into society, allowing who are beneficiaries of diversified teaching methods, encouraging them to become active citizens in their rights and duties according to their potential. In order to build knowledge collectively, inclusive educational workshops were developed as the project methodology "The Natural Science Museum Goes to School: a proposal for inclusive education", which aimed to raise awareness among deaf students of the School of Special Education Helen Keller Caxias do Sul / RS on the importance of environmental preservation. The workshops allowed autonomy in the construction of knowledge as related theory with practice, creating situations where students stopped being only learning receivers. Workshops were held as hanging garden, environmental commitment, sensory garden, animals in origami, green puppet, puppet fish and terrarium. Participated in these activities students from 1st to 9th grades of elementary school and adult education, covering 102 participants. During the workshops inquiries were carried out, encouraging students to share prior knowledge with colleagues and enabling these acquire new environmental information, making meaningful learning. Pedagogical workshops should be used as support tools in the classroom, and worked in continuous and interdisciplinary way. As a result, deaf students feel valued and producers of their knowledge and will experience different activities recognizing the importance of learning to their daily lives.

Widespread auditory deficits in tune deafness.

Jones, Jennifer L; Zalewski, Christopher; Brewer, Carmen; Lucker, Jay; Drayna, Dennis

2009-02-01

The goal of this study was to investigate auditory function in individuals with deficits in musical pitch perception. We hypothesized that such individuals have deficits in nonspeech areas of auditory processing. We screened 865 randomly selected individuals to identify those who scored poorly on the Distorted Tunes test (DTT), a measure of musical pitch recognition ability. Those who scored poorly were given a comprehensive audiologic examination, and those with hearing loss or other confounding audiologic factors were excluded from further testing. Thirty-five individuals with tune deafness constituted the experimental group. Thirty-four individuals with normal hearing and normal DTT scores, matched for age, gender, handedness, and education, and without overt or reported psychiatric disorders made up the normal control group. Individual and group performance for pure-tone frequency discrimination at 1000 Hz was determined by measuring the difference limen for frequency (DLF). Auditory processing abilities were assessed using tests of pitch pattern recognition, duration pattern recognition, and auditory gap detection. In addition, we evaluated both attention and short- and long-term memory as variables that might influence performance on our experimental measures. Differences between groups were evaluated statistically using Wilcoxon nonparametric tests and t-tests as appropriate. The DLF at 1000 Hz in the group with tune deafness was significantly larger than that of the normal control group. However, approximately one-third of participants with tune deafness had DLFs within the range of performance observed in the control group. Many individuals with tune deafness also displayed a high degree of variability in their intertrial frequency discrimination performance that could not be explained by deficits in memory or attention. Pitch and duration pattern discrimination and auditory gap-detection ability were significantly poorer in the group with tune deafness

Full Text Available Este artigo propõe-se discutir a temática da surdez, articulando-a com discussões referentes a gênero e sexualidade, tomando por referência autores da perspectiva dosEstudos Culturais em Educação e dos Estudos Surdos. A surdez e os surdos, assim como o gênero, são entendidos a partir da diferença cultural. No mercado de trabalho em geral, as surdas são discriminadas, porém são a maioria no professorado, o que é uma conseqüência da feminização do trabalho docente. A crescente presença feminina na liderança dos movimentos surdos pode estar relacionada a essa maioria de professoras, que carregam para os movimentos características da organização escolar. Analisamos dois artigos sobre o tema, além de um encontro sobre mulheres surdas ocorrido em Pelotas – RS, onde as participantes destacaram seu papel na luta política da associação dos surdos, enquanto aos homens cabe o papel de organizar as atividades de lazer e esportes. A luta pelos direitos das mulheres surdas vem crescendo no Brasil e há necessidade de haver mais estudos sobre essa temática.Abstract This paper discusses the topic of deafness, articulating it with discussions referring to gender and sexuality, based on authors from the perspectives of Cultural Studies in Education and Deaf Studies. Deafness and deaf people, as the gender issue, are understood through a cultural difference perspective.

2014-12-01

This article ethnographically examines how some deaf people in urban India have begun to orient themselves toward the future by participating in multilevel marketing businesses. In the absence of other structural possibilities for deaf future-making, deaf Indians have turned to such businesses in search of social, economic, and moral livelihood. This article analyzes participation in one particular business and asks how participating within the business both enables and disables the cultivation of specific ideas of development. Particular attention is devoted to exploring the multiple registers of the concept of "deaf development" and how such development may be cultivated through multilevel marketing businesses. This article aims to make a critical intervention in medical anthropology studies of disability by arguing that disability (or in this case deafness) can function as a source of value, therefore highlighting tensions between stigma and value. © 2014 by the American Anthropological Association.

Background Little is known about the sexual health behaviors of Deaf American Sign Language (ASL) users. Objective We sought to characterize the self-reported sexual behaviors of Deaf individuals. Methods Responses from 282 Deaf participants aged 18–64 from the greater Rochester, NY area who participated in the 2008 Deaf Health were analyzed. These data were compared with weighted data from a general population comparison group (N=1890). We looked at four sexual health-related outcomes: abstinence within the past year; number of sexual partners within the last year; condom use at last intercourse; and ever tested for HIV. We performed descriptive analyses, including stratification by gender, age, income, marital status, and educational level. Results Deaf respondents were more likely than the general population respondents to self-report two or more sexual partners in the past year (30.9% vs 10.1%) but self-reported higher condom use at last intercourse (28.0% vs 19.8%). HIV testing rates were similar between groups (47.5% vs 49.4%) but lower for certain Deaf groups: Deaf women (46.0% vs. 58.1%), lower-income Deaf (44.4% vs. 69.7%) and among less educated Deaf (31.3% vs. 57.7%) than among respondents from corresponding general population groups. Conclusion Deaf respondents self-reported higher numbers of sexual partners over the past year compared to the general population. Condom use was higher among Deaf participants. HIV was similar between groups, though HIV testing was significantly lower among lower-income, less well-educated, and female Deaf respondents. Deaf individuals have a sexual health risk profile that is distinct from that of the general population. PMID:26242551

Little is known about the sexual health behaviors of Deaf American Sign Language (ASL) users. We sought to characterize the self-reported sexual behaviors of Deaf individuals. Responses from 282 Deaf participants aged 18-64 from the greater Rochester, NY area who participated in the 2008 Deaf Health were analyzed. These data were compared with weighted data from a general population comparison group (N = 1890). We looked at four sexual health-related outcomes: abstinence within the past year; number of sexual partners within the last year; condom use at last intercourse; and ever tested for HIV. We performed descriptive analyses, including stratification by gender, age, income, marital status, and educational level. Deaf respondents were more likely than the general population respondents to self-report two or more sexual partners in the past year (30.9% vs 10.1%) but self-reported higher condom use at last intercourse (28.0% vs 19.8%). HIV testing rates were similar between groups (47.5% vs 49.4%) but lower for certain Deaf groups: Deaf women (46.0% vs 58.1%), lower-income Deaf (44.4% vs 69.7%) and among less educated Deaf (31.3% vs 57.7%) than among respondents from corresponding general population groups.

Strain George M

2007-11-01

Full Text Available Abstract Background The association between patterns of pigmentation and deafness in the dog has a long-documented history, with reports dating back over one hundred years. Long suspected of having a genetic basis, the search for loci with a pronounced influence in the expression of hearing loss in the dog has yet to be successful. No studies in the dog to date have found a possible influence of a specific colour locus associated with deafness. The present study is intended to evaluate the heritability of deafness in the Jack Russell Terrier (JRT, characterize the mode of inheritance, and evaluate the existence of a sex, coat colour, or coat texture influence on the expression of sensorineural deafness. Results The estimation of heritability of deafness in the JRT was 0.22 when deafness was considered a binary (normal/deaf trait and 0.31 when deafness was considered a three-category (normal/unilateral/bilateral deafness. The influence of coat colour in the incidence of JRT deafness was statistically significant, indicating that dogs with more white are more likely to be deaf. The influence of sex or coat texture was not statistically significant in the incidence of JRT deafness. Complex segregation analysis revealed a model of a single locus with a large effect on the binary measure of hearing loss is not supported. Conclusion This is the first attempt, to our knowledge, to characterize a genetic component responsible for deafness in the JRT. The heritability of deafness in the JRT was found to be 0.22 and 0.31 considering deafness to be a two-category or three-category trait, respectively. There appears to be an influence of coat colour on the expression of deafness. In an attempt to characterize the mode of inheritance of deafness in the JRT, a model of a single locus with a large effect on hearing loss is not supported with this data. Further study is needed to determine if a single locus may be influencing deafness in the JRT. While the

Neuroimaging in psychiatry: from bench to bedside

Directory of Open Access Journals (Sweden)

David E Linden

2009-12-01

Full Text Available This perspective considers the present and the future role of different neuroimaging techniques in the field of psychiatry. After identifying shortcomings of the mainly symptom-focussed diagnostic processes and treatment decisions in modern psychiatry, we suggest topics where neuroimaging methods have the potential to help. These include better understanding of the pathophysiology, improved diagnoses, assistance in therapeutic decisions and the supervision of treatment success by direct assessment of improvement in disease-related brain functions. These different questions are illustrated by examples from neuroimaging studies, with a focus on severe mental and neuropsychiatric illnesses such as schizophrenia, depression and dementia. Despite all reservations addressed in the article, we are optimistic, that neuroimaging has a huge potential with regard to the above-mentioned questions. We expect that neuroimaging will play an increasing role in the future refinement of the diagnostic process and aid in the development of new therapies in the field of psychiatry.

2015-09-01

The goal in this review was to summarize the results of clinical neuroimaging studies performed in patients with sports-related concussion (SRC) who were referred to a multidisciplinar ypediatric concussion program. The authors conducted a retrospective review of medical records and neuroimaging findings for all patients referred to a multidisciplinary pediatric concussion program between September 2013 and July 2014. Inclusion criteria were as follows: 1) age ≤ 19 years; and 2) physician-diagnosed SRC. All patients underwent evaluation and follow-up by the same neurosurgeon. The 2 outcomes examined in this review were the frequency of neuroimaging studies performed in this population (including CT and MRI) and the findings of those studies. Clinical indications for neuroimaging and the impact of neuroimaging findings on clinical decision making were summarized where available. This investigation was approved by the local institutional ethics review board. A total of 151 patients (mean age 14 years, 59% female) were included this study. Overall, 36 patients (24%) underwent neuroimaging studies, the results of which were normal in 78% of cases. Sixteen percent of patients underwent CT imaging; results were normal in 79% of cases. Abnormal CT findings included the following: arachnoid cyst (1 patient), skull fracture (2 patients), suspected intracranial hemorrhage (1 patient), and suspected hemorrhage into an arachnoid cyst (1 patient). Eleven percent of patients underwent MRI; results were normal in 75% of cases. Abnormal MRI findings included the following: intraparenchymal hemorrhage and sylvian fissure arachnoid cyst (1 patient); nonhemorrhagic contusion (1 patient); demyelinating disease (1 patient); and posterior fossa arachnoid cyst, cerebellar volume loss, and nonspecific white matter changes (1 patient). Results of clinical neuroimaging studies are normal in the majority of pediatric patients with SRC. However, in selected cases neuroimaging can provide

Full Text Available Maternally inherited diabetes and deafness (MIDD, which is caused by an A to G substitution at position 3243 (m.3243A>G in the transfer ribonucleic acid leucine gene, is characterized by diabetes and hearing loss. Patients with MIDD frequently have renal disease, which may precede the diagnosis of either diabetes or deafness or may be the sole manifestation of the m.3243A>G mutation. Recently, progressive renal failure was reported in adults, and a number of childhood cases of focal segmental glomerulosclerosis (FSGS of MIDD have been reported. However, little is known about the glomerular lesions in FSGS in MIDD. In the present study, we reported two cases of FSGS associated with MIDD and studied the clinical features of the proband and her mother.

Near-infrared neuroimaging with NinPy

Directory of Open Access Journals (Sweden)

Gary E Strangman

2009-05-01

Full Text Available There has been substantial recent growth in the use of non-invasive optical brain imaging in studies of human brain function in health and disease. Near-infrared neuroimaging (NIN is one of the most promising of these techniques and, although NIN hardware continues to evolve at a rapid pace, software tools supporting optical data acquisition, image processing, statistical modeling and visualization remain less refined. Python, a modular and computationally efficient development language, can support functional neuroimaging studies of diverse design and implementation. In particular, Python's easily readable syntax and modular architecture allow swift prototyping followed by efficient transition to stable production systems. As an introduction to our ongoing efforts to develop Python software tools for structural and functional neuroimaging, we discuss: (i the role of noninvasive diffuse optical imaging in measuring brain function, (ii the key computational requirements to support NIN experiments, (iii our collection of software tools to support near-infrared neuroimaging, called NinPy, and (iv future extensions of these tools that will allow integration of optical with other structural and functional neuroimaging data sources.

Deaf murderers: clinical and forensic issues.

Science.gov (United States)

Vernon, M; Steinberg, A G; Montoya, L A

1999-01-01

Data are reported on 28 deaf individuals who were convicted, pled guilty, or have been charged and awaiting trial for murder. The unique forensic issues raised by these cases are discussed, and their clinical picture presented. A significant percentage of these deaf murderers and defendants had such severely limited communication skills in both English and American Sign Language that they lacked the linguistic ability to understand the charges against them and/or to participate in their own defense. As such, they were incompetent to stand trial, due not to mental illness or mental retardation, but to linguistic deficits. This form of incompetence poses a dilemma to the courts that remains unresolved. This same linguistic disability makes it impossible for some deaf suspects to be administered Miranda Warnings in a way comprehensible to them. This paper identifies the reasons for the communication problems many deaf persons face in court and offers remedial steps to help assure fair trials and police interrogations for deaf defendants. The roles and responsibilities of psychiatric and psychological experts in these cases are discussed. Data are provided on the etiology of the 28 individuals' hearing losses, psychiatric/psychological histories, IQs, communication characteristics, educational levels, and victim characteristics.

Visual perceptual load induces inattentional deafness.

Science.gov (United States)

Macdonald, James S P; Lavie, Nilli

2011-08-01

In this article, we establish a new phenomenon of "inattentional deafness" and highlight the level of load on visual attention as a critical determinant of this phenomenon. In three experiments, we modified an inattentional blindness paradigm to assess inattentional deafness. Participants made either a low- or high-load visual discrimination concerning a cross shape (respectively, a discrimination of line color or of line length with a subtle length difference). A brief pure tone was presented simultaneously with the visual task display on a final trial. Failures to notice the presence of this tone (i.e., inattentional deafness) reached a rate of 79% in the high-visual-load condition, significantly more than in the low-load condition. These findings establish the phenomenon of inattentional deafness under visual load, thereby extending the load theory of attention (e.g., Lavie, Journal of Experimental Psychology. Human Perception and Performance, 25, 596-616, 1995) to address the cross-modal effects of visual perceptual load.

Deaf identities in a multicultural setting: The Ugandan context

Often located far apart from each other, deaf and hearing impaired persons face a multiplicity of challenges that evolve around isolation, neglect and the deprivation of essential social services that affect their welfare and survival. Although it is evident that the number of persons born with or acquire hearing impairments in later stages of their lives is increasing in many developing countries, there is limited research on this population. The main objective of this article is to explore the identities and experiences of living as a person who is deaf in Uganda. Using data from semi-structured interviews with 42 deaf persons (aged 19–41) and three focus group discussions, the study findings show that beneath the more pragmatic identities documented in the United States and European discourses there is a matrix of ambiguous, often competing and manifold forms in Uganda that are not necessarily based on the deaf and deaf constructions. The results further show that the country's cultural, religious and ethnic diversity is more of a restraint than an enabler to the aspirations of the deaf community. The study concludes that researchers and policy makers need to be cognisant of the unique issues underlying deaf epistemologies whilst implementing policy and programme initiatives that directly affect them. The upper case ‘D’ in the term deaf is a convention that has been used since the early 1970s to connote a ‘socially constructed visual culture’ or a linguistic, social and cultural minority group who use sign language as primary means of communication and identify with the deaf community, whereas the lower case ‘d’ in deaf refers to ‘the audio logical condition of hearing impairment’. However, in this article the lower case has been used consistently. PMID:28730015

Full text: Neuroimaging methods are of great importance for the differential diagnostic delimitation of movement disorders associated with structural damage (neoplasms, ischemic lesions, neuroinfections) from those associated with specific pathophysiological mechanisms (dysmetabolic disorders, neurotransmitter disorders). Learning objective: Presentation of typical imaging findings contributing to nosological differentiation in groups of movement disorders with similar clinical signs. In this presentation are discussed neuroimaging findings in Parkinson‘s disease, atypical parkinsonian syndromes (multiple system atrophy, progressive supranuclear palsy, corticobasal degeneration), parkinsonism in genetically mediated diseases (Wilson’s disease, pantothenate kinase-associated neurodegeneration – PKAN), vascular parkinsonism, hyperkinetic movement disorders (palatal tremor, Huntington‘s chorea, symptomatic chorea in ischemic stroke and diabetes, rubral tremor, ballismus, hemifacial spasm).

Neuromarketing: the hope and hype of neuroimaging in business.

Science.gov (United States)

Ariely, Dan; Berns, Gregory S

2010-04-01

The application of neuroimaging methods to product marketing - neuromarketing - has recently gained considerable popularity. We propose that there are two main reasons for this trend. First, the possibility that neuroimaging will become cheaper and faster than other marketing methods; and second, the hope that neuroimaging will provide marketers with information that is not obtainable through conventional marketing methods. Although neuroimaging is unlikely to be cheaper than other tools in the near future, there is growing evidence that it may provide hidden information about the consumer experience. The most promising application of neuroimaging methods to marketing may come before a product is even released - when it is just an idea being developed.

Objectives : Neuroimaging is contributing to the rising costs of dizziness evaluation. This study examined the rate of central neurological causes of dizziness, relevant clinical predictors, and the costs and diagnostic yields of neuroimaging in dizziness assessment. Methods : We retrospectively reviewed the records of 521 adult patients who visited the hospital during a 12-month period with dizziness as the chief complaint. Clinical findings were analyzed using Fisher's exact test to determine how they correlated with central neurological causes of dizziness identified by neuroimaging. Costs and diagnostic yields of neuroimaging were calculated. Results : Of the 521 patients, 1.5% had dizziness produced by central neurological causes. Gait abnormalities, limb ataxia, diabetes mellitus, and the existence of multiple neurological findings predicted central causes. Cases were associated with gait abnormalities, limb ataxia, diabetes mellitus, and the existence of multiple neurological findings . Brain computed tomography (CT) and magnetic resonance imaging (MRI) were performed in 42% and 9.5% of the examined cases, respectively, with diagnostic yields of 3.6% and 12%, respectively. Nine cases of dizziness were diagnosed from 269 brain scans, costing $607 914. Conclusion : Clinical evaluation can predict the presence of central neurological causes of dizziness, whereas neuroimaging is a costly and low-yield approach. Guidelines are needed for physicians, regarding the appropriateness of ordering neuroimaging studies.

Understanding the perceptions of genetic testing by members of the deaf community may help in planning deafness genetics research, especially so in the context of strong adherence to cultural values as found among native Africans. Among Yorubas in Nigeria, deafness is perceived to be caused by some offensive actions of the mother during pregnancy, spiritual attack, and childhood infections. We studied attitudes towards, and acceptance of genetic testing by the deaf community in Nigeria. Structured questionnaires were administered to individuals sampled from the Vocational Training Centre for the Deaf, the religious Community, and government schools, among others. The main survey items elicited information about the community in which the deaf people participate, their awareness of genetic testing, whether or not they view genetic testing as acceptable, and their understanding of the purpose of genetic testing. There were 150 deaf participants (61.3 % males, 38.7 % females) with mean age of 26.7 years ±9.8. A majority of survey respondents indicated they relate only with other members of the deaf community (78 %) and reported believing genetic testing does more good than harm (79.3 %); 57 % expressed interest in genetic testing. Interest in genetic testing for deafness or in genetic testing in pregnancy was not related to whether respondents relate primarily to the deaf or to the hearing community. However, a significantly higher number of male respondents and respondents with low education reported interest in genetic testing.

Factors impacting participation of European elite deaf athletes in sport.

Kurková, Petra; Válková, Hana; Scheetz, Nanci

2011-03-01

This study examine 53 European elite deaf athletes for their family's hearing status, use of hearing aids, communication preference, education in integrated or segregated settings, family members' encouragement for participation in sports, coach preference (hearing or deaf), and conditions for competitive events with deaf or hearing athletes. These data were gathered through semi-structured interviews administered in the athlete's native language. Deaf athletes reported that when given the opportunity to compete with hearing athletes, it enhanced their opportunity for competition. Participating in sports with hearing athletes played an important role in the integration of deaf athletes into mainstream society. If adaptations to communication can be made in these integrated settings, the ability of deaf athletes to participate in such settings will increase.

Stuttering is a disorder that affects millions of people all over the world. Over the past two decades, there has been a great deal of interest in investigating the neural basis of the disorder. This systematic literature review is intended to provide a comprehensive summary of the neuroimaging literature on developmental stuttering. It is a resource for researchers to quickly and easily identify relevant studies for their areas of interest and enable them to determine the most appropriate methodology to utilize in their work. The review also highlights gaps in the literature in terms of methodology and areas of research. We conducted a systematic literature review on neuroimaging studies on developmental stuttering according to the PRISMA guidelines. We searched for articles in the pubmed database containing "stuttering" OR "stammering" AND either "MRI", "PET", "EEG", "MEG", "TMS"or "brain" that were published between 1995/​01/​01 and 2016/​01/​01. The search returned a total of 359 items with an additional 26 identified from a manual search. Of these, there were a total of 111 full text articles that met criteria for inclusion in the systematic literature review. We also discuss neuroimaging studies on developmental stuttering published throughout 2016. The discussion of the results is organized first by methodology and second by population (i.e., adults or children) and includes tables that contain all items returned by the search. There are widespread abnormalities in the structural architecture and functional organization of the brains of adults and children who stutter. These are evident not only in speech tasks, but also non-speech tasks. Future research should make greater use of functional neuroimaging and noninvasive brain stimulation, and employ structural methodologies that have greater sensitivity. Newly planned studies should also investigate sex differences, focus on augmenting treatment, examine moments of dysfluency and longitudinally or

Two groups of patients with hearing handicaps have been investigated with PET and F-18-2-FDG. Since these patients were unilaterally deaf or profoundly deaf with a cochlear implant installed, monaural stimulation was possible excluding any effects of bone conduction to the contralateral ear. White noise was used as acoustic stimulus in unilaterally deaf patients. The peripheral auditory nerve of cochlear implant patients was stimulated by electrical impulses which were encoded from music or a 4-tone mixture by an electronic speech processor. The non-music stimuli were chosen to avoid associative cortical reactions. In both groups response to the stimuli by increase of glucose consumption (LCMRglc) was found not only in the contralateral primary auditory cortex as expected from neuroanatomical knowledge, but also in the ipsilateral auditory cortex. Furthermore there was no correlation between the hemisphere showing increased LCMRglc and the side of stimulation or the type of stimulus. The similarity of results obtained in both groups by acoustical and electrical stimulation of the auditory nerve suggests that this kind of measurement might be a tool to predict or check the performance of a cochlear implant in a profoundly deaf patient. The finding of increased LCMRglc in the area of the normal auditory cortex in patients profoundly deaf since birth contradicts the hypothesis of degeneration of this cortical center in such patients.

Over the years we have struggled with the difficulty of giving a planetarium show to a deaf audience. This is especially true for a younger audience with limited reading abilities. You must illuminate the ASL signer which causes light splash onto the dome. You must slow the presentation down to allow for time to interpret and then point. A slower presentation can have an adverse impact on the learning of the hearing students if the presentation is made to a mixed audience. To address these issues, we are currently working on methods to improve deaf education in a planetarium environment. We will present an overview of the current project along with efforts to establish baselines comprehension levels for both deaf and hearing children. This work is partially funded by an NSF IIS-1124548 grant and funding from the Sorenson Foundation.

Deafness and motor abilities level

A Zwierzchowska

2008-09-01

Full Text Available The audition injury hinders some motor motions and the organised coordination at the higher level and may be a cause of disturbances and disorder in some motor abilities adoption. It was assumed that deafness including its aetiology and injury mechanism may significantly influence the motor development of human being. The study aimed in checking if the deafness, as a result of various unfavourable factors, determines the motor development of children and youngsters. Consequently the dependency between qualitative features i.e.: signed motor level and aetiology, audition injury mechanism and the deafness degree was examined. The mechanism and aetiology of hearing correlated with the motor abilities displayed statistically significant dependencies in few motor trials only. Revealed correlations regarded mostly the coordination trials excluding the flexibility one. Statistically significant dependencies between the audition diminution and the motor abilities level were not found.

Full Text Available Background. No consensus between guidelines exists regarding neuroimaging in first-episode psychosis. The purpose of this study is to assess anomalies found in structural neuroimaging exams (brain computed tomography (CT and magnetic resonance imaging (MRI in the initial medical work-up of patients presenting first-episode psychosis. Methods. The study subjects were 32 patients aged 18–48 years (mean age: 29.6 years, consecutively admitted with first-episode psychosis diagnosis. Socio-demographic and clinical data and neuroimaging exams (CT and MRI were retrospectively studied. Diagnostic assessments were made using the Operational Criteria Checklist +. Neuroimaging images (CT and MRI and respective reports were analysed by an experienced consultant psychiatrist. Results. None of the patients had abnormalities in neuroimaging exams responsible for psychotic symptoms. Thirty-seven percent of patients had incidental brain findings not causally related to the psychosis (brain atrophy, arachnoid cyst, asymmetric lateral ventricles, dilated lateral ventricles, plagiocephaly and falx cerebri calcification. No further medical referral was needed for any of these patients. No significant differences regarding gender, age, diagnosis, duration of untreated psychosis, in-stay and cannabis use were found between patients who had neuroimaging abnormalities versus those without. Discussion. This study suggests that structural neuroimaging exams reveal scarce abnormalities in young patients with first-episode psychosis. Structural neuroimaging is especially useful in first-episode psychosis patients with neurological symptoms, atypical clinical picture and old age.

Recent advances in molecular genetics have allowed the determination of the genetic cause of some childhood non-syndromic deafness. In Portugal only a small proportion of families are referred to a clinical genetics service in order to clarify the etiology of the deafness and to provide genetic counseling. Consequently, there are no published studies of the prior beliefs of parents about the causes of hereditary deafness of their children and their genetic knowledge after receipt of genetic counseling. In order to evaluate the impact of genetic counseling, 44 parents of 24 children with the diagnosis of non-syndromic sensorineural prelingual deafness due to mutations in the GJB2 (connexin 26), completed surveys before and after genetic counseling. Before counseling 13.6 % of the parents knew the cause of deafness; at a post-counseling setting this percentage was significantly higher, with 84.1 % of the parents accurately identifying the etiology. No significant differences were found between the answers of mothers and fathers either before or after genetic counseling. Parents' level of education was a significant factor in pre-test knowledge. After genetic counseling 95.5 % of the parents stated that the consultation had met their expectations, 70.5 % remembered correctly the inheritance pattern, and 93.2 % correctly recalled the chance of risk of deafness. These results underline the importance of genetic counseling in demystifying parents' beliefs about the etiology of their children's deafness.

Objective: To investigate clinical manifestations and neuroimaging in the adult patients with mitochondrial encephalomyopathy (ME). Methods: Systematic study was performed on the clinical features of six adult patients with ME with observations on electromyogram (EMG), electroencephalogram (EEG), the blood lactic acid level, muscle biopsies results and neuroimaging features of CT and MRI. Results: The main clinical features were characterized by seizures, intolerance to exercise, audio-visual dysfunction, mental retardation, and so forth. EMG showed neurogenic damages (4/5 cases); EEG showed extensive mild to severe abnormal activities (3/3 cases) and lactic acidosis was also observed (4 /4 cases). Neuroimaging findings included symmetric supratentorial multi foci lesions, located in frontal, temporal, parietal, and occipital lobes, thalami and basal ganglia with widening of ventricles and cerebral atrophy; the neuroimaging findings also included hyperintensity on T 2 -weighted images and hypointensity/ isointensity on T 1 -weighted images; No stenosis and occlusion of main artery was displayed by magnetic resonance angiography (MRA). Muscle biopsies showed red ragged fiber (RRF) (4/6 cases). Conclusions: Based on clinical features and neuroimaging, diagnosis of ME in early stage may be made in combination with muscle biopsy.

The goals of the study included empirical examination of the utility of the Immediate and Post-Concussion Assessment and Cognitive Testing (ImPACT) test with adolescents who are deaf or hard-of-hearing and to investigate patterns of performance at baseline that may arise in the assessment of this population. Baseline assessment of student-athletes has been conducted on a widespread scale with focus on performance of typically developing student-athletes and some clinical groups, though to date no studies have examined adolescents who are deaf or hard-of-hearing. Retrospective and de-identified ImPACT baseline test used with deaf and hard-of-hearing high-school student-athletes (N = 143; 66% male, mean age = 16.11) was examined. Review indicated significant differences in some composite scores between the deaf and hard-of-hearing group and hearing normative comparisons. A possible marker of task misunderstanding was identified to occur more frequently within the deaf and hard-of-hearing sample (13% in deaf sample vs. .31% in hearing sample). Results may provide support for the consideration and use of additional measures to ensure comprehension of task demands when considering this tool for use with deaf and hard-of-hearing adolescents.

Effectiveness of communication strategies for deaf or hard of hearing workers in group settings.

Science.gov (United States)

Haynes, Scott

2014-01-01

In group settings, background noise and an obstructed view of the speaker are just a few of the issues that can make workplace communication difficult for an individual who is deaf or hard of hearing. Accommodation strategies such as amplification of the speaker's voice or the use of text-based alternatives exist to address these issues. However, recent studies have shown that there are still unmet needs related to workplace communication in group settings for individuals who are deaf or hard of hearing. Identify the most common strategies used by individuals who are deaf or hard of hearing to improve communication in group settings and gauge the perceived effectiveness of those strategies. An online survey was conducted with individuals who self-identified as deaf or hard of hearing. The survey presented specific communication strategies based on three functional approaches (aural/oral, text, visual). The strategies applied to both receptive and expressive communication in five different meeting types ranging in size and purpose. 161 adults (age 22-90 yrs.) with limited hearing ability completed the survey. Text-based strategies were typically the least frequently used strategies in group settings, yet they ranked high in perceived effectiveness for receptive and expressive communication. Those who used an interpreter demonstrated a strong preference for having a qualified interpreter present in the meeting rather than an interpreter acting remotely. For expressive communication, participants in general preferred to use their own voice or signing abilities and ranked those strategies as highly effective. A more accessible workplace for individuals who are deaf or hard of hearing would incorporate more ubiquitous text-based strategy options. Also, qualified interpreters, when used, should be present in the meeting for maximum effectiveness.

Monaural Congenital Deafness Affects Aural Dominance and Degrades Binaural Processing

Cortical development extensively depends on sensory experience. Effects of congenital monaural and binaural deafness on cortical aural dominance and representation of binaural cues were investigated in the present study. We used an animal model that precisely mimics the clinical scenario of unilateral cochlear implantation in an individual with single-sided congenital deafness. Multiunit responses in cortical field A1 to cochlear implant stimulation were studied in normal-hearing cats, bilaterally congenitally deaf cats (CDCs), and unilaterally deaf cats (uCDCs). Binaural deafness reduced cortical responsiveness and decreased response thresholds and dynamic range. In contrast to CDCs, in uCDCs, cortical responsiveness was not reduced, but hemispheric-specific reorganization of aural dominance and binaural interactions were observed. Deafness led to a substantial drop in binaural facilitation in CDCs and uCDCs, demonstrating the inevitable role of experience for a binaural benefit. Sensitivity to interaural time differences was more reduced in uCDCs than in CDCs, particularly at the hemisphere ipsilateral to the hearing ear. Compared with binaural deafness, unilateral hearing prevented nonspecific reduction in cortical responsiveness, but extensively reorganized aural dominance and binaural responses. The deaf ear remained coupled with the cortex in uCDCs, demonstrating a significant difference to deprivation amblyopia in the visual system. PMID:26803166

Functional neuroimaging has been widely used to study the activation patterns of the motor network in patients with Parkinson's disease (PD), but these studies have yielded conflicting results. This meta-analysis of previous neuroimaging studies was performed to identify patterns of abnormal...... movement-related activation in PD that were consistent across studies. We applied activation likelihood estimation (ALE) of functional neuroimaging studies probing motor function in patients with PD. The meta-analysis encompassed data from 283 patients with PD reported in 24 functional neuroimaging studies...

Family therapy in treatment of the deaf: a case report.

Deaf patients with psychological problems have developmental handicaps and clinical characteristics that reduce the effectiveness of traditional modes of psychotherapy. Attempts have been made to utilize individual and group therapy, but family therapy has been largely overlooked as a method of alleviating problems of the deaf. Clinical and research writings provide us with rich insights into the family dynamics of the deaf. These data suggest to the authors that the problems of deaf individuals are largely related to family problems, and therefore merit a family orientation as the focus for treatment. This paper describes an attempt to apply family therapy with a range of deaf patients over a period of two years. From a review of their work, the authors conclude that family therapy can be effective, particularly in the treatment of deaf adolescents and children.

Communication and language barriers isolate Deaf American Sign Language (ASL) users from mass media, healthcare messages, and health care communication, which when coupled with social marginalization, places them at a high risk for inadequate health literacy. Our objectives were to translate, adapt, and develop an accessible health literacy instrument in ASL and to assess the prevalence and correlates of inadequate health literacy among Deaf ASL users and hearing English speakers using a cross-sectional design. A total of 405 participants (166 Deaf and 239 hearing) were enrolled in the study. The Newest Vital Sign was adapted, translated, and developed into an ASL version of the NVS (ASL-NVS). Forty-eight percent of Deaf participants had inadequate health literacy, and Deaf individuals were 6.9 times more likely than hearing participants to have inadequate health literacy. The new ASL-NVS, available on a self-administered computer platform, demonstrated good correlation with reading literacy. The prevalence of Deaf ASL users with inadequate health literacy is substantial, warranting further interventions and research. PMID:26513036

Full Text Available Objective: To investigate the impact of hearing loss in the family dynamics of the deaf child; identify the family’s knowledge about deafness, understand how parents experience the diagnosis and treatment of child with hearing impairment. Methods: The study has aqualitative approach developed at the Center for Integrated Medical Care - NAMI, attached to the University of Fortaleza - UNIFOR located in Fortaleza - CE, Brazil. The participants were six mothers of children with hearing impairment. Data collection was carried outthrough participant observation and semi-structured interview. The Thematic Analysis of Bardin was used for processing the data. Results: After coding, some categories emerged from the discourse: Misinformation of Hearing Loss; impact of the discovery of hearingloss, caregivers and facilitators of the development of the deaf children. Conclusion: The birth of a deaf child alters the previous family balance, causing specific problems, such as the communication barrier, whose solution is related to how to handle the situation. Itis necessary to promote changes, emphasizing the involvement of caregivers and loved as facilitators of deaf child’s development. In Phonoaudiology, this attitude represents discovering new ways to identify the need for the subject, which requires strategies thatvalue their opinion, allowing the expression of expectations, perceptions, representations and feelings.

To evaluate and compare the reading comprehension of deaf students included in regular classrooms of public schools with and without specialized educational support. Observational analytic study with 35 students with sensorineural hearing loss, with and without educational support. All subjects were assessed with the Word Reading Competence Test (WRCT), the Picture-Print Matching Test by Choice (PPMT-C), and the Sentence Reading Comprehension Test (SRCT). In the tests regarding comprehension of words (WRCT and PPMT-C), the results showed no difference in the performance of deaf students who attend and do not attend educational support. Regarding reading comprehension of sentences, the application of the SRCT also did not show differences between the groups of deaf students. A significant correlation was found between age and grade, indicating that the older the students and the higher their educational level, the better their performance in reading sentences. The results indicate that deaf students, regardless of attending educational support, read words better than sentences. There is no difference in reading comprehension between deaf students who receive and do not receive specialized pedagogical monitoring.

Neuroimaging in childhood headache: a systematic review

Alexiou, George A.; Argyropoulou, Maria I.

2013-01-01

Headache is a common complaint in children, one that gives rise to considerable parental concern and fear of the presence of a space-occupying lesion. The evaluation and diagnosis of headache is very challenging for paediatricians, and neuroimaging by means of CT or MRI is often requested as part of the investigation. CT exposes children to radiation, while MRI is costly and sometimes requires sedation or general anaesthesia, especially in children younger than 6 years. This review of the literature on the value of neuroimaging in children with headache showed that the rate of pathological findings is generally low. Imaging findings that led to a change in patient management were in almost all cases reported in children with abnormal signs on neurological examination. Neuroimaging should be limited to children with a suspicious clinical history, abnormal neurological findings or other physical signs suggestive of intracranial pathology. Well-designed prospective studies are needed to better define the clinical findings that warrant neuroimaging in children with headache. (orig.)

Neuroimaging in Mental Health Care: Voices in Translation

Directory of Open Access Journals (Sweden)

Emily L. Borgelt

2012-10-01

Full Text Available Images of brain function, popularly called neuroimages, have become a mainstay of contemporary communication about neuroscience and mental health. Paralleling media coverage of neuroimaging research and the high visibility of clinics selling scans is pressure from sponsors to move basic research about brain function along the translational pathway. Indeed, neuroimaging benefit mental health care with early or tailored intervention, opportunities for education and planning, and access to resources afforded by objectification of disorder. However, risks of premature technology transfer, such as misinterpretation, misrepresentation, and increased stigmatization, could compromise patient care.Stakeholder views on neuroimaging for mental health care are a largely untapped resource of information and guidance for translational efforts. We argue that the insights of key stakeholders – researchers, healthcare providers, patients, and families - have an essential role to play upstream in professional, critical, and ethical discourse about neuroimaging in mental health. Here we integrate previously orthogonal lines of inquiry involving stakeholder research to describe the translational landscape as well as challenges on its horizon.

[How to start a neuroimaging study].

2012-06-01

In order to help researchers understand how to start a neuroimaging study, several tips are described in this paper. These include 1) Choice of an imaging modality, 2) Statistical method, and 3) Interpretation of the results. 1) There are several imaging modalities available in clinical research.

Can Neuroimaging Markers of Vascular Pathology Explain Cognitive Performance in Adults with Sickle Cell Anemia? A Review of the Literature

Science.gov (United States)

Jorgensen, Dana R.; Rosano, Caterina; Novelli, Enrico M.

2017-01-01

Adults with homozygous sickle cell anemia have, on average, lower cognitive function than unaffected controls. The mechanisms underlying cognitive deterioration in this population are poorly understood, but cerebral small vessel disease (CSVD) is likely to be implicated. We conducted a systematic review using the Prisma Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines of articles that included both measures of cognitive function and magnetic resonance imaging (MRI) neuroimaging markers of small vessel disease. While all five studies identified small vessel disease by MRI, only two of them found a significant relationship between structural changes and cognitive performance. Differences in methodologies and small sample sizes likely accounted for the discrepancies between the studies. We conclude that while MRI is a valuable tool to identify markers of CSVD in this population, larger studies are needed to definitely establish a link between MRI-detectable abnormalities and cognitive function in sickle cell anemia.

Empathy and Theory of Mind in Deaf and Hearing Children.

Science.gov (United States)

Peterson, Candida C

2016-04-01

Empathy (or sharing another's emotion) and theory of mind (ToM: the understanding that behavior is guided by true and false beliefs) are cornerstones of human social life and relationships. In contrast to ToM, there has been little study of empathy's development, especially in deaf children. Two studies of a total of 117 children (52 hearing; 65 deaf children of hearing parents) aged 4-13 years were therefore designed to (a) compare levels of empathy in deaf and hearing children, and (b) explore correlations of ToM with empathy in deaf and hearing groups. Results showed that (a) deaf children scored lower in empathy than their hearing peers and (b) empathy and ToM were significantly correlated for deaf children but not for the hearing. Possible reasons for these divergent developmental patterns were considered, along with implications for future research. © The Author 2015. Published by Oxford University Press. All rights reserved.

Anderson, Melissa L; Kobek Pezzarossi, Caroline M

2014-07-01

Using a sample of Deaf female undergraduate students, the current study sought to investigate the prevalence, correlates, and characteristics of intimate partner violence victimization in hearing-Deaf and Deaf-Deaf relationships. Initial results suggest that similarities in hearing status and communication preference are associated with increased levels of negotiation within these relationships. However, compatibility in these areas did not co-occur with significant decreases in physical, psychological, or sexual partner violence. Recommendations for future research as well as implications for clinical and educational practice are outlined. © The Author 2013. Published by Oxford University Press. All rights reserved.

Neuroimaging in eating disorders

Jáuregui-Lobera I

2011-09-01

Full Text Available Ignacio Jáuregui-LoberaBehavioral Sciences Institute and Pablo de Olavide University, Seville, SpainAbstract: Neuroimaging techniques have been useful tools for accurate investigation of brain structure and function in eating disorders. Computed tomography, magnetic resonance imaging, positron emission tomography, single photon emission computed tomography, magnetic resonance spectroscopy, and voxel-based morphometry have been the most relevant technologies in this regard. The purpose of this review is to update the existing data on neuroimaging in eating disorders. The main brain changes seem to be reversible to some extent after adequate weight restoration. Brain changes in bulimia nervosa seem to be less pronounced than in anorexia nervosa and are mainly due to chronic dietary restrictions. Different subtypes of eating disorders might be correlated with specific brain functional changes. Moreover, anorectic patients who binge/purge may have different functional brain changes compared with those who do not binge/purge. Functional changes in the brain might have prognostic value, and different changes with respect to the binding potential of 5-HT1A, 5-HT2A, and D2/D3 receptors may be persistent after recovering from an eating disorder.Keywords: neuroimaging, brain changes, brain receptors, anorexia nervosa, bulimia nervosa, eating disorders

Full Text Available The paper, which provides partial results of a master’s dissertation, has sought to give contribute Sign Language curriculum in the deaf schooling. We began to understand the importance of sign languages for deaf people’s development and found out that a large part of the deaf are from hearing parents, which emphasises the significance of teaching LIBRAS (Brazilian Sign Language in schools for the deaf. We should also consider the importance of this study in building deaf identities and strengthening the deaf culture. We have obtained the theoretical basis in the so-called Deaf Studies and some experts in the curriculum theories. The main objective for this study has been to conduct an analysis of the LIBRAS curriculum at work in schools for the deaf in Rio Grande do Sul, Brazil. The curriculum analysis has shown a degree of diversity: in some curricula, content from one year is repeated in the next one with no articulation. In others, one can find preoccupation for issues of deaf identity and culture, but some of them include contents that are not related to LIBRAS, or the deaf culture, but rather to discipline for the deaf in general. By providing positive and negative aspects, the analysis data may help in discussions about difficulties, progress and problems in LIBRAS teacher education for deaf students.

Postnatal development of the endbulb of Held in congenitally deaf cats

Directory of Open Access Journals (Sweden)

Christa A Baker

2010-05-01

Full Text Available The endbulbs of Held are formed by the ascending branches of myelinated auditory nerve fibers and represent one of the largest synaptic endings in the brain. Normally, these endings are highly branched and each can form up to 1000 dome-shaped synapses. The deaf white cat is a model of congenital deafness involving a type of cochleosaccular degeneration that mimics the Scheibe deformity in humans. Mature deaf white cats exhibit reduced endbulb branching, hypertrophy of postsynaptic densities (PSDs, and changes in synaptic vesicle density. Because cats are essentially deaf at birth, we wanted to determine if the progression of brain abnormalities was linked in time to the failure of normal hearing development. The rationale was that the lack of sound-evoked activity would trigger pathologic change in deaf kittens. The cochleae of deaf cats did not exhibit abnormal morphology at birth. After the first postnatal week, however, the presence of a collapsed scala media signaled the difference between deaf and hearing cats. By working backwards in age, endbulbs of deaf cats expressed flattened and elongated PSDs and increased synaptic vesicle density as compared to normal endbulbs. These differences are present at birth in some white kittens, presaging deafness despite their normal cochlear histology. We speculate that hearing pathology is signaled by a perinatal loss of spontaneous bursting activity in auditory nerve fibers or perhaps by some factor released by hair cell synapses before obliteration of the organ of Corti.

Auditory impairment in mitochondrial disorders are usually due to peripheral sensorineural dysfunction. Central deafness is only rarely reported. We report here an 11-year-old boy with MELAS syndrome who presented with subacute deafness after waking up from sleep. Peripheral hearing loss was rapidly excluded. A brain MRI documented bilateral stroke-like lesions predominantly affecting the superior temporal lobe, including the primary auditory cortex, confirming the central nature of deafness. Slow recovery was observed in the following weeks. This case serves to illustrate the numerous challenges caused by MELAS and the unusual occurrence of acute cortical deafness, that to our knowledge has not be described so far in a child in this setting.

The benefits of sign language for deaf learners with language challenges

Directory of Open Access Journals (Sweden)

Van Staden, Annalene

2009-12-01

Full Text Available This article argues the importance of allowing deaf children to acquire sign language from an early age. It demonstrates firstly that the critical/sensitive period hypothesis for language acquisition can be applied to specific language aspects of spoken language as well as sign languages (i.e. phonology, grammatical processing and syntax. This makes early diagnosis and early intervention of crucial importance. Moreover, research findings presented in this article demonstrate the advantage that sign language offers in the early years of a deaf child’s life by comparing the language development milestones of deaf learners exposed to sign language from birth to those of late-signers, orally trained deaf learners and hearing learners exposed to spoken language. The controversy over the best medium of instruction for deaf learners is briefly discussed, with emphasis placed on the possible value of bilingual-bicultural programmes to facilitate the development of deaf learners’ literacy skills. Finally, this paper concludes with a discussion of the implications/recommendations of sign language teaching and Deaf education in South Africa.

Antenatal diagnosis of congenital deafness.

Isaacson, G

1988-01-01

Advances in the field of antenatal diagnosis have made possible the detection of profound sensorineural hearing loss prior to birth. Fetal motion in response to sound and auditory evoked potential testing can determine the presence of fetal hearing in the third trimester of pregnancy. Imaging modalities including ultrasound, computed tomography, and magnetic resonance imaging hold promise for the diagnosis of some forms of congenital deafness in the second trimester fetus. The methods by which congenital deafness soon may be diagnosed and the implications for the otologist are discussed.

Big Data are of increasing importance in a variety of areas, especially in the biosciences. There is an emerging critical need for Big Data tools and methods, because of the potential impact of advancements in these areas. Importantly, statisticians and statistical thinking have a major role to play in creating meaningful progress in this arena. We would like to emphasize this point in this special issue, as it highlights both the dramatic need for statistical input for Big Data analysis and for a greater number of statisticians working on Big Data problems. We use the field of statistical neuroimaging to demonstrate these points. As such, this paper covers several applications and novel methodological developments of Big Data tools applied to neuroimaging data.

Confronting the language barrier: Theory of mind in deaf children.

Science.gov (United States)

Jones, Anna C; Gutierrez, Roberto; Ludlow, Amanda K

2015-01-01

The current study addressed deaf children's Theory of Mind (ToM) development as measured by a battery of first- and second-order belief tasks. Both a chronological age-matched control group and a younger group of pre-school aged hearing children were compared to a group of deaf children born to hearing parents. A hearing native signer enacted each of the tasks, which were pre-recorded in video clips in English (SSE), British Sign Language (BSL) and spoken English, in order to consider all communication preferences of the deaf children. Results revealed no differences in performance between the deaf and the young hearing children. However, despite the inclusion of ToM tasks based on their preferred mode of communication, the deaf children performed significantly worse at the unexpected-content and second-order belief task compared with their age-matched controls. These findings imply a delay rather than a deficit in ToM in deaf children that could be attributed to limited opportunities to converse and overhear conversations about mental states. None.

Sustained attention, selective attention and cognitive control in deaf and hearing children

Science.gov (United States)

Dye, Matthew W. G.; Hauser, Peter C.

2014-01-01

Deaf children have been characterized as being impulsive, distractible, and unable to sustain attention. However, past research has tested deaf children born to hearing parents who are likely to have experienced language delays. The purpose of this study was to determine whether an absence of auditory input modulates attentional problems in deaf children with no delayed exposure to language. Two versions of a continuous performance test were administered to 37 deaf children born to Deaf parents and 60 hearing children, all aged 6–13 years. A vigilance task was used to measure sustained attention over the course of several minutes, and a distractibility test provided a measure of the ability to ignore task irrelevant information – selective attention. Both tasks provided assessments of cognitive control through analysis of commission errors. The deaf and hearing children did not differ on measures of sustained attention. However, younger deaf children were more distracted by task-irrelevant information in their peripheral visual field, and deaf children produced a higher number of commission errors in the selective attention task. It is argued that this is not likely to be an effect of audition on cognitive processing, but may rather reflect difficulty in endogenous control of reallocated visual attention resources stemming from early profound deafness.

Deaf women: experiences and perceptions of healthcare system access.

Steinberg, Annie G; Wiggins, Erin A; Barmada, Carlin Henry; Sullivan, Vicki Joy

2002-10-01

The authors investigated the knowledge, attitudes, and healthcare experiences of Deaf women. Interviews with 45 deaf women who participated in focus groups in American Sign Language were translated, transcribed, and analyzed. Deaf women's understanding of women's health issues, knowledge of health vocabulary in both English and American Sign Language, common health concerns among Deaf women, and issues of access to information, including pathways and barriers, were examined. As a qualitative study, the results of this investigation are limited and should be viewed as exploratory. A lack of health knowledge was evident, including little understanding of the meaning or value of cancer screening, mammography, or Pap smears; purposes of prescribed medications, such as hormone replacement therapy (HRT); or necessity for other medical or surgical interventions. Negative experiences and avoidance or nonuse of health services were reported, largely due to the lack of a common language with healthcare providers. Insensitive behaviors were also described. Positive experiences and increased access to health information were reported with practitioners who used qualified interpreters. Providers who demonstrated minimal signing skills, a willingness to use paper and pen, and sensitivity to improving communication were appreciated. Deaf women have unique cultural and linguistic issues that affect healthcare experiences. Improved access to health information may be achieved with specialized resource materials, improved prevention and targeted intervention strategies, and self-advocacy skills development. Healthcare providers must be trained to become more effective communicators with Deaf patients and to use qualified interpreters to assure access to healthcare for Deaf women.

Deaf children's use of clear visual cues in mindreading.

Science.gov (United States)

Hao, Jian; Su, Yanjie

2014-11-01

Previous studies show that typically developing 4-year old children can understand other people's false beliefs but that deaf children of hearing families have difficulty in understanding false beliefs until the age of approximately 13. Because false beliefs are implicit mental states that are not expressed through clear visual cues in standard false belief tasks, the present study examines the hypothesis that the deaf children's developmental delay in understanding false beliefs may reflect their difficulty in understanding a spectrum of mental states that are not expressed through clear visual cues. Nine- to 13-year-old deaf children of hearing families and 4-6-year-old typically developing children completed false belief tasks and emotion recognition tasks under different cue conditions. The results indicated that after controlling for the effect of the children's language abilities, the deaf children inferred other people's false beliefs as accurately as the typically developing children when other people's false beliefs were clearly expressed through their eye-gaze direction. However, the deaf children performed worse than the typically developing children when asked to infer false beliefs with ambiguous or no eye-gaze cues. Moreover, the deaf children were capable of recognizing other people's emotions that were clearly conveyed by their facial or body expressions. The results suggest that although theory-based or simulation-based mental state understanding is typical of hearing children's theory of mind mechanism, for deaf children of hearing families, clear cue-based mental state understanding may be their specific theory of mind mechanism.

American Sign Language Syntax and Analogical Reasoning Skills Are Influenced by Early Acquisition and Age of Entry to Signing Schools for the Deaf.

Science.gov (United States)

Henner, Jon; Caldwell-Harris, Catherine L; Novogrodsky, Rama; Hoffmeister, Robert

2016-01-01

Failing to acquire language in early childhood because of language deprivation is a rare and exceptional event, except in one population. Deaf children who grow up without access to indirect language through listening, speech-reading, or sign language experience language deprivation. Studies of Deaf adults have revealed that late acquisition of sign language is associated with lasting deficits. However, much remains unknown about language deprivation in Deaf children, allowing myths and misunderstandings regarding sign language to flourish. To fill this gap, we examined signing ability in a large naturalistic sample of Deaf children attending schools for the Deaf where American Sign Language (ASL) is used by peers and teachers. Ability in ASL was measured using a syntactic judgment test and language-based analogical reasoning test, which are two sub-tests of the ASL Assessment Inventory. The influence of two age-related variables were examined: whether or not ASL was acquired from birth in the home from one or more Deaf parents, and the age of entry to the school for the Deaf. Note that for non-native signers, this latter variable is often the age of first systematic exposure to ASL. Both of these types of age-dependent language experiences influenced subsequent signing ability. Scores on the two tasks declined with increasing age of school entry. The influence of age of starting school was not linear. Test scores were generally lower for Deaf children who entered the school of assessment after the age of 12. The positive influence of signing from birth was found for students at all ages tested (7;6-18;5 years old) and for children of all age-of-entry groupings. Our results reflect a continuum of outcomes which show that experience with language is a continuous variable that is sensitive to maturational age.

Molecular neuroimaging of emotional decision-making.

Science.gov (United States)

Takahashi, Hidehiko

2013-04-01

With the dissemination of non-invasive human neuroimaging techniques such as fMRI and the advancement of cognitive science, neuroimaging studies focusing on emotions and social cognition have become established. Along with this advancement, behavioral economics taking emotional and social factors into account for economic decisions has been merged with neuroscientific studies, and this interdisciplinary approach is called neuroeconomics. Past neuroeconomics studies have demonstrated that subcortical emotion-related brain structures play an important role in "irrational" decision-making. The research field that investigates the role of central neurotransmitters in this process is worthy of further development. Here, we provide an overview of recent molecular neuroimaging studies to further the understanding of the neurochemical basis of "irrational" or emotional decision-making and the future direction, including clinical implications, of the field.

Development of social-cognitive and communication skills in children born deaf.

Science.gov (United States)

Peterson, Candida C

2009-10-01

Central to the interface of social-cognitive and communicative development is the growth of a theory of mind (ToM). ToM is mastered by most hearing children and deaf children of signing deaf parents by the age of 5 or 6 but is often seriously delayed in deaf children of hearing parents. This paper reviews recently published research on deaf children's ToM development and presents an original study consisting of eight longitudinal case histories that collectively map late-signing deaf children's ToM performance from 44 to 158 months of age. While five tentative conclusions can be posited from the collective research so far, further investigation of each of these possibilities is clearly needed.

2017-11-01

Neuropsychology's origins began long before there were any in vivo methods to image the brain. That changed with the advent of computed tomography in the 1970s and magnetic resonance imaging in the early 1980s. Now computed tomography and magnetic resonance imaging are routinely a part of neuropsychological investigations with an increasing number of sophisticated methods for image analysis. This review examines the history of neuroimaging utilization in neuropsychological investigations, highlighting the basic methods that go into image quantification and the various metrics that can be derived. Neuroimaging methods and limitations for identify what constitutes a lesion are discussed. Likewise, the influence of various demographic and developmental factors that influence quantification of brain structure are reviewed. Neuroimaging is an integral part of 21st Century neuropsychology. The importance of neuroimaging to advancing neuropsychology is emphasized.

Implicit sequence learning in deaf children with cochlear implants.

Science.gov (United States)

Conway, Christopher M; Pisoni, David B; Anaya, Esperanza M; Karpicke, Jennifer; Henning, Shirley C

2011-01-01

Deaf children with cochlear implants (CIs) represent an intriguing opportunity to study neurocognitive plasticity and reorganization when sound is introduced following a period of auditory deprivation early in development. Although it is common to consider deafness as affecting hearing alone, it may be the case that auditory deprivation leads to more global changes in neurocognitive function. In this paper, we investigate implicit sequence learning abilities in deaf children with CIs using a novel task that measured learning through improvement to immediate serial recall for statistically consistent visual sequences. The results demonstrated two key findings. First, the deaf children with CIs showed disturbances in their visual sequence learning abilities relative to the typically developing normal-hearing children. Second, sequence learning was significantly correlated with a standardized measure of language outcome in the CI children. These findings suggest that a period of auditory deprivation has secondary effects related to general sequencing deficits, and that disturbances in sequence learning may at least partially explain why some deaf children still struggle with language following cochlear implantation. © 2010 Blackwell Publishing Ltd.

Psychiatric neurosurgery initially developed without the benefit of information provided by modern imaging modalities, and thus lesion targets were selected based on contemporary theories of frontal lobe dysfunction in psychiatric disease. However, by the end of the 20th century, the availability of structural and functional magnetic resonance imaging (fMRI) allowed for the development of mechanistic theories attempting to explain the anatamofunctional basis of these disorders, as well as the efficacy of stereotactic neuromodulatory treatments. Neuroimaging now plays a central and ever-expanding role in the neurosurgical management of psychiatric disorders, by influencing the determination of surgical candidates, allowing individualized surgical targeting and planning, and identifying network-level changes in the brain following surgery. In this review, we aim to describe the coevolution of psychiatric neurosurgery and neuroimaging, including ways in which neuroimaging has proved useful in elucidating the therapeutic mechanisms of neuromodulatory procedures. We focus on ablative over stimulation-based procedures given their historical precedence and the greater opportunity they afford for post-operative re-imaging, but also discuss important contributions from the deep brain stimulation (DBS) literature. We conclude with a discussion of how neuroimaging will transition the field of psychiatric neurosurgery into the era of precision medicine.

P2X2 Dominant Deafness Mutations Have No Negative Effect on Wild-Type Isoform: Implications for Functional Rescue and in Deafness Mechanism

Directory of Open Access Journals (Sweden)

Yan Zhu

2017-11-01

Full Text Available The P2X2 receptor is an ATP-gated ion channel, assembled by three subunits. Recently, it has been found that heterozygous mutations of P2X2 V60L and G353R can cause autosomal dominant nonsyndromic hearing loss. However, the underlying mechanism remains unclear. The fact that heterozygous mutations cause deafness suggests that the mutations may have dominant-negative effect (DNE on wild-type (WT P2X2 isoforms and/or other partners leading to hearing loss. In this study, the effect of these dominant deafness P2X2 mutations on WT P2X2 was investigated. We found that sole transfection of both V60L and G353R deafness mutants could efficiently target to the plasma membrane, like WT P2X2, but exhibit a significantly reduced response to ATP stimulation. Both mutants reduced the channel conductance, but G353R mutation also altered the voltage dependency. Co-expression with WT P2X2 could restore the response to ATP. As the ratio of WT P2X2 vs. mutants increased, the response to ATP was also increased. Computer modeling confirmed that both V60L and G353R dominant-deafness mutant subunits do not have any negative effect on WT P2X2 subunit, when assembled as a heterotrimer. Improper docking or defective gating is the more likely mechanism for impaired channel function by these P2X2 deafness mutations. These results suggest that P2X2 dominant deafness mutations do not have negative effects on WT P2X2 isoforms, and that adding additional WT P2X2 could rescue the lost channel function caused by the deafness mutations. These P2X2 dominant deafness mutations may have negative-effects on other partners leading to hearing loss.

During the past 20 years, numerous neuroimaging experiments have investigated aberrant brain activation during cognitive and emotional processing in patients with unipolar depression (UD). The results of those investigations, however, vary considerably; moreover, previous meta-analyses also yielded inconsistent findings. To readdress aberrant brain activation in UD as evidenced by neuroimaging experiments on cognitive and/or emotional processing. Neuroimaging experiments published from January 1, 1997, to October 1, 2015, were identified by a literature search of PubMed, Web of Science, and Google Scholar using different combinations of the terms fMRI (functional magnetic resonance imaging), PET (positron emission tomography), neural, major depression, depression, major depressive disorder, unipolar depression, dysthymia, emotion, emotional, affective, cognitive, task, memory, working memory, inhibition, control, n-back, and Stroop. Neuroimaging experiments (using fMRI or PET) reporting whole-brain results of group comparisons between adults with UD and healthy control individuals as coordinates in a standard anatomic reference space and using an emotional or/and cognitive challenging task were selected. Coordinates reported to show significant activation differences between UD and healthy controls during emotional or cognitive processing were extracted. By using the revised activation likelihood estimation algorithm, different meta-analyses were calculated. Meta-analyses tested for brain regions consistently found to show aberrant brain activation in UD compared with controls. Analyses were calculated across all emotional processing experiments, all cognitive processing experiments, positive emotion processing, negative emotion processing, experiments using emotional face stimuli, experiments with a sex discrimination task, and memory processing. All meta-analyses were calculated across experiments independent of reporting an increase or decrease of activity in

While reading is challenging for many deaf individuals, some become proficient readers. Little is known about the component processes that support reading comprehension in these individuals. Speech-based phonological knowledge is one of the strongest predictors of reading comprehension in hearing individuals, yet its role in deaf readers is controversial. This could reflect the highly varied language backgrounds among deaf readers as well as the difficulty of disentangling the relative contribution of phonological versus orthographic knowledge of spoken language, in our case ‘English,’ in this population. Here we assessed the impact of language experience on reading comprehension in deaf readers by recruiting oral deaf individuals, who use spoken English as their primary mode of communication, and deaf native signers of American Sign Language. First, to address the contribution of spoken English phonological knowledge in deaf readers, we present novel tasks that evaluate phonological versus orthographic knowledge. Second, the impact of this knowledge, as well as memory measures that rely differentially on phonological (serial recall) and semantic (free recall) processing, on reading comprehension was evaluated. The best predictor of reading comprehension differed as a function of language experience, with free recall being a better predictor in deaf native signers than in oral deaf. In contrast, the measures of English phonological knowledge, independent of orthographic knowledge, best predicted reading comprehension in oral deaf individuals. These results suggest successful reading strategies differ across deaf readers as a function of their language experience, and highlight a possible alternative route to literacy in deaf native signers. Highlights: 1. Deaf individuals vary in their orthographic and phonological knowledge of English as a function of their language experience. 2. Reading comprehension was best predicted by different factors in oral deaf and

Long-distance travel to provide mental health services for deaf people has implications for efficiency, safety, and equality of service. However, uptake of Telemental Health (TMH) has been slow in both deaf and general mental health services. A quantitative study was used to investigate access to TMH and whether staff confidence, experience, or demographics affect TMH use. It was concluded that staff in neither deaf mental health services nor general mental health services had adequate knowledge of or access to TMH. Staff expressed concerns over TMH's appropriateness in their work. Previous use of videoconferencing was assosciated significantly with confidence, but previous use of videophones was not. Neither staff in deaf services nor deaf staff were more experienced with or more confident about videoconferencing, whereas, within deaf services, deaf staff were significantly more confident about videophone use. Training implications are discussed.

Visual attention is a necessary prerequisite to successful communication in sign language. The current study investigated the development of attention-getting skills in deaf native-signing children during interactions with peers and teachers. Seven deaf children (aged 21-39 months) and five adults were videotaped during classroom activities for approximately 30 hr. Interactions were analyzed in depth to determine how children obtained and maintained attention. Contrary to previous reports, children were found to possess a high level of communicative competence from an early age. Analysis of peer interactions revealed that children used a range of behaviors to obtain attention with peers, including taps, waves, objects, and signs. Initiations were successful approximately 65% of the time. Children followed up failed initiation attempts by repeating the initiation, using a new initiation, or terminating the interaction. Older children engaged in longer and more complex interactions than younger children. Children's early exposure to and proficiency in American Sign Language is proposed as a likely mechanism that facilitated their communicative competence.

This dissertation presents research results regarding mathematical modeling in the context of the analysis of functional neuroimages. Specifically, the research focuses on pattern-based analysis methods that recently have become popular analysis tools within the neuroimaging community. Such methods...... neuroimaging data sets are characterized by relatively few data observations in a high dimensional space. The process of building models in such data sets often requires strong regularization. Often, the degree of model regularization is chosen in order to maximize prediction accuracy. We focus on the relative...... be carefully selected, so that the model and its visualization enhance our ability to interpret brain function.

Machine Learning for Neuroimaging with Scikit-Learn

Directory of Open Access Journals (Sweden)

Alexandre eAbraham

2014-02-01

Full Text Available Statistical machine learning methods are increasingly used for neuroimaging data analysis. Their main virtue is their ability to model high-dimensional datasets, e.g. multivariate analysis of activation images or resting-state time series. Supervised learning is typically used in decoding or encoding settings to relate brain images to behavioral or clinical observations, while unsupervised learning can uncover hidden structures in sets of images (e.g. resting state functional MRI or find sub-populations in large cohorts. By considering different functional neuroimaging applications, we illustrate how scikit-learn, a Python machine learning library, can be used to perform some key analysis steps. Scikit-learn contains a very large set of statistical learning algorithms, both supervised and unsupervised, and its application to neuroimaging data provides a versatile tool to study the brain.

Foster, S; Long, G; Snell, K

1999-01-01

This article explores how students who are deaf and their instructors experience mainstream college classes. Both quantitative and qualitative procedures were used to examine student access to information and their sense of belonging and engagement in learning. Instructors were asked to discuss their approach to teaching and any instructional modifications made to address the needs of deaf learners. Results indicate that deaf students viewed classroom communication and engagement in a similar manner as their hearing peers. Deaf students were more concerned about the pace of instruction and did not feel as much a part of the 'university family' as did their hearing peers. Faculty generally indicated that they made few if any modifications for deaf students and saw support service faculty as responsible for the success or failure of these students. We discuss results of these and additional findings with regard to barriers to equal access and strategies for overcoming these barriers.

The etiology of sudden deafness can remain undetermined despite extensive investigation. This study addresses the value of magnetic resonance imaging in the analysis of sudden deafness patients.Study Design: transversal cohort.Material And Method: In a prospective study, 49 patients attended at otolaryngology emergency room of Federal University of Sao Paulo - Escola Paulista de Medicina, from April 2001 to May 2003, were submitted to magnetic resonance imaging.Results: Magnetic Resonance abnormalities were seen in 23 (46.9%) patients and revealed two tumors suggestive of meningioma, three vestibular schwannomas, thirteen microangiopathic changes of the brain and five (21.7%) pathological conditions of the labyrinth.Conclusion: Sudden deafness should be approached as a symptom common to different diseases. The presence of cerebellopontine angle tumors in 10.2% of our cases, among other treatable causes, justifies the recommendation of gadolinium-enhanced magnetic resonance use, not only to study the auditory peripheral pathway, but to study the whole auditory pathway including the brain.

Self-determination is a combination of attitudes, knowledge, and skills that enables individuals to make choices and engage in goal-directed, self-regulated behavior. Research in special education has demonstrated the benefits of promoting self-determination in achieving positive adult outcomes. However, to date, very little has been written about self-determination as it relates to the education of students who are deaf or hard of hearing. This article provides an overview of self-determination, suggestions for instructional planning, and guidance on resources that can be used to gather additional information.

Pituitary gland in psychiatric disorders: a review of neuroimaging findings.

Science.gov (United States)

Atmaca, Murad

2014-08-01

In this paper, it was reviewed neuroimaging results of the pituitary gland in psychiatric disorders, particularly schizophrenia, mood disorders, anxiety disorders, and somatoform disorders. The author made internet search in detail by using PubMed database including the period between 1980 and 2012 October. It was included in the articles in English, Turkish and French languages on pituitary gland in psychiatric disorders through structural or functional neuroimaging results. After searching mentioned in the Methods section in detail, investigations were obtained on pituitary gland neuroimaging in a variety of psychiatric disorders. There have been so limited investigations on pituitary neuroimaging in psychiatric disorders including major psychiatric illnesses like schizophrenia and mood disorders. Current findings are so far from the generalizability of the results. For this reason, it is required to perform much more neuroimaging studies of pituitary gland in all psychiatric disorders to reach the diagnostic importance of measuring it.

2009-08-01

The identification of the molecular basis of deafness in the last decade has made a remarkable impact on genetic counseling and diagnostics for the hearing impaired population. Since the discovery of the most prevalent form of deafness associated with mutations in the GJB2 (connexin 26) gene, many other genes have been found worldwide, with a subset of these, including unique mutations, in Israel. Here, we review the current status of deafness genes in Israel and report one known mutation in a syndromic form of deafness, Usher syndrome, described in the Jewish Israeli population for the first time. In the future, the identification of specific mutations may be relevant for specific types of treatment.

2013-01-01

The present study examined whether full access to sign language as a medium for instruction could influence performance in Theory of Mind (ToM) tasks. Three groups of Italian participants (age range: 6-14 years) participated in the study: Two groups of deaf signing children and one group of hearing-speaking children. The two groups of deaf children differed only in their school environment: One group attended a school with a teaching assistant (TA; Sign Language is offered only by the TA to a single deaf child), and the other group attended a bilingual program (Italian Sign Language and Italian). Linguistic abilities and understanding of false belief were assessed using similar materials and procedures in spoken Italian with hearing children and in Italian Sign Language with deaf children. Deaf children attending the bilingual school performed significantly better than deaf children attending school with the TA in tasks assessing lexical comprehension and ToM, whereas the performance of hearing children was in between that of the two deaf groups. As for lexical production, deaf children attending the bilingual school performed significantly better than the two other groups. No significant differences were found between early and late signers or between children with deaf and hearing parents.

Cochleovestibular symptoms, such as vertigo, tinnitus, and sudden deafness, are common manifestations of microvascular diseases. However, it is unclear whether these symptoms occurred preceding the diagnosis of peripheral artery occlusive disease (PAOD). Therefore, the aim of this case-control study was to investigate the risk of PAOD among patients with vertigo, tinnitus, and sudden deafness using a nationwide, population-based health claim database in Taiwan. We identified 5,340 adult patients with PAOD diagnosed between January 1, 2006 and December 31, 2010 and 16,020 controls, frequency matched on age interval, sex, and year of index date, from the Taiwan National Health Insurance Research Database. Risks of PAOD in patients with vertigo, tinnitus, or sudden deafness were separately evaluated with multivariate logistic regression analyses. Of the 5,340 patients with PAOD, 12.7%, 6.7%, and 0.3% were diagnosed with vertigo, tinnitus, and sudden deafness, respectively. In the controls, 10.6%, 6.1%, and 0.3% were diagnosed with vertigo (P vertigo (adjusted odds ratio = 1.12, P = 0.027) but not in those with tinnitus or sudden deafness. A modest increase in the risk of PAOD was observed among Taiwanese patients with vertigo, after adjustment for comorbidities.

This paper aims to: (1) explore usage and accessibility of sign language interpreters, (2) appraise the levels of quality of life (QOL) of deaf adults residing in New Zealand, and (3) consider the impact of access to and usage of sign language interpreters on QOL. Sixty-eight deaf adults living in New Zealand participated in this study. Two questionnaires were employed: a 12-item instrument about access and use of New Zealand sign language interpreters and the abbreviated version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF). The results showed that 39% of this sample felt that they were unable to adequately access interpreting services. Moreover, this group scored significantly lower than a comparable hearing sample on all four WHOQOL-BREF domains. Finally, the findings revealed that access to good quality interpreters were associated with access to health services, transport issues, engagement in leisure activities, gaining more information, mobility and living in a healthy environment. These findings have consequences for policy makers and agencies interested in ensuring that there is an equitable distribution of essential services for all groups within New Zealand which inevitably has an impact on the health of the individual.

Full Text Available O objetivo do presente artigo é proceder a uma análise dos livros de literatura infantil Cinderela Surda e Rapunzel Surda, focalizando os sentidos produzidos sobre identidades e diferenças. As análises desses livros pretendem contribuir para a discussão da produção de uma literatura surda, que está vinculada às discussões sobre cultura e identidade. Na investigação desses materiais, os textos e as imagens produzidas evidenciam que os autores buscam o caminho da auto-representação do grupo de surdos, através da luta pelo estabelecimento do que reconhecem como suas identidades e suas diferenças. Tais evidências estão no uso da língua de sinais, em suas formas de narrar as histórias e/ou de adaptar histórias clássicas, tendo como base suas formas de existência, suas formas de ler, traduzir, conceber e julgar os produtos culturais que consomem e que produzem. This article aims to present an analysis of the fairy tales, Deaf Cinderella and Deaf Rapunzel, focusing on the meanings produced from identities and differences. The analyses of these two books intend to give a contribution to the discussion on the production of deaf literature, which is linked to the discussions on culture and identity. In the investigation of these books, the texts and the images produced show that the authors seek the path to self- representation of the deaf community, through the struggle for the establishment of what they recognize as their identities and differences. Such evidences are in the use of sign language, in their ways of narrating their stories and/or of adapting classic fairy tales, having as a basis their existential ways of being, their ways of reading, translating, conceiving and judging the cultural products which they consume and produce.

Full Text Available Background: Long QT syndromes (LQT are genetic abnormalities of ventricular repo-larization, with an estimated incidence of about one per 10000 births. It is characterized by prolongation of the QT interval in electrocardiogram (EKG and associated with a high risk for syncope and sudden death in patients. Type of this syndrome is association with congenital deafness. Our objective was to evaluate QT interval in children with congenital deafness.Methods: For 219 patients referred to Imam Khomeini Hospital audiometric clinic in 2011, questionnaire were completed. A total of 23 congenitally deaf children were incl-uded. All patients’ examinations were done by a pediatric cardiologist. Electrocardio-gram is conducted in all children (23 patients with sever and deep congenital deafness. Then the QT interval was measured based on Bazett’s formula. Echocardiography was also performed in these children to assess left ventricular function and the presence of mitral valve prolapse.Results: The overall patients were two hundred and nineteen children. A total of twenty three congenitally deaf children were included and electrocardiogram was obtained. Three children had obviously prolonged QTc (0.48±0.02 second. The median age of them was 6.1±5 year, the median weight was 18±11.3 kilogram and the median of QT interval was 0.48±0.02 second.Conclusion: The QT interval obtained 0.48±0.02 second. In the present study we found prolonged QT in congenital deafness, thus we recommend to evaluate the electrocardio-gram of children with congenital deafness.

The present study compared the reading skills of Black Deaf and White Deaf individuals, investigating the influence of American Sign Language (ASL), culture, family characteristics, reading experience, and education. (The descriptor Black is used throughout the present article, as Black Deaf individuals prefer this term to African American. For purposes of parallel construction, the term White is used instead of European American.) It was found that Black Deaf study participants scored lower on measures of both reading and ASL. These findings provide implications for possible interventions at the primary, secondary, and college levels of education.

Hadjikakou, Kika; Nikolaraizi, Magda

2011-01-01

The present study investigated the current functions of Deaf clubs in Cyprus and in Greece. The researchers conducted in-depth semistructured interviews with 24 Cypriot and 22 Greek deaf individuals ages 19-54 years. The researchers found that the Deaf clubs in both countries provide a gathering place for deaf people, organize social and sport activities, and promote their demands through legislation. In addition, Deaf clubs maintain and transmit Deaf culture and history to future generations, offer Deaf role models to young deaf children and their families, and provide Deaf awareness to hearing people (e.g., through sign languages classes). The study participants also stressed the role of Deaf clubs in deaf people's lives, unity, and prospects for future progress.

This study investigates the relationship between critical health literacy (CHL) and discussion of health information among college deaf students who use American Sign Language. CHL is crucial in making appropriate health-related decisions for oneself and aiding others in making good health-choices. Research on general youth population shows that frequent health-related discussions with both friends and family is associated with higher health literacy. However, for our sample of deaf college-aged students who might have had less access to communication at home, we hypothesize that health-related discussions with same-age peers may be more important for critical health literacy. We asked two questions to assess the frequency of health-related discussions with friends and families: "How often do you discuss health-related information with your friends" and "How often do you discuss your family medical history with your family?". Participants rated their experience on a scale from 1-5 (1=never, 5=always). To assess CHL, 38 deaf and 38 hearing participants were shown a short scenario that showed a woman confiding in her friend after finding a lump in her breast. Participants were then asked what the friend should say. Responses were scored by a team of 3 raters using a CHL rubric. As predicted, results showed a strong relationship between discussion of health-related information with friends and CHL in both deaf and hearing samples. Discussion with family was linked to CHL only for hearing participants, but not deaf participants in our study. These findings underscore the importance of socializing with health-literate, accessible peers to improve the health literacy and health outcomes of all deaf people. © The Author 2017.

Data sharing and mediation across disparate neuroimaging repositories requires extensive effort to ensure that the different domains of data types are referred to by commonly agreed upon terms. Within the SchizConnect project, which enables querying across decentralized databases of neuroimaging, clinical, and cognitive data from various studies of schizophrenia, we developed a model for each data domain, identified common usable terms that could be agreed upon across the repositories, and linked them to standard ontological terms where possible. We had the goal of facilitating both the current user experience in querying and future automated computations and reasoning regarding the data. We found that existing terminologies are incomplete for these purposes, even with the history of neuroimaging data sharing in the field; and we provide a model for efforts focused on querying multiple clinical neuroimaging repositories.

The purpose of this study was to describe the everyday activities and social contacts among older deaf sign language users, and to investigate relationships between these phenomena and the health and well-being within this group. The study population comprised deaf sign language users, 65 years...... or older, in Sweden. Data collection was based on interviews in sign language, including open-ended questions covering everyday activities and social contacts as well as self-rated instruments measuring aspects of health and subjective well-being. The results demonstrated that the group of participants...... aspects of health and subjective well-being and the frequency of social contacts with family/relatives or visiting the deaf club and meeting friends. It is concluded that the variety of activities at the deaf clubs are important for the subjective well-being of older deaf sign language users. Further...

25 years of neuroimaging in amyotrophic lateral sclerosis

Science.gov (United States)

Foerster, Bradley R.; Welsh, Robert C.; Feldman, Eva L.

2014-01-01

Amyotrophic lateral sclerosis (ALS) is a fatal motor neuron disease for which a precise cause has not yet been identified. Standard CT or MRI evaluation does not demonstrate gross structural nervous system changes in ALS, so conventional neuroimaging techniques have provided little insight into the pathophysiology of this disease. Advanced neuroimaging techniques—such as structural MRI, diffusion tensor imaging and proton magnetic resonance spectroscopy—allow evaluation of alterations of the nervous system in ALS. These alterations include focal loss of grey and white matter and reductions in white matter tract integrity, as well as changes in neural networks and in the chemistry, metabolism and receptor distribution in the brain. Given their potential for investigation of both brain structure and function, advanced neuroimaging methods offer important opportunities to improve diagnosis, guide prognosis, and direct future treatment strategies in ALS. In this article, we review the contributions made by various advanced neuroimaging techniques to our understanding of the impact of ALS on different brain regions, and the potential role of such measures in biomarker development.

The loss of hearing modifies in every respect the relations between a child and his environment and results in serious communication problems. An early diagnosis and a coherent management using all the techniques that facilitate communication can thoroughly alter the consequences of deafness. The therapeutic and educative planning must be done by a competent, multidisciplinary team working in close cooperation with the child's parents. The plan must be adjusted to each individual child and constantly readjusted, the target being the social integration of deaf children when they reach adulthood.

Extended visual regions among the deaf

Whatever is the source of the deafness (genetic or acquired in the childhood) it leads to a partial re-arrangement of brain. It has been shown at animals that nerve cells of the auditive cortex acquire some characteristics of the visual nerve cells. At men, the NMR imaging confirms it: it seems that a part of the visual cortex appropriates some cortex zones which are normally intended to audition. It has been verified too that the deaf language solicit more the right hemisphere than the spoken language. (O.M.)

The neurobiological basis and nosological status of schizoaffective disorder remains elusive and controversial. This study provides a systematic review of neurocognitive and neuroimaging findings in the disorder. A comprehensive literature search was conducted via PubMed, ScienceDirect, Scopus and Web of Knowledge (from 1949 to 31st March 2015) using the keyword 'schizoaffective disorder' and any of the following terms: 'neuropsychology', 'cognition', 'structural neuroimaging', 'functional neuroimaging', 'multimodal', 'DTI' and 'VBM'. Only studies that explicitly examined a well defined sample, or subsample, of patients with schizoaffective disorder were included. Twenty-two of 43 neuropsychological and 19 of 51 neuroimaging articles fulfilled inclusion criteria. We found a general trend towards schizophrenia and schizoaffective disorder being related to worse cognitive performance than bipolar disorder. Grey matter volume loss in schizoaffective disorder is also more comparable to schizophrenia than to bipolar disorder which seems consistent across further neuroimaging techniques. Neurocognitive and neuroimaging abnormalities in schizoaffective disorder resemble more schizophrenia than bipolar disorder. This is suggestive for schizoaffective disorder being a subtype of schizophrenia or being part of the continuum spectrum model of psychosis, with schizoaffective disorder being more skewed towards schizophrenia than bipolar disorder. © 2016 John Wiley & Sons A/S.

2017-12-01

The research described was undertaken as part of a Sub-Regional Disability Strategy 2017-2022 across the Wairarapa, Hutt Valley and Capital and Coast District Health Boards (DHBs). The aim was to investigate deaf New Zealand Sign Language (NZSL) users' quality of access to health services. Findings have formed the basis for developing a 'NZSL plan' for DHBs in the Wellington sub-region. Qualitative data was collected from 56 deaf participants and family members about their experiences of healthcare services via focus group, individual interviews and online survey, which were thematically analysed. Contextual perspective was gained from 57 healthcare professionals at five meetings. Two professionals were interviewed, and 65 staff responded to an online survey. A deaf steering group co-designed the framework and methods, and validated findings. Key issues reported across the health system include: inconsistent interpreter provision; lack of informed consent for treatment via communication in NZSL; limited access to general health information in NZSL and the reduced ability of deaf patients to understand and comply with treatment options. This problematic communication with NZSL users echoes international evidence and other documented local evidence for patients with limited English proficiency. Deaf NZSL users face multiple barriers to equitable healthcare, stemming from linguistic and educational factors and inaccessible service delivery. These need to be addressed through policy and training for healthcare personnel that enable effective systemic responses to NZSL users. Deaf participants emphasise that recognition of their identity as members of a language community is central to improving their healthcare experiences.

As an example, we discuss the fairy tale Cinderella, which turns into Deaf Cinderella when re-told by college educated deaf adults. The literature produced by deaf sign language users clearly shows their input into the stories, by adding the history of their own education and the history of the birth of deaf communities. That parallel can be drawn from the aforementioned story, where the deaf prince learns sign language with the help of a hearing sign language teacher and Cinderella, who is plebeian, acquires sign language through contact with other deaf people.

Full Text Available In this work surveys of latent motility abilities and skills of school children are shown. The sample for this survey was consisted of two subsamples. First one has consisted of deaf children N=29, and the second one has consisted hearing children of same age N=69. Subsamples of deaf is chosen according to model of applied sample, and subsample is chosen randomly, so two stages group sample N=90 has been created. After quantitative differences have been discovered between subsamples, hearing pupils have shown statistically better results at motility skills and techniques than deaf children and cumulative results have been subjected to inter correlation of variables. The target of using this method was determination of saturation of common variability through saturation of variables and their correlation by Ortoblique rotation for determination of latent information that are going to serve as practical guides at education and deaf children treatment, because of improvement of their motility abilities and skills according to hearing children. Three factors have been singled out as main preview of measurement on manifest variables. According to first review of measuring it has been established that at deaf children is needed to work on improving of physical abilities and mobility and then developed motility abilities and skills. Their information has been gained most probably by non system fluctuations as information about ability of balance maintaining which is most probably non dependable of motility abilities and skills as at deaf and hearing children too. According to this survey by entering the structure of measuring instrument it is possible to create programs for improving motility abilities and skills at deaf children.

Full Text Available Bacground/Aim. Almost 200 cochlear implantations were done in the four centers (two in Belgrade, per one in Novi Sad and Niš in Serbia from 2002 to 2009. Less than 10% of implantees were postlingually deaf adults. The vast majority, i.e. 90% were pre- and perilingually profoundly deaf children. The aim of this study was to assess the influence of improved auditory perception due to cochlear implantation on comprehension of abstract words in children as compared with hearing impaired children with conventional hearing aids and normal hearing children. Methods. Thirty children were enrolled in this study: 20 hearing impaired and 10 normal hearing. The vocabulary test was used. Results. The overall results for the whole test (100 words showed a significant difference in favor of the normal hearing as compared with hearing impaired children. The normal hearing children successfully described or defined 77.93% of a total of 100 words. Success rate for the cochlear implanted children was 26.87% and for the hearing impaired children with conventional hearing aids 20.32%. Conclusion. Testing for abstract words showed a statistically significant difference between the cochlear implanted and the hearing impaired children with hearing aids (Mann- Whitney U-test, p = 0.019 implying considerable advantage of cochlear implants over hearing aids regarding successful speech development in prelingually deaf children.

Examining Deaf Students' Equitable Access to Science vis-a-vis Contemporary Pedagogical Practices

Ross, Annemarie D.

As a Deaf individual, it is important to ensure the growth of the Deaf community as science-literate members of society. While many predecessors have contributed to the body of research in Deaf pedagogy, there is still much to be done in safeguarding Deaf learners' equitable access to science education. One area of concern is in narrowing the statistically significant gap in Climate Change knowledge between Deaf students' and Hearing students' at the Rochester Institute of Technology. It is within this topic that the writing-to-learn-science framework is practiced and Deaf students in the Laboratory Science Technology program at the National Technical Institute for the Deaf participate in a study to assess whether or not the use of writing-to-learn-science strategies help them become better scientists, writers and learners. In this study, the social constructivist framework (Vygotsky, 1987) is used to study the impact of the use of the Berland and Reiser (2009) argumentation framework, so that they write-to-learn-science through the steps of sense-making, articulation and persuasion.

Deaf: A Concept Analysis From a Cultural Perspective Using the Wilson Method of Concept Analysis Development.

Science.gov (United States)

Pendergrass, Kathy M; Newman, Susan D; Jones, Elaine; Jenkins, Carolyn H

2017-07-01

The purpose of this article is to provide an analysis of the concept Deaf to increase health care provider (HCP) understanding from a cultural perspective. Deaf signers, people with hearing loss who communicate primarily in American Sign Language (ASL), generally define the term Deaf as a cultural heritage. In the health care setting, the term deaf is most often defined as a pathological condition requiring medical intervention. When HCPs are unaware that there are both cultural and pathological views of hearing loss, significant barriers may exist between the HCP and the Deaf individual. The concept of Deaf is analyzed using the Wilsonian method. Essential elements of the concept "Deaf" from a cultural perspective include a personal choice to communicate primarily in ASL and identify with the Deaf community. Resources for HCPs are needed to quickly identify Deaf signers and provide appropriate communication.

This paper describes the Imperial College near infrared spectroscopy neuroimaging analysis (ICNNA) software tool for functional near infrared spectroscopy neuroimaging data. ICNNA is a MATLAB-based object-oriented framework encompassing an application programming interface and a graphical user interface. ICNNA incorporates reconstruction based on the modified Beer-Lambert law and basic processing and data validation capabilities. Emphasis is placed on the full experiment rather than individual neuroimages as the central element of analysis. The software offers three types of analyses including classical statistical methods based on comparison of changes in relative concentrations of hemoglobin between the task and baseline periods, graph theory-based metrics of connectivity and, distinctively, an analysis approach based on manifold embedding. This paper presents the different capabilities of ICNNA in its current version.

Reading books with young deaf children: strategies for mediating between American Sign Language and English.

Science.gov (United States)

Berke, Michele

2013-01-01

Research on shared reading has shown positive results on children's literacy development in general and for deaf children specifically; however, reading techniques might differ between these two populations. Families with deaf children, especially those with deaf parents, often capitalize on their children's visual attributes rather than primarily auditory cues. These techniques are believed to provide a foundation for their deaf children's literacy skills. This study examined 10 deaf mother/deaf child dyads with children between 3 and 5 years of age. Dyads were videotaped in their homes on at least two occasions reading books that were provided by the researcher. Descriptive analysis showed specifically how deaf mothers mediate between the two languages, American Sign Language (ASL) and English, while reading. These techniques can be replicated and taught to all parents of deaf children so that they can engage in more effective shared reading activities. Research has shown that shared reading, or the interaction of a parent and child with a book, is an effective way to promote language and literacy, vocabulary, grammatical knowledge, and metalinguistic awareness (Snow, 1983), making it critical for educators to promote shared reading activities at home between parent and child. Not all parents read to their children in the same way. For example, parents of deaf children may present the information in the book differently due to the fact that signed languages are visual rather than spoken. In this vein, we can learn more about what specific connections deaf parents make to the English print. Exploring strategies deaf mothers may use to link the English print through the use of ASL will provide educators with additional tools when working with all parents of deaf children. This article will include a review of the literature on the benefits of shared reading activities for all children, the relationship between ASL and English skill development, and the techniques

Cross-modal activation of auditory regions during visuo-spatial working memory in early deafness.

Early deafness can reshape deprived auditory regions to enable the processing of signals from the remaining intact sensory modalities. Cross-modal activation has been observed in auditory regions during non-auditory tasks in early deaf subjects. In hearing subjects, visual working memory can evoke activation of the visual cortex, which further contributes to behavioural performance. In early deaf subjects, however, whether and how auditory regions participate in visual working memory remains unclear. We hypothesized that auditory regions may be involved in visual working memory processing and activation of auditory regions may contribute to the superior behavioural performance of early deaf subjects. In this study, 41 early deaf subjects (22 females and 19 males, age range: 20-26 years, age of onset of deafness memory task than did the hearing controls. Compared with hearing controls, deaf subjects exhibited increased activation in the superior temporal gyrus bilaterally during the recognition stage. This increased activation amplitude predicted faster and more accurate working memory performance in deaf subjects. Deaf subjects also had increased activation in the superior temporal gyrus bilaterally during the maintenance stage and in the right superior temporal gyrus during the encoding stage. These increased activation amplitude also predicted faster reaction times on the spatial working memory task in deaf subjects. These findings suggest that cross-modal plasticity occurs in auditory association areas in early deaf subjects. These areas are involved in visuo-spatial working memory. Furthermore, amplitudes of cross-modal activation during the maintenance stage were positively correlated with the age of onset of hearing aid use and were negatively correlated with the percentage of lifetime hearing aid use in deaf subjects. These findings suggest that earlier and longer hearing aid use may inhibit cross-modal reorganization in early deaf subjects. Granger

The effectiveness of international development assistance from American organizations to deaf communities in Jamaica.

Science.gov (United States)

Wilson, Amy T

American organizations bringing assistance to deaf people in developing countries unintentionally create relationships of dependency or oppression rather than relationships of support. Using qualitative methods, the author examined the effectiveness of development assistance provided to the Jamaican Deaf community by two American churches, one American nongovernmental organization, and one U.S. federal agency. Documents were reviewed and observations were made. Interviews were conducted with more than 60 deaf and hearing people involved with the American organizations, the Jamaican organizations, and deaf Jamaican beneficiaries. The author concludes that the Jamaican Deaf community was often excluded in planning, designing, or evaluating programs, and was unsatisfied with the American assistance it received. Results also indicate that the American organizations were poorly prepared to work with the Deaf community. Suggestions for American organizations wishing to strengthen and empower deaf people through development assistance in developing countries are proposed.

The contribution of phonological knowledge, memory, and language background to reading comprehension in deaf populations

Directory of Open Access Journals (Sweden)

Elizabeth Ann Hirshorn

2015-08-01

Full Text Available While reading is challenging for many deaf individuals, some become proficient readers. Yet we do not know the component processes that support reading comprehension in these individuals. Speech-based phonological knowledge is one of the strongest predictors of reading comprehension in hearing individuals, yet its role in deaf readers is controversial. This could reflect the highly varied language backgrounds among deaf readers as well as the difficulty of disentangling the relative contribution of phonological versus orthographic knowledge of spoken language, in our case ‘English’, in this population. Here we assessed the impact of language experience on reading comprehension in deaf readers by recruiting oral deaf individuals, who use spoken English as their primary mode of communication, and deaf native signers of American Sign Language. First, to address the contribution of spoken English phonological knowledge in deaf readers, we present novel tasks that evaluate phonological versus orthographic knowledge. Second, the impact of this knowledge, as well as verbal short-term memory and long-term memory skills, on reading comprehension was evaluated. The best predictor of reading comprehension differed as a function of language experience, with long-term memory, as measured by free recall, being a better predictor in deaf native signers than in oral deaf. In contrast, the measures of English phonological knowledge, independent of orthographic knowledge, best predicted reading comprehension in oral deaf individuals. These results suggest successful reading strategies differ across deaf readers as a function of their language experience, and highlight a possible alternative route to literacy in deaf native signers.

From the Editors: This article represents another in our series of "classics" that helped to shape the field of deaf studies and deaf education. The article first appeared as Chapter Two in Sound and Sign: Childhood Deafness and Mental Health, H. S. Schlesinger and K. P. Meadow (1972), Berkeley: University of California Press. The book reported pioneering research and clinical mental health services at the Langley Porter Neuropsychiatric Institute, University of California, San Francisco. For current readers, some of the language may seem out of date, and the Editors have made several minor modifications to ensure that readers fully recognize the original intention of the author. (Such modifications are indicated by square brackets or ellipses for contemporary purposes, but the intentions of the original all have been maintained, and Editors' notes are indicated as such to distinguish them from the Authors' notes.) Nevertheless, many of the ideas are fresh and important. Indeed, some passages serve as particular reminders of significant changes in opportunities for and attitudes about Deaf people over the past three decades. Many of these changes resulted directly from the work of Dr. Schlesinger and her colleagues.

Neuroimaging techniques including structural magnetic resonance imaging (MRI) and functional positron emission tomography (PET) are useful in categorizing various midbrain-hindbrain (MHB) malformations, both in allowing diagnosis and in helping to understand the developmental processes that were disturbed. Brain imaging phenotypes of numerous malformations are characteristic features that help in guiding the genetic testing in case of direct neuroimaging-genotype correlation or, at least, to differentiate among MHB malformations entities. The present review aims to provide the reader with an update of the use of neuroimaging applications in the fine analysis of MHB malformations, using a comprehensive, recently proposed developmental and genetic classification. We have performed an extensive systematic review of the literature, from the embryology main steps of MHB development through the malformations entities, with regard to their molecular and genetic basis, conventional MRI features, and other neuroimaging characteristics. We discuss disorders in which imaging features are distinctive and how these features reflect the structural and functional impairment of the brain. Recognition of specific MRI phenotypes, including advanced imaging features, is useful to recognize the MHB malformation entities, to suggest genetic investigations, and, eventually, to monitor the disease outcome after supportive therapies.

Nipype: A flexible, lightweight and extensible neuroimaging data processing framework

Directory of Open Access Journals (Sweden)

Krzysztof eGorgolewski

2011-08-01

Full Text Available Current neuroimaging software offer users an incredible opportunity to analyze their data in different ways, with different underlying assumptions. Several sophisticated software packages (e.g., AFNI, BrainVoyager, FSL, FreeSurfer, Nipy, R, SPM are used to process and analyze large and often diverse (highly multi-dimensional data. However, this heterogeneous collection of specialized applications creates several issues that hinder replicable, efficient and optimal use of neuroimaging analysis approaches: 1 No uniform access to neuroimaging analysis software and usage information; 2 No framework for comparative algorithm development and dissemination; 3 Personnel turnover in laboratories often limits methodological continuity and training new personnel takes time; 4 Neuroimaging software packages do not address computational efficiency; and 5 Methods sections in journal articles are inadequate for reproducing results. To address these issues, we present Nipype (Neuroimaging in Python: Pipelines and Interfaces; http://nipy.org/nipype, an open-source, community-developed, software package and scriptable library. Nipype solves the issues by providing Interfaces to existing neuroimaging software with uniform usage semantics and by facilitating interaction between these packages using Workflows. Nipype provides an environment that encourages interactive exploration of algorithms, eases the design of Workflows within and between packages, allows rapid comparative development of algorithms and reduces the learning curve necessary to use different packages. Nipype supports both local and remote execution on multi-core machines and clusters, without additional scripting. Nipype is BSD licensed, allowing anyone unrestricted usage. An open, community-driven development philosophy allows the software to quickly adapt and address the varied needs of the evolving neuroimaging community, especially in the context of increasing demand for reproducible research.

Political-pedagogical unfoldings of bilingualism for deaf people: reflexions and directing

Sueli Fernandes

2009-09-01

Full Text Available The article talks about bilingualism for deaf people, it’s implications in the educational process, as well as in some of the inclusive linguistic politics unfoldings proposed officially from the end of the decade of 1990 for this segment. The sociocultural and linguistic characteristics of the Brazilian deaf people communities are argued and also the importance of the same ones to be known and socially valued. Some lines of direction and challenges are pointed for the access and remaining of the deaf students in the school educational process. Finally, the text reflects about the bilingual education programs for deaf students, considering that these are complex, specially because it crosses economic ideological, cultural contradictory and heterogeneous interests.

Full Text Available The education of deaf students normally begins to be studied from Ponce de Leon in a monastery of Burgos; but until this moment people with hearing loss or deafness have had moments in history with more or less acceptance. In primitive societies both could be protected as repudiated , depending on whether the deafness was considered a punishment or a gift of God holder . Over time , history has continued to generate periods of more or less accepted to be people, but especially after the Middle Ages and the eighteenth century past has been where most progress has been made towards integration and inclusion.

Bear, Joshua J; Gelfand, Amy A; Goadsby, Peter J; Bass, Nancy

2017-08-01

To investigate the common thinking, as reinforced by the International Classification of Headache Disorders, 3rd edition (beta), that occipital headaches in children are rare and suggestive of serious intracranial pathology. We performed a retrospective chart review cohort study of all patients ≤18 years of age referred to a university child neurology clinic for headache in 2009. Patients were stratified by headache location: solely occipital, occipital plus other area(s) of head pain, or no occipital involvement. Children with abnormal neurologic examinations were excluded. We assessed location as a predictor of whether neuroimaging was ordered and whether intracranial pathology was found. Analyses were performed with cohort study tools in Stata/SE 13.0 (StataCorp, College Station, TX). A total of 308 patients were included. Median age was 12 years (32 months-18 years), and 57% were female. Headaches were solely occipital in 7% and occipital-plus in 14%. Patients with occipital head pain were more likely to undergo neuroimaging than those without occipital involvement (solely occipital: 95%, relative risk [RR] 10.5, 95% confidence interval [CI] 1.4-77.3; occipital-plus: 88%, RR 3.7, 95% CI 1.5-9.2; no occipital pain: 63%, referent). Occipital pain alone or with other locations was not significantly associated with radiographic evidence of clinically significant intracranial pathology. Children with occipital headache are more likely to undergo neuroimaging. In the absence of concerning features on the history and in the setting of a normal neurologic examination, neuroimaging can be deferred in most pediatric patients when occipital pain is present. © 2017 American Academy of Neurology.

2015-01-01

Deaf individuals have more cardiovascular risks than the general population that are believed to be related to their cardiovascular health knowledge disparities. This phenomenological study describes where 20 deaf sign language-using adolescents from Rochester, New York, many who possess many positive characteristics to support their health literacy, learn cardiovascular health information and their lived experiences accessing health information. The goal is to ultimately use this information to improve the delivery of cardiovascular health education to this population and other deaf adolescents at a higher risk for weak health literacy. Deaf bilingual researchers interviewed deaf adolescents, transcribed and coded the data, and described the findings. Five major sources of cardiovascular health information were identified including family, health education teachers, healthcare providers, printed materials, and informal sources. Despite possessing advantageous characteristics contributing to stronger health literacy, study participants described significant challenges with accessing health information from each source. They also demonstrated inconsistencies in their cardiovascular health knowledge, especially regarding heart attack, stroke, and cholesterol. These findings suggest a great need for additional public funding to research deaf adolescents’ informal health-related learning, develop accessible and culturally appropriate health surveys and health education programming, improve interpreter education, and disseminate information through social media.

Recent evidence suggests that, compared with hearing people, deaf people have enhanced visual attention to simple stimuli viewed in the parafovea and periphery. Although a large part of reading involves processing the fixated words in foveal vision, readers also utilize information in parafoveal vision to preprocess upcoming words and decide where to look next. In the study reported here, we investigated whether auditory deprivation affects low-level visual processing during reading by comparing the perceptual span of deaf signers who were skilled and less-skilled readers with the perceptual span of skilled hearing readers. Compared with hearing readers, the two groups of deaf readers had a larger perceptual span than would be expected given their reading ability. These results provide the first evidence that deaf readers' enhanced attentional allocation to the parafovea is used during complex cognitive tasks, such as reading.

2000-03-01

Deaf children of elementary and secondary school age participated in a study designed to examine their understanding of display rules, the principles governing the expression and concealment of emotion in social situations. The results showed that deaf children's knowledge of display rules, as measured by their reported concealment of emotion, was comparable to that of hearing children of the same age. However, deaf children were less likely to report that they would conceal happiness and anger. They were also less likely to produce reasons for concealing emotion and a smaller proportion of their reasons were prosocial, that is, relating to the feelings of others. The results suggest that the understanding of display rules (which function to protect the feelings of other people) may develop more gradually in deaf children raised in a spoken language environment than it does in hearing children.

2015-05-01

Full Text Available Deaf-blindness forces people to live in isolation. At present, there is no existing technological solution enabling two (or many deaf-blind people to communicate remotely among themselves in tactile Sign Language (t-SL. When resorting to t-SL, deaf-blind people can communicate only with people physically present in the same place, because they are required to reciprocally explore their hands to exchange messages. We present a preliminary version of PARLOMA, a novel system to enable remote communication between deaf-blind persons. It is composed of a low-cost depth sensor as the only input device, paired with a robotic hand as the output device. Essentially, any user can perform hand-shapes in front of the depth sensor. The system is able to recognize a set of hand-shapes that are sent over the web and reproduced by an anthropomorphic robotic hand. PARLOMA can work as a “telephone” for deaf-blind people. Hence, it will dramatically improve the quality of life of deaf-blind persons. PARLOMA has been presented and supported by the main Italian deaf-blind association, Lega del Filo d'Oro. End users are involved in the design phase.

Quality of life of deaf and hard of hearing students in Ibadan metropolis, Nigeria.

Mofadeke T Jaiyeola

Full Text Available Quality of Life encompasses an individual's well-being and health, social participation and satisfaction with functional daily living. Disabilities such as deafness can impact on the quality of life with spatial variance to the environment. Deafness causes communicative problems with significant consequences in cognitive, social, and emotional well-being of affected individuals. However, information relating to the quality of life of deaf and hard of hearing individuals, especially students in developing countries like Nigeria, which could be used to design special health-related interventions is sparse. This study examined the quality of life of deaf and hard of hearing students in Ibadan metropolis, Nigeria. One hundred and ten deaf and hard of hearing students participated in this cross-sectional study. Participants were drawn from all four secondary schools for the Deaf in Ibadan metropolis. The 26 item Brief version of the WHO Quality of Life questionnaire was used for data collection. The data was analyzed using descriptive and inferential statistics at statistical significance of p<0.05. Majority (57.8% of the deaf and hard of hearing students had poor quality of life. Attending the special school for the Deaf, upper socio-economic status and age (≥17years are significantly associated with better quality of life. However, gender and age at onset of hearing loss had no significant influence on the quality of life. The Deaf community available in the special school appeared to protect against stigma and discrimination, while also promoting social interactions between deaf and hard of hearing individuals.

Important progress in the fields of molecular genetics (principally) and diagnostic imaging, together with the lack of a consensus protocol for guiding the diagnostic process after confirming deafness by neonatal screening, have led to this new work document drafted by the Spanish Commission for the Early Detection of Child Deafness (Spanish acronym: CODEPEH). This 2015 Recommendations Document, which is based on the most recent scientific evidence, provides guidance to professionals to support them in making decisions regarding aetiological diagnosis. Such diagnosis should be performed without delay and without impeding early intervention. Early identification of the causes of deafness offers many advantages: it prevents unnecessary trouble for the families, reduces health system expenses caused by performing different tests, and provides prognostic information that may guide therapeutic actions.

Neuroimaging of child abuse: A critical review

Directory of Open Access Journals (Sweden)

Heledd eHart

2012-03-01

Full Text Available Childhood maltreatment is a severe stressor that can lead to the development of behaviour problems and affect brain structure and function. This review summarizes the current evidence for the effects of early childhood maltreatment on behavior, cognition and the brain in adults and children. Neuropsychological studies suggest an association between child abuse and deficits in IQ, memory, executive function and emotion discrimination. Structural neuroimaging studies provide evidence for deficits in brain volume, grey and white matter of several regions, most prominently the dorsolateral and ventromedial prefrontal cortex but also hippocampus, amygdala, and corpus callosum. Diffusion tensor imaging studies show evidence for deficits in structural interregional connectivity between these areas, suggesting neural network abnormalities. Functional imaging studies support this evidence by reporting atypical activation in the same brain regions during executive function and emotion processing. There are, however, several limitations of the abuse research literature which are discussed, most prominently the lack of control for co-morbid psychiatric disorders, which make it difficult to disentangle which of the above effects are due to maltreatment, the associated psychiatric conditions or a combination or interaction between both. Overall, the better controlled studies that show a direct correlation between childhood abuse and brain measures suggest that the most prominent deficits associated with early childhood abuse are in the function and structure of lateral and ventromedial fronto-limbic brain areas and networks that mediate behavioural and affect control. Future, large scale multimodal neuroimaging studies in medication-naïve subjects, however, are needed that control for psychiatric co-morbidities in order to elucidate the structural and functional brain sequelae that are associated with early environmental adversity, independently of secondary

Full Text Available Na atualidade, diversas concepções sobre surdez estão presentes na sociedade. Tais concepções, em geral, caracterizam-se pela disputa teórica entre possibilidades comunicativas - oral ou gestual - fundamentadas na importância da apropriação de um código linguístico para o desenvolvimento da linguagem, constitutiva da subjetividade do ser humano. Nesse direcionamento, este estudo objetivou identificar as concepções dos próprios sujeitos surdos a respeito de sua condição. Para coletar os dados da pesquisa utilizou-se um roteiro de entrevista semiestruturado, que foi aplicado a dez participantes surdos, adultos e usuários da Língua Brasileira de Sinais - Libras. As entrevistas foram filmadas, transcritas e submetidas à análise de conteúdo. Os resultados indicam que as concepções de surdez dos surdos constituem uma visão multifacetada sobre essa condição, influenciada pelas relações sociais estabelecidas ao longo de suas trajetórias de vida. Percebeu-se também que o aprendizado da Libras possibilitou aos surdos a própria autoafirmação enquanto ser diferente, com necessidades distintas.At this time, diverse views on deafness are present in society. Such views, in general, are characterized by theoretical disputes between communicative possibilities - either oral or gestural - based on the importance of having appropriated oneself of a language code for the development of language, which is essential in the constitution of subjectivity of human beings. Thus, this study aimed to identify the conceptions of deaf people had about their condition. To collect the data we used semi-structured interviews, applied to ten participants who were deaf adult users of the Brazilian Sign Language - Libras. The interviews were taped, transcribed and subjected to content analysis. The results indicate that the conceptions of deafness constitute a multifaceted view on this condition, influenced by social relations throughout each

2017-01-01

Freely available software, derived from the past 2 decades of neuroimaging research, is significantly more flexible for research purposes than presently available clinical tools. Here, we describe and demonstrate the utility of rapidly deployable analysis software to facilitate trainee-driven translational neuroimaging research. A recipe and video tutorial were created to guide the creation of a NeuroDebian-based virtual computer that conforms to current neuroimaging research standards and can exist within a HIPAA-compliant system. This allows for retrieval of clinical imaging data, conversion to standard file formats, and rapid visualization and quantification of individual patients' cortical and subcortical anatomy. As an example, we apply this pipeline to a pediatric patient's data to illustrate the advantages of research-derived neuroimaging tools in asking quantitative questions "at the bedside." Our goal is to provide a path of entry for trainees to become familiar with common neuroimaging tools and foster an increased interest in translational research.

2008-08-01

Full Text Available The SCARP project is a series of short studies with two aims; firstly to discover more about disciplinary approaches and attitudes to digital curation through ‘immersion’ in selected cases; secondly to apply known good practice, and where possible, identify new lessons from practice in the selected discipline areas. The study summarised here is of the Neuroimaging Group in the University of Edinburgh’s Division of Psychiatry, which plays a leading role in eScience collaborations to improve the infrastructure for neuroimaging data integration and reuse. The Group also aims to address growing data storage and curation needs, given the capabilities afforded by new infrastructure. The study briefly reviews the policy context and current challenges to data integration and sharing in the neuroimaging field. It then describes how curation and preservation risks and opportunities for change were identified throughout the curation lifecycle; and their context appreciated through field study in the research site. The results are consistent with studies of neuroimaging eInfrastructure that emphasise the role of local data sharing and reuse practices. These sustain mutual awareness of datasets and experimental protocols through sharing peer to peer, and among senior researchers and students, enabling continuity in research and flexibility in project work. This “human infrastructure” is taken into account in considering next steps for curation and preservation of the Group’s datasets and a phased approach to supporting data documentation.

Aging is a process associated with a decline in cognitive and motor functions, which can be attributed to neurological changes in the brain. Tai Chi, a multimodal mind-body exercise, can be practiced by people across all ages. Previous research identified effects of Tai Chi practice on delaying cognitive and motor degeneration. Benefits in behavioral performance included improved fine and gross motor skills, postural control, muscle strength, and so forth. Neural plasticity remained in the aging brain implies that Tai Chi-associated benefits may not be limited to the behavioral level. Instead, neurological changes in the human brain play a significant role in corresponding to the behavioral improvement. However, previous studies mainly focused on the effects of behavioral performance, leaving neurological changes largely unknown. This systematic review summarized extant studies that used brain imaging techniques and EEG to examine the effects of Tai Chi on older adults. Eleven articles were eligible for the final review. Three neuroimaging techniques including fMRI ( N = 6), EEG ( N = 4), and MRI ( N = 1), were employed for different study interests. Significant changes were reported on subjects' cortical thickness, functional connectivity and homogeneity of the brain, and executive network neural function after Tai Chi intervention. The findings suggested that Tai Chi intervention give rise to beneficial neurological changes in the human brain. Future research should develop valid and convincing study design by applying neuroimaging techniques to detect effects of Tai Chi intervention on the central nervous system of older adults. By integrating neuroimaging techniques into randomized controlled trials involved with Tai Chi intervention, researchers can extend the current research focus from behavioral domain to neurological level.

Megadolichobasilar anomaly, a dilatant arteriopathy of the basilar artery attributable to chronic arterial hypertension, can cause cranial nerve compression syndromes of the cerebellopontine angle or infarcts of the vertebrobasilar circulation. In this paper, we report on a patient with known megadolichobasilar anomaly and a partially thrombosed fusiform aneurysm of the basilar artery, who presented with acute-onset vertigo and subsequent deafness due to thromboembolic occlusion of the labyrinthine artery. Because of the vascular origin of the patient's symptoms, his vertigo disappeared over time while the deafness persisted.

2009-01-01

Neuroimaging studies of Turner syndrome can advance our understanding of the X chromosome in brain development, and the modulatory influence of endocrine factors. There is increasing evidence from neuroimaging studies that TX individuals have significant differences in the anatomy, function, and metabolism of a number of brain regions; including the parietal lobe; cerebellum, amygdala, hippocampus; and basal ganglia; and perhaps differences in "connectivity" between frontal and parieto-occipital regions. Finally, there is preliminary evidence that genomic imprinting, sex hormones and growth hormone have significant modulatory effects on brain maturation in TS.

Deaf and hard of hearing students' perspectives on bullying and school climate.

Weiner, Mary T; Day, Stefanie J; Galvan, Dennis

2013-01-01

Student perspectives reflect school climate. The study examined perspectives among deaf and hard of hearing students in residential and large day schools regarding bullying, and compared these perspectives with those of a national database of hearing students. The participants were 812 deaf and hard of hearing students in 11 U.S. schools. Data were derived from the Olweus Bullying Questionnaire (Olweus, 2007b), a standardized self-reported survey with multiple-choice questions focusing on different aspects of bullying problems. Significant bullying problems were found in deaf school programs. It appears that deaf and hard of hearing students experience bullying at rates 2-3 times higher than those reported by hearing students. Deaf and hard of hearing students reported that school personnel intervened less often when bullying occurred than was reported in the hearing sample. Results indicate the need for school climate improvement for all students, regardless of hearing status.

Full Text Available The purpose of this study was to investigate the factors influencing the identity deaf adolescents. The study involved 67 deaf adolescents (38 boys and 29 girls aged 16 to 19 students of secondary school. Ninety-three hearing children constituted a comparison group. The structure of identity was explored on the basis of identification references given by the subjects who were to reply in writing, 20 times running, to the question: „Who Am I?” the test, adapted from M. H. Kuhn and T. S. McPartland by Martines and Silvestre (1995 given in written and signed mode.Results showed that the hearing status as well as mode of communication influence the description of personal identity. It was found that deaf adoles­cents used more descriptions especially in the fol­lowing categories: Civil Status, Body and Physical Appearance, Tastes and Activities, Friendship and Relationships, Personal and Social Situation, Negative Personal Traits, and Neutral Personality Traits. Although this study could demonstrate im­pact independent variables on identity, the data raise the need for further, preferably longitudinal, research. This complex phenomenon has to be examined more closely.Combined self-descriptive processes lead to the development of an organized, learned and dynamic identity, and subjective description of an individ­ual has strong emotional consequences for the in­dividual in question.

2017-01-01

The introduction of non-invasive functional neuroimaging techniques such as functional magnetic resonance imaging (fMRI), in the practice of scientific and clinical research can increase our knowledge about the organization of cognitive processes, including language, in normal and reorganization of these cognitive functions in post-stroke aphasia. The article discusses the results of fMRI studies of functional organization of the cortex of a healthy adult's brain in the processing of various voice information as well as the main types of speech reorganization after post-stroke aphasia in different stroke periods. The concepts of 'effective' and 'ineffective' brain plasticity in post-stroke aphasia were considered. It was concluded that there was an urgent need for further comprehensive studies, including neuropsychological testing and several complementary methods of functional neuroimaging, to develop a phased treatment plan and neurorehabilitation of patients with post-stroke aphasia.

The goal is to ultimately use this information to improve the delivery of cardiovascular health education to this population and other deaf adolescents at a higher risk for weak health literacy. Deaf bilingual researchers interviewed deaf adolescents, transcribed and coded the data, and described the findings. Five major sources of cardiovascular health information were identified including family, health education teachers, healthcare providers, printed materials, and informal sources. Despite possessing advantageous characteristics contributing to stronger health literacy, study participants described significant challenges with accessing health information from each source. They also demonstrated inconsistencies in their cardiovascular health knowledge, especially regarding heart attack, stroke, and cholesterol. These findings suggest a great need for additional public funding to research deaf adolescents' informal health-related learning, develop accessible and culturally appropriate health surveys and health education programming, improve interpreter education, and disseminate information through social media. © The Author 2015.

Peper, Martin; Herpers, Martin; Spreer, Joachim; Hennig, Jürgen; Zentner, Josef

2006-06-01

This article provides a selective overview of the functional neuroimaging literature with an emphasis on emotional activation processes. Emotions are fast and flexible response systems that provide basic tendencies for adaptive action. From the range of involved component functions, we first discuss selected automatic mechanisms that control basic adaptational changes. Second, we illustrate how neuroimaging work has contributed to the mapping of the network components associated with basic emotion families (fear, anger, disgust, happiness), and secondary dimensional concepts that organise the meaning space for subjective experience and verbal labels (emotional valence, activity/intensity, approach/withdrawal, etc.). Third, results and methodological difficulties are discussed in view of own neuroimaging experiments that investigated the component functions involved in emotional learning. The amygdala, prefrontal cortex, and striatum form a network of reciprocal connections that show topographically distinct patterns of activity as a correlate of up and down regulation processes during an emotional episode. Emotional modulations of other brain systems have attracted recent research interests. Emotional neuroimaging calls for more representative designs that highlight the modulatory influences of regulation strategies and socio-cultural factors responsible for inhibitory control and extinction. We conclude by emphasising the relevance of the temporal process dynamics of emotional activations that may provide improved prediction of individual differences in emotionality.

The integration of research on neuroimaging and pharmacogenetics holds promise for improving treatment for neuropsychiatric conditions. Neuroimaging may provide a more sensitive early measure of treatment response in genetically defined patient groups, and could facilitate development of novel therapies based on an improved understanding of pathogenic mechanisms underlying pharmacogenetic associations. This review summarizes progress in efforts to incorporate neuroimaging into genetics and treatment research on major psychiatric disorders, such as schizophrenia, major depressive disorder, bipolar disorder, attention-deficit/hyperactivity disorder, and addiction. Methodological challenges include: performing genetic analyses in small study populations used in imaging studies; inclusion of patients with psychiatric comorbidities; and the extensive variability across studies in neuroimaging protocols, neurobehavioral task probes, and analytic strategies. Moreover, few studies use pharmacogenetic designs that permit testing of genotype × drug effects. As a result of these limitations, few findings have been fully replicated. Future studies that pre-screen participants for genetic variants selected a priori based on drug metabolism and targets have the greatest potential to advance the science and practice of psychiatric treatment.

Quality of Life encompasses an individual's well-being and health, social participation and satisfaction with functional daily living. Disabilities such as deafness can impact on the quality of life with spatial variance to the environment. Deafness causes communicative problems with significant consequences in cognitive, social, and emotional well-being of affected individuals. However, information relating to the quality of life of deaf and hard of hearing individuals, especially students in developing countries like Nigeria, which could be used to design special health-related interventions is sparse. This study examined the quality of life of deaf and hard of hearing students in Ibadan metropolis, Nigeria. One hundred and ten deaf and hard of hearing students participated in this cross-sectional study. Participants were drawn from all four secondary schools for the Deaf in Ibadan metropolis. The 26 item Brief version of the WHO Quality of Life questionnaire was used for data collection. The data was analyzed using descriptive and inferential statistics at statistical significance of pdeaf and hard of hearing students had poor quality of life. Attending the special school for the Deaf, upper socio-economic status and age (≥17years) are significantly associated with better quality of life. However, gender and age at onset of hearing loss had no significant influence on the quality of life. The Deaf community available in the special school appeared to protect against stigma and discrimination, while also promoting social interactions between deaf and hard of hearing individuals.

Other subjects, other school? Strategies and practices in the context of specific schools for the deaf

Full Text Available The deaf community has recursively searched for specific schools for the deaf because it is a space where you could find safety and resistance conditions. Through this article, it seeks to understand how the assumptions that support the school institution are directed, given the nearness with the movements for the deaf. To accomplish this approach, we used excerpts from interviews with deaf, teachers and students from different specifically schools for the deaf of the State of Rio Grande do Sul. The studies of the post-structuralist concern provided the theoretical tools that enabled the analysis. Through this research, it became clear how the deaf community falls within the school, making the assumptions of cultural capital legitimized in the school for the deaf. Nevertheless, it was possible to look at how the processes of discipline inherent in the educational institution happen the same way in the school for the deaf, even though it was taken by the deaf as the site of redemption and as its largest trench.

Bridging the Gap Between DeafBlind Minds: interactional and social foundations of intention-attribution in the Seattle DeafBlind community

Full Text Available This article is concerned with social and interactional processes that simplify pragmatic acts of intention attribution. The empirical focus is a series of interactions among DeafBlind people in Seattle, Washington, where pointing signs are used to individuate objects of reference in the im-mediate environment. Most members of this community are born deaf and slowly become blind. They come to Seattle using Visual American Sign Language, which has emerged and developed in a field organized around visual modes of access. However, as vision deteriorates, links be-tween deictic signs and the present, remembered, or imagined environment erode in idiosyncratic ways across the community of language-users, and it becomes increasingly difficult for partici-pants to converge on objects of reference. In the past, DeafBlind people have addressed this problem by relying on sighted interpreters. Under the influence of the recent pro-tactile movement, they have turned instead to one another to find new solutions to their referential prob-lems. Drawing on analyses of 120 hours of videorecorded interaction and language-use, detailed fieldnotes collected during twelve months of sustained anthropological fieldwork, and more than 15 years of involvement in this community in a range of capacities, I show how DeafBlind peo-ple are generating new and reciprocal modes of access to their environment, and how this pro-cess is aligning language with context in novel ways. I propose two mechanisms that can account for this process: deictic integration and embedding in the social field. I argue that together, these interactional and social mechanisms yield a deictic system set to retrieve a restricted range of values from the extra-linguistic context, thereby attenuating the cognitive demands of intention-attribution and narrowing the gap between DeafBlind minds.

Bilingual proposal in deaf education: educational practices in literacy process

2016-12-01

Full Text Available The teaching and use of the LIBRAS, in the deaf people education are indispensable for their development, building of their identity, autonomy, beside the communication with the world. The acquisition of the Portuguese Language is part of the regular school curriculum, and its command provides a relationship between language and society, which is mostly formed by hearing and users of this language. There is a concern related to the deaf people education, especially in literacy phase, which consequently extends through all the regular schooling, where the most part of the deaf students are finishing the high school without knowing how to read and/or produce in Portuguese Language. This problem affects the social development of these subjects, since the Portuguese Language is still required as if it were the deaf mother tongue, not respecting his/her culture, that has LIBRAS as their first language. The object of this research it to verify the methods and techniques in the deaf people literacy process and seek for other models, based on bilingual theory, ensuring the acquisition of LIBRAS, as a natural language and the teaching of Portuguese Language in a second language methodology, so that, in fact, the acquisition of reading and writing skills to materialize.

Persistence of deaf students in science, technology, engineering, and mathematics undergraduate programs

Science.gov (United States)

Marchut, Amber E.

Diversifying the student population and workforce under science, technology, engineering, and mathematics (STEM) is a necessity if innovations and creativity are to expand. There has not been a lot of literature regarding Deaf students in STEM especially regarding understanding how they persist in STEM undergraduate programs to successfully become STEM Bachelor of Science degree recipients. This study addresses the literature gap by investigating six students' experiences as they navigate their STEM undergraduate programs. The investigation uses narrative inquiry methodology and grounded theory method through the lens of Critical Race Theory and Critical Deaf Theory. Using videotaped interviews and observations, their experiences are highlighted using narratives portraying them as individuals surviving in a society that tends to perceive being deaf as a deficit that needs to be treated or cured. The data analysis also resulted in a conceptual model providing a description of how they persist. The crucial aspect of the conceptual model is the participants learned how to manage being deaf in a hearing-dominated society so they can reach their aspirations. The essential blocks for the persistence and managing their identities as deaf undergraduate STEMs include working harder, relying on familial support, and affirming themselves. Through the narratives and conceptual model of the six Deaf STEM undergraduates, the goal is to contribute to literature to promote a better understanding of the persistence of Deaf students, members of a marginalized group, as they pursue their dreams.

2016-08-01

Requirement for deaf mobile applications need to be analysed to ensure the disabilities need are instilled into the mobile applications developed for them. Universal design is understandable to comply every user needs, however specific disability is argued by the authors to have different need and requirements. These differences are among the reasons for these applications being developed to target for a specific group of people, however they are less usable and later abandoned. This study focuses on deriving requirements that are needed by the deaf in their mobile applications that are meant specifically for them. Studies on previous literature was conducted it can be concluded that graphic, text, multimedia and sign language interpreter are among mostly required features to be included in their mobile application to ensure the applications are usable for this community.

Full Text Available This paper presents an investigation on deaf students' interests in spending their leisure times. We design a questionnaire and distribute among all deaf students who are enrolled in high schools in two provinces of Iran. The questionnaire consists of three parts, in the first part, we ask female and male deaf students about their interests in various entertainment activities in Likert scale. In terms of gender, we find out that walking inside or outside house is number one favorite exercise for female students while male students mostly prefer to walk on the streets. Although male students prefer to go biking or running activities, female students prefer to go for picnic or similar activities. This could be due to limitations on female for running or biking inside cities. While going to picnic with members of family or friends is the third popular activity for male students, stretching exercises is third most popular activity among female students. Breathing exercise is the fourth most popular activity among both male and female students. The second part of the survey is associated with the barriers for having no exercise among deaf students. According to our survey, while lack of good attention from public and ordinary people on exercising deaf students is believed to be number one barrier among male students, female students blame lack of transportation facilities as the most important barrier. However, both female and male students believe these two items are the most important factors preventing them to exercise. Lack of awareness for exercising deaf students and lack of good recreational facilities are the third most important barriers among male and female students. The last part of the survey attempted to detect important entertainment activities. Watching TV, entertaining with mobile devices, chatting with friends and watching DVD or movies were the most important items influencing deaf students' free times.DOI: 10.5267/j.msl.2012

Arnold, P; Murray, C

1998-07-01

The memory of 11 deaf and 11 hearing British Sign Language users and 11 hearing nonsigners for pictures of faces of and verbalizable objects was measured using the game Concentration. The three groups performed at the same level for the objects. In contrast the deaf signers were better for faces than the hearing signers, who in turn were superior to the hearing nonsigners, who were the worst. Three hypotheses were made: That there would be no significant difference in terms of the number of attempts between the three groups on the verbalizable object task, that the hearing and deaf signers would demonstrate superior performance to that of the hearing nonsigners on the matching faces task, and that the hearing and deaf signers would exhibit similar performance levels on the matching faces task. The first two hypotheses were supported, but the third was not. Deaf signers were found to be superior for memory for faces to hearing signers and hearing nonsigners. Possible explanations for the findings are discussed, including the possibility that deafness and the long use of sign language have additive effects.

1995-01-01

Bengkala is an Indonesian village located on the north shore of Bali that has existed for over 700 years. Currently, 2.2% of the 2185 people in this village have profound congenital deafness. In response to the high incidence of deafness, the people of Bengkala have developed a village specific sign language which is used by many of the hearing and deaf people. Deafness in Bengkala is congenital, sensorineural, non-syndromal, and caused by a fully penetrant autosomal recessive mutation at the DFNB3 locus. The frequency of the DFNB3 mutation is estimated to be 9.4% among hearing people who have a 17.2% chance of being heterozygous for DFNB3. PMID:7616538
