    2011-02-01

    The present study was undertaken to provide data on the Bender-Gestalt test for children aged 5 to 11 in Turkey. Although it is well documented that sociocultural factors are important in cognitive evaluations, the effects of type of school and differing educational opportunities provided by these schools on the Bender-Gestalt test have not been previously investigated. The aim of the present study was to investigate the effect of age, sex, and school type on Bender-Gestalt performance. The test was individually administered to 484 children between the ages of 5 and 11 years. The children were enrolled in either public or private schools. Koppitz's Developmental Scoring System was utilized. The results indicated that older children performed with fewer errors. Girls performed with fewer errors than boys. Finally, as expected, private school children outperformed their public school peers. The results are discussed with respect to the importance of taking into account various educational factors in utilizing commonly used tests.

    1977-12-01

    The Developmental Test of Visual-motor Integration (Beery) and the Bender-Gestalt test (Bender) were administered to 44 second-grade children. Developmental age scores (Koppitz scoring) and age equivalents (Beery) were compared. The correlation of .43 between Bender (Koppitz scoring) and Beery scores was moderate but statistically significant. A t test for dependent groups indicated a significant difference between the means on the Bender and Beery tests. These results confirm that neither test should be utilized as the sole indicator of visual-motor perception.

    1992-11-01

    The Bender Gestalt test of visuomotor coordination was applied to a sample of Iranian children (N = 1,600) aged between 6.0 years and 10 years and 11 months attending grades 1 through 5 of 16 public primary schools in Shiraz city, southern Iran. The administration of the test and its scoring followed the standard procedures recommended by Koppitz. The reliability of the test in its new context was investigated through readministering it to a group of 60 children after four weeks, the r being .77. The validity of the test was established by comparing scores of children at different age levels and by correlating test results with marks obtained in two sets of examinations, results of Goodenough Harris Draw-A-Person Test and indices of parental education and occupation. The results are mostly in the expected direction and indicate that the Bender Gestalt test may be used as a simple measure of cognitive-intellectual development in Iran. Observed differences between Iranian norms and those of Koppitz (1963, 1975) for American children are briefly discussed and explained.

  20. The Southern California Sensory Integration Tests (Ayres) and the Bender Gestalt: a correlative study.

    Kimball, J G

    1977-01-01

    The Southern California Sensory Integration Tests (SCSIT) and the Bender Gestalt are two measures used to evaluate children with suspected perceptual-motor deficits. Since these tests are used primarily by two groups of professionals, occupational therapists and psychologists, it was thought that studying the correlations between these two tests might help psychologists to know which children needed to be referred to an occupational therapist for sensory integrative evaluation, and might help the occupational therapist to understand the psychologist's use of the Bender Gestalt. The use of the Bender by the occupational therapist as a screening device for sensory integrative dysfunction was also investigated. The SCSIT and Bender were given to 26 children with suspected sensory integrative dysfunction. Scores on the Bender were found to be predictive of grouped scores on the Form and Space Perception and Praxis-Tactile sections of the SCSIT, but not of the Postural and Bilateral Integration section. It was concluded that when the Bender is used as a screening device for sensory integrative dysfunction, some measure of postural mechanisms must be included. Correlations between the Bender and individual tests of the SCSIT were also studied.

    2011-12-01

    Full Text Available Research with new versions of the Bender Gestalt Test (TGB has hardly attracted attention to the researchers of the Hispanic world, onsidering that this test is one of the most widely used psychological assessments. This study evaluates the construct validity of the modified version of TGB for children, elative to sustainedattention assessed by the Caras Test. Both tests were applied to 90 children, aged between 5 and 8, in standardized conditions. The esults indicate that the shared variance between the two measures is zero, even when applied disattenuated correlations for measurement error; also, no non-linear patterns were detected between the two variables. These correlations were consistent in the total sample and among subgroups of children. We discuss these results with respect to the limits of validity of this modified version of TGB in the Spanish language.

    The Bender-Gestalt and the Developmental Test of Visual-motor Integration were administered to two groups of 40 children each, ages 7 through 10 yr. Developmental age scores (Koppitz scoring) and age equivalents (Revised Beery manual) were obtained. Children screened for learning disabilities were selected for one group and children enrolled in regular classrooms were selected for another group. The correlation of .74 between the Bender and Beery test scores was high and statistically significant for the learning-disabled group. The correlation of .36 was low though statistically significant for the regular students, which suggests the groups performed differently on the tests. A significant mean difference of 9 mo. was noted between the Bender and Beery scores.

    2007-12-01

    The present study was undertaken to provide preliminary data for norms on the Bender-Gestalt Test for 253 children ages 5 yr., 5 mo. to 11 yr., 10 mo. in Turkey. The Koppitz Developmental Scoring System gave mean error scores of 4.2 (SD = 3.3) for girls and 3.6 (SD = 3.0) for boys. The mean error scores obtained by all age groups are presented and compared with other cross-cultural data. These scores decreased across age groups, supporting Bender's maturational hypothesis of the test. The present sample performed at a higher developmental level than the Koppitz normative sample for the 5- and 6-year age groups, while means for other age groups were similar to the original U.S. norms. That this pattern is supported in other cross-cultural studies is discussed as well as the importance of developing local norms for visual spatial tests.

    This study assesses the test-retest reliability of the revised Advanced Psychodiagnostic Interpretation (API) scoring system for the Bender Gestalt Test (BGT). The API system identifies 207 possible distortions in a BGT protocol. Test-retest reliability for 40 schizophrenic patients tested twice with a mean interval of 6.4 years (SD=3.8 years) was good, ranging from .71 to .80. Further reliability and validity studies are needed to further demonstrate the effectiveness of the system.

    César Ayax Merino Soto

    2011-01-01

    Full Text Available This study is looking for evidences of reliability, for the Qualification Qua- litative System (Brannigan y Brunner, 2002 applied to the Bender Gestalt Test – Modified. The participants were 86 children, divided in two groups: pre- school and school; and three students who scored the designs in both groups. The analysis was done in the final grade and the item. The results pointed to the good levels of results of external reliability and internal consistence in the pre- school group, while these levels were scored in the school group. These differences establish the relation between these two aspects of measurement error and the emphasis in an appropriate training of measurements that require the examiner’s judgments. We discussed our results considering the potential utility of this relative version of the Bender Gestalt Test for the clinical practice and investigation as well.

    1983-11-01

    Administered the Bender-Gestalt (BG) and Minnesota Percepto-Diagnostic Test (MPD) to 69 first-grade children prior to administration of the California Achievement Test (CAT). Order of administration for the BG and MPD was counterbalanced to control for practice effects. Correlations (rs) were computed between the 9 CAT subtests and scores from the BG and MPD. The DD score from the MPD correlated significantly with all 9 CAT subtests. The SpCD score from the MPD correlated significantly with 6 of the 9 CAT subtests. The BG Koppitz score correlated significantly with 6 of the 9 CAT subtests. Both the DD and SpCD scores showed a significantly higher negative r with Reading Vocabulary, Total Reading, and Arithmetic Computation than the BG. Furthermore, both types of MPD scores showed a much higher average r with the 9 CAT subtests than was evident for the BG. These findings suggest that DD and SpCD scores from the MPD provide a more sensitive measure of deficits in visual-motor perception than the Koppitz score from the BG.

    Brito, G N; Santos, T R

    1996-11-01

    Norms for two modalities (normal and stress) of the Bender Gestalt test were developed for the neuropsychological assessment of children in the greater Rio de Janeiro area. For each modality, a measure of performance, a measure of speed and a measure of emotional disturbance were obtained. A total of 398 children (199 males and 199 females), 5 to 15 years old, who were attending a public school in Niterói were the subjects of this study. Analysis of the data revealed that age, but not sex, had a significant effect on performance, but not on speed, in both modalities such that older children made fewer errors than younger children. Also, the number of emotional indicators significantly decreased with age. Additionally, boys needed more time to complete the normal modality than girls, and showed a higher number of emotional indicators in both modalities. The Bender test was found to be valid in the sense that children who had failed at least one grade in school performed worse than those who had not. The number of emotional indicators was shown to be valid since it was significantly correlated with factors such as hyperactivity-conduct problem, and independent functioning, and inattention of the Composite Teacher Rating Scale (Brito GNO and Pinto RCA (1991). Journal of Clinical and Experimental Neuropsychology, 13: 417-418). We conclude that the Bender test is valid for use in schoolchildren, and the number of emotional indicators is valid as an index of psychopathology, but sex and age should be considered when using the norms in Brazil.

    computed tomography and the Bender Gestalt Test are some of the tests used routinely for the assessment of alleged offenders referred under Sections 77 and 78 of the Criminal Procedure Act 51 of 1977. An exploratory retrospective study was conducted at the Free State Psychiatric Complex. The aim of this study was to identify the extent to which the Bender Gestalt Test results and the computed tomography scans are associated with outcomes in the assessment of competency to stand trial and criminal responsibility in individuals referred to the Free State Psychiatric Complex (FSPC) observation unit. This was a cross-sectional study and the entire population of patients admitted in 2013 was included in the study. The clinical and demographic data were obtained from patient files. The majority of participants were black, males, single and unemployed. The most common diagnosis was schizophrenia. The current study showed no statistically significant association between the Bender Gestalt Test Hain's scores and the outcome of criminal responsibility and competency to stand trial. Similarly, the study also showed no statistically significant association between the presence of a brain lesion and the outcome of criminal responsibility and competency to stand trial. It was also concluded that as CT scans are expensive, patients should be referred for that service only when there is a clear clinical indication to do so.

    1978-10-01

    Examined the length of time required by retarded adults to complete the Bender-Gestalt test with a sample of 241 test administrations. In order to provide for normative comparisons among retarded adults, descriptive data are presented on the Bender reproduction times of adults in three AAMD ranges of retardation based on WAIS IQs and two ranges based on Stanford-Binet IQs. Negative correlations were found between the length of Bender times and the degree of retardation. The duration of Bender times was correlated positively with the number of errors in reproduction as measured by the Koppitz developmental scoring system.

    2006-02-01

    This study investigated the relationships of visuomotor constructs as measured by the Bender-Gestalt II with the subtests of the WISC-III. A factor analysis included the standardized Copy and Recall scores of the Bender-Gestalt II and subtest scores of the WISC-III. The Copy score was predicted to load on measures of visual and spatial thinking and the Recall score on a short-term memory factor. The results of a principal components analysis suggest a four-factor solution with the Bender-Gestalt II Copy score loading on a visual and spatial thinking factor primarily with WISC-III Perceptual Organization subtests. The Recall score loaded on a visual and spatial thinking factor as well as a short-term memory factor with the WISC-III Digit Span subtest. The results suggest the Bender-Gestalt II Copy subtest shared commonality with the visual and spatial tasks given the similarity in the visuomotor demands of each test and was less influenced by processing speed or cultural knowledge than other tests on the visual and spatial thinking factor. Also, results suggest Bender-Gestalt II Recall measures elements of both visual and spatial thinking as well as aspects of short-term memory and memory retrieval. Clinical guidelines for co-administration and underlying processing demands are discussed.

    The test-retest reliability of the Bender-Gestalt Test was investigated for 157 second graders from two middle-class schools. The test-retest interval ranged from 11 days through 15 days. Testing was conducted in accordance with the Koppitz procedure, but errors of distortion, rotation, integration, and preservation were determined separately. The total time required to reproduce the designs were also recorded. The reliability estimate for the Koppitz score was generally satisfactory, but the estimates obtained for the four separate error categories and total working time were substantially smaller.

    2002-12-01

    To investigate the short-term visual memory ability of children and adolescents with severe psychiatric disorders, 82 child and adolescent inpatients and day hospital patients in a state psychiatric hospital were administered the Bender Gestalt Test as part of a psychological assessment and then asked to reproduce the designs from memory. No significant differences were found between groups on either the Bender Gestalt Recall, or the WISC-III IQs and the Digit Span and Symbol Search subtests for Psychotic Disorders (Schizophrenia, Schizoaffective Disorder, Psychosis Not Otherwise Specified), Attention Deficit Hyperactivity Disorder, Mood Disorders or Mood Disorders with co-morbid Attention Deficit Hyperactivity Disorder. The Coding subtest scores of the Psychotic Disorders group were significantly lower than the ADHD group. Analyses showed that the Bender Gestalt Recall was significantly related to age. Performance IQ, and sex. The results were discussed in terms of both the poor cognitive functioning of children and adolescents with persistent, severe mental illness, and the importance of developmental level when using the Bender Gestalt Recall as a rough measure of short-term visual memory.

    We evaluated the concurrent validity of the revised Bender-Gestalt emotional indicators (Koppitz, 1975) among three groups of children in the 7- to 10-year age range: adjustment disorder, behavior disorder, and normal control. The concurrent validity of the emotional indicators total score was demonstrated. Notably, with the developmental level controlled, both clinical groups produced significantly more emotional indicators than the control group, although the two clinical groups could not be differentiated. Nominal-data analyses of the 13 individual emotional indicators indicated that three specific indicators (confused order, large size, boxed figures) possessed validity as pathognomonic signs. We discuss issues concerning the use of the emotional indicators in clinical practice.

    1995-01-01

    Data are presented to assess the use of the Koppitz scoring system for the Bender-Gestalt Test in a sample (N = 87) of behaviorally and emotionally disturbed adolescents. Results suggested that age was modestly related to Koppitz Developmental scores, an indication that visual-motor skills continue to develop beyond age 11. Scores were related to spatial perception skills as measured on the WISC-R. Gender, primary psychiatric diagnosis, educational tests, and MMPI scores were not related to Bender performance. Findings are discussed in terms of a need for additional research into the utility of the Bender as a measure of visual-motor skills in adolescents.

    The present study was designed to evaluate the relative efficacy of two different scoring systems (Koppitz, 1975; Lacks, 1984) for use in evaluating Bender-Gestalt performance by adolescents. Normative data are presented for the two scoring systems with a sample of "normal" controls (N = 150), emotionally disturbed (N = 140), and mentally retarded/neurologically impaired adolescents (N = 47), aged 12-17. Results suggested that age and psychopathology were not related to the quality of the Bender-Gestalt reproductions of these subjects. An inverse relationship was found between cognitive ability and visual motor skills. Data obtained from these samples of adolescents showed a high degree of consistency between the scoring systems, which suggests that either scoring procedure is suitable for evaluating the Bender-Gestalt performance of adolescents.

    1998-12-01

    The validity of the Koppitz Developmental scoring system in identifying organic impairment among functionally impaired adolescents was challenged in the current study. It was proposed that there are two distinct subtypes of errors in this system: those that are valid indicators of organic impairment (Category A) and those which are not but occur as a function of specific emotional factors (Category B). 46 male adolescents with a primary diagnosis of Conduct Disorder, Oppositional Defiant Disorder, or Attention-Deficit Hyperactivity Disorder were administered the Bender-Gestalt once using the standard order of administration and once in reverse order. It was hypothesized that more errors would be committed on cards presented later than those presented earlier in sequence for Category B but not Category A errors. Analysis provided partial support for this hypothesis.

The results failed to support the use of Hutt's (1985) Psychopathology Scale and Adolescent Configuration in differentiating the "normal" and emotionally disturbed groups, but did support their use in differentiating the MR/NI group from the other two. The Hutt scores also were found to be related inversely to age and IQ. By contrast, the Koppitz scores differentiated the three groups from each other and were not related significantly to IQ. The results supported limited use of Koppitz's (1975) Emotional Indicators as a "sign" approach to brief screening for emotional disturbance in adolescents.

    Rossini, E D

    1993-06-01

    The concurrent validity of Hutt's (1977) empirical psychopathology scale of the Bender Visual-Motor Gestalt Test was evaluated among three groups of younger school-aged children within the 7-to-10- year age range (M = 109.1): adjustment disordered, conduct disordered, and nonclinical controls (n = 40/group). Excellent interscorer reliability was achieved with approximately 2 hr of self-study of the scoring manual. Although the conduct-disordered group was significantly more immature on Koppitz' Developmental Scoring System, there were no significant differences among groups on the psychopathology scale when visual-motor development was covaried (M = 50.5). This was an unexpected result, given Hutt's initial validation study among school-aged children. The psychopathology scale was not inferred to be valid among adolescents in the only known concurrent validation study. Pending supportive validation research, the psychopathology scale should not be employed in the clinical assessment of younger school-aged children.

    1999-06-01

    The purpose of this paper was to extend research on Koppitz's Developmental Scoring System to Italian samples. Specific attention has been given to the study of errors for the single designs to assess the relationship of these errors with total errors and to assess the designs' varying difficulty. A second purpose was to study possible cultural influences between different Italian regions. According to Koppitz (1975) research findings support that the rate of development in visuomotor perception differs among children of various ethnic groups. Subjects were 538 boys and 527 girls enrolled in the regular kindergarten and elementary schools in Italy. Detailed analyses were carried out on total mean errors and mean errors for each design. Mean errors decrease across age groups; that is, perceptuomotor integration is improved for older children. No significant differences were found between Northern and Southern Italy.

    Full Text Available Abstract Background The 'double-diamond copy' task is a simple paper and pencil test part of the Bender-Gestalt Test and the Mini Mental State Examination (MMSE. Although it is a widely used test, its method of scoring is crude and its psychometric properties are not adequately known. The aim of the present study was to develop a sensitive and reliable method of administration and scoring. Methods The study sample included 93 normal control subjects (53 women and 40 men aged 35.87 ± 12.62 and 127 patients suffering from schizophrenia (54 women and 73 men aged 34.07 ± 9.83. Results The scoring method was based on the frequencies of responses of healthy controls and proved to be relatively reliable with Cronbach's α equal to 0.61, test-retest correlation coefficient equal to 0.41 and inter-rater reliability equal to 0.52. The factor analysis produced two indices and six subscales of the Standardised Copy of Pentagons Test (SCPT. The total score as well as most of the individual items and subscales distinguished between controls and patients. The discriminant function correctly classified 63.44% of controls and 75.59% of patients. Discussion The SCPT seems to be a satisfactory, reliable and valid instrument, which is easy to administer, suitable for use in non-organic psychiatric patients and demands minimal time. Further research is necessary to test its psychometric properties and its usefulness and applications as a neuropsychological test.

    2000-06-01

    Performance of 66 children, 30 with and 36 without learning disabilities, in four ways using the Bender Visual-motor Gestalt Test was compared. First, the test with the standard Koppitz scoring procedure, second with the Canter Background Interference Procedure sheet using the standard Koppitz scoring procedure; third, the Bender test on a standard sheet of paper using Canter scoring procedure; and fourth, the Canter Background Interference Procedure (BIP) sheet using the Canter scoring procedure. The effectiveness of the Canter procedure was examined when scored with an age-appropriate normative scoring system. This was accomplished by combining the Canter BIP interference sheet with the Koppitz scoring system. The children ranged in age from 6 to 10 years. Using discriminant analysis, all four methods correctly categorized statistically significant percentages of both types of students but there was a significant difference on the Canter BIP sheet using the Canter scoring procedure. This procedure classified students with the least absolute number and percentage of either false negatives or false positives when compared with the other three methods, suggesting that using this scoring method with the Bender Gestalt may be better for identifying younger children with learning disabilities.

  15. Validez incremental del Test Gestáltico de Bender Modificado, en niños que inician el primer grado

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available The Bender Gestalt Test (BGT has a long history in psychological assessment and several scoring systems have been developed for it. One of them is the Brannigan and Brunner’s Qualitative Scoring System (QSS, developed for the modified version of this test that uses six of the nine original designs (BGT Modified. However, there is limited psychometric evidence for the Spanish speaking population about the usefulness of this measure in an academic screening battery. The purpose of this study is to report evidence of incremental validity of this abbreviated version regarding school achievement, within a group of 101 five year olds entering the first grade of primary education. We applied a hierarchical multiple regression controlling for the effects of fluid intelligence and pre-academic skills, compared to the criteria of school grades. We found that the inclusion of BGT Modified brings significant unique variance in school grades, and is a more powerful predictor than intelligence. Our results support the use of BGT Modified in a brief battery of screening in identifying children at risk for poor school performance

    1992-01-01

    This study investigated the relationship between the pattern of impairment on test scores of the neurologically impaired children and proximity to an inactive toxic waste disposal site. Subjects (N = 147) were students, ages 6-16, classified as neurologically impaired. Seventy-six who lived within six miles of the site served as the experimental group and 71 who did not live near a site comprised the control group. Research was based on existing data available through the Child Study Team evaluation process. Attention was given to the ACID cluster of the WISC-R, the Arithmetic and Reading subtests on the WRAT, and the Koppitz scores of the Bender Visual Motor Gestalt Test. No significant difference was found between the experimental and control groups. Sex differences within the experimental group were not significant. Time of exposure and patterning of scores in the experimental group were investigated. Time had a significant main effect on WISC-R Arithmetic and Digit Span subtests, the ACID cluster and the Bender Test for the total group. Main effect for sex was significant for the WISC-R Information subtest. An interaction effect was found to be significant on the WRAT Arithmetic subtest WRAT. The longer the girls lived within the site area the lower they scored on the WISC-R Information subtest and the WRAT Arithmetic subtest. The variable exposure (interaction of distance and time) was related to lower scores on the WISC-R Arithmetic and Digit Span subtest. A two-way interaction was found on the WRAT Arithmetic subtest. The longer the females were exposed to the waste site area, the lower they scored on the WRAT Arithmetic subtest. A comparison of those children in the site area from birth and those in the area three years prior to the evaluation was done. A significant main effect was found for the Bender Gestalt.

  8. Visuomotor perception in children with attention deficit hyperactivity disorder--combined type.

    Raggio, D J

    1999-04-01

    Children with Attention Deficit Hyperactivity Disorder--Combined Type (ADHD-CT) defined by behavioral characteristics of inattention, impulsivity, and hyperactivity including weaknesses in fine motor coordination and poor motor inhibition frequently exhibit poor handwriting and penmanship. Performance of children on visuomotor tasks is further complicated, as most studies have not excluded children with specific learning disabilities who are known to do poorly on these tests. This study was designed to examine the performance of children diagnosed with this disorder, without learning disabilities on visuomotor tasks. 26 preadolescent patients were administered a battery of tests that included the Bender-Gestalt, Conners' Parent Rating Scale, Continuous Performance Task, and Wide Range Achievement Test-Third Edition Scores on the Bender-Gestalt test averaged significantly lower than Koppitz normative data. This study lends support to the hypothesis that ADHD-CT children without learning disabilities exhibit deficits on tasks requiring visuomotor perception.

    1979-03-01

    Visual matching and visual exploration were examined in 7 normal subjects and 20 brain-damaged patients with drawing impairment measured by the Bender Gestalt Visual-Motor Test. Right brain-damaged patients made significantly more errors of rotation and integration than left brain-damaged patients. Selecteded Bender figures were also used as stimuli for both visual matching and visual exploration tests. The ability to match Bender figures was found to be impaired in right but not left brain-damaged patients. All patients showed eye movement and fixation patterns different from those normals. Patients essentially had more fixations and shorter fixation durations. Significant intercorrelations were found between the total Bender Gestalt score and visual matching and visual exploration scores. These findings indicate that visual matching and visual exploration measures can be used to evaluate perceptual impairment in individuals who do not have adequate motor responses or where impaired motor responses may confound interpretations about visual cognitive impairment.

    Twenty-seven children with acute leukemia were studied in order to detect the subsequent neurologic complications due to chemotherapy and radiation therapy. Twenty-four patients with ALL received central nervous system prophylaxis including cranial irradiation. The methods of evaluation consisted of electroencephalogram (EEG), computed tomography of the head (CT scan), soft neurological sign, intelligence quotient (IQ) and Bender Gestalt test. The patients with relapse showed severe abnormalities in various kinds of examinations. Younger children at diagnosis were associated with a higher abnormality rate of soft neurological signs and Bender Gestalt test. Factors which were found to be closely associated with a lower IQ score included younger children at diagnosis and longer duration of remission time. These results indicate the need for caution for the dosage of cranial irradiation for younger patients in CNS prophylaxis, and improvement of a lower IQ score in long-term survivors requires further investigation as to the appropriate intellectual environment for their development after remission.

    Criterion-related validity of Raven's Progressive Matrices (RPM) was investigated using a sample of 107 deaf residential adolescents. Data collection involved retrieval of psychoeducational test scores (RPM; WISC-R Performance IQ; VMI-R; Bender-Gestalt; and SAT-HI Reading Comprehension, Spelling, and Language) from student files. Concurrent validity between the Standard Progressive Matrices (SPM) and WISC-R PIQ was established, with significant (p .001) correlations of .598 (using WISC-R deaf norms) and .616 (using WISC-R hearing norms). Predictive validity was supported by significant correlations between the SPM and SAT-HI Reading Comprehension, Spelling, and Language scores.

    Full Text Available There are structural and functional associations between hormone systems and central nervous system. Disturbances of thyroid hormone should cause neuropsychiatric symptoms. It is seen that there might be indistinct brain dysfunction symptoms in patients with euthyroid Hashimato disease. His neuropsychiatric profile assessed by examination and a battery included neuropsychiatric tests. Cancellation Test, Stroop Test TBAG form, Auditory Verbal Learning Test, Bender Gestalt Visual Motor Test and WISC-R tests were carried to patient. Failure in executive functioning and complex attention was determined in patient. In Bender Gestalt Visual Motor Test, perceiving of visual stimulus, visual motor coordination and predicating of perceived stimulus with motor functioning were significantly disordered. WISC-R subtests were also supporting these findings. Thyroid hormones and the problems with thyroid gland may cause some disturbances in neuropsychological profile. It should be helpful to see thyroid functioning tests in patients which referred with neuropsychological symptoms. (Jo­ur­nal of Cur­rent Pe­di­at­rics 2013; 11: 146-9

    2012-04-01

    Test scores of 119 students, attending either a public four-year college or a technical school, were related to their proportionality and detail drawing scores on the Memory for Designs Test. In regression models, the ETS Maze Tracing, Eliot-Price Mental Rotations, and Bender-Gestalt tests were consistent predictors of proportionality scores, with the latter two tests uniquely related to these. The ETS Shapes Memory Test and the Form Board Test were the strongest predictors for detail accuracy scores. The Shapes test predicted proportionality when the CTY Visual Memory Test BB was excluded. The models then provided support for the hypothesis that drawing designs from memory, a critical skill in drawing, regardless of whether one focuses on accuracy for proportionality scores or for detail scores, is jointly related to the measures of recognition, production, and traditional spatial ability measures. This study identified multifaceted skills in drawing from memory.

    Full Text Available Abstract Visual-motor maturity and executive functions are closely related in the child development process. This study aimed to investigate the relation between visual-motor abilities and executive functions in 83 healthy children between 7 and 10 years old. The tools used were the Bender Gestalt Visual-Motor Test - Gradual Scoring System (B-GSS, Wisconsin Card Sorting Test (WCST, Raven's Progressive Matrices (RPM, and Rey-Osterrieth Complex Figure (ROCF. The correlation between the B-GSS and WCST scores was significantly negative (r = -.23, p < .033, while ROCF variables, such as Total Memory and Total Copy, had a moderate, significant correlation with total B-GSS score (r = -.55, p < .001; r = -.44, p < .001, respectively. The results empirically show the relation between executive functions and visual-motor maturity and are discussed in face of developmental neuropsychology.

    1994-12-01

    32 boys, between the ages of 8 and 13 years, were identified on four teachers' and parents' rating scales (including the diagnostic criteria of the DSM-III for ADD) as showing attention deficits and hyperactivity (ADD + H; n = 10), attention deficits without hyperactivity (ADD-H; n = 11), or without ADD (attention deficits controls; n = 11). All subjects were administered Bender's Visual-motor Gestalt test and the Written Language Assessment. The ADD + H children produced significantly more errors on the Bender-Gestalt test, and both groups with attention deficits had lower (poorer) scores on most of the written language subtests. Results were interpreted as providing evidence that these children possessed significant limitations in their writing, copying, and composition.

    Full Text Available Abstract: Although the relationship between perceptual motor skills and attention is reported in the literature, few studies have empirically explored this association. Thus, the objective of this study was to investigate the relationship between these constructs, using the Bender-Gestalt Test: Gradual Scoring System (B-SPG and the Psychological Battery for Attention Assessment (BPA. The participants were 320 children from four public schools in a city located in the South of the state of Minas Gerais, with ages ranging from seven to 10 years (M = 8.39, SD = 1.10 and 196 (55.9 % female. The results showed negative, moderate and significant correlations between the total scores of the instruments, indicating the relationship between the constructs. Although the data has confirmed the existence of a relationship between perceptual motor skills and attention, further studies with samples from other regions are necessary.

    We describe a prospective study of histidinaemia. Probands and siblings (n = 21) with typical histidinaemia in 16 families were ascertained by newborn screening; diagnosis was confirmed by appropriate investigations in each subject; none had been treated by low histidine diet. The median age of subjects with histidinaemia was 9.5 y (mean 10.0, SD 3.5, range 6-18). Age-matched sib-pairs and their mothers were studied. IQ scores (Full Scale, Verbal and Performance Scores), Visual-Motor Integration Performance (Bender Gestalt and Koppitz scores), Wide Range Achievement Test (Reading and Mathematics), school performance, and psychological history were evaluated, as well as the medical history (pregnancy, delivery, neonatal, post-natal development). Findings were correlated with biochemical phenotype. CNS development in histidinaemic subjects (mean and distribution of scores) was normal; outlier values did not correlate with degree of histidinaemia. We can conclude that histidinaemia detected by newborn screening is a non-disadaptive phenotype.

    Full Text Available Aim: The aim of this study was to evaluate the cognitive and visual perceptive functions in children with childhood epilepsy with occipital paroxysms (CEOP. Material and Method: Hospital charts of children ages 1 to 18 years who admitted to pediatric neurology out-patient clinic between 2009 and 2010 were reviewed. Twenty one children with a diagnosis of CEOP were identified. Sixteen of these children who accepted to include the study were evaluated with neuropsychological tests. Results: Two of five patients who were evaluated with Denver developmental screening test were found to have lower scores than their reference standards. Remaining 11 patients were evaluated with Wechsler Scales of Intelligence tests, 4 were mildly mental retarded and 1 had null intelligence. Eleven patients were also evaluated with Bender Gestalt Visual Motor Test and 7of them had disturbances in visual perception. Reading speed and writing norm tests were applied to 9 literate patients and 7 of them showed slower reading ability and writing ability was found worse in 6 patients. Discussion: The absence of neurological and neuropsylogical deficits has long been considered as a prerequisite for diagnosis of benign childhood partial epilepsies. However, only a few studies describing the cognitive profile of patients with CEOP have been published. The present study has demonstrated that the patients with CEOP had varying degree of cognitive dysfunction and disturbance in visual perception. In order to provide appropriate intervention, cognitive functions should be assessed in children with CEOP.

    Attention, learning, and perceptual problems have been reported at various degrees and rates in neurofibromatosis type 1 (NF1). We aimed to define the cognitive profiles frequently associated with NF1. Children and adolescents with NF1 (n=58) were tested using Wechsler Intelligence Scales for Children-Revised (WISC-R), Judgment of Line Orientation, and Bender Visual-Motor Gestalt tests. Comparison groups were unaffected siblings of NF1 patients (n=20), children with attention deficit and hyperactivity disorder (ADHD, n=40), and normal children (n=40). No difference was found between familial or sporadic NF1 cases. Seventeen/58 (29%) of NF1 cases had a full scale IQ80 (n=27) scored lower in WISC-R subtests measuring visual perception when compared to a healthy control group of similar intelligence, and lower in arithmetic but better in Bender-Gestalt and Judgment of Line Orientation tests when compared to an ADHD group of similar intelligence. These results indicate a high prevalence of mental retardation in a clinical NF1 series. NF1 patients who have normal intelligence may have impaired visual perception, but their visual perceptual problems are less than in ADHD. The tendency of unaffected siblings of NF1 patients to have mildly but consistently low test scores compared to healthy controls needs to be studied further for underlying genetic or environmental factors.

  7. Centration-distortion error: a criterion of perceptual dysfunction.

    Science.gov (United States)

    Mecke, V

    This was a study to determine whether centration, as a perceptual process, could be a criterion for differentiating between neurologically impaired and emotionally disturbed children. Centration was defined by Piaget as a prolonged involuntary attachment of a sensory modality to one part of a field, causing perceptual errors of exaggerations and distortions. It is hypothesized that centration would affect motor behavior, producing effects on drawing tasks characterized by separation of designs or their parts, coincident with distortions of the figures drawn. The neurologically impaired children were identified as having primary difficulties with perception whereas the emotionally disturbed children would have primary difficulties with intellection. The centration-distortion error would characterize the drawing of the neurologically impaired but not those of the emotionally disturbed children. A sample of 44 children was selected, each with EEG records, psychological tests and psychiatric interviews used as differential criteria for the groups. Eleven children were diagnosed as having minimal brain damage, 33 as emotionally disturbed. Three psychologists scored the Bender Gestalt tests, blind, for indicators of brain injury and emotional disturbance as defined by Koppitz' criteria, and for the centration-distortion error. The hypothesis was upheld at the .001 level of confidence, validating an earlier pilot study.

  8. The effects of frontal EMG biofeedback and progressive relaxation upon hyperactivity and its behavioral concomitants.

    Braud, L W

    Hyperactive children (N = 15) and nonhyperactive children (N = 15) were compared. Hyperactive children were found to possess significantly higher (p less than .002) muscular tension levels and, in addition, presented more behavioral problems and had lower test scores. Both electromyographic (EMG) biofeedback and progressive relaxation exercises were successful in the significant reduction of muscular tension, hyperactivity, distractability, irritability, impulsivity, explosiveness, aggressivity, and emotionality in hyperactive children. The greatest improvement was seen in the area of "emotionality-aggression" (irritability, explosiveness, impulsivity, low frustration tolerance, aggresion). No differences were seen in the EMG improvement of drug and nondrug hyperactive children; both made progress under these self-control techniques. However, nondrug children made greater improvements in the behavioral area. Both EMG biofeedback and progressive relaxation resulted in improvements on the test scores of hyperactive subjects (Bender-Gestalt, Visual Sequential Memory, Digit Span, Coding). The therapy would appear to be improved by the inclusion of mental relaxation, concentration, meditation, and mind-blanking exercises for mental control.

  9. Demographic features and neuropsychological correlates in a cohort of 200 patients with vascular cognitive decline due to cerebral small vessel disease

    Directory of Open Access Journals (Sweden)

    Thomas Gregor Issac

    2016-01-01

    Full Text Available Introduction: Vascular dementia is the second most common form of dementia and is potentially reversible. Small vessel disease (SVD closely mimics degenerative dementia in view of its sub-acute onset and progressive course. Therefore, unlike large vessel disease, Hachinski Ischemic scale score may not always reflect vascular cognitive decline resulting in diagnostic and therapeutic confusions. Therefore, there is a need for detailed neuropsychological assessment for various cognitive domains for early identification of vascular cognitive decline as it carries a very good long term prognosis for cognitive morbidity, unlike degenerative dementias. Patients and Methods: This prospective study involves thorough domain based neuropsychological assessment of patients with a radiological diagnosis of SVD involving the following parameters-digit forward and backward, category fluency, color trails, stick test, logical memory test, and bender gestalt test. Magnetic resonance imaging scans done using 3-tesla machines and SVD graded using Fazekas visual scale. Results: The mean Hachinskis score was less sensitive for differentiating vascular dementia from degenerative dementia. However, the domain based neuropsychological scores were highly sensitive showing statistically significant impairment in all 6 domains tested and compared with Fazekas 1-3 grades in imaging. Discussion and Conclusion: This study aimed at establishing an early diagnosis of vascular mild cognitive impairment using domain wise neuropsychological testing and correlating it with radiological scores. Hachinskis score is more sensitive for large vessel disease in view of acute onset and step-like progression as against steady progression in SVD. However, domain-wise testing was highly sensitive in identifying early cognitive impairment in patients with SVD, and early therapeutic interventions are highly rewarding.

  16. Interrater reliability of the Koppitz Developmental Scoring method in the clinical evaluation of the single case.

    Svensson, P W; Hill, M A

    1990-04-01

    Using the Koppitz method, Bender-Gestalt protocols of three patients (8-12 yr.), representing three commonly occurring disorders, and of one normal child were evaluated by 12 raters of varying experience with this system. Raters were asked to make provisional diagnoses based on Bender protocols alone, and these were compared with actual clinical diagnoses. Despite significant interrater reliability of Koppitz Total Developmental Scores and emotional indices, no significant agreement was found in subscores or in diagnoses made, although the effect of raters' experience was noted. Results suggest that the type of dysfunction present is a factor in raters' reliability. Results are seen, however, to support the potential of the Bender-Gestalt for use in relatively subtle diagnosis of children and highlight the differentiation of "organic" versus "developmental" factors as an area for further study.

In fact, we present two distinct characterisations, which give rise to the same relation: an operational one based on a De Nicola-Hennessy-like testing modality which we call should-testing, and a denotational one based on a refined notion of failures. One of the distinguishing characteristics of the should-t...

    The Hubbert theory of oil depletion, which states that oil production in large regions follows a bell-shaped curve over time, has been cited as a method to predict the future of global oil production. However, the assumptions of the Hubbert method have never been rigorously tested with a large, publicly available data set. In this paper, three assumptions of the modern Hubbert theory are tested using data from 139 oil producing regions. These regions are sub-national (United States state-level, United States regional-level), national, and multi-national (subcontinental and continental) in scale. We test the assumption that oil production follows a bell-shaped curve by generating best-fitting curves for each region using six models and comparing the quality of fit across models. We also test the assumptions that production over time in a region tends to be symmetric, and that production is more bell-shaped in larger regions than in smaller regions. (author)

    1992-01-01

    Auxiliary Power Unit (APU) fuel (hydrazine) tanks have had to be removed from the Columbia Shuttle (OV-102) because they have been in service for 11 years, which is the limit of their useful life. As part of an effort to determine whether the useful life of the fuel tanks can be extended, examination of the ethylene propylene rubber (EPR) diaphragm and the metal from one of the APU tanks is required. The JSC Propulsion and Power Division has requested White Sands Test Facility (WSTF) to examine the EPR diaphragm thoroughly and the metal casing generally from one tank. The objective is to examine the EPR diaphragm for signs of degradation that may limit the life of its function in the APU propellant tank. The metal casing will also be examined for signs of surface corrosion.

  20. Boilerplate Test Article (BTA) Modal Test Correlation

    2017-01-01

    Modal testing of the Boilerplate Test Article (BTA) was performed to obtain data to determine the accuracy of the BTA LS- DYNA model in determining the structural response. The BTA is a full-scale steel and aluminum test article that is representative of the Orion Crew Module (CM), with similar outer-mold-line geometry, mass properties, and some similar structural features, including an internal pressure vessel connected to a backshell and heatshield via longerons, Retention and Release (R&R) brackets, and an aft ring. The structural design of the Orion CM is being developed based on LS-DYNA water landing simulations. To obtain data to evaluate the accuracy of LS-DYNA water impact landing simulations, a series of BTA water impacts was conducted at NASA Langley Research Center (LaRC). Discrepancies between test and simulation data are attributed to three causes:(1) Test data variability and uncertainty, (2) LS-DYNA water model and fluid-structure coupling approximations; and (3) LS-DYNA structural modeling approximations. Two activities have been undertaken to assess the accuracy of the BTA LS-DYNA structural model separately from the fluid-structure coupling portion of the water landing simulations: 1) modal testing, and 2) static load testing. The results from the static load tests are documented in a separate report. For the modal test series, the following tests were performed: (1) BTA Fully-Assembled Model Test, (2) BTA Backshell Removed Modal Test, (3) Standalone Heatshield Modal Test, (4) Standalone Windward Backshell Panel Modal Test; and (5) Standalone Leeward Backshell Panel Modal Test. This report documents findings from correlation of modal test data with LS-DYNA modal analysis results. The following figures illustrate the correlation of the modal frequencies. Where multiple closely spaced modes have been identified, the points representing the upper and lower frequencies are shown connected by a dotted line.

  7. Tractor accelerated test on test rig

    Directory of Open Access Journals (Sweden)

    M. Mattetti

    2013-09-01

    Full Text Available The experimental tests performed to validate a tractor prototype before its production, need a substantial financial and time commitment. The tests could be reduced using accelerated tests able to reproduce on the structural part of the tractor, the same damage produced on the tractor during real life in a reduced time. These tests were usually performed reproducing a particular harsh condition a defined number of times, as for example using a bumpy road on track to carry out the test in any weather condition. Using these procedures the loads applied on the tractor structure are different with respect to those obtained during the real use, with the risk to apply loads hard to find in reality. Recently it has been demonstrated how, using the methodologies designed for cars, it is possible to also expedite the structural tests for tractors. In particular, automotive proving grounds were recently successfully used with tractors to perform accelerated structural tests able to reproduce the real use of the machine with an acceleration factor higher than that obtained with the traditional methods. However, the acceleration factor obtained with a tractor on proving grounds is in any case reduced due to the reduced speed of the tractors with respect to cars. In this context, the goal of the paper is to show the development of a methodology to perform an accelerated structural test on a medium power tractor using a 4 post test rig. In particular, several proving ground testing conditions have been performed to measure the loads on the tractor. The loads obtained were then edited to remove the not damaging portion of signals, and finally the loads obtained were reproduced in a 4 post test rig. The methodology proposed could be a valid alternative to the use of a proving ground to reproduce accelerated structural tests on tractors.

With the help of software testing we can verify or validate the software product. Normally testing will be done after development of software but we can perform the software testing at the time of development process also. This paper will give you a brief introduction about Automated API Testing Tool. This tool of testing will reduce lots of headache after the whole development of software. It saves time as well as money. Such type of testing is helpful in the Industries & Colleges also.

  15. Who fails lantern tests?

    Science.gov (United States)

    Cole, B L; Vingrys, A J

    1983-05-01

    A battery of clinical colour vision tests was given to a group of 100 observers with abnormal colour vision who were also tested on the Farnsworth lantern and the Holmes-Wright lanterns types A and B. It was found that clinical colour vision tests are imperfect predictors of lantern test performance. However, observers classified as having a 'severe' colour vision defect were found to fail the lantern tests but only one half to two-thirds of those who fail the lantern tests can be identified in this way. It is not possible to identify with certainty any of the people likely to pass the lantern tests: about one-third to two-thirds of observers classified as being mildly affected fail the lantern tests. The Farnsworth D-15 and City University tests were found to be the best predictors of lantern test performance but other tests such as the Nagel anomaloscope, the H-16, L'Anthony's desaturated test can also be used. The lack of a strong correlation between clinical tests and the recognition of the small coloured stimuli presented by the lantern tests suggests that clinical tests do not test the same aspect of colour vision that is important to the recognition of signal lights. For this reason lantern tests should be retained for occupational testing of colour vision.

  3. Localizing Test Power Consumption for Scan Testing

    Institute of Scientific and Technical Information of China (English)

    XIANG Dong; LI Kai-wei

    2005-01-01

    A two stage scan architecture is proposed to do low powerand low test application cost scan testing. The first stage includes multiple scan chains, where each scan chain is driven by a primary input. Each scan flip-flop in the multiple scan chains drives a group of scan flip-flops. The scan flip-flop in the multiple scan chain and the scan flipflop driven by it are assigned the same values for all test vectors. Scan flip-flops in the multiple scan chains and those in the second stage use separate clock signals, but the design for testability technqiue needs only one clock. The proposed scan architecture localizes test power consumption to the multiple scan chains during test application. Test signals assigned to scan flip-flops in the multiple scan chains are applied to the scan flip-flops in the second stage after the test vector has been applied to the multiple scan chains. This technique can make test power consumption very small.

  15. Materials Testing and Automation

    Science.gov (United States)

    Cooper, Wayne D.; Zweigoron, Ronald B.

    1980-07-01

    The advent of automation in materials testing has been in large part responsible for recent radical changes in the materials testing field: Tests virtually impossible to perform without a computer have become more straightforward to conduct. In addition, standardized tests may be performed with enhanced efficiency and repeatability. A typical automated system is described in terms of its primary subsystems — an analog station, a digital computer, and a processor interface. The processor interface links the analog functions with the digital computer; it includes data acquisition, command function generation, and test control functions. Features of automated testing are described with emphasis on calculated variable control, control of a variable that is computed by the processor and cannot be read directly from a transducer. Three calculated variable tests are described: a yield surface probe test, a thermomechanical fatigue test, and a constant-stress-intensity range crack-growth test. Future developments are discussed.

  5. Gas Test Loop Booster Fuel Hydraulic Testing

    Energy Technology Data Exchange (ETDEWEB)

    Gas Test Loop Hydraulic Testing Staff

    2006-09-01

    The Gas Test Loop (GTL) project is for the design of an adaptation to the Advanced Test Reactor (ATR) to create a fast-flux test space where fuels and materials for advanced reactor concepts can undergo irradiation testing. Incident to that design, it was found necessary to make use of special booster fuel to enhance the neutron flux in the reactor lobe in which the Gas Test Loop will be installed. Because the booster fuel is of a different composition and configuration from standard ATR fuel, it is necessary to qualify the booster fuel for use in the ATR. Part of that qualification is the determination that required thermal hydraulic criteria will be met under routine operation and under selected accident scenarios. The Hydraulic Testing task in the GTL project facilitates that determination by measuring flow coefficients (pressure drops) over various regions of the booster fuel over a range of primary coolant flow rates. A high-fidelity model of the NW lobe of the ATR with associated flow baffle, in-pile-tube, and below-core flow channels was designed, constructed and located in the Idaho State University Thermal Fluids Laboratory. A circulation loop was designed and constructed by the university to provide reactor-relevant water flow rates to the test system. Models of the four booster fuel elements required for GTL operation were fabricated from aluminum (no uranium or means of heating) and placed in the flow channel. One of these was instrumented with Pitot tubes to measure flow velocities in the channels between the three booster fuel plates and between the innermost and outermost plates and the side walls of the flow annulus. Flow coefficients in the range of 4 to 6.5 were determined from the measurements made for the upper and middle parts of the booster fuel elements. The flow coefficient for the lower end of the booster fuel and the sub-core flow channel was lower at 2.3.

Various sperm function tests are proposed and endorsed by different researchers in addition to the routine evaluation of fertility. These tests detect function of a certain part of spermatozoon and give insight on the events in fertilization of the oocyte. The sperms need to get nutrition from the seminal plasma in the form of fructose and citrate (this can be assessed by fructose qualitative and quantitative estimation, citrate estimation.

    A passive system can provide engineered safety features enhancing safety system reliability and plant simplicity. Toshiba has conducted the test Program to demonstrate the feasibility of the SBWR passive safety system using a full-height, integral system test facility GIRAFFE. The test facility GIRAFFE models the SBWR in full height to correctly present the gravity driving head forces with a 1/400 volume scale. The GIRAFFE test Program includes the certification tests of the passive containment cooling system (PCCS) to remove the post-accident decay heat and the gravity driven cooling system (GDCS) to replenish the reactor coolant inventory during a LOCA. The test results have confirmed the PCCS and GDCS design and in addition, have demonstrated the operation of the pCCS with the presence of a lighter-than-steam noncondensable as well as with the presence of a heavier-than-steam, noncondensable. The GIRAFFE test Program has also provided the database to qualify a best estimate thermal-hydraulic computer code TRAC. The post test analysis results have shown that TRAC can accurately predict the PCCS heat removal Performance and the containment pressure response to a LOCA. This paper summarizes the GIRAFFE test results to investigate post-LOCA PCCS heat removal performance and post-test analysis using TRAC.

    2001-05-31

    One of the 3 technologies currently being developed for the Savannah River Salt Waste Processing Program is the Small-Tank Tetraphenylborate Process (STTP). This process uses sodium tetraphenylborate to precipitate and remove radioactive Cs from the waste and monosodium titanate to sorb and remove radioactive Sr and actinides. ORNL is demonstrating this process at the 1:4000 scale using a 20-liter continuous-flow stirred tank reactor (CSTR) system. The primary goal of Test 4 was to verify that the STTP process could achieve and maintain the necessary Cs decontamination while TPB was actively decomposing. Even with TPB being decomposed by the off-normal conditions of this test, the decontaimination factor for {sup 137}Cs obtained for the filtrate from the Slurry Concentrating Tank ranged from 47,000 to 646,000, exceeding the WAC standard.

    As capacitor manufacturers race to meet the needs of the hybrid-electric vehicle (HEV) of the future, many trade-offs at the system level as well as the component level must be considered. Even though the ultra-capacitor has the spot light for recent research and development (R&D) for HEVs, the electrostatic capacitor is also the subject of R&D (for HEVs as well as wireless communications). The Department of Energy has funded the Oak Ridge National Laboratory's Power Electronic and Electric Machinery Research Center to develop an automated test to aid in the independent testing of prototype electrostatic capacitors. This paper describes the design and development of such a stand.

    2012-01-01

    While usability evaluation is critical to designing usable websites, traditional usability testing can be both expensive and time consuming. The advent of crowdsourcing platforms such as Amazon Mechanical Turk and CrowdFlower offer an intriguing new avenue for performing remote usability testing with potentially many users, quick turn-around, and significant cost savings. To investigate the potential of such crowdsourced usability testing, we conducted two similar (though not completely parallel) usability studies which evaluated a graduate school's website: one via a traditional usability lab setting, and the other using crowdsourcing. While we find crowdsourcing exhibits some notable limitations in comparison to the traditional lab environment, its applicability and value for usability testing is clearly evidenced. We discuss both methodological differences for crowdsourced usability testing, as well as empirical contrasts to results from more traditional, face-to-face usability testing.

  3. Indentation load relaxation test

    Energy Technology Data Exchange (ETDEWEB)

    Hannula, S.P.; Stone, D.; Li, C.Y. (Cornell Univ., Ithaca, NY (USA))

    Most of the models that are used to describe the nonelastic behavior of materials utilize stress-strain rate relations which can be obtained by a load relaxation test. The conventional load relaxation test, however, cannot be performed if the volume of the material to be tested is very small. For such applications the indentation type of test offers an attractive means of obtaining data necessary for materials characterization. In this work the feasibility of the indentation load relaxation test is studied. Experimental techniques are described together with results on Al, Cu and 316 SS. These results are compared to those of conventional uniaxial load relaxation tests, and the conversion of the load-indentation rate data into the stress-strain rate data is discussed.

  4. On Testing Constraint Programs

    CERN Document Server

    Lazaar, Nadjib; Yahia, Lebbah

    2010-01-01

    The success of several constraint-based modeling languages such as OPL, ZINC, or COMET, appeals for better software engineering practices, particularly in the testing phase. This paper introduces a testing framework enabling automated test case generation for constraint programming. We propose a general framework of constraint program development which supposes that a first declarative and simple constraint model is available from the problem specifications analysis. Then, this model is refined using classical techniques such as constraint reformulation, surrogate and global constraint addition, or symmetry-breaking to form an improved constraint model that must be thoroughly tested before being used to address real-sized problems. We think that most of the faults are introduced in this refinement step and propose a process which takes the first declarative model as an oracle for detecting non-conformities. We derive practical test purposes from this process to generate automatically test data that exhibit no...

    2013-01-01

    As part of the Nuclear Systems Office Fission Surface Power Technology Demonstration Unit (TDU) project, a reactor simulator test loop (RxSim) was design & built to perform integrated testing of the TDU components. In particular, the objectives of RxSim testing was to verify the operation of the core simulator, the instrumentation and control system, and the ground support gas and vacuum test equipment. In addition, it was decided to include a thermal test of a cold trap purification design and a pump performance test at pump voltages up to 150 V since the targeted mass flow rate of 1.75 kg/s was not obtained in the RxSim at the originally constrained voltage of 120 V. This paper summarizes RxSim testing. The gas and vacuum ground support test equipment performed effectively in NaK fill, loop pressurization, and NaK drain operations. The instrumentation and control system effectively controlled loop temperature and flow rates or pump voltage to targeted settings. The cold trap design was able to obtain the targeted cold temperature of 480 K. An outlet temperature of 636 K was obtained which was lower than the predicted 750 K but 156 K higher than the cold temperature indicating the design provided some heat regeneration. The annular linear induction pump (ALIP) tested was able to produce a maximum flow rate of 1.53 kg/s at 800 K when operated at 150 V and 53 Hz.

  7. LHC synchronization test successful

    CERN Multimedia

    The synchronization of the LHC's clockwise beam transfer system and the rest of CERN's accelerator chain was successfully achieved last weekend. Tests began on Friday 8 August when a single bunch of a few particles was taken down the transfer line from the SPS accelerator to the LHC. After a period of optimization, one bunch was kicked up from the transfer line into the LHC beam pipe and steered about 3 kilometres around the LHC itself on the first attempt. On Saturday, the test was repeated several times to optimize the transfer before the operations group handed the machine back for hardware commissioning to resume on Sunday. The anti-clockwise synchronization systems will be tested over the weekend of 22 August.Picture:http://lhc-injection-test.web.cern.ch/lhc-injection-test/

  8. Test facilities for VINCI®

    Greuel, Dirk; Schäfer, Klaus; Schlechtriem, Stefan

    2013-09-01

    With the replacement of the current upper-stage ESC-A of the Ariane 5 launcher by an enhanced cryogenic upper-stage, ESA's Ariane 5 Midterm Evolution (A5-ME) program aims to raise the launcher's payload capacity in geostationary transfer orbit from 10 to 12 tons, an increase of 20 %. Increasing the in-orbit delivery capability of the A5-ME launcher requires a versatile, high-performance, evolved cryogenic upper-stage engine suitable for delivering multiple payloads to all kinds of orbits, ranging from low earth orbit to geostationary transfer orbit with increased perigee. In order to meet these requirements the re-ignitable liquid oxygen/liquid hydrogen expander cycle engine VINCI® currently under development is designated to power the future upper stage, featuring a design performance of 180 kN of thrust and 464 s of specific impulse. Since 2010 development tests for the VINCI® engine have been conducted at the test benches P3.2 and P4.1 at DLR test site in Lampoldshausen under the ESA A5-ME program. For the VINCI® combustion chamber development the P3.2 test facility is used, which is the only European thrust chamber test facility. Originally erected for the development of the thrust chamber of the Vulcain engine, in 2003 the test facility was modified that today it is able to simulate vacuum conditions for the ignition and startup of the VINCI® combustion chamber. To maintain the test operations under vacuum conditions over an entire mission life of the VINCI® engine, including re-ignition following long and short coasting phases, between 2000 and 2005 the test facility P4.1 was completely rebuilt into a new high-altitude simulation facility. During the past two P4.1 test campaigns in 2010 and 2011 a series of important milestones were reached in the development of the VINCI® engine. In preparation for future activities within the frame of ESA's A5-ME program DLR has already started the engineering of a stage test facility for the prospective upper stage

    2012-12-01

    Full Text Available Background and Aim: All activities of daily living need to balance control in static and dynamic movements. In recent years, a numerous increase can be seen in the functional balance assessment tools. Functional balance tests emphasize on static and dynamic balance, balance in weight transfer, the equilibrium response to the imbalances, and functional mobility. These standardized and available tests assess performance and require minimal or no equipment and short time to run. Functional balance is prerequisite for the most static and dynamic activities in daily life and needs sufficient interaction between sensory and motor systems. According to the critical role of balance in everyday life, and wide application of functional balance tests in the diagnosis and assessment of patients, a review of the functional balance tests was performed.Methods: The Google Scholar, PubMed, Science Direct, Scopus, Magiran, Iran Medex, and IranDoc databases were reviewed and the reliable and valid tests which were mostly used by Iranian researchers were assessed.Conclusion: It seems that Berg balance scale (BBS have been studied by Iranian and foreign researches more than the other tests. This test has high reliability and validity in elderly and in the most neurological disorders.

    Schoenfeld, Michael P.; Webster, Kenny L.; Pearson, Boise Jon

    2013-01-01

    As part of the Nuclear Systems Office Fission Surface Power Technology Demonstration Unit (TDU) project, a reactor simulator test loop (RxSim) was design & built to perform integrated testing of the TDU components. In particular, the objectives of RxSim testing was to verify the operation of the core simulator, the instrumentation and control system, and the ground support gas and vacuum test equipment. In addition, it was decided to include a thermal test of a cold trap purification design and a pump performance test at pump voltages up to 150 V since the targeted mass flow rate of 1.75 kg/s was not obtained in the RxSim at the originally constrained voltage of 120 V. This paper summarizes RxSim testing. The gas and vacuum ground support test equipment performed effectively in NaK fill, loop pressurization, and NaK drain operations. The instrumentation and control system effectively controlled loop temperature and flow rates or pump voltage to targeted settings. The cold trap design was able to obtain the targeted cold temperature of 480 K. An outlet temperature of 636 K was obtained which was lower than the predicted 750 K but 156 K higher than the cold temperature indicating the design provided some heat regeneration. The annular linear induction pump (ALIP) tested was able to produce a maximum flow rate of 1.53 kg/s at 800 K when operated at 150 V and 53 Hz. Keywords: fission, space power, nuclear, liquid metal, NaK.

    1996-06-01

    In order to support advanced manufacturing, Sandia has acquired the capability to produce plastic prototypes using stereolithography. Currently, these prototypes are used mainly to verify part geometry and ``fit and form`` checks. This project investigates methods for rapidly testing these plastic prototypes, and inferring from prototype test data actual metal part performance and behavior. Performances examined include static load/stress response, and structural dynamic (modal) and vibration behavior. The integration of advanced non-contacting measurement techniques including scanning laser velocimetry, laser holography, and thermoelasticity into testing of these prototypes is described. Photoelastic properties of the epoxy prototypes to reveal full field stress/strain fields are also explored.

    Proprioception, the reception of stimuli within the body that indicates position, is an important mechanism for optimal human performance. People exposed to prolonged bed rest, microgravity, or other deconditioning situations usually experience reduced proprioceptor and kinesthetic stimuli that compromise body balance, posture, and equilibrium. A new proprioceptive test is described that utilizes the computer-driven LIDO isokinetic ergometer. An overview of the computer logic, software, and testing procedure for this proprioceptive test, which can be performed with the arms or legs, is described.

    2004-01-01

    This paper discusses a model-based approach to validate software requirements in agile development processes by simulation and in particular automated testing. The use of models as central development artifact needs to be added to the portfolio of software engineering techniques, to further increase efficiency and flexibility of the development beginning already early in the requirements definition phase. Testing requirements are some of the most important techniques to give feedback and to increase the quality of the result. Therefore testing of artifacts should be introduced as early as possible, even in the requirements definition phase.

    A series of transformer room fire tests are reported to demonstate the shock hazard present when automatic sprinklers operate over energized electrical equipment. Fire protection was provided by standard 0.5 inch pendent automatic sprinklers temperature rated at 135 F and installed to give approximately 150 sq ft per head coverage. A 480 v dry transformer was used in the room to provide a three phase, four wire distribution system. It is shown that the induced currents in the test room during the various tests are relatively small and pose no appreciable personnel shock hazard.

    Full Text Available The most widespread opinion among people who have some connection with software testing is that this activity is an art. In fact, books have been published widely whose titles refer to it as art, role or process. But because software complexity is increasing every year, this paper proposes a new approach, conceiving the test as a science. This is because the processes by which they are applied are the steps of the scientific method: inputs, processes, outputs. The contents of this paper examines the similarities and test characteristics as science.

    In this paper, are presented some possibilities concerning the implementation of a test-driven development as a programming method. Here is offered a different point of view for creation of advanced programming techniques (build tests before programming source with all necessary software tools and modules respectively). Therefore, this nontraditional approach for easier programmer's work through building tests at first is preferable way of software development. This approach allows comparatively simple programming (applied with different object-oriented programming languages as for example JAVA, XML, PYTHON etc.). It is predictable way to develop software tools and to provide help about creating better software that is also easier to maintain. Test-driven programming is able to replace more complicated casual paradigms, used by many programmers.

    The Large Hadron Collider is now entering in its final phase before receiving beam, and the activities at CERN between 2007 and 2008 have shifted from installation work to the commissioning of the technical systems ("hardware commissioning"). Due to the unprecedented complexity of this machine, all the systems are or will be tested as far as possible before the cool-down starts. Systems are firstly tested individually before being globally tested together. The architecture of LHC, which is partitioned into eight cryogenically and electrically independent sectors, allows the commissioning on a sector by sector basis. When a sector reaches nominal cryogenic conditions, commissioning of the magnet powering system to nominal current for all magnets can be performed. This paper briefly describes the different activities to be performed during the powering tests of the superconducting magnet system and presents the scheduling issues raised by co-activities as well as the management of resources.

  11. [Alternatives to animal testing].

    Science.gov (United States)

    Fabre, Isabelle

    2009-11-01

    The use of alternative methods to animal testing are an integral part of the 3Rs concept (refine, reduce, replace) defined by Russel & Burch in 1959. These approaches include in silico methods (databases and computer models), in vitro physicochemical analysis, biological methods using bacteria or isolated cells, reconstructed enzyme systems, and reconstructed tissues. Emerging "omic" methods used in integrated approaches further help to reduce animal use, while stem cells offer promising approaches to toxicologic and pathophysiologic studies, along with organotypic cultures and bio-artificial organs. Only a few alternative methods can so far be used in stand-alone tests as substitutes for animal testing. The best way to use these methods is to integrate them in tiered testing strategies (ITS), in which animals are only used as a last resort.

    This test verifies the FOM's mechanical operation. A 7 x 1 grid of points will be made by moving the FOM in steps of 6.5 from -20 to +19 arcsec relative to the 0 position {-36 to +3 relative to the default NIC3 FOM position of +16 arcsec}. We also have an additional FOM position at the default NIC3 position. These exposures all use the F166N filter. At the end of this sequence we will take F222M exposures at three additional FOM positions, the default position {+16 arcsec relative to the center point of the FOM mechanical range} and +/- 2 arcsec. This is to test for vignetting. Prerequisites for this test are cool down to nominal operating temperature {cold and stable, near the expected final temperature set point, but not necessarily the final temperature set point} and the filter wheel minifunctional and the filter wheel tests {proposals 8944 and 8972}.

  9. Cosmological Tests of Gravity

    CERN Document Server

    Jain, Bhuvnesh

    2010-01-01

    Modifications of general relativity provide an alternative explanation to dark energy for the observed acceleration of the universe. We review recent developments in modified gravity theories, focusing on higher dimensional approaches and chameleon/f(R) theories. We classify these models in terms of the screening mechanisms that enable such theories to approach general relativity on small scales (and thus satisfy solar system constraints). We describe general features of the modified Friedman equation in such theories. The second half of this review describes experimental tests of gravity in light of the new theoretical approaches. We summarize the high precision tests of gravity on laboratory and solar system scales. We describe in some detail tests on astrophysical scales ranging from ~kpc (galaxy scales) to ~Gpc (large-scale structure). These tests rely on the growth and inter-relationship of perturbations in the metric potentials, density and velocity fields which can be measured using gravitational lensi...

    Hereditary dyslipidemias are often underdiagnosed and undertreated, yet with significant health implications, most importantly causing preventable premature cardiovascular diseases. The commonly used clinical criteria to diagnose hereditary lipid disorders are specific but are not very sensitive. Genetic testing may be of value in making accurate diagnosis and improving cascade screening of family members, and potentially, in risk assessment and choice of therapy. This review focuses on using genetic testing in the clinical setting for lipid disorders, particularly familial hypercholesterolemia.

  10. Safer Aviation Materials Tested

    Palaszewski, Bryan A.

    2001-01-01

    A series of thermally stable polymer samples were tested. These materials are called low heat release materials and are designed for aircraft interior decorative materials. The materials are designed to give off a minimum amount of noxious gases when heated, which increases the possibility that people can escape from a burning aircraft. New cabin materials have suitably low heat release so that fire does not spread, toxic chemicals are not given off, and the fire-emergency escape time for crew and passengers is lengthened. These low heat-release materials have a variety of advantages and applications: interiors for ground-based facilities, interiors of space vehicles, and many commercial fire-protection environments. A microscale combustion calorimeter at the Federal Aviation Administration's (FAA) Technical Center tested NASA Langley Research Center materials samples. The calorimeter is shown. A sharp, quantitative, and reproducible heat-release-rate peak is obtained in the microscale heat-release-rate test. The newly tested NASA materials significantly reduced the heat release capacity and total heat release. The thermal stability and flammability behavior of the samples was very good. The new materials demonstrated a factor of 4 reduction in total heat release over ULTEM (a currently used material). This information is provided in the following barchart. In other tests, the materials showed greater than a factor 9 reduction in heat-release capacity over ULTEM. The newly tested materials were developed for low dielectric constant, low color, and good solubility. A scale up of the material samples is needed to determine the repeatability of the performance in larger samples. Larger panels composed of the best candidate materials will be tested in a larger scale FAA Technical Center fire facility. The NASA Glenn Research Center, Langley (Jeff Hinkley), and the FAA Technical Center (Richard Lyon) cooperatively tested these materials for the Accident Mitigation

    2013-01-01

    Full Text Available ISO 10993-4 is an international standard describing the methods of testing of medical devices for interactions with blood for regulatory purpose. The complexity of blood responses to biomaterial surfaces and the variability of blood functions in different individuals and species pose difficulties in standardisation. Moreover, in vivo or in vitro testing, as well as the clinical relevance of certain findings, is still matter of debate. This review deals with the major remaining problems, including a brief explanation of surface interactions with blood, the current ISO 10993 requirements for testing, and the role of in vitro test models. The literature is reviewed on anticoagulation, shear rate, blood-air interfaces, incubation time, and the importance of evaluation of the surface area after blood contact. Two test categories deserve further attention: complement and platelet function, including the effects on platelets from adhesion proteins, venipuncture, and animal derived- blood. The material properties, hydrophilicity, and roughness, as well as reference materials, are discussed. Finally this review calls for completing the acceptance criteria in the ISO standard based on a panel of test results.

  17. Automated Test Case Generation

    CERN Document Server

    CERN. Geneva

    2015-01-01

    I would like to present the concept of automated test case generation. I work on it as part of my PhD and I think it would be interesting also for other people. It is also the topic of a workshop paper that I am introducing in Paris. (abstract below) Please note that the talk itself would be more general and not about the specifics of my PhD, but about the broad field of Automated Test Case Generation. I would introduce the main approaches (combinatorial testing, symbolic execution, adaptive random testing) and their advantages and problems. (oracle problem, combinatorial explosion, ...) Abstract of the paper: Over the last decade code-based test case generation techniques such as combinatorial testing or dynamic symbolic execution have seen growing research popularity. Most algorithms and tool implementations are based on finding assignments for input parameter values in order to maximise the execution branch coverage. Only few of them consider dependencies from outside the Code Under Test’s scope such...

  18. Testing for recombinant erythropoietin.

    Science.gov (United States)

    Delanghe, Joris R; Bollen, Mathieu; Beullens, Monique

    2008-03-01

    Erythropoietin (Epo) is a glycoprotein hormone that promotes the production of red blood cells. Recombinant human Epo (rhEpo) is illicitly used to improve performance in endurance sports. Doping in sports is discouraged by the screening of athletes for rhEpo. Both direct tests (indicating the presence of exogeneous Epo isoforms) and indirect tests (indicating hematological changes induced by exogenous Epo administration) can be used for Epo detection. At present, the test adopted by the World Anti Doping Agency is based on a combination of isoelectric focusing and double immunoblotting, and distinguishes between endogenous and rhEpo. However, the adopted monoclonal anti-Epo antibodies are not monospecific. Therefore, the test can occasionally lead to the false-positive detection of rhEpo (epoetin-beta) in post-exercise, protein-rich urine, or in case of contamination of the sample with microorganisms. An improved preanalytical care may counteract a lot of these problems. Adaptation of the criteria may be helpful to further refine direct Epo testing. Indirect tests have the disadvantage that they require blood instead of urine samples, but they can be applied to detect a broader range of performance improving techniques which are illicitly used in sports.

    The initial goal of this task is to adequately understand the treatment needs of the end user in treating contaminated wastewater. These needs are then incorporated into the evaluation of new treatment technologies for wastewater treatment. Pertinent information is than supplied to the end user so that they can select a preferred process to meet their waste treatment needs. New sorbent materials, ion-exchange materials, or other processes of interest to DOE`s Office of Environmental Restoration (EM-40) will be evaluated initially for the removal of {sup 90}Sr and {sup 137}Cs from groundwater and process wastewater. Laboratory studies will strive to obtain a quantitative understanding of the behavior of these new materials and to evaluate their sorption efficiency in reference to a standard benchmark treatment technique. Testing of the new materials will begin by conducting scoping tests where new treatment materials are compared with standard, commercially available materials in batch shaker tests. Experimental data for the most promising sorbents will then be fit to an equilibrium model so that nuclide sorption can be predicted for variable wastewater composition. Additional testing with actual wastewater will be conducted with two or three of the most effective treatment methods. Once batch testing of a treatment method is completed, dynamic column tests will be performed to validate the equilibrium sorption model and to obtain the defining column operating parameters for scaling up the technology.

    Hughes cryogenic holographic test facility allows for the rapid characterization of optical components and mechanical structures at elevated and reduced temperatures. The facility consists of a 1.6 meter diameter thermal vacuum chamber, vibration isolated experiment test platform, and a holographic camera assembly. Temperatures as low as 12 Kelvin and as high as 350 Kelvin have been demonstrated. Complex aspheric mirrors are tested without the need for auxiliary null lenses and may be tested in either the polished or unpolished state. Structural elements such as optical benches, solar array panels, and spacecraft antennas have been tested. Types of materials tested include beryllium, silicon carbide, aluminum, graphite epoxy, silicon/aluminum matrix material and injection molded plastics. Sizes have ranged from 7 cm X 15 cm to 825 cm X 1125 cm and have weighed as little as 0.2 Kg and as much as 130 Kg. Surface figure changes as little as (lambda) /10 peak-to-valley ((lambda) equals .514 micrometers ) are routinely measured.
