Another look at the effects of the system of multicultural pluralistic assessment

The purpose of this study was (a) to determine if a declassification occurs when estimated learning potential (ELP) is used in reevaluation of special education students and (b) to assess the effects of the use of ELP by multidisciplinary teams. Subjects included 107 black and 13 white students (83 males and 37 females) referred for reevaluation from classes for the mentally retarded. Data analysis consisted of determining the percentage of students who would be classified as mentally retarded according to the main criterion of (a) Wechsler Intelligence Scale for Children-Revised (WISC-R) scores, or (b) ELP scores, or (c) multidisciplinary teams' placement. A chi-square test of independence indicated a significant difference between WISC-R and ELP scores; and between multidisciplinary teams' placement and ELP scores (p<.05). Students already in special education classes for the mentally retarded were not determined to be ineligible for services by multidisciplinary teams, even though 15% of the students would be ineligible for services according to ELP scores.     

Clinical utility of the WISC-R and the French Pictorial Test of Intelligence with native American primary grade children

Cultural bias and the clinical utility of the WISC-R and French Pictorial Test of Intelligence were evaluated using scores of 22 male and 22 female Navajo primary grade children. There were no significant differences in performance on either test according to sex. As expected, the Verbal IQ and Full Scale IQ of the WISC-R and the Deviation IQ of the French provided significantly depressed estimates of ability. A prorated Performance IQ might be the least depressed measure of potential among these children.

使用测试方式对中学生的焦虑水平和认知策略之间的关系进行了研究。结果发现,在7钟认知策略中能力认识、失败归因、命运控制和社会关系4种认知策略在三个级别的焦虑组之间存在显著差异,焦虑水平高的人倾向于使用否定自身能力、选取失败、悲惨宿命论和消极社会关系认知策略。除成就认识外．其他认知策略不存在性别差异,女性倾向于产生低成就认知。     

Use of the Peabody Picture Vocabulary Test with the educationally handicapped

Despite widespread use of the Peabody Picture Vocabulary Test (PPVT) as a measure of intelligence for educationally handicapped students, few studies have related PPVT scores of such students to their scores on the Wechsler Intelligence Scale for Children (WISC). Using 100 public school students consecutively referred for learning difficulties, their mean PPVT IQ (97.75) was found to be consistently and significantly higher than WISC Full Scale IQ (89.65), Verbal IQ (88.68), and Performance IQ (92.73). Correlations between the PPVT IQ and the WISC Full Scale, Verbal, and Performance IQs were .70, .69, and .54, respectively. A tabular summary of previous studies comparing PPVT and WISC IQs is included.     

Stability of scores for the Slosson Full-Range Intelligence Test

The test-retest stability of the Slosson Full-Range Intelligence Test by Algozzine, Eaves, Mann, and Vance was investigated with test scores from a sample of 103 students. With a mean interval of 13.7 mo. and different examiners for each of the two test administrations, the test-retest reliability coefficients for the Full-Range IQ, Verbal Reasoning, Abstract Reasoning, Quantitative Reasoning, and Memory were .93, .85, .80, .80, and .83, respectively. Mean differences from the test-retest scores were not statistically significantly different for any of the scales. Results suggest that Slosson scores are stable over time even when different examiners administer the test.     

The relationship between psychological test results and EEG patterns in healthy children

222 children (112 girls and 110 boys) aged 5–16 years with different types of EEG pattern, selected according to well defined normal criteria in order to exclude cerebral lesion elements, were investigated by current child-psychiatric diagnostic methods, including the Wechsler Intelligence Scale for children (WISC), which gave a mean IQ of 116.5. With two so-called tests of organicity (Bender Gestalt Test and Benton's Revised Visual Retention Test) poor performances indicating brain damage were shown in 22% and 24% of the children respectively. Various EEG patterns showed few significant correlations with the test variables. According to clinical judgement "slight symptoms of cerebral dysfunction" was found in some children, but no correlation appeared between such symptoms and poor performance in the psychological tests. The high frequency of defective scores in the Bender and Benton tests in this selected material of healthy children means that these tests cannot be used in clinical work for diagnosing brain injury in individual children. Nor can they be used to throw light on the clinical significance of the different EEG variables studied.     

Responses of low-IQ students on the learning awareness questionnaire compared to students matched on mental and chronological age

Learning awareness, including semantic content, response strategy, processing strategy, summarization, and memory in the classroom, were examined in students with mental retardation. From urban schools in Japan special high school students with average IQ of 60 (n = 40) and students with normal intellectual capacity matched on mental (n = 40) and chronological age (n = 40) were administered a 16-item Learning Awareness Questionnaire. Students of low IQ on the Tanaka-Binet test obtained lower scores on semantic content and memory strategies than chronological or mental age-matched controls, but not on response and processing. Scores indicated that students of low IQ may be equally aware of learning processes related to response and processing strategies.     

A validation study of a transferred group intelligence test(1)

The purpose of the research was to conduct a validation study of a transferred group intelligence test. The Lorge-Thorndike Intelligence Test, Level A, Form 1 was translated to Hebrew and administered to an Israeli sample comparable to the original norming group. The results obtained were concerned with variability, reliability, validity, item analysis, intercorrelations among subtests, and factor analysis. While few comparisons of the Israeli sample with the original data were made, the validation of the transferred test was examined in the light of other criteria for evaluating a new test. The suitability of the transferred test for Israeli high achievers from high-status families was supported by the results. The major conclusions were: (1) the total mean IQ scores of Israeli students were approximately the same as the American mean; (2) mean raw scores increased with age; (3) relative difficulty of individual items remained stable through translation and administration in Israeli culture, in three out of five subtests; (4) it appears reasonable to suggest that the factor structure of the translated test is consistent with the intent of the original.     

Comparability of IQ scores over time

This study investigates the comparability of IQ scores. Three cohorts (1933/36, 1997/98, 2006) of Estonian students (N = 2173) are compared using the Estonian National Intelligence Test. After 72 years the secular rise of the IQ test scores is.79 SD. The mean .16 SD increase in the last 8 years suggests a rapid increase of the Flynn Effect (FE) in Estonia. The measurement is not strictly invariant, which means that the IQ scores of different cohorts are not directly comparable. Less than perfect comparability of test scores is caused by at least two factors: time between measurements and societal/educational changes between cohorts. As was to be expected, the meaning of subtests and the meaning of the g score have changed over time.     

Relationship between intelligence and vocabulary

This study explored the correlations of scores on the Wechsler Intelligence Scale for Children-III in screening language problems and scores on the three Comprehensive Receptive and Expressive Vocabulary Test subscales. Participants were 243 students ages 6 to 17 years in Grades K-11 who were identified as learning disabled, learning disabled with speech impairment, mentally retarded, and speech impaired. Analysis indicated strong correlations between the two measures, particularly between the CREVT General Vocabulary and WISC-III Verbal IQ (r = .80), WISC-III Verbal Comprehension Index (r =.83), and the Vocabulary subtest (r =.76). These results held across the grades. Supporting earlier studies of relationships of Verbal IQ and Receptive Vocabulary, correlations were lower between participants in Grades K through 2 than those in higher grades on the WISC-III Verbal IQ and the Receptive Vocabulary subtest. An analysis of the accuracy of the WISC-III for classifying students with language problems indicated improvement in classification over chance. These findings suggest that the WISC-III may be an effective screen for language problems.     

Comparison and combination of recall and Background Interference Procedures for the Bender-Gestalt Test with brain-damaged and schizophrenic patients.

The Bender-Gestalt Test was administered under standard, recall, Background Interference Procedure (BIP), and BIP-recall conditions to 20 brain-damaged and 20 schizophrenic male inpatients. Individual recall, BIP, and BIP-recall scores differentiated between the groups prior to controlling for IQ, but only recall and BIP-recall continued to discriminate once IQ was held constant. The use of difference scores corrected for standard copy performance (base level) resulted in improved diagnostic discrimination compared to difference scores alone. However, this procedure also produced a substantial multiple correlation with IQ and a consequent loss of group differentiation for the BIP difference score, while failing to yield an appreciable increase in predictive accuracy over individual scores for recall and BIP-recall. Nonetheless, a significant effect emerged independently of both recall and IQ for the BIP-recall score, suggesting that the BIP hypothesis may have merit within the context of memory functioning.     

Validity of the Wechsler abbreviated scale of intelligence and other very short forms of estimating intellectual functioning

Performance on the Wechsler Adult Intelligence Scale-III (WAIS-III) was compared to performance on the Wechsler Abbreviated Scale of Intelligence (WASI), as well as short form estimations of intellectual functioning derived from WAIS-III performance, in a mixed clinical sample of 72 participants. The WASI verbal IQ (VIQ) score was significantly higher than the WAIS-III VIQ, whereas performance IQ (PIQ) estimates all differed from actual WAIS-III PIQ and full scale IQ (FSIQ). Correlations of WAIS-III scores with WASI scores were consistently lower than were correlations between the WASI-III and all other short forms. Although maintaining administration times of 15 minutesfor a two-subtest FSIQ and 30 minutes for a four-subtest FSIQ, the WASI did not consistently demonstrate desirable accuracy in predicting scores obtained from the WAIS-III. The results suggest that clinicians should use the WASI cautiously if at all, especially when accurate estimates of individuals' WAIS-III results are needed.     

The WISC-III: A reality check

Although the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) is arguably the best instrument currently available for assessing students' intelligence, its use will present practitioners, especially school psychologists, with some unique challenges. Recent research suggests that significant reductions in special education students' WISC-III Verbal, Performance, and Full Scale IQ scores will be found, compared with their previous WISC-R results. This finding will have a profound impact on special education placement decisions. Specifically, students who were previously found eligible for learning disability programs may now no longer evidence the significant discrepancies necessary in order to receive continued services. Conversely, students earlier identified as “slow learners” may now be eligible to receive services for those classified under the category of educably mentally handicapped. In addition, the notion that the WISC-III may underestimate the ability of certain populations of students requires further exploration. This article will address these issues as well as implications for practitioners presently administering the WISC-III.     

Diagnosing written language disabilities using the Woodcock-Johnson Tests of Educational Achievement-Revised and the Wechsler Individual Achievement Test

The writing portions of the Woodcock-Johnson Tests of Educational Achievement-Revised and the Wechsler Individual Achievement Test are often administered when establishing eligibility for special education services due to learning disabilities. The scores on these measures are typically regarded as equivalent although little is known about how scores on the two measures differ for the same students. Differences of only a few points, however, may affect eligibility for special education services. These tests were administered to 25 sixth grade students previously diagnosed with learning disabilities in written expression only. Students' Wechsler scores were consistently higher on the overall writing composite, while there was no difference in the mean scores on the language mechanics subtests. The WIAT Written Expression subtest mean, however, was significantly higher than the Woodcock-Johnson Writing Samples subtest mean. Use of the Wechsler test would be less likely to identify children for special education services in written expression when point discrepancy criteria are utilized for eligibility. Clinicians should be cognizant of the effect of the specific test chosen on eligibility outcome.     

Neuropsychological assessment of learning disabilities: a discriminant analysis

The neuropsychological test scores of 23 learning disabled children were compared with those of a matched population of normal children in the 9-1 to 13-1 age range. All children were administered the Wechsler Intelligence Scale for Children-Revised (WISC-R), a dichotic listening task involving both free and directed recall conditions, a handedness inventory, the Tactile Performance Test and the Category Test from the Halstead-Reitan Neuropsychological Test Battery. A multivariate analysis of variance resulted in a significant separation between groups (p less than .001) using these procedures. A stepwise discriminant function analysis revealed that both of the directed dichotic tasks contributed the most of all 13 measures to the significant group separation. In addition, other cognitive tasks found to discriminate normal from learning disabled children include general verbal processes, concept formation, and tactile memory. These findings suggest that the directed dichotic listening procedure and the WISC-R Verbal IQ measure are reasonably valuable clinical tools in the classification of learning disabilities.     

Effects of familiar proctor on fifth and sixth grade students' test anxiety

The effect of the proctor's familiarity on four groups of students in Grades 5 and 6 was investigated. The 137 children took a reading examination, half of which was administered by a familiar proctor, the other half by an unfamiliar one. Order of conditions was controlled. Analysis showed that students had significantly lower reading scores with the unfamiliar proctor. Students with midrange IQs had significantly lower reading scores than those in the low or high ranges. A significant relationship between test anxiety and effects of the unfamiliar proctor on test performance was shown. Test anxiety contributed significantly to the relationship between self-esteem and performance.

Wire-bending test as a predictor of preclinical performance by dental students

Traditional Dental Aptitude Test and academic grade point average have been shown to be poor predictors of clinical performance by dental students. To refine predictors of psychomotor skills, a wire-bending test was given to 105 freshmen at the beginning of their dental education. Grades from seven restorative preclinical courses in their freshman and sophomore years were compared to scores on wire bending and the three traditional predictors: GPA, academic aptitude, and perceptual aptitude scores. Wire-bending scores correlated significantly with six out of seven preclinical restorative courses. The predictive power for preclinical performance was doubled when wire bending was added to traditional predictors in stepwise multiple regression analysis. Wire-bending scores identified students of low performance. These preliminary results suggest that the wire-bending test shows some potential as a screening test for identifying students who may hae psychomotor difficulties, early in their dental education.     

Attention deficit hyperactivty disorder in Korean juvenile delinquents

This study was conducted to identify attention deficit hyperactivity disorder (ADHD) in Korean juvenile delinquents. Intelligence tests (KEDI-WISC, K-WAIS), the Test of Variables of Attention (TOVA), the Teacher Report Form (TRF), the Youth Self-Report (YSR), and the Rosenberg Self-Esteem Scale were administered to 98 incarcerated Korean adolescents (the delinquent group) and 84 adolescent nondelinquents (the control group). The groups were compared, and significant differences were found for ADHD; 42.4% of the adolescents in the delinquent group were identified as having ADHD, in comparison to 11.9% of the adolescents in the control group. Delinquent adolescents and adolescents with ADHD were found to have lower IQ scores, poorer TOVA performance, more severe problem behaviors, and lower self-esteem than nondelinquent adolescents and adolescents without ADHD. Delinquent adolescents with ADHD consistently fared the worst on assessments of intelligence, TOVA performance, problem behaviors, and self-esteem.     

Prediction of Special Education Need from Preschool Screening Data

Predictive validity of two measures used for early detection of learning problems was investigated using educational group placement as a criterion. Test scores for 240 children were collected prior to kindergarten entrance. Educational placement was examined at the end of grade one based upon assignment to one of four groups (regular education, special education, rescreen-regular education, and retention). Predictive validty was examined using the Discriminant Analysis method. One linear combination of preschool test scores was found which accounted for 95% of the available variance due to group membership. Comparison of group classification using the function and actual group membership indicated that 65% of the children screened were accurately classified on the basis of screening results. The function was successful in the differentiating children in need of some form of special education from those who did not.
