Psychometric tests related to vocabulary assessments are, for the most part, restricted in their use by trained professionals and/or are costly. These restrictions limit their use, especially for research purposes. To circumvent these limitations, the Raney Vocabulary Measure was created for assessing vocabulary proficiency, specifically for…

The Peabody Picture Vocabulary Test (PPVT) is a widely used test of receptive vocabulary, but no researchers to date have examined the performance of low-educated, low-literate L2 adults, or compared these individuals' performances to their more highly educated peers. In this study, we used many-facet Rasch analysis and mixed-effects linear…

Current taxonomies of intelligence comprise two factors of mental speed, clerical speed (Gs), and elementary cognitive speed (Gt). Both originated from different research traditions and are conceptualized as dissociable constructs in current taxonomies. However, previous research suggests that tasks of one category can be transferred into the…

The purpose of this article is to understand the decision-making processes by assessment personnel when choosing instruments to evaluate students with learning disabilities. Eight school personnel responsible for the evaluation of students in Texas participated in face-to-face, semistructured interviews. The instruments chosen were based on a…

Strong correlations exist between signed and/or spoken English and the literacy skills of deaf and hard of hearing students. Assessments that are both valid and reliable are key for researchers and practitioners investigating the signed and/or spoken English skills of signing populations. The authors conducted a literature review to explore which…

Previously, fine motor skills have been of little or no interest to giftedness research. New lines of thought have been advanced that imply that fine motor skills can be of significance in the identification of gifted persons as well as gifted underachievers. This would also have consequences for the diagnostic process underlying identification.…

Background: Evidence suggests that, as a group, patients with schizophrenia have intellectual deficits that may precede the manifestation of psychotic symptoms; however, how successfully intelligence tests are able to discriminate schizophrenia from other psychotic disorders has yet to be investigated in detail. Methods: Using Wechsler Adult…

Older adults (n=224) completed Wechsler Adult Intelligence Scale-Revised (WAIS-R) and questionnaire eliciting information about subjects' perceptions of WAIS-R across five categories. Most subjects experienced WAIS-R as interesting, challenging, motivating, and within their endurance. Picture Arrangement and Block Design were only two subtests…

Subtest specificities were determined for each of the 11 subtests of the Wechsler Adult Intelligence Scale--Revised (D. Wechlser, 1981) for a sample of 200 psychiatric inpatients. Seven subtests were judged to have adequate to ample specificity; four subtests were found to have inadequate specificity for ipsative interpretation. (SLD)

The study examined the stability of WISC-R (Wechsler Intelligence Scale for Children-Revised) Verbal-Performance (V-P) differences at the triannual reevaluation of 71 learning disabled students from Hawaii. Results revealed a slight increase of three points in the V-P differences, with a correlation of .55 between the Time 1 and Time 2 V-P…

Paper discusses advantages and disadvantages of using the Leiter International Performance Scale with autistic children and presents the results of a study comparing the performance of 18 autistic children on the Wechsler Intelligence Scale for Children-Revised and the Leiter. Results showed a high positive correlation between the WISC-R…

Studied the complementary nature of Illinois Test of Psycholingusitic Abilities (ITPA) and Wechsler Intelligence Scale for Children Revised (WISC-R) in a sample of 60 language-impaired children. Results suggest that the ITPA is more sensitive to differences in children's verbal and performance abilities than the WISC-R. (SLD)

Used the national standardization sample (n=2,200) of the Wechsler Intelligence Scale for Children Third Edition (WISC-III) to investigate differential item functioning (DIF) in 6 WISC-III subtests. Detected both uniform DIF and nonuniform DIF, finding DIF for about one third of the items studied. Discusses implications for use of the WISC-III.…

The Wechsler Intelligence Scale for Children--Revised and the Wechsler Adult Intelligence Scale--Revised were administered in a conterbalanced design to 14 educable mentally handicapped 16-year-olds. Verbal, Performance, and Full Scale IQ scores were compared. Correlations and matched t-tests were computed and the results indicated that Verbal and…

The study examined the WISC-R (Wechsler Intelligence Scale for Children-Revised) profiles of 26 intellectually gifted students with respect to idiographic and normative variability in performance between scales and among subtests. Results indicated (even among highly homogeneous ability groups) significant variability in performance, reflecting…
