Although intelligence tests are among the most widely used psychological instruments in school psychology, at the current time, little is known about how practitioners interpret them. The primary purpose of this study, therefore, was to determine how intelligence tests are interpreted by school psychologists, particularly for the identification of…

Charles Spearman and L. L. Thurstone were pioneers in the field of intelligence. They not only developed methods to assess and understand intelligence, but also developed theories about its structure and function. Methodologically, their approaches were not that distinct, but their theories of intelligence were philosophically very different --…

This article briefly reviews the history of intellectual assessment of children and youth in the United States of America, as well as current practices and future directions. Although administration of intelligence tests in the schools has been a longstanding practice in the United States, their use has also elicited sharp controversy over time.…

Learning Disabilities (LDs) affect a significant number of students in elementary and secondary school. In order for these students, along with parents and teachers, to understand the nature of their specific difficulties, and have equal opportunity in academic settings, a comprehensive psychological report containing properly informed…

Profile analysis was performed on Wechsler Intelligence Scale for Children-Revised (WISC-R) scores of 29 learning disabled students (6-10 years old) in a Specific Learning Disabilities (SLD) program, to determine whether subtest patterns for initial and re-evaluation WISC-R administrations would differ significantly. Profile analysis was applied…

The paper reviews factor analytic studies concerning the Wechsler Intelligence Scale for Children-Revised (WISC-R) profiles of children with learning disabilities (LD). Considered are the following topics: subtest profiles of backward readers, a sex difference in coding, and derivation and use of grouped subtest scores in profile analysis. The…

This study suggests that the Peabody Picture Vocabulary Test and the Slosson Intelligence Test measure different and limited aspects of a child's ability and are only rough estimates of his/her capability of what is generally termed intelligence. Scores from either should be interpreted with care and in light of other information about a child.…

Examined scatter analysis and Kaufman regroupings of Wechsler Intelligence Scale for Children-Revised scores. Findings from 31 non-learning-disabled children and 29 learning-disabled children revealed significant difference in Verbal and Performance intelligence quotients between learning-disabled and nondisabled children, with significantly more…

Investigation of the stability of Wechsler Adult Intelligence Scale Revised scores of 25 college students over a 4-year period found that global and subtest scores were highly stable. Subtest scores tended to be higher on the retest, but global scores were not despite four years of educational experiences between test administrations. (Author/DB)

The evidence suggested that LD children, as a group, exhibit a characteristic WISC(-R) profile whereas few individual LD children actually conform to this pattern. It was concluded that WISC(-R) profiles may not be useful for differential diagnosis of LD students. (Author)

Investigates the prevalence and utility of the ACID, ACIDS, and SCAD profiles of the WISC-III. Findings support the use of conditional probabilities and incremental gains based on the actual incidence from a referred population to assist in differential diagnosis; however, none of the profiles is recommended as a criterion for determining…

The relation between average deviation, as determined using the Illinois Test of Psycholinguistic Abilities, and Stanford-Binet intelligence scores was examined using a preschool sample. Results revealed a curvilinear relation between total average deviation and Stanford-Binet intelligence scores. Use of average deviation as an index of…

This study evaluated the external validity of a measure of IQ subtest variability, the profile variability index (PVI), with a sample of 146 children referred for psychological testing. Correlation of PVIs on each intelligence test with achievement scores and indexes of discrepancy between actual and predicted scholastic achievement found…
