Performed orthogonal and oblique factor analysis using the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization sample (N=1,880). Analysis of the variance components for each subtest at every age level revealed a substantial proportion of subtests at a wide range of age levels evidenced high or intermediate levels of specific…

An investigation of the relationship between effective intelligence, as conceptualized in the Adaptive Behavior Scale and Wechsler Adult Intelligence Scale subtest scatter for 102 mentally retarded subjects, revealed that increased scatter was inversely related to some adaptive behavior domains and directly related to certain maladaptive behavior…

Discusses the significance of confidence intervals around IQ scores based on a misleading interpretation of the standard error of measurement terms provided in the Wechsler Adult Intelligence Scale-Revised (WAIS-R) manual. Presents standard error values and a table for determining the abnormality of verbal and performance IQ discrepancies.…

The McCarthy Scales of Children's Abilities and the Stanford-Binet were compared as instruments for identifying and assessing intellectually gifted preschool and primary aged children. The McCarthy Scales consistently produced lower scores than the Binet. Low to moderate correlations existed between the two scales. (Author/CL)

Changes in the full scale reliability of the WISC-R were computed at three age levels when each subtest was omitted by itself. The same procedure was followed with those subtests which independently had the smallest effect in lowering full scale reliability. Cautions were noted concerning the exclusion of subtests. (Author)

Reanalysis of Wakefield and Carlson's data confirmed canonical correlations of .84 and .69, but analysis of redundancies revealed that only 34 percent of the total WISC subtest variance is redundant with the ITPA and 39 percent of the ITPA subtest variance is redundant with the WISC. (Author)

This study investigated the effect of verbal reinforcement (verbal approval contingent upon correct responses) upon the intelligence test performance of normal college students. (Author)

This study was designed to compare the performance on selected intelligence tests of a group of Canadian Indian children who had never been to school with the performance of a similar group of children who were attending school regularly. (Author/RK)

Two conventional scores and a weighted score on a group test of general intelligence were compared for reliability and predictive validity. (Editor)

This article examined what Scrutiny had to say about education up to the early war years of the 1940s and how Scrutiny reacted to the early post-war years during which the Labour Party was in power and were taking the first steps to implement the Education Act of 1944. (Author/RK)

Deaf elementary school children were administered the Leiter International Performance Scale and the five nonauditory, nonverbal subtests of the Illinois Test of Psycholinguistic Abilities. The intellectual quotient derived from the Leiter and the psycholinguistic quotient derived from the five visually oriented subtests were then correlated. The…

This article reviews and critiques studies involving the WISC with samples of blind subjects. Discussion focuses on reliability, validity, and research strategy. Recommendations and suggestions for further research place emphasis upon experimental analysis of behavior. (Author)

Purpose of the present investigation was to provide further normative data on the D 48 using American college students and to determine the relationship of scores on the D 48 to those on (a) the Otis Mental Ability Test, Gamma Form, AM, and (b) a nonverbal test, Revised Minnesota Paper Form Board. (Authors/CB)

The present study investigated: (a) the relationship between IQ test scores and ability to follow specific instructions for solving matrices; and (b) the relationship between IQ test scores and the ability to follow strategy instructions for solving matrices. Findings from this investigation may clarify the relationship between intelligence and…
