This study compared global scores of 26 Australian students (ages 4 to 16) with mental retardation on the third and fourth editions of the Stanford Binet Intelligence Scale. Analysis indicated a fairly strong positive relation between the two tests, suggesting that the fourth edition may be substituted for the older instrument in longitudinal…

Thirty-five gifted elementary children were tested with the Wechsler Intelligence Scale for Children III (WISC-III) and results were compared to a previous administration of the WISC (Revised). Scores were significantly higher on all three WISC-R global scales and most subtest scaled scores. Correlation coefficients between the tests were…

The relationship between speed of information processing (SIP) and psychometric intelligence was investigated by giving 60 college students (22 males and 38 females) 2 choice reaction time (RT) tests (modified Hick paradigm) and Raven's Advanced Progressive Matrices. Results support an association between intelligence and SIP. (SLD)

Comparison of Wechsler Intelligence Scale for Children (WISC)-Revised and WISC III IQs for 64 students with specific learning disabilities and 55 students with mental retardation (MR) found that correlations were lower than those reported in the WISC-III manual. Only Performance IQs for students with MR matched the correlations reported in the…

Compared the test scores of high and low anxious subjects when the Wechsler Adult Intelligence scale was administered by a trained examiner or mechanically. Findings indicated that performance was influenced by test administration procedures. There was a trend to score higher on the test given by an examiner. (Author/JAC)

Compared the derived mental age (MA) of the Stanford-Binet to the test age (TA) of the Wechsler Intelligence Scale for Children (Revised) in 100 children. For subjects whose WISC-R scores fell within the TA table, the two were comparable. When extrapolated TAs were required, the scores were not comparable. (Author/JAC)

This research studied the interchangeability of individually administered and group administered cognitive tests. Seventy undergraduate students took the Hebrew version of the WAIS-R (Wechsler Adult Intelligence Scale-Revised), and their IQs were measured. They also took the IPET (Israeli Psychometric Entrance Test) and their IPET scores were…

Field dependence and spatial ability are examined as different labels for a common underlying dimension. Sixty college students completed two tests of field dependence and two tests of spatial ability. Results of an analysis of covariance found no evidence to view the two traits as distinct from each other. (Author/LMO)

Analyzed published data on the Wechsler Adult Intelligence Scale (WAIS) to ascertain whether the Information and Vocabulary subtests can function as measures of intelligence. Concluded that the addition of more WAIS subtests will not result in any increase in predictive validity and these additional tests, therefore, lack incremental validity.…

Cognitive differences between 987 LD children and 178 EH children in public schools on a psychoeducational assessment battery were studied, and differences in factor structure were investigated. Caution is suggested in interpreting the results of multivariate statistical analyses, which indicated heterogeneity in the matrices of LD and EH…
