The classification of intelligence has been a prime interest to many for over three-quarters of a century. The Wechsler scales of intelligence and the development of factor analysis have both played major roles in the shaping of psychometric thought. An examination of this joint history by means of a review of the factor analytic studies of the…

Wechsler Intelligence Scale for Children-Revised Verbal, Performance, and Full Scale IQs for matched-pair subjects were compared, evaluating performance in morning and afternoon testing. No significant differences in mean IQ as a function of time of testing were shown. Greater variability occurred for morning performance on the Verbal and Full…

Two nested structural models are developed to determine whether test-session behaviors affect the manner in which intelligence is measured or influence the constructs being measured. Results indicate that test-session behaviors play a larger role influencing the mechanisms of measurement than on the constructs of intelligence. (Author/EMK)

Investigated correlations between two intelligence measures for exceptional children. Corrected correlations between the tests indicated differences with correlations reported in one manual. Relationships were generally higher than those reported elsewhere. Implications are discussed, especially those involving the use of correlations between…

So as to compare predicted achievement based upon WISC-R IQs and observed achievement by the WRAT standard scores, both instruments were administered by the same school psychologist to 282 urban students referred for psychological evaluation. The correlations obtained were substantial. (Author)

One hundred students (ages 6 to 17) identified as experiencing academic difficulties were administered both the Draw-A-Person and the Wechsler Intelligence Scale for Children-Revised (WISC-R) to assess the relationship between the two instruments with this population. Analyses indicated significant correlations between the various scores obtained…

Investigated stability of the Wechsler Intelligence Scale for Children-Revised (WISC-R) intelligence quotient scores of 32 exceptional students over six-year interval. Used 20 learning disabled and 12 mentally disabled students aged 6 to 16. Test-retest findings indicated median reliability value of .74. Discusses implications for clinicians and…

Using the Guide to the Assessment of Test-Session Behavior for the WISC-III and WIAT (GATSB), observations were recorded for 969 children between the ages of 6 and 16 years. Children who exhibited higher levels of avoidance, inattentiveness and uncooperative behaviors while being tested tended to exhibit lower WISC-III scores. (RJM)

Examined the concurrent validity of the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) in a sample of 101 students aged 6 to 16, referred for learning, mental or emotional disabilities. Results showed significant correlations between the PPVT-R and the WISC-R overall sample. (JAC)

The development and standardization of the third edition of the Wechsler Intelligence Scale for Children-Revised (WISC-R) are described. The existence of documented historical trends was a significant factor in the project to revise the WISC-R, which is the most widely used intelligence battery in North America. Development of the third edition…

The tetrad of subtests of the Wechsler Intelligence Scale for Children-Revised (WISC-R) that best predicts the WISC-R Full-Scale intelligence quotient (IQ) was determined for 1,589 Appalachian students referred for evaluation in grades 1-4, 5-8, and 9-10. The sample was divided into three groups. Students in grades 1 through 4 (n=655) were those…

This book is designed to provide insight into the ways in which psychologists conduct psychoeducational assessments in a variety of settings. Each contributed chapter gives a detailed and practical discussion of a particular assessment instrument or strategy along with a detailed case study. Chapters have the following titles and authors:…
