Discussed is the standardization process and presented are the norms for deaf children (6-17 years old) on the performance subtests of the Wechsler Intelligence Scale for Children - Revised (WISC-R). Findings of the standardization study (involving 1,228 deaf Ss) are said to include the greatest deaf-hearing discrepancy on the Coding and Picture…

This review looks at these changes and their impact on the quality of the instrument: alteration of age-range from 5-15 to 6-16; development of new norms; improvement of manual in format and function; and a number of old items deleted and new ones added for the subtests. (RC)

The factor structure in this study was remarkably consistent across the age range, with three factors emerging for each group: Verbal Comprehension, Perceptual Organization, and Freedom from Distractibility. The results of the study are discussed in terms of their clinical applications, particularly interpretation of WISC-R profiles. (Author)

Forty-three junior high learning disabilities programs were surveyed to identify students either specifically disabled in arithmetic (SLDARITH, N=30) or specifically disabled in reading (SLDREAD, N=30). Three types of data were analyzed: size of LD program and school, Wechsler Intelligence Scale for Children (WISC) Verbal and Performance scores,…

The cultural test bias hypothesis represents the contention that all ethnic or racial group differences on mental tests are due to inherent, artifactual biases produced within the tests through flawed psychometric methodology. This address focuses on an empirical evaluation of the cultural test bias hypothesis, especially emphasizing the construct…

THE COMPARATIVE VALIDITY OF THE LEE-CLARK READING READINESS TEST AND THE CALIFORNIA TEST OF MENTAL MATURITY (CTMM) FOR PREDICTING GRADE 1 READING SUCCESS WAS STUDIED. ALL ENTERING FIRST-GRADE PUPILS IN TWO ELEMENTARY SCHOOLS IN A LOW-MIDDLE-CLASS COMMUNITY WERE ADMINISTERED BOTH TESTS DURING THE FIRST 3 WEEKS OF SCHOOL. PERFORMANCES ON THESE TESTS…

Achievement and intelligence tests have been criticized for their adverse effects on the mental health and intellectual development of children. The fault is not with the testing, but with the instructional program. Reforms in testing must be accomplished as part of a revolution in the total instructional program encompassing: (1) a shift from a…

Twenty-six children ranging in age from 6 to 12 years whose tested IQ's were over 160 were tested on three Piagetian tasks of advanced concrete operations and two tests of formal operations. All children passed all concrete operations problems, but only four of the oldest boys passed the formal operations tasks. Findings are discussed in terms of…

Three tests of intellectual performance capacity referring to factors V, S, and R, according to Thurstone's system of primary mental abilities were administered to a total number of 34 subjects. Immediately after finishing an individual item, subjects were asked to estimate the perceived difficulty of that item. The ratings were to be given on a…

The average IQ score of young adult males rose 20 points from World War I to 1960. Among the various causes cited for the rise is the effect of the changing family environment. (JY)

Past validity research involving the Leiter International Performance Scale and the Arthur Adaptation of the Leiter International Performance Scale is reviewed, particularly as it relates to evaluating intelligence of hearing impaired children. (Author)

Compared intrachild variability of five-year-old children on the Primary Mental Abilities Test when subjects reached their fifth birthday after completing at least two years of preschool enrichment. Conclusions, although qualified on the basis of limited sample size, revealed wider intrachild variability with minority children. (Author)
