This study aimed to (a) assess language comprehension in children with autism spectrum disorders (ASD) without intellectual disability, (b) assess differences between ASD diagnostic subgroups, and (c) analyze the relationship between language comprehension and performance and verbal IQ, respectively. The 94 participants (83 boys, 11 girls; 4:0-6:8…

Scores on the Wechsler Adult Intelligence Scale (WAIS) were compared with reevaluation scores obtained four years later on the WAIS-Revised for a group of 108 mildly and moderately retarded adults. The moderately retarded subgroups (N=22) demonstrated significantly higher WAIS-R intelligence quotients. Implications for use of the WAIS-R are…

Investigated the validities of IQs obtained from independent administration Terman-Merrill (T-M) versus the rescoring method (SF) of the short form of the Stanford-Binet Form L-M. Results indicated that the T-M, depending on test sequence, correlated significantly different with the Full Scale Binet IQ than did the SF rescoring method. (Author)

Higher mean IQ scores were obtained on the Wechsler Intelligence Scale for Children (WISC) compared to the revised version (WISC-R). The WISC-R had a facilitative effect on the WISC that did not appear when the WISC was administered first. Differences in instructions may have enhanced the practice effect. (Author/JAC)

Compared the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised in a sample of 88 adults. Indices of obtained correlation coefficients suggested a high degree of similarity between the two scales. Results also showed that WAIS IQs were significantly higher than corresponding IQs on the WAIS-R. (WAS)

Scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and Wechsler Adult Intelligence Scale-Revised (WAIS-R) Verbal, Performance, and Full Scales were compared for 26 adolescents with educable mental handicaps. The WAIS-R, while strongly correlated with the WISC-R, provided higher scores on all three scales. Several WISC-R…

Data from the Colorado Adoption Project for 493 first-grade adopted and nonadopted children are used to separate parental intelligence quotient (IQ) from the effects of school environment. Several of the variables show direct environmental associations with reading and mathematics achievement independent of effects of parental IQ. (SLD)

Administered the Slosson Intelligence Test (SIT) to 92 preschool children. Administered the Stanford-Binet Intelligence Scale to a sample of the group, and the results were compared to the results from the SIT. Results indicated the SIT overestimated the performance of average preschool children. (Author)

Reviewed records of 94 mentally retarded adolescents who had been given the Wechsler Intelligence Scale for Children or the Wechsler Intelligence Scale for Children (Revised). Although there were no significant differences between the groups, the WISC tested lower than the WISC-R by an average of about two points. (Author/JAC)

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…

Inmates score significantly lower on the second edition (BETA II) than on the first edition (BETA I), regardless of the order of administration. BETA I score distributions were unaffected by the order of administration. BETA II score distributions depended on whether BETA II was administered first or second. (Author)

A written intelligence test with verbal, reasoning, and spatial subscales was administered to two comparable national samples of 1,000 thirteen-year olds in Sweden, tested in 1961 and in 1966. The increases were greater for girls than for boys, and the changes occurred simultaneously with several changes in social and educational conditions. To…

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…

Sex differences in variability in the national norms of the Differential Aptitude Tests, Preliminary Scholastic Aptitude Test/Scholastic Aptitude Test, Wechsler Adult Intelligence Scales, and California Achievement Tests were examined. Compared to females, males were consistently more variable in quantitative reasoning, spatial visualization,…

Compared the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised (WAIS-R) in a sample of college students (N=70). A highly significant test order interaction was found. The WAIS-R will result in significantly higher ability estimates when administered following the WAIS than the WAIS will when following the WAIS-R. (JAC)
