Examined concurrent validity of Nonvocal Cognitive Quotient (NVCQ) of Cognitive Abilities Scale (CAS) and Stanford-Binet Intelligence Scale: Fourth Edition (Binet IV) for two and three year olds. Found adequate concurrent validity for CAS NVCQ and Binet IV Verbal Comprehension at both age levels as well as for Nonverbal Reasoning/Visualization…

Evaluated the extent to which the Graduate Record Examinations General Test measures the same constructs for older test takers that it does for younger examinees. Results suggest that the convergent validity of the test is similar across the age groups, but discriminant validity is somewhat different for older examinees. (Author/RWB)

The Token Test and the Wechsler Intelligence Scale for Children were administered to 46 nonretarded children (6-17 years old) with learning problems. (Author)

Compared performance of high- and low-education adults on traditional and meaningful space and reasoning measures. Separate analyses of variance for reasoning and space revealed main effects for education and age on both abilities. Results indicated highly educated older people performed more like their younger peers. (Author/JAC)

Reviews developmental literature on cognitive gender differences; and compares past and present trends in gender differences, by age, from standardizations of the Wechsler Intelligence Scales and the California Achievement Tests. Decreases are found in gender differences for adolescents but not for adults. Implications are discussed. (SLD)

This paper presents results of a LISREL factor analysis on data from the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Wechsler Intelligence Scale for Children-Chinese Revised (WISC-CR) (published in 1986) for children ages 6.5 to 16.5 years, using a standardization sample of 200 children (100 males and 100 females) at each of…

The stability of some dimensions of ability between the ages of 12 and 15 years was investigated for 225 boys and 242 girls in Sweden. Testing in grades 6, 8, and 9 indicated high stability for the general intelligence factor and for the residual of the General Visual factor. (SLD)

The stability of the Kaufman Assessment Battery for Children (K-ABC) was studied by examining its performance over a 5-year interval with 16 non-handicapped children aged 45 to 61 months at the beginning of the study. Global scale stability coefficients (corrected for restriction in range) for Time 1 testing (age 4 years) and Time 4 testing (age 9…
