Intellectual engagement (IE) refers to enjoyment of intellectual activities and is proposed as causal for knowledge acquisition. The role of IE for cognitive development was examined utilizing 2-year longitudinal data from 112 ninth graders (average baseline age: 14.7 years). Higher baseline IE predicted higher baseline crystallized ability but…

Analysis of correlations between Verbal and Full Scale IQ scores for 231 high-IQ psychiatric outpatients indicated that Verbal IQ appears partially valid as a WAIS short form for this higher IQ group. Results are interpreted in terms of Resnick and Entin's short form validity criteria. (Editor/SJL)

Examined 128 children for contributions of biomedical risk conditions, SES, and HOME scores to prediction of intelligence, and association of extreme scores on HOME and SES to intelligence-test performance. Found home environment was the most important predictor of intelligence at all ages, with SES showing a smaller effect beginning at age 5.…

Zajonc and Bargh's (EJ 241 537) application of the confluence model to six national data sets is critiqued. Extreme differences in intelligence levels are predicted between nations, including substantial retardation for some populations. Moreover, the parameter values used do not allow mental growth functions which are consistent with previous…

Regression lines for the prediction of Wide Range Achievement Test (WRAT) scores by Wechsler Intelligence Scale for Children (WISC) and WISC Revised (WISC-R) intelligence quotients were compared across race, by the Potoff technique. Subjects were 36 black and 30 white children who were referred for psychological evaluation because of learning or…

This study examines cultural bias in the Wechsler Intelligence Scale for Children. Results indicated no evidence of specific factors peculiar to Blacks v Whites, and rank order of item difficulties was similar in both groups. Race differences were due to differences in mental maturity rather than to test bias. (Author/RD)

A study of the intellectual talents involved in learning a foreign language compared the composite predicted score of high school students on the Pimsleur Language Aptitude Battery with selected factor scores on the Structure of Intellect-Learning Abilities Test to determine whether any of the factors correlate highly with foreign language…
