The major finding of this study is that there is a larger socioeconomic status or Negro-White difference on intelligence measures than on measures of rote learning and memory. The difference in the performance of Negro and White children increases with age. (EH)

Trotman responds to two criticisms of her previous research (EJ 168 902) on racial differences in intelligence and achievement. She clarifies the conclusions criticized by Longstreth (TM 503 913) and criticizes the conclusions reached by Wolff (TM 503 914). (BH)

Trotman (EJ 168 902) indicated that Black and White families of similar socioeconomic status differ widely in intellectual home environment, and suggested the nonutility of socioeconomic status as a control in racial comparisons of IQ. The validity of Trotman's conclusions is questioned, both for methodology and results. (Author/BH)
