Early Cognitive Functioning: Sex and Race Differences.
Denno, Deborah; And Others
This longitudinal study was designed to investigate the nature and extent of sex differences in both verbal and spatial abilities among black and white children. Six scales of early cognitive functioning were administered at three times (at 8 months, 4 years and 7 years) to 3,013 children. Two major hypotheses were examined: (1) if cognitive development is related to maturational rate, which differs in terms of sex and race, early intelligence scores will show a sex by race interaction; and (2) if spatial abilities are the most influenced by maturational rate, this interaction will occur more strongly for spatial than for verbal abilities. Results provided only partial support for these hypotheses; a slight sex by race interaction was found at 4 and 7 years for both verbal and spatial abilities and sex by race differences were more apparent in 7-year-olds' spatial abilities relative to verbal abilities. Specifically, white males showed the highest level of intellectual performance, followed by white females, black females, and black males. However, sex differences were greater for whites than for blacks, and race differences were greater for males than for females. Findings are discussed in terms of possible maturational and environmental influences on cognitive abilities among different sex and racial groups. (Author/MP)
