We compared the extent to which the long-term influence of family socioeconomic status (SES) on children's school performance from age 7 through 16 years was mediated by their preschool verbal and nonverbal ability. In 661 British children, who completed 17 researcher-administered ability tests at age 4.5 years, SES correlated more strongly with…

Cognitive impairment is common among children born very preterm (VPT), yet little is known about how this risk changes over time. To examine this issue, a regional cohort of 110 VPT (= 32 weeks gestation) and 113 full-term (FT) born children was prospectively assessed at ages 4, 6, 9, and 12 years using the Wechsler Preschool and Primary Scale of…

This study was conducted to determine how items of the Stanford-Binet Intelligence Scale, Form L-M, had performed in the 1930's standardization sample in comparison with the 1972 standardization sample. (SB)

Found that black children's IQ scores were 1 SD lower than those of white children. Adjustments for ethnic differences in poverty reduced the differential by half; adjustments for differences in home environment reduced it by…
