VAN DEN OORD, EDWIN J. C. G. ROWE, DAVID C. A Cousin Study of Associations between Family Demographic Characteristics and Children's Intellectual Ability Intelligence 27 (1999): 251-266 Cohort(s): Children of the NLSY79 ID Number: 3880 Publisher: Elsevier Cousins and siblings from the National Longitudinal Survey of Youth (NLSY) were used to evaluate for several frequently studied environmental variables, the null-hypothesis that correlations with children's IQs represented causal effects. For the majority of the tests the null-hypothesis had to be rejected. Cousin correlations for age [of] mother at the birth of her first child, maternal self-esteem, highest grade completed by the mother, highest grade completed by the father, family poverty status, marital status of the mother, and number of children, suggested that these associations may for an important part be spurious and confounded by third variables that are shared by cousins and affect both the children's home environment as well as their intellectual abilities. Results for quality of the home environment were more equivocal and suggested at least smaller effects of third variables. Search returned 1 items. Search Start: 20:42:10 Search Finish: 20:42:10
