Abstract Genetic and environmental influences on IQ were examined in various subgroups of the Texas Adoption Project sample, including subdivisions by age, sex, and socioeconomic status. Also investigated were the effects of sampling error, restriction of range, ureliability of measures,whether or not the adoptive parents had information about the biological mother, whether or not the biological mother had elevated MMPI scores, and differences between verbal and performance abilities. The principal method used was path analysis, and the heritabilities obtained fell mostly in the range of 0.30 to 0.65.
