Further investigations of educational and occupational attainment in the Hawaii family study of cognition

Abstract

Associations of measures of grandparental status, parental status, cognitive abilities, and personality, and own cognitive abilities and personality with educational and occupational attainment are reported for 249 offspring, now 25 years or older, from the Hawaii Family Study of Cognition (HFSC). In general, across two ethnic groups (Americans of European ancestry (AEA) and Americans of Japanese ancestry (AJA)), the data suggest that family background had a relatively trivial influence, own cognitive abilities (particularly verbal ability and general intelligence) substantial influence, and own personality some influence on the educational and occupational attainment of males, while family background had a far more substantial influence than own ability on the attainment of females. Educational attainment was generally found to be substantially predictive of occupational attainment. Hierarchal multiple regression analyses were conducted to assess the influence of parents’ abilities over and above grandparental status and the influence of offsprings’ abilities over and above parental status and abilities on their respective educational and occupational attainments. These analyses also indicated that family background was a much greater influence than own ability on the attainment of AEA female parents and both AEA and AJA female offspring. These findings for female offspring were further confirmed by analyses of parent‐offspring and within‐sibship differences in attainment.
