PHENOTYPIC ASSORTMENT VERSUS SOCIAL HOMOGAMY FOR PERSONALITY, EDUCATION, ATTITUDES, AND LANGUAGE USE

As part of a follow-up study of offspring who participated in the Hawa ii Family Study of Cognition (HFSC) from 1972 to 1976, 40 pairs of now -adult siblings of Caucasian ancestry, including 23 pairs where one si bling spouse was also tested and 17 pairs where both sibling spouses w ere tested, and 36 pairs of siblings of Japanese ancestry, including 2 6 pairs where one sibling spouse was also tested and 10 pairs where bo th sibling spouses were tested, were administered the Eysenck Personal ity Questionnaire (EPQ) and the Comrey-Newmeyer Radicalness-Conservati sm Scale and reported on their years of education and pidgin and stand ard English use. Model-fitting analyses using delta paths suggested no significant degree of assortative mating for EPQ Extraversion, Neurot icism, and Psychoticism. Assortment for the EPQ Lie Scale, Radicalness -Conservatism, education, and language use was found to be mostly due to active phenotypic assortment, with significant effects of social ho mogamy found for Radicalness-Conservatism and pidgin use. These latter findings contrast with the stronger effects of social homogamy on ass ortative mating found for Japanese and Chinese ancestry sibling-spouse pairs in the HFSC parent generation.
