Both psychoanalytic views of attachment and evolutionary theories of imprinting suggest that mates may be preferentially chosen to resemble one's parents. Using data from a large Dutch study of twins and their families, we tested these hypotheses with regard to personality traits from the Five-Factor Model. Little evidence of parent/spouse similarity was found, although women did tend to select a husband who resembled their parents with regard to Openness to Experience. This effect may be due to the influence of Openness on their social worlds, rather than to their experiences in early childhood. © 2012 Elsevier Inc.
