This article presents evidence suggesting that sex differences in aggression are universal, but that the differences are also highly susceptible to experiential modification. Following a “phylogenetic perspective” that emphasizes the interaction of genotype and experience, the author finds that boys are on average more aggressive than girls but adult males as a group are not significantly more aggressive than women.

This article investigates potential relationships between food deprivation, parental rejection, and personality development. Findings indicate that a series of adult personality characteristics (e.g. self evaluation and emotional responsiveness) are better predicted by parental rejection than by nutritional variables.

The purpose of this book is to introduce a conceptual and methodological perspective called the "universalist approach," and to use this approach in exploring the pancultural antecedents and affects of parental acceptance-rejection of children,

This chapter investigates the relationship between parental acceptance/rejection and personality characteristics of children and adults. The author analyzes evidence from two cross-cultural samples, one cross-national psychological sample, and one all-American sample. Only the tests using cross-cultural samples are reported here. Results suggest that parental rejection is related to certain personality characteristics of adults and children.

This study investigates cross-cultural determinants and consequences of parental affection and rejection. Findings indicate that accepted children are less hostile and dependent and have higher self-esteem in both childhood and adulthood. Additional findings suggest that children who experienced parental acceptance had higher emotional responsiveness, better world view, more emotional stability, generosity, and nurturance as adults.
