This research is based on extensive findings regarding the impact of separation between mothers and infants and its lasting implications. It incorporates a wide array of animal and human studies, pinpointing the link between early bonding and the values associated with social orientation. This pioneering research on attachment of non-White, Educated, Industrialized, Rich, Democratic (WEIRD) Society involved 91 participants from eastern Mexico, amidst rapid sociocultural and economic shifts. Four primary hypotheses were examined, centering on prosocial behavior, levels of attachment, and the interplay between attachment and gender in response to evolving societal roles. The findings upheld the hypotheses and were analyzed in the context of Greenfield's theory of sociocultural change and human development.
