Human development doesn't occur in a vacuum. Rather, it is deeply rooted in, and affected by, culture. This textbook examines how culture affects several domains of development, including cognition, emotion, sociolinguistics, peer relationships, family relationships, and more. The chapters highlight differences between "WEIRD" cultures (Western, educated, and from industrialized, rich, and democratic countries) and non-WEIRD cultures, as well as differences with respect to gender, race/ethnicity, socioeconomic status, and other identity markers.
