http://en.wikipedia.org/wiki/Psychological_anthropologyPsychological anthropology is a highly interdiscplinary subfield of anthropology that studies the interaction of cultural and mental processes. In particular, psychological anthropologists tend to focus on ways in which humans' development and enculturation within a particular cultural group, with its own history, language, practices, and conceptual categories, shape processes of human cognition, emotion, perception, motivation, and mental health. It also examines how the understanding of cognition, emotion, motivation, and similar psychological processes inform or constrain our models of how cultural and social processes work. It is comprised of several schools or subfields, each of which has varying approaches within.
