Fogelson gives his evaluation of Hallowell's role as progenitor of psychological anthropology. He cites his innovative use of the Rorschach in cross-cultural research, his distinction between cultural and psychological levels of explanation, and his criticism of ethnocentric bias in studies of acculturation. His conception of cultural dynamics included different forms of cultural change, as well as mediating

mental processes and behavior. A capacity for self-objectification represents a critical stage in the development of culture. The concept of the self brings together collective and individual consciousness.
