Psychodynamic Perspective Neoanalysts focus more on conscious choice and self-direction then unconscious processes – Karen Horney – Erik Erikson

Perspective on Learning Social Cognitive – People modify and create their environment – Cognition plays a key role – Observation

Sociocultural Perspective Focuses on the influence of differences among people on behavior and mental processes – Ethnicity, gender, culture, socioeconomic status
