This high level introductory psychology text covers both the biological basis of psychology and the role of culture in shaping basic biological processes. Theories are provided in a conceptual framework that captures the excitement and tensions of the field. The book takes a micro to macro focus, from biology and neuroscience to culture. It demonstrates the integration between thoughts, feelings, motivations, social behavior, etc. Revised to include research and a more balanced coverage with four new perspectives - psychodynamics, behavioral, cognitive, and evolutionary - each introduced in depth to allow readers to begin conceptualising psychological data.
