This is an upper-level introductory psychology text that presents the core aspects of the subject. The authors use a set of five themes that are woven throughout the text to unite all of the material. These primary themes include: biological, learning, cognitive, developmental, and sociocultural factors. In each succeeding chapter the themes are introduced at the beginning of the chapter in a set of thematic questions, woven into the chapter material, and then summarized at the end.
