Book excerpt: This textbook is designed for upper-level courses on affective science. The lively, integrative chapters review empirical research on emotion at every level of analysis, including the neural bases of emotions, complex emotions, emotion and cognitive processes, emotion regulation, and an examination of social levels of analysis including emotions in groups, gender, and cultural differences. This 2nd edition has greater inclusion of research findings from neuroscience and includes highly effective learning devices, such as ‘Development Detail’ boxes; bolded key terms; ‘Learning Links’ to online supplemental materials; and many tables, figures and illustrations that make topics come alive.
