"This is an accessible new book that reviews much of the insightful new research on emotions conducted over the last ten years. It expands on the theory of emotions introduced in Nico Frijda's earlier work, and addresses a number of unanswered, basic problems on emotion theory. The author's goal is to better understand the underlying psychological mechanisms of emotion. Professor Frijda also examines previously neglected topics of emotion such as determinants of emotional intensity, the duration of emotions, and sexual emotions. It touches on both evolutionary and neuroscientific explanations."--BOOK JACKET.
