The positive emotions have proved to be a source of embarrassment to psychologists. Discussions of fear, anxiety, depression, anger, grief, etc., are plentiful in the psychological literature.

Although Carlson’s analysis is now somewhat out of date, I doubt that a survey of current textbooks would reveal a major change in emphasis (except perhaps for a recent upsurge of interest in issues related to sexual behavior, including romantic love).
