Abstract
Over the past twenty years there have been so many newly revealed facts and theoretical developments in the field of the psychology of emotions that, as C. Izard [14] remarked, one would be fully justified in speaking about a revolution in this area. While the motivating role of emotion remains unquestioned (and, furthermore, confirmed by the new data), the earlier idea that emotions have disorganizing and disadaptive effects has been replaced with the notion that emotions are a major adaptive mechanism. Thus, C. Izard asserts, "A fundamental principle of human behavior is that emotions energize and organize perception, thinking, and action" [14, p. 25]. All emotions, he says, have adaptive functions that developed over the course of evolution.
