Psychologists and educators offer their views on the three fundamental questions of what they refer to when they talk about emotion, what it is that changes during emotional development, and what roles developing emotions play in the lives of individuals. The perspectives they use are biological and differential emotions, functionalist, systems, and social and cultural. The goal of the collection is to clarify points of agreement and disagreement among theorists and researchers. Annotation c. by Book News, Inc., Portland, Or.
