A new perspective on emotions.

This paper reviews the recent history of the study of human emotions in psychology and traces the factors that have been responsible for a remarkable increase of interest in emotions, especially in human development. In particular, it traces the rise of the study of emotions as regulators of human behavior. A particularly clear and powerful illustration of the regulatory role of emotional expressions on behavior is the phenomenon of social referencing. This concept deals with the use of emotional information in another's facial, vocal or gestural expression to clarify uncertain situations. Research on social referencing is reviewed, showing the importance of social referencing with infants as young as 8.5 months. The clinical implications of the concept are briefly explored.
