ABSTRACT
Psychologists identify emotions as the essential “building blocks” of well-being (Kahneman, Diener, & Schwarz, 1999). This chapter examines the theoretical and empirical basis for this claim. First, it discusses the operational definitions of emotions and the theoretical perspectives that underlie these definitions, along with the measurement techniques that are associated with these perspectives. Second, it traces the processes associated with emotional development from infancy through adolescence. Next, it reviews the evidence for emotions being essential elements of positive development, both as contributors to and measures of well-being. The chapter also addresses the factors that may affect the promotion of positive emotions, emotion understanding, and emotion regulation during childhood and adolescence. Finally, it suggests directions for future research.
