Cognition often involves goals and representations that carry an affective quality or tone, whereas emotions often involve cognitive processesperception, representations, and interpretations of events. Emotion, cognition, and social interaction are not readily dissociated from one another in daily experience; the relationship between cognition and emotion has been the focus of extensive research in the last decades (e.g., Frijda, 1986; Lazarus, 1991) as well as the links between cognitive and emotional development (e.g., Harris, 1989; Izard, 1991; Sroufe, 1995). Neo-Piagetian theorists are no exception in this regard, and offer several contributions to the debate in this field.
