Many emotion researchers would probably agree that at least some aspects of discrete emotions are evolutionarily conserved (e.g., the sensation/feeling component cannot be learned). Such agreement probably extends to the notion that aspects of emotions emerge in ontogeny as a function of developmental, learning, and cultural processes. Determining when and under what circumstances they emerge seems largely a matter for empirical research, though theories differ in their predictions and in the way they describe the relevant emotional-, cognitive-, and neuro-developmental processes.

In honoring Carroll Izard’s contributions to emotion research, we discuss infant facial activity and emotion expression. We consider the debated issue of whether infants are biologically prepared to express specific emotions. We offer a perspective that potentially integrates differing viewpoints on infant facial expression of emotion. Specifically, we suggest that evolution has prepared infants with innate action readiness patterns, which are crucial for early infant–caregiver social interaction, and in the course of social interaction specific facial configurations acquire functional significance, becoming (...) associated with specific emotions. Research has not confirmed the presence of innate neurophysiological action patterns that map onto discrete emotions but evidence indicates that the possibility has not been ruled out. (shrink)

In this article, we review empirical evidence regarding the relationship between facial expression and emotion during infancy. We focus on differential emotions theory’s view of this relationship because of its theoretical and methodological prominence. We conclude that current evidence fails to support its proposal regarding a set of pre-specified facial expressions that invariably reflect a corresponding set of discrete emotions in infants. Instead, the relationship between facial expression and emotion appears to be more complex. Some facial expressions may have different (...) meanings in infants than in children and adults. In addition, nonemotion factors may sometimes lead to the production of “emotional” facial expressions. We consider alternative perspectives on the nature of emotion and emotional expression in infancy with particular focus on differentiation and dynamical systems approaches. (shrink)

A comparison of the literatures on how infants represent generic object classes, gender and race information in faces, and emotional expressions reveals both common and distinctive developments in the three domains. In addition, the review indicates that some very basic questions remain to be answered regarding how infants represent facial displays of emotion, including (a) whether infants form category representations for discrete classes of emotion, (b) when and how such representations come to incorporate affective meaning, (c) the developmental trajectory for (...) representation of emotional expression at different levels of inclusiveness (i.e., from broad to narrow or narrow to broad?), and (d) whether there is superior discrimination ability operating within more frequently experienced emotion categories.
