Something Old, Something New: Leveraging What We Know to Optimize New Directions in Emotion Development Research

摘要

The 3 papers by Hammond and Drummond (2019), LoBue and Adolph (2019), and Stern, Botdorf, Cassidy, and Riggins (2019) bring into focus some of the exciting and promising new directions emerging in the field of emotional development. This commentary urges researchers moving in these new directions to leverage what is already known about emotional development to inform future predictions and interpretations, as well as to remain mindful of the thorny but essential questions surrounding the conceptualization, measurement, and interpretation of emotions. These points are illustrated with a focus on 2 specific topics. The first concerns how we conceptualize positive and negative emotions and what we might predict about their respective psychological and behavioral effects. The second concerns what should (not) count as evidence of an emotion in infants and young children and highlights the importance of converging evidence across methods and measures as well as of validating measures. This extends to the study of emotional mechanisms such as empathy and sympathy. Considering these questions carefully at this juncture has the potential to make the future study of emotional development all the more fruitful and effective.
