Humans’ abilities to reason and think about emotion (i.e., affective cognition) is highly sophisticated. Even with limited information, humans can predict whether someone will feel amused, excited, or moved, or whether they will feel embarrassed, disappointed, or furious. How do humans acquire these abilities? This course will delve into the development of affective cognition in infancy and childhood. Topics include infants’ and children’s abilities to infer, predict, and explain emotions, the influence of family and culture in these developmental processes, and atypical development of affective cognition. Through reading classic and contemporary papers, presenting and discussing current topics, and proposing novel ideas in this research domain, students will gain an in-depth understanding of the fundamental aspects of affective cognition over the course of development.
