Abstract
The impact of John Lanzetta's emotion research on our understanding of the interplay between psychological and physiological processes in emotion is examined. Lanzetta's work in two areas is reviewed along with related work by others. The first area concerns the biological substrates of empathy. Here Lanzetta studied emotional contagion, and in particular the conditions under which viewing another person's emotions can cause expressive and physiological changes in the observer. The second area concerns the facial modulation of emotion. Here Lanzetta studied the capacity of voluntary facial expression to alter the physiological and subjective aspects of emotion. The article closes with a personal reflection on Lanzetta as a scientist and as a person.
