Introduction

We have defined emotional contagion as a multiply determined family of psychophysiological, behavioral, and social phenomena. In chapter 1, we reviewed evidence that there is a pervasive tendency automatically to mimic and synchronize expressions, vocalizations, postures, and movements with those of another person. This mimicry coordinates and synchronizes social interactions while freeing the interactants to think about other issues, such as what one or both of them are trying to achieve and what each is saying. In this chapter, we focus on another important but often overlooked consequence of mimicry: the tendency for mimicked acts to cultivate a convergence of emotions among the interactants. Thus,

Proposition 2. Subjective emotional experiences are affected, moment to moment, by the activation and/or feedback from such mimicry.

As was outlined in chapter 1, subjective emotional experience could theoretically be influenced by either:

1. the central nervous system commands that direct such mimicry/synchrony in the first place;

2. afferent feedback from such facial, verbal, or postural mimicry/synchrony; or

3. conscious self-perception processes, wherein individuals make inferences about their own emotional states on the basis of their own expressive behavior.
