This chapter discusses neurophysiological aspects of dynamics, including gaze, attention, and vocal signals during the perception of expressions. A link is established between the perception of facial dynamics and vocalization after examining behavioral and electrophysiological evidence. The similarity between eye-movement patterns of rhesus monkeys viewing dynamic vocalizing faces and human eye-movement patterns established a relationship between dynamic visual and vocalization behaviors for both monkeys and humans. Mimicry, which takes place at multiple levels of abstraction, plays a role in the perception of speech as it is triggered by the gaze and perception of expression. Dynamic social and nonsocial environmental cues have an impact on the importance of an emotional signal and the neural activity initiated by it.Less
