Faces contain a wealth of social information.
Mouth shapes which accompany articulation may also assist in comprehending speech. Even though these different types of perceptual analysis may be applied to one and the same face stimulus, the perceptual processes which compute identity, emotion, and facial speech have traditionally been thought to be functionally independent from one another. This project seeks to delineate more precisely the conditions in which the perception of different social signals from the face is independent or interdependent. Asymmetric relationships among perceptions of facial identity, emotion, and facial speech. Modular versus integrated perception of speech and identity in moving faces.
