Distinct Contributions to Facial Emotion Perception of Foveated versus Nonfoveated Facial Features

Foveated stimuli receive visual processing that is quantitatively and qualitatively different from nonfoveated stimuli. At normal interpersonal distances, people move their eyes around another's face so that certain features receive foveal processing; on any given fixation, other features therefore project extrafoveally. Yet little is known about the processing of extrafoveally presented facial features, how informative those extrafoveally presented features are for face perception (e.g., for assessing another's emotion), or what processes extract task-relevant (e.g., emotion-related) cues from facial features that first appear outside the fovea, and how these processes are implemented in the brain.
