The eyes have it! Reflexive orienting is triggered by nonpredictive gaze
TLDR
In this article, normal subjects were presented with a simple line drawing of a face looking left, right, or straight ahead, and a target letter F or T then appeared to the left or the right of the face.Abstract:
Normal subjects were presented with a simple line drawing of a face looking left, right, or straight ahead. A target letter F or T then appeared to the left or the right of the face. All subjects participated in target detection, localization, and identification response conditions. Although subjects were told that the line drawing’s gaze direction (the cue) did not predict where the target would occur, response time in all three conditions was reliably faster when gaze was toward versus away from the target. This study provides evidence for covert, reflexive orienting to peripheral locations in response to uninformative gaze shifts presented at fixation. The implications for theories of social attention and visual orienting are discussed, and the brain mechanisms that may underlie this phenomenon are considered.read more

The distributed human neural system for face perception.
TL;DR: A model for the organization of this system that emphasizes a distinction between the representation of invariant and changeable aspects of faces is proposed and is hierarchical insofar as it is divided into a core system and an extended system.

Human neural systems for face recognition and social communication.
TL;DR: Of regions in the extended system for face perception, the amygdala plays a central role in processing the social relevance of information gleaned from faces, particularly when that information may signal a potential threat.

Distinct representations of eye gaze and identity in the distributed human neural system for face perception
Elizabeth Hoffman,James V. Haxby +1 more
TL;DR: Perception of face identity and eye gaze in the human brain was mediated more by regions in the inferior occipital and fusiform gyri, and perception ofEye-gaze perception seemed to recruit the spatial cognition system in the intraparietal sulcus to encode the direction of another's gaze and to focus attention in that direction.

Gaze cueing of attention: visual attention, social cognition, and individual differences.
TL;DR: This review aims to provide a comprehensive overview of past and current research into the perception of gaze behavior and its effect on the observer, including gaze-cueing paradigm that has been used to investigate the mechanisms of joint attention.

Distributed and interactive brain mechanisms during emotion face perception: Evidence from functional neuroimaging
TL;DR: Hemodynamic and electrical neuroimaging results indicating that activity in the face-selective fusiform cortex may be enhanced by emotional (fearful) expressions, without explicit voluntary control, and presumably through direct feedback connections from the amygdala are reviewed.

Orienting of attention
TL;DR: This paper explores one aspect of cognition through the use of a simple model task in which human subjects are asked to commit attention to a position in visual space other than fixation by orienting a covert mechanism that seems sufficiently time locked to external events that its trajectory can be traced across the visual field in terms of momentary changes in the efficiency of detecting stimuli.
