Abstract： During social communication, eyes gaze indicates the focus of people's attention. There are two types of gaze cue: direct gaze (straight) and averted gaze (left or right), which have different social functions. Previous researchers assume that gaze perception involves two different processing stages. The first stage refers to earlier visual feature analysis of eyes such as luminance contrast and geometry of white sclera and iris. The second stage involves the perceptual integration of eyes’ features and the extraction of gaze direction. However, this assumption ignores the differences in processing mechanism between direct gaze and averted gaze. Other researchers hypothesize that perception of direct gaze is mediated by a fast-track pathway via subcortical face processing route. Direct gaze perception has characteristics of automatic process, such as capturing attention and being processed unconsciously. Its automaticity shows that direct gaze has a processing advantage over averted gaze. We inferred that direct gaze perception was independent of attentional resources, while averted gaze perception required more attentional resources. The present study aimed at investigating how attentional resources affect perception of averted and direct gaze.
