Humans use the direction of eye gaze and facial identity to make important social judgments. We carried out the first measurements of spatial frequency (SF) tuning for judgments of eye gaze, and compared SF tuning for judgments of facial identity and eye gaze. In Experiment 1, participants discriminated between leftward and rightward shifts of gaze, or between two male faces or two female faces...

OBJECTIVE The aim of this study was to examine eye gaze patterns between patients and physicians while electronic health records were used to support patient care. BACKGROUND Eye gaze provides an indication of physician attention to patient, patient/physician interaction, and physician behaviors such as searching for information and documenting information. METHODS A field study was conduct...

The direction of gaze automatically and exogenously guides visual spatial attention, a phenomenon termed as the gaze-cueing effect. Although this effect arises when the duration of stimulus onset asynchrony (SOA) between a non-predictive gaze cue and the target is relatively long, no empirical research has examined the factors underlying this extended cueing effect. Two experiments compared the...

The ability to adjust the amplitude of gaze shifts in response to persistent visual errors ("gaze adaptation") has been investigated primarily by introducing visual errors at the end of saccades produced by head-restrained primates. Very little is known about the behavior and neural mechanisms underlying gaze adaptation when the head is free to move. We tested alternative hypotheses about the s...

PURPOSE The purpose of the study was to investigate the changes in axial length occurring with shifts in gaze direction. METHODS Axial length measurements were obtained from the left eye of 30 young adults (10 emmetropes, 10 low myopes, and 10 moderate myopes) through a rotating prism with 15° deviation, along the foveal axis, using a noncontact optical biometer in each of the nine different ...

Monitoring gaze shifts is important for social interactions. The direction of gaze can reveal intentions and help to predict future actions. Here we examined whether behavioural and neural responses to gaze shifts were modulated by the social context of the gaze shift in two linked experiments. Two faces were presented, one gazing directly at the subject (the 'social' face) and one with averted...

Human eye-gaze is a powerful stimulus, drawing the observer's attention to places and objects of interest to someone else ('eye-gaze following'). The largely homogeneous eyes of monkeys, compromising the assessment of eye-gaze by conspecifics from larger distances, explain the absence of comparable eye-gaze following in these animals. Yet, monkeys are able to use peer head orientation to shift ...

Eye-movements have long been considered a problem when trying to understand the visual control of locomotion. They transform the retinal image from a simple expanding pattern of moving texture elements (pure optic flow), into a complex combination of translation and rotation components (retinal flow). In this article we investigate whether there are measurable advantages to having an active fre...

Some people maintain direct, face-to-face contact during interaction. whereas others avert their gaze or turn their face while interacting. Research on individual differences in gaze avoidance. while sparse. falls into two areas. One concerns the personality and psychopathology correlates of gaze aversion, and the other concerns social judgments made of people who avert their gaze during intera...
