A left visual field advantage in perception of gaze direction.

چکیده
Previous work has found a left visual field (LVF) advantage for various judgements on faces, including identity and emotional expression. This has been related to possible right-hemisphere specialisation for face processing, and it has been proposed that this might reflect configural processing. We sought to determine whether a similar LVF advantage may also exist for gaze perception. In two experiments, normal adult subjects made judgements for seen gaze direction (left, right or straight). To assess how visual field may influence perception of gaze direction, eye stimuli were briefly presented unilaterally or bilaterally. In the latter case, the gaze direction of the two seen eyes could be congruent or incongruent (i.e. the two eyes could gaze in the same or different directions). For unilateral displays, performance was more accurate for LVF stimuli than RVF. With bilateral incongruent gaze, the LVF eye influenced judgements more strongly than the RVF eye. No such LVF advantage was found in a control experiment, in which subjects judged pupil size for similar eye stimuli. Taken together, these results reveal a LVF advantage for perception of gaze direction. Since only the eye region was visible, our results cannot be due to a LVF bias in processing the entire face context. Instead they suggest lateralisation specifically in processing the direction of seen gaze.

(Un-) coupling gaze and attention outside central vision.
In normal vision, shifts of attention and gaze are tightly coupled. Here we ask if this coupling affects performance also when central vision is not available. To this aim, we trained normal-sighted participants to perform a visual search task while vision was restricted to a gaze-contingent viewing window ("forced field location") either in the left, right, upper, or lower visual field. Gaze d...
متن کاملModulation of visual perception by eye gaze direction in patients with spatial neglect and extinction.
Parietal neurons have retinotopic receptive fields whose response is modulated by eye gaze signals. We examined the role of eye position and eye movement direction on visual extinction in three patients with parietal damage and left neglect, characterized by impaired perception of contralesional field stimuli despite intact visual cortex. Patients tracked a horizontally moving fixation point, w...
متن کاملThe effect of adding gaze direction recognition to stabilizing exercises on pain, muscular endurance and proprioception women with chronic non-specific neck pain
Aims and background: Gaze direction recognition is one of the new treatments method for neck pain. The positive effects of stabilization exercises in various studies on neck pain have also been confirmed. Therefore, the aim of this study was to investigate the effect of adding a gaze direction recognition program to common stabilizing exercises on neck pain intensity, muscular endurance and pro...

Objective: In order to identify users’ visual attention to left- and right-aligned menus on web pages, fixation count index (FCI) was assessed for both left and right menus using eye tracker to determine which menu is preferred by users in terms of visual attention. Methodology: In total, 116 pages with their menus aligned to left or right, classified into three groups, namely Persian pages, En...
متن کاملAre you looking at me? Neural correlates of gaze adaptation.
Eye gaze is an important social signal, and humans can accurately determine gaze direction in others. Recently, dramatic adaptation effects on gaze perception were shown, in which the perception of small gaze deviations to the adapted direction is diminished. We compared participants' perceptions of gaze direction before and after adaptation to the left or right gaze, and examined event-related...
