Beschreibung:Keeping visual space constant across movements of the eye
and head is a not yet fully understood feature of perception.
To understand the mechanisms that update the internal
coordinates of space, research has mostly focused on eye
movements. However, in natural vision, head movements
are an integral part of gaze shifts that enlarge the field
of vision. Here, we directly compared spatial updating for
eye and head movements. In a virtual reality environment,
participants had to localize the position of a stimulus across
the execution of a gaze shift. We found that performing head
movements increased the accuracy of spatial localization. By
manipulating the speed of the visual scene displacement that
a head movement produced, we found that spatial updating
takes into account the sensorimotor contingencies of vision.
When we presented gaze-contingent visual motion, subjects
overestimated the position of stimuli presented across gaze
shifts. The overestimation decreased if subjects were allowed
to perform eye movements during the head movement.
We conclude that head movements contribute to stabilizing
visual space across gaze shifts and that contingencies of
head movements, rather than being cancelled, facilitate the
updating
