Effects of Peripheral Visual Field Loss on Eye Movements During Visual Search
Natural vision involves sequential eye movements that bring the fovea to locations selected by peripheral vision. How peripheral visual field loss (PVFL) affects this process is not well understood. We examine how the location and extent of PVFL affects eye movement behavior in a naturalistic visual search task. Ten patients with PVFL and 13 normally sighted subjects with full visual fields (FV...

10 Visual cognition depends critically on the moment-to-moment orientation of gaze. To change the gaze to a new location in space, 11 that location must be computed and used by the oculomotor system. One of the most common sources of information for this 12 computation is the visual appearance of an object. A crucial question is: How is the appearance information contained in the 13 photometric...
متن کاملEye movements during parallel-serial visual search.
Two experiments (one using O and Q-like stimuli and the other using colored-oriented bars) investigated the oculomotor behavior accompanying parallel-serial visual search. Eye movements were recorded as participants searched for a target in 5- or 17-item displays. Results indicated the presence of parallel-serial search dichotomies and 2:1 ratios of negative to positive slopes in the number of ...
