Attention switching in depth using random-dot autostereograms: attention gradient asymmetries.
Random-dot autostereograms (RDASs) were used to investigate attention shifts along the sagittal plane in distractor-free tasks of high perceptual load. In three experiments using a same/different comparison task, the shape of the gradient over five different depths was examined and the conditions under which the gradient is and is not observed were compared. When the target set consisted of fiv...
متن کاملVisual field asymmetries in attention and learning.
It has been suggested that attentional resolution is greater in the lower than in the upper visual field. As there is no corresponding asymmetry between the areas in the primary visual cortex where the input from upper and lower visual fields is processed, an 'attentional filter' has been proposed to act in one or more higher visual cortical areas in order to constrict the availability of visua...
متن کاملDynamics of Attention in Depth Dynamics of Attention in Depth: Evidence from Multi-element Tracking
The allocation of attention in depth is examined using a multi-element tracking paradigm. Observers are required to track a predefined subset of from two to eight elements in displays containing up to sixteen identical moving elements. We first show that depth cues, such as binocular disparity and occlusion through T-junctions, improve performance in a multi-element tracking task in the case wh...
متن کاملDepth without disparity in random-dot stereograms.
Depth can be perceived in random-dot stereograms in which dots are binocularly uncorrelated, in the absence of overall positional disparity (e.g., Julesz, 1960). This phenomenon, which we have called rivaldepth, persists over a wide range of luminances, stereogram dot densities, and dot sizes. Rivaldepth is also observed with interocular uncorrelation provided by complementation and orthogonal ...
متن کاملSelective attention and attention switching: towards a unified developmental approach.
We review and relate two literatures on the development of attention in children: one concerning flexible attention switching and the other concerning selective attention. The first is a growing literature on preschool children's performances in an attention-switching task indicating that children become more flexible in their attentional control during the preschool years. The second literatur...
