Attention modulates trans-saccadic integration
With every saccade, humans must reconcile the low resolution peripheral information available before a saccade, with the high resolution foveal information acquired after the saccade. While research has shown that we are able to integrate peripheral and foveal vision in a near-optimal manner, it is still unclear which mechanisms may underpin this important perceptual process. One potential mech...
متن کاملTrans-saccadic perception.
A basic question in cognition is how visual information obtained in separate glances can produce a stable, continuous percept. Previous explanations have included theories such as integration in a trans-saccadic buffer or storage in visual memory, or even that perception begins anew with each fixation. Converging evidence from primate neurophysiology, human psychophysics and neuroimaging indica...
متن کاملSaccadic eye movements do not disrupt the deployment of feature-based attention.
The tight link of saccades to covert spatial attention has been firmly established, yet their relation to other forms of visual selection remains poorly understood. Here we studied the temporal dynamics of feature-based attention (FBA) during fixation and across saccades. Participants reported the orientation (on a continuous scale) of one of two sets of spatially interspersed Gabors (black or ...
متن کاملSelective attention and the active remapping of object features in trans-saccadic perception
When the same object is attended both before and after a saccadic eye movement, its visual features may be remapped to the new retinal position of the object. To further investigate the role of selective attention in trans-saccadic perception, the magnitude of the cross-saccadic tilt aftereffect was measured for both attended and unattended objects. The results show that both selective attentio...
متن کاملA Modal Approach to Feature-based Correspondence
We propose a novel method for performing point-feature correspondence based on a modal shape description. Introducing shape information into a low-level matching process allows our algorithm to cope easily with rotations and translations in the image plane, yet still give a dense correspondence. We also show positive results for scale changes and small skews, and demonstrate how reflectional sy...
