Parametric integration of visual form across saccades
Through saccadic eye movements, the retinal projection of an extrafoveally glimpsed object can be brought into foveal vision quickly. We investigated what influence visual detail collected before the saccade exerts on the postsaccadic percept. Participants were instructed to saccade towards a peripheral stimulus, and to indicate on a continuum of ellipses with varying aspect ratios which exact ...
متن کاملFeature integration across parts in visual search.
In the present study, participants searched for a conjunction of color and orientation either from the same part of an object (same-part display), or from different parts of an object (different-part display). While no difference was found between the two display conditions in single feature searches, conjunction search in the same-part display was significantly faster than that in the differen...
متن کاملCortical Integration of Contextual Information across Objects
Recognizing objects in the environment and understanding our surroundings often depends on context: the presence of other objects and knowledge about their relations with each other. Such contextual information activates a set of medial lobe brain regions, the parahippocampal cortex and the retrosplenial complex. Both regions are more activated by single objects with a unique contextual associa...
متن کاملVisual masking and visual integration across saccadic eye movements.
The visual world appears unified, stable, and continuous despite rapid changes in eye position. How this is accomplished has puzzled psychologists for over a century. One possibility is that visual information from successive eye fixations is fused in memory according to environmental or spatiotopic coordinates. Evidence supporting this hypothesis was provided by Davidson, Fox, and Dick (1973)....
متن کاملAccumulation of visual information across multiple fixations.
Humans often redirect their gaze to the same objects within a scene, even without being consciously aware of it. Here, we investigated what type of visual information is accumulated across recurrent fixations on the same object. On each trial, subjects viewed an array comprised of several objects and were subsequently asked to report on various visual aspects of a randomly chosen target object ...
