Adaptive deployment of spatial and feature-based attention before saccades
What you see depends not only on where you are looking but also on where you will look next. The pre-saccadic attention shift is an automatic enhancement of visual sensitivity at the target of the next saccade. We investigated whether and how perceptual factors independent of the oculomotor plan modulate pre-saccadic attention within and across trials. Observers made saccades to one (the target...
متن کاملFeature-based attention across saccades and immediate postsaccadic selection.
Before each eye movement, attentional resources are drawn to the saccade goal. This saccade-related attention is known to be spatial in nature, and in this study we asked whether it also evokes any feature selectivity that is maintained across the saccade. After a saccade toward a colored target, participants performed a postsaccadic feature search on an array displayed at landing. The saccade ...
متن کاملFeature-based effects in the coupling between attention and saccades.
Previous research has demonstrated that prior to saccade execution visual attention is imperatively shifted towards the saccade target (e.g., Deubel & Schneider, 1996; Kowler, Anderson, Dosher, & Blaser, 1995). Typically, observers had to make a saccade according to an arrow cue and simultaneously perform a perceptual discrimination task either at the saccade endpoint or elsewhere on the screen...
متن کاملThree sides of a coin.
Any neutral observer of humanity might come to the conclusion that most adults in the developed world have a range of serious addiction problems. Young people often begin to explore the effects of alcohol, nicotine, cannabis and other drugs for social and psychological reasons, continuing their use of their preferred narcotic into adult life. In adults, the cocktail is enhanced by the use of as...
متن کاملControl of spatial and feature-based attention in frontoparietal cortex.
Visual attention selects task-relevant information from scenes to help achieve behavioral goals. Attention can be deployed within multiple domains to select specific spatial locations, features, or objects. Recent evidence has shown that voluntary shifts of attention in multiple domains are consistently associated with transient increases in cortical activity in medial superior parietal lobule,...
