Adaptation improves performance on a visual search task

摘要: Temporal context, or adaptation, profoundly affects visual perception. Despite the strength and prevalence of adaptation effects, their functional role in processing remains unclear. The effects spatial context are better understood: these highlight features that differ from surroundings determine stimulus salience. Similarities perceptual physiological temporal raise possibility they serve similar functions. We therefore tested can enhance measured prolonged (40 s) to a counterphase grating on performance search task which targets were defined by an orientation offset relative background distracters. found that, for with small offsets, reduced reaction times decreased number saccades made find targets. Our results provide evidence may function embedded.
