翻译后摘要:摘要时间背景,或适应,深刻地影响视觉感知。尽管适应效应的强度和普遍性,它们在视觉处理中的功能作用仍然不清楚。空间背景的影响及其功能作用得到了更好的理解:这些影响突出了与周围环境不同的特征,并决定了刺激的显着性。空间和时间背景的感知和生理效应的相似性提高了它们具有相似功能的可能性。因此,我们测试的可能性,适应可以提高刺激的显着性。我们测量了延长(40秒)适应反相光栅在搜索任务中的性能的影响,其中目标被定义为相对于背景的分心物的方向偏移。我们发现,对于小方向偏移的目标,适应减少了反应时间,减少了寻找目标的扫视次数。我们的研究结果提供的证据表明,适应可能会突出功能,不同的时间背景下,他们被嵌入。
Abstract:Abstract Temporal context, or adaptation, profoundly affects visual perception. Despite the strength and prevalence of adaptation effects, their functional role in visual processing remains unclear. The effects of spatial context and their functional role are better understood: these effects highlight features that differ from their surroundings and determine stimulus salience. Similarities in the perceptual and physiological effects of spatial and temporal context raise the possibility that they serve similar functions. We therefore tested the possibility that adaptation can enhance stimulus salience. We measured the effects of prolonged (40 s) adaptation to a counterphase grating on performance in a search task in which targets were defined by an orientation offset relative to a background of distracters. We found that, for targets with small orientation offsets, adaptation reduced reaction times and decreased the number of saccades made to find targets. Our results provide evidence that adaptation may function to highlight features that differ from the temporal context in which they are embedded.
