Abstract

Adaptation to blurred or sharpened images has a large and rapid effect on perceived image focus and at longer durations has also been reported to impact acuity and blur sensitivity, but the dynamics and functional consequences of the adaptation remain poorly characterized. We tested the effects of blur adaptation on visual performance for two tasks and two adapting durations. Specifically, we measured the effects of brief (12 s) vs. prolonged (2 h) blur adaptation on visual search and discrimination performance. Our results show that adaptation improved search accuracies for novel blur levels after prolonged but not brief adapting duration, while neither duration improved blur discrimination. The improvements in visual search could reflect the role of adaptation in increasing the salience of novel properties in the visual environment.

短时和长时间模糊适应对视觉搜索和识别的影响

对模糊或锐化图像的适应对感知图像焦点具有巨大而迅速的影响，并且在更长的持续时间内也有报道影响灵敏度和模糊灵敏度，但适应的动态和功能后果仍然不清楚。我们测试了模糊适应对两个任务和两个适应持续时间的视觉表现的影响。具体来说，我们测量了短暂（12秒）和长时间（2小时）模糊适应对视觉搜索和识别性能的影响。我们的研究结果表明，在较长而不是较短的适应时间后，自适应提高了对新模糊水平的搜索精度，但持续时间都没有提高模糊识别。视觉搜索的改进可能反映了适应在视觉环境中增加新特性显著性的作用。

期刊介绍： Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
