项目摘要

Microgenetic process of perception can be observed when the perceptual situation is eliminated with the stimulus ambiguous, the illumination dark, the presentation time short, etc. In this sense, the perception by aged people or people with eye disease shows the microgenetic process. The purpose of this research was to simulate the stereoscopic perception of those aged or sick.The presentation time of stereoscopic perception of size and distance was eliminated. The procedure was adaptation / aftereffect, which the investigator has been using. during the adaptation, two squares with equal retinal size but with binocular disparity were tachistoscopically exposed repeatedly. If the size constancy appears, the distant square should be perceived to be larger. In the aftereffect phase, two squares with equal retinal size but without binocular disparity were tachistoscopically exposed repeatedly. If the aftereffect occurs, the perception should be reverse to that appeared in the adaptation. The subjects were university students with normal or corrected visual acuity.Among 100 subjects, only a half of them reported size constancy in the adaptation. And, very small number of the subject reported the predicted aftereffect. The exposure time shorter than 6s was not enough for stereoscopic p adaptation. However, a small part of subjects reported the predicted microgenetic process of adaptation / aftereffect.These results were not sufficient to use as a reference for comparisons with aged conditions or disease conditions. More analysis of microgenetic time conditions for stereoscopic size constancy and aftereffect is necessary.

当知觉情境在刺激模糊、光照暗、呈现时间短等条件下被消除时，可以观察到知觉的微发生过程。从这个意义上讲，老年人或眼病患者的知觉表现为微发生过程。本研究的目的是模拟老年人和病人的立体知觉，消除对大小和距离的立体知觉的呈现时间。程序是适应/后效，调查人员一直在使用这种程序。在适应过程中，视网膜大小相等但双眼视差的两个正方形在速测镜下重复暴露。如果出现大小恒定，则应认为远处的正方形更大。在后遗症阶段，两个视网膜大小相等但没有双眼视差的正方形在速测镜下重复曝光。如果出现后遗症，这种感觉应该与改编中出现的感觉相反。受试者是视力正常或矫正视力正常的大学生。在100名受试者中，只有一半的人报告了适应过程中的大小恒定。而且，极少数受试者报告了预测的后遗症。曝光时间短于6s不足以进行立体p适应。然而，一小部分受试者报告了预测的适应/后遗症的微遗传过程。这些结果不足以作为与老年条件或疾病条件进行比较的参考。有必要对立体尺寸恒定和后效的微发生时间条件进行更多的分析。
