Abstract

Detection and diplopia thresholds for vertical disparities are found to decrease when the presentation time of the stimulus with disparity is increased between 20 msec and 2 sec. This result supports the following notions previously put forward in literature; (a) the human visual system embodies detection processes which reveal vertical disparities; there is no sensory fusion mechanism in this system that gradually conceals vertical disparities: (b) the detection of vertical disparity in tachistoscopically presented stimuli is not based upon the initial appearance of the stimulus with disparity.

摘要

当具有视差的刺激呈现时间在20毫秒至2秒之间增加时，垂直视差的检测阈值和复视阈值会降低。这一结果支持了文献中先前提出的以下观点：(a) 人类视觉系统包含揭示垂直视差的检测过程；该系统中不存在逐渐掩盖垂直视差的感觉融合机制；(b) 对速示呈现刺激中垂直视差的检测并非基于有视差刺激的初始外观。
