通过2个实验来确定视觉持续时间与刺激的时空分离之间的关系。第一个实验扩展了F. Efron和D. Lee以前的工作（见记录1972-10043-001）。美国国家航空航天局艾姆斯研究中心生命科学部的七名工作人员（包括笔者）在连续的方向中呈现一条单线，每条线以固定的角度和固定的时间间隔分开。s报告了似乎一起旋转的连续线的数量。旋转线的感知数量随着刺激呈现的速度呈线性增加，斜率与空间分离成正比。在第一个实验中得到的线性函数预测了第二个实验的结果，在第二个实验中，相同的s将时空变量调整到看到2条旋转线的判别阈值。总体结果表明，在显著的空间和时间变化范围内，短暂出现的刺激的可见持久性随着该刺激与较晚发生的其他刺激之间的距离而增加。（39 ref）（PsycINFO Database Record (c) 2016 APA，版权所有）
Conducted 2 experiments to determine the relationship between duration of visible persistence and temporal and spatial separation of stimuli. The 1st experiment extended previous work of F. Efron and D. Lee (see record 1972-10043-001). Seven staff members of the Life Sciences Division of the National Aeronautics and Space Administration Ames Research Center (including the author) were presented with a single line in a succession of orientations, each separated by a fixed angle and by a fixed interval of time. Ss reported the number of successive lines that appeared to rotate together. The perceived number of rotating lines increased linearly with the rate of stimulus presentation, with a slope proportional to the spatial separation. The linear functions obtained in the 1st experiment predicted the results of a 2nd experiment in which the same Ss adjusted the spatial and temporal variables to a discrimination threshold for seeing 2 rotating lines. Overall results indicate that, over a significant range of spatial and temporal variation, the visible persistence of a briefly presented stimulus increases with the distance separating that stimulus from other stimuli occurring later in time.(39 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
