Five experiments were conducted to examine duration of visible persistence in sequences of stimuli. The basic display consisted of a point that stepped around a circular path on the face of an oscilloscope. Observers estimated the number of points seen simultaneously. Results were compared with a control condition in which the points were plotted in random order rather than sequentially. It was found that visible persistence of a point is suppressed if other points are shown nearby and after an appropriate delay. The degree of suppression depended on the spatial proximity of successive points. It was also found that both duration of visible persistence and degree of suppression increase with eccentricity in the visual field. The results are discussed in terms of two independent processes, persistence and suppression, that operate in a hierarchically antithetical relation.
进行了五项实验来研究刺激序列中可见持久性的持续时间。基本显示由一个在示波器屏幕上沿圆形路径移动的点组成。观察者估计同时看到的点数。将结果与一个对照条件进行比较，在对照条件下，点是随机排列而非顺序排列的。结果发现，如果在适当延迟后在附近显示其他点，一个点的可见持久性会受到抑制。抑制程度取决于连续点的空间接近度。还发现可见持久性的持续时间和抑制程度都随视野中的离心率增加而增加。根据两个独立的过程，即持久性和抑制，以分层对立的关系运作来讨论这些结果。
