Two experiments tested the effect of context on figure perception. Subjects were shown rapid sequences of three figures: a prime, a whole, and a part. They were asked to decide if the third figure was a part of the second (Experiment 1) or if the second and third figures were the same or different with respect to a particular angle (Experiment 2). The prime served to establish a context for stimuli that followed to be compared. Priming had influence on the part-whole comparison in Experiment 1, but not on the local comparison in Experiment 2. The results of Experiment 1 were interpreted as evidence for a role of prior information in perceptual organization. Experiment 2 showed that the task must require an integrative perceptual organization strategy for the priming effects to occur.
两项实验测试了背景对图形感知的影响。向受试者展示三个图形的快速序列：一个启动图形、一个整体图形和一个部分图形。要求他们判断第三个图形是否是第二个图形的一部分（实验1），或者第二个和第三个图形在特定角度上是相同还是不同（实验2）。启动图形用于为后续要比较的刺激建立背景。启动对实验1中的部分-整体比较有影响，但对实验2中的局部比较没有影响。实验1的结果被解释为先前信息在知觉组织中起作用的证据。实验2表明，任务必须需要一种整合的知觉组织策略才能产生启动效应。
