观察者错误地认为场景中点的位置被压缩到扫视的目标。然而，最近的研究表明，当离散元素（例如点）被视为矩形等统一对象时，不会发生扫视压缩。我们研究了 Kanizsa 图形（通过虚幻轮廓统一为单个感知对象的离散元素的集合）和控制矩形图形的水平与垂直压缩的大小。向参与者提供 Kanizsa 和控制图，并必须使用两种替代力选择方法来决定刺激的水平长度或垂直长度是否更长。我们的研究结果表明，大但不小的 Kanizsa 人物被认为是压缩的，这种压缩在水平维度上很大，而在垂直维度上很小或为零。与最近的发现相反，我们发现控制矩形没有扫视压缩。我们的数据表明，由于方法论的缺陷，Kanizsa 图的压缩在之前的研究中被高估了，并强调了通过多种方法研究感知现象的重要性。
Observers misperceive the location of points within a scene as compressed towards the goal of a saccade. However, recent studies suggest that saccadic compression does not occur for discrete elements such as dots when they are perceived as unified objects like a rectangle. We investigated the magnitude of horizontal vs. vertical compression for Kanizsa figure (a collection of discrete elements unified into single perceptual objects by illusory contours) and control rectangle figures. Participants were presented with Kanizsa and control figures and had to decide whether the horizontal or vertical length of stimulus was longer using the two-alternative force choice method. Our findings show that large but not small Kanizsa figures are perceived as compressed, that such compression is large in the horizontal dimension and small or nil in the vertical dimension. In contrast to recent findings, we found no saccadic compression for control rectangles. Our data suggest that compression of Kanizsa figure has been overestimated in previous research due to methodological artifacts, and highlight the importance of studying perceptual phenomena by multiple methods.
