最近的研究表明，在扫视之前立即闪现的有知觉组织的物体的表面形状并没有扭曲，尽管扫视周围的闪光是错误定位的，就好像视觉空间被压缩到扫视的目标上一样。我们报道了在运动周期内闪过的Kanizsa错觉矩形的视宽度被压缩的程度与不诱导错觉矩形的对照刺激相同，而具有真实轮廓的矩形的视宽度被压缩的程度要小一些。我们的研究结果表明，视觉空间的跳变压缩过程比虚幻轮廓的插值过程完成得更快。(C) 2004 Elsevier Ltd.版权所有。
Recent studies have suggested that the apparent shape of a perceptually organized object flashed immediately before saccade is not distorted although a perisaccadic flash is mislocalized as if the visual space is compressed toward the goal of the saccade. We report that the apparent width of a Kanizsa illusory rectangle flashed in the perisaccadic period was compressed as much as that of a control stimulus that did not induce illusory rectangle, while that of a rectangle with real contour was less compressed. Our results imply that the process of saccadic compression of visual space completes faster than the interpolation process of illusory contours. (C) 2004 Elsevier Ltd. All rights reserved.
