进行了一项调查，以量化感官差异检查条件下形成的轮廓曲率的经验。使用了N = 80名男性和女性本科生。实验Ss手指跟踪一个水平的直线边缘，同时通过弯曲诱导透镜观察肢体运动。控制Ss检查边缘单峰，无论是通过视觉（扭曲）或本体感受。而不是依靠口头报告，所有的学生被要求匹配他们的轮廓形状的印象与可调金属曲线。研究结果表明：（a）由视觉和本体感觉信息不一致所产生的轮廓形状的平均印象是弯曲的，与由扭曲的视觉信息所产生的印象没有区别;（B）单独的本体感觉检查导致对身体平直度的准确判断;（c）反应模态效应没有出现，和（d）操纵设计直接Ss注意到左轮廓形状，并在感觉差异检查不影响平均曲率匹配，但创造了相当大的变化之间的匹配。视觉捕捉的感觉组织与选择性处理解释进行了讨论。
An investigation was performed to quantify the experience of contour curvature formed under sensory discrepancy inspection conditions. N = 80 male and female undergraduates were used. Experimental Ss finger-tracked a horizontal straight edge while viewing limb movements through a curve inducing lens. Control Ss inspected the edge unimodally, either through vision (distorted) or proprioception. Rather than relying on verbal reports all Ss were required to match their impressions of contour shape with an adjustable metal curve. Findings indicated that (a) the mean impression of contour shape derived from discrepant visual and proprioceptive information was curved and did not differ from that derived from distorted visual information, (b) proprioceptive inspection alone resulted in accurate judgements of physical straightness, (c) response modality effects did not emerge, and (d) a manipulation designed to direct Ss attention to the left contour shape and during sensory discrepancy inspection did not affect mean curvature matches but created sizeable variability among matches. A sensory organization versus a selective processing interpretation of visual capture was discussed.
