An investigation was performed, with the use of 60 male and female college students, to quantify the Chevreul pendulum illusory effect, the tendency of a small pendulum, when suspended from the hand and imaginatively concentrated upon, to oscillate seemingly of its own accord. By means of a time exposure photographic measurement technique, strong parametric influences of the pendulum's sinusoidal motion were isolated. It was found that the pendulum effect was enhanced when (a) attentional capacity remained undivided, (b) the amount of musculature used to suspend the pendulum was at a maximum, (c) oscillating visual and auditory external stimuli were present, and (d) females were Ss. In addition, the visual stimulus was found to be superior to its auditory counterpart. The relevance of ideomotor and visual capture interpretations of covert muscle processes in the pendulum illusion was discussed.
一项针对60名男女大学生展开的调查，旨在量化谢弗勒摆错觉效应，即当一个小摆锤悬于手中并被想象性地集中注意力时，它似乎会自行摆动的倾向。通过一种长时间曝光摄影测量技术，分离出了摆锤正弦运动的强烈参数影响。研究发现，当（a）注意力保持集中，（b）用于悬挂摆锤的肌肉量达到最大，（c）存在振荡的视觉和听觉外部刺激，以及（d）女性作为被试时，摆锤效应会增强。此外，还发现视觉刺激优于听觉刺激。讨论了摆锤错觉中隐蔽肌肉过程的动念动作和视觉捕获解释的相关性。
