The purpose of this study was to examine whether a change of perceptual framework may affect the occurrence of apparent movement. Apparent movement was observed by one subject living over four days in the prismatically inverted visual world, because this situation was considered as the operation in which the subject was forced to change the perceptual framework to adapt himself to the novel environment. Apparent movement with two points was measured in vertical and horizontal configurations before wearing and after removing the prism as well as while wearing it. Analysis showed significant effects of prism-wearing on the occurrence of apparent movement in both vertical and horizontal configurations. Although further elaboration is required, an hypothesis was suggested from the viewpoint of the loss of visual position constancy.
本研究的目的是检验感知框架的变化是否会影响似动的发生。一名受试者在棱镜倒置的视觉世界中生活了四天，在此期间观察到了似动现象，因为这种情况被视为受试者被迫改变感知框架以适应新环境的操作。在佩戴棱镜前、摘下棱镜后以及佩戴棱镜时，测量了两点在垂直和水平配置下的似动情况。分析表明，佩戴棱镜对垂直和水平配置下似动的发生均有显著影响。尽管还需要进一步阐述，但从视觉位置恒常性丧失的角度提出了一个假设。
