Autokinetic movement and inverted vision.

It was considered that inverted vision could influence the condition of the subject's relative framework. The aim of this study was to investigate whether autokinetic movement observed during inverted vision might differ from that in normal vision. One subject wearing inverting spectacles and another one subject in normal vision observed autokinetic movement for five days. The results showed that directional changes increased with the time spent in visual inversion, while in normal vision such tendency was not observed. One speculative interpretation was suggested in terms of subject-related framework.
