The purpose of this study was to clarify the interaction between positional image and action. Ss were required to project positional image of a specific part of their body through pointing action. It was assumed that the changes of posture, and correct and false feedbacks would have different effects on the process. The main results were as follows: (a) positional image (ID) was not changed in ordinal standing posture, while the stabilty of positional image disappeared in one-leg standing postures, especially in 2 contralateral postural patterns, and (b) in correct feedback, pointed positional images were closed to the real position. In false feedback, the pointed positional images were more distant from the real position, and were closed to the false position except in left ipsilateral postural pattern.
