Body Balance Activity and Perception

Abstract

Thirty-five Ss were tested on a specially constructed force platform for body balance activity resulting from visual perceptions of 10 simple line drawings. No relationship was found between direction of movement on the platform and the direction depicted by the line drawings. There was no difference between body balance activity resulting from perceiving a stimulus as being in active motion and body balance activity present during a control period. There was significantly less body balance activity present when a stimulus figure was perceived as not moving than during the non-stimulus control period. When a stimulus figure was perceived as being in a postural position, there was a significant difference between body balance activity present during that perception and body balance activity present during the non-stimulus control period.
