Experimental conditions and results of the left-right walking direction discrimination experiment.

Abstract

<p>(A) Walking directions of stereo point-light walkers, defined by disparity cues (Purple - toward; Green - away), deviated slightly from the observer’s line of sight (L - Left; R - Right). (B) Left-right discrimination thresholds of toward and away conditions plotted for individual observers (the experimental group) and as group averages (the experimental and the control groups). The threshold of the toward condition was significantly lower compared with that of the away condition. Error bars indicate one SEM. **<i>p</i><.01.</p
