Abstract

The effect of variation of subject-stimulus distance upon under-shooting-overshooting errors in tasks involving space localization was explored. S's task was to indicate when a stimulus, which moved (in one experiment rotationally CW/CCW; in the other two linearly L to R/R to L) continuously under E's control, was aligned with the median plane of his body. In each of three independent studies (N = 16, 24, 24), it was found that magnitude of undershooting is smaller with a .6l m than with a 2.44 m distance between S and stimulus (p < .01). (18pp.)
