Short-term memory for spatial location in goal-directed locomotion

A blind walking study was conducted to examine the nature of the representation that subjects use to guide goal-directed locomotion. Subjects walked blindfolded to targets 4,8, and 12 m away, either immediately after visual occlusion or following a 2-sec or 30-sec no-vision delay. On half of the trials, subjects were cued as to target prior to visual occlusion; on the other trials, the specific target was identified after visual occlusion, just …
