Observers were instructed to point with their right arm to a mirror image of their left shoulder. Instead of pointing to the target with their real arm, they occluded the target with their mirror-imaged finger, and their real finger pointed off to the left side of the target, facts that came as a surprise to them in debriefing. The occlusion by a mirror image finger was not done to avoid double images, since it occurred in monocular conditions. That it is due to planning before pointing can be inferred from the fact that it occurred in blindfolded conditions.

D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
