Before revision:  We conducted a within-subjects experiment in which 44 subjects performed a simple interaction task with objects , using two physics simulation conditions while scaled down by a factor of ten in a virtual reality application. Although both conditions gave the visual impression of a scaled-down user interacting in a normal-sized environment, the physics conditions affecting the objects were different by simulating either correct behavior at that scale, or incorrect behavior similar to as if a normal sized user was interacting in a world that had been scaled up instead .
