Example stimuli from the perceptual task used in both Experiments 1 and 2 are displayed.

Stimuli included three types: (A) Full stick figure walkers, (B) bottom-half-only stick figure walkers, and (C) top-half-only stick figure walkers. Stick figure walkers were based on 3D biological motion point-light walkers consisting of 15 dots (depicting the center of major skeletal joints; see Troje, 2002, 2008) to which we added connecting lines.
