Figure 2.

Sample stimuli. (A) Displayed are two patterns of randomly moving dots with a motion coherency of 80% toward the left (left) or right (centre). In addition, static patterns of randomly assigned dots (right) with identical stimulus parameters were applied. (B) Displayed are three examples (“Running,” “Jumping,” and “Turning a Cartwheel”) of the human movements used in Experiment 2 (“Biological Motion”). Stimuli consisted of white dots placed at locations on (invisible) lines connecting the main joints of upper arm, forearm, upper leg, and lower leg and were presented on a black background (“Point-Light Motion”). (C) Displayed is a global shape (“Cross”) that consists of coherently moving dots with a direction of motion rotated 45° counter clockwise (left) or clockwise (right) from the vertical axis presented on a background of coherently moving dots rotated 45° counter clockwise from the vertical axis (“Shape-from Motion”).
