Figure 1.

Examples of apparent motion face stimulus conditions. Display changes were embedded within a continuously present Baseline condition, and these task irrelevant gaze changes were Blink, Eye Closure, Upward, Leftward. A checkerboard pattern superimposed upon the baseline condition face was presented infrequently and served as the Target stimulus. The resulting display produced an apparent motion effect where the eyes on the face were altered across the various conditions which each had a 100 ms duration, with the exception of the Blink whose duration was 33 ms. The example depicts the female face. A male face was also used in the experiment.
