Sample images taken from one of the 60-s videos of faces morphing from Black to White used in Study 1. Faces changed from Black at 0 s to White at 60 s; Time windows used for analysis are as indicated. Note that the start and end faces were matched on attractiveness, ear shape, and head shape, size, and position and that overall image luminance was held constant by progressively darkening the background color.
