Experimental procedure and behavioral result.

<p><i>A</i>) Sample trials in the experimental runs. Participants were instructed to discriminate face parts in a sequentially-presented face pair, either both with veridical face configurations (Veridical trials) or both without the configurations (Scrambled trials). The two types of trials were randomly intermixed in the runs. <i>B</i>) Behavioral performance. In the scanner, participants were more accurate (Left) and quicker (Right) in discriminating face parts in the Veridical trials than the Scrambled trials. Error bars indicate standard error of mean (s.e.m.) above and below the mean. *: <i>p</i><0.001.
