Illustration of methods and results from Henke et al. (2003b). (A) Illustration of the conditions used during encoding and the masking procedure that renders the stimuli invisible. Two encoding conditions were used in the experiment. In the experimental condition a face was presented along with the name of a particular profession and in the control condition the face was presented alone. During the supraliminal test phase (i.e., no masking), participants made a button-press response indicating whether the person depicted by the face was an academic or an artist. (B) Illustration of subliminal learning effects evident during performance of the incidental memory test. Participants responded more quickly when they correctly guessed the occupational category associated with a face-profession pair seen during subliminal encoding than when they got the categorization response incorrect. No such facilitation was seen in the control condition, which confirmed that this difference was not merely a consequence of certain faces being better matched to one category over the other. (C) Activity differences in the right hippocampus (and perirhinal cortex) sensitive to subliminal encoding of face-occupation pairs (left), and activity differences in the right hippocampus (and perirhinal cortex) that were correlated with the response time differences shown in (B).
