Response to scrambled faces is intermediate. (A) Power spectrum averaged over the main cluster associated to the facelike pattern effect (channels with P < 0.01), for the three conditions (shaded contour indicates the SEM across subjects): the average response to scrambled faces is more similar to the response to inverted faces. (B) Single-subject FTR in the main cluster for the three conditions. Although FTR(upright) > FTR(inverted) for each subject (reflecting the highly significant statistical difference), the FTR to scrambled faces is closer to the FTR to upright faces than it is to inverted faces in 4 of 10 subjects, suggesting an intermediate response.
