Summary image analysis in Study 3. Average images show mean pixel intensities across images in each category, separately for high performers (left), low performers (right), and veridical categories (center). Difference images are subtractions of pixel intensity (mask minus face; rescaled for visualization). Lighter colors indicate larger differences. Note the light region around the eye in the veridical difference image. The y-axis shows 30 horizontal image slices. Correlations between difference images (gray bars) are shown for each image slice. The largest discrepancy between high and low performers is shown at Slice 15 (black bars). High performers closely tracked categorial differences in this region. Low performers did not
