Fig 1.
Examples of the Face-n-Thing images with canonical upright (top) and inverted (bottom) display orientation.
The image on the left is an example of one of the least resembling a face with upright display orientation, and the image on the right is one of the most resembling a face when presented with upright orientation.
Fig 2.
Effect of inversion on the face tuning.
Mean response rate (left) and mean response time (right) of the face responses to the Face-n-Thing images with canonical (upright) and inverted display orientations in females (orange blobs) and males (violet triangles). Vertical bars represent ±SEM. Double asterisks indicate significant differences: black, gender differences, orange, display orientation effect in females, and violet, display orientation effect in males (p < 0.05). Single asterisk indicates a tendency of females to provide face response faster than males with display inversion (p = 0.079).
