Figure 1. Examples of the stimuli, experimental paradigm, and block design.

Participants were shown images of themselves/their labmate, their boss/faculty member, and scrambled images of faces for 200 ms, separated by a fixation cross that lasted between 800–1200 ms (left diagram). Blocks consisted of the following three stimuli sets (right diagram): self/boss/scrambled, self/faculty/scrambled, labmate/boss/scrambled, and were performed with both left and right hands, for a total of 6 blocks. Starting response hand and stimuli sets were counterbalanced across participants.
