FIGURE 1.

Schematic illustration of the procedures. (A) The experimental setup of the interaction context used in Experiment 1. (B) The experimental setup of the individual context used in Experiment 2. Notably, in the interaction context, two participants were arranged to sit next to someone of the same sex or the opposite sex and to complete the task together. One was responsible for performing the flanker task (performer), and the other was responsible for observing the partner’s performance (observer). They exchanged their roles after completing one block. The cross fixation (+) cued participant A as the performer, and the asterisk (*) cued participant B as the performer. In the individual context, the participant completed the task alone.
