Table 1 Experimental conditions and matching task. In experiment 1 (the joint condition), two participants performed the task on separate keyboards. Each participant responded only to their assigned color (red or green) in the task (go trials). In this example, their names and a neutral name were assigned to correspond to three shapes (square, triangle, and circle), which participants had to memorize for the name-shape matching task. In experiments 2, 3, 4, and 5 (individual condition), the other participant waited outside the room. Similarly, participants responded only to their assigned color (go trials) but not the other color (no-go trials). In experiments 2, 4, and 5, the participants briefly met the partners without any verbal communication, while in experiment 3, the participants never met the partners. Experiment 5 was a control experiment to replicate experiment 4 with counterbalanced stimuli
