Study 1: The purpose of Study 1 is to discern whether sensorimotor communication and self-other integration between partners during joint action, indexed by alpha-mu suppression in sensorimotor areas, are associated with a stronger tendency of the partners to remain
committed to the joint action. Participants will engage in a joint task requiring motor coordination with two different partners (both confederates).
Study 2: It requires participants and their partners to move their respective markers that are located at opposite sides of the screen (e.g., the participant's marker is on the centre-left and their partner’s marker is on the centre-right) to one of two targets stacked horizontally in the centre of the screen. Both participants and partners receive points depending on how quickly they reach the correct target.
