In the BrAIn Lab, we study how people perform actions alone and together with other people. Current projects focus primarily on joint actions, in which two or more people coordinate their actions to achieve a shared goal, such as a musical duet, a conversation, or moving a couch from point A to point B. The links below provide more information about the types of questions we’re currently investigating.
Joint actions pose unique challenges that people acting alone do not face. One such challenge is keeping track of shared goals, or goals that can only be achieved by acting together with another person. Our research uses EEG to measure the neural signals that indicate whether or not a shared goal has been achieved. We are currently comparing neural signals in response to achieving solo versus shared goals to determine how the action monitoring system adjusts when people have to coordinate their actions with others. We are also investigating how the subjective experience of joint agency [link back to joint agency subpage] affects these neural signals.
