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.
When you flick a light switch and a light turns on, you feel a sense of agency or control over the illumination of the light. How does this feeling come about, and what happens to it if you have to coordinate with a partner to turn on the lightbulb? How would you know which of your actions caused the lightbulb to come on? We are currently investigating whether people distinguish between their own and a partner’s contribution to achieving a shared goal, and whether people develop a sense of shared agency – the feeling that “we turned on the light together” – when they engage in joint actions.
