How do individual perception, action, and cognition operate in different social contexts and how do we understand social interactions we observe in others? I will present findings from our lab (somby.ceu.edu) addressing these issues. I will start with experiments on joint action planning demonstrating that joint actions are planned in a similar way as individual actions that require coordination between different limbs. Further experiments show that joint action plans specify relations between co-actors’ individual actions. In the second part I will demonstrate that sharing a joint environment can improve joint perceptual judgments more than communicating confidence about one’s judgments to each other. Locating a target in a virtual environment yielded large joint benefits when participants viewed the environment from different perspectives. Verbally communication did not lead to any benefits. In the last part, I will present research that asked what makes observers think that individuals are committed to a joint action. Using web-based experimentation we found that perceiving a higher degree of coordination in a joint action is sufficient to make observers think that individuals are more committed to a joint action. I will discuss how this finding challenges traditional philosophical accounts of commitment.
