Günther Knoblich studies how people perceive actions and coordinate joint action. His experiments ask how the presence and possible actions of another person change an individual's own performance.[ref]
In a 2003 experiment with Natalie Sebanz and colleagues, the two responses of a task were distributed between two people. Each participant made only one response. The same task was also performed alone, and compared with a condition where one person made both responses. A spatial stimulus-response compatibility effect appeared when the one-response task was shared with another participant, resembling the effect in the ordinary two-response task.[ref]

This supplied evidence that another person's available action could enter the organization of one's own response. The comparison was informative because the required individual response could be held constant while the social arrangement changed. A behavioural compatibility effect supports a functional account of action representation; it does not by itself identify a particular neuron type or prove that every possible social context uses one mechanism.
