Participants (N = 25 dyads) are told that one mobile object is controlled by the other person and asked to click the mouse whenever they think they are in contact with the object. The task is made non-trivial by the presence of static objets and a shadow object that moves exactly the same as the other person (below). In spite of this objective ambiguity participants are able to click most frequently when in direct contact with the other person's sensor and not the shadow (far below). However, data indicates that this is not due to an individual recognition of differences in responsiveness but to the collective dynamics of the task.
We have added a new condition to the experiment where participants are at a point in the normal interaction presented with a non-contingent recording of the movements of the other person during a previous period in the interaction. Analysis is still in progress.
