We investigated how social goals are incorporated into action plans. In Experiment 1 participants grasped an object and located it within a container (blocked trials). In 20% of trials a human agent seated next to the participant unfolded the hand to ask for the object (perturbed trials). In Experiments 2 & 3 the agent was replaced by a robotic device or performed an action not conveying a social request, respectively. Results indicate that motor response varied depending on the nature of the perturbation. Only human gestures conveying a social request modified pre-planned action by on-line integration of other’s actions.

Abstract
We investigated how social goals are incorporated into action plans. In Experiment 1 participants grasped an object and located it within a container (blocked trials). In 20% of trials a human agent seated next to the participant unfolded the hand to ask for the object (perturbed trials). In Experiments 2 & 3 the agent was replaced by a robotic device or performed an action not conveying a social request, respectively. Results indicate that motor response varied depending on the nature of the perturbation. Only human gestures conveying a social request modified pre-planned action by on-line integration of other’s actions.
