(A) Experimental setup. Participants viewed stimuli presented on a screen directly in front of them. Responses were made using the right hand only. (B) Examples of stimuli used in the biological and non-biological conditions. Biological stimuli consisted of still photographs in which an actor grasped the manipulandum with their right hand using either a precision or a power grip. Actions in the non-biological condition were cued by the presentation of a red dot on the aspect of the large or small cylinder. In congruent trials, participants copied the grip and gripped the cylinder with the red dot respectively. In incongruent trials, participants performed the opposite grip or gripped the cylinder without a dot respectively.
