Judgements of synchrony between a drummer’s movements and produced sound have been shown to be very little affected by a variety of degradations of visual information. For example, observing drumming actions from different viewpoints was found to affect sensitivity to asynchrony very little (Arrighi, Alais & Burr, 2006). Here we demonstrate that occlusion of information concerning the contact between drumhead and drumstick strongly affects sensitivity to asynchrony. Six participants with no music experience gave audiovisual simultaneity judgements to three different drumming point-light displays. These included: 1) shoulder-elbow-wrist-hand-grip-tip of the drumstick and the drumhead as a line (SEWHGTD); 2) tip of the drumstick and drumhead as a line (TD); shoulder-elbow-wrist (SEW). The presentation of the three display conditions were counterbalanced across participants and each condition was run in a different day. Each one of the conditions consisted of 20 repetitions of the display played at 3 tempos X 9 Stimulus Onset Asynchrony. The results showed that sensitivity to asynchrony was the same when the contact between drumstick and drumhead was presented (SEWHGTD and TD), while was strongly reduced when only the arm information was presented (SEW).
