The interJW-55 action between delay and action was marginally significant [F(1,34) = 3.6, p = 0.065], and indicated that performance improvement in delayed touch trials was present in active touch blocks [F(1,34) = 10.0, p = 0.003] but absent in passive touch blocks [F(1,34) < 1, p = 0.521]. Choices of which hand felt the more intense touch in sameintensity trials can be seen in Figure 2A. When touch on both hands or on neither hand were observed, choices between the left and the right hand were around chance (50 ). Observers were more likely to choose one of the hands in trials in which only one of the hands was seen to receive touch. Specifically, they were more likely to choose their left hand as having felt the more intense touch when they viewed touch on the left hand, and to choose their right hand as having felt the more intense touch when they viewed touch on the right hand. This tendency was only present in active touch blocks and it was particularly pronounced when felt touches were concurrent with observed touches. For all trials in which the left (right) hand was chosen as having felt the more intense touch, statistical analyses compared the frequency of trials in which touch on both hands or touch on neither of the hands was observed (collapsed data) to the frequency of trials in which touch was observed on the left (right) hand. Comparisons were made in separate repeated-measures ANOVAs for the within-subject factors touch (touch both/none vs. touch left; touch both/none vs. touch right), action (passive vs. active touch trials), and delay (concurrent vs. delayed touch trials).
