Cardiac response to Mixed-Reality task. Points display mean percentage change in Inter-beat Interval (IBI) from the 1st IBI recorded during each trial, across the first 10 IBIs recorded in a trial. Each graph displays cardiac data averaged across all trials within each level of delay (0ms to 594ms), and in response to self- and other-stroking. Values of 100% represent no change, while lower values represent heart rate acceleration, and higher values represent heart rate deceleration. Error bars are standard errors from the mean.
