Effect of oxytocin vs. placebo on tapping speed.
(a) Mean inter-tap interval (ITI), during tapping to computer, bidirectional and unidirectional tapping. *Indicates a significant contrast at p < 0.05, ** at p < 0.001. Error bars represent standard error of the mean. (b) Example of tapping dyad given oxytocin during bidirectional tapping, showing gradual increase in tapping speed. (c) Example of tapping dyad given placebo during bidirectional tapping, showing little change in tapping speed over time.
