Behavioural data of training sessions for Experiments 1 and 2.

<p>T-tests for Experiment 2 indicate whether the differences between Session 1 and 2 were reliable (t-values larger than the critical t-value with< = .05 are underlined). All latencies are in ms. DV = dependent variable. RT = reaction time in ms (RT 1 = RT for first response; RT 2 = RT for second response on double-signal trials). Stop-signal reaction times (SSRT) were estimated using the integration method <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0070155#pone.0070155-Verbruggen5" target="_blank">[38]</a>.
