Table 4. Summary of Empirical Measures (in ms) for Individual Participants and Average (A) From Each Experiment.

E	P	Ignore				Stop					Diff
		RTNo	SDNo	T0p	RTNo	SDNo	T0p	% Error	RTerr	SSRT	T0p
Note. RTNo and SDNo are the mean and standard deviation of RT in the no-signal condition. T0p is the dip onset estimated from pooled distribution across all SOAs locked on signal onset (see Figure 8), except for Participant 1 in Experiment 2 for whom T0 at SOA 50 was used as this was the only SOA showing a dip. Values within brackets indicate the bootstrap 95% confidence interval. The last column indicates the observed difference in T0p between the ignore and stop instructions, along with the bootstrap 95% confidence interval on this difference. For the stop condition, the % of failed stops for each SOA and the mean error RT and SSRT across SOAs are also provided. Note that, for Experiment 3, the ignore and stop conditions are interleaved, so there is only one no-signal condition. See Appendices B–D for mean error RT, SD, and SSRT at each SOA.
