Behavioral data for the stop-signal task

Reaction time [Go success] (ms)	457.7 ± 52.4
SSD (ms)	237.1 ± 62.9
SSRT (ms)	208.9 ± 31.7
Correct response rate [Go] (%)	98.7 ± 1.9
Correct response rate [Stop] (%)	49.9 ± 1.6
Reaction time [Stop failure] (ms)	426.1 ± 50.9
Reaction time [Stop failure|shorter SSDs] (ms)	395.5 ± 50.0
Reaction time [Stop failure|longer SSDs] (ms)	457.1 ± 56.7

Behavioral data for the stop-signal task under fMRI scanning (mean ± SD). Shorter/longer SSDs indicate trials with shorter/longer SSDs than median SSD.
