Behavioral results for the CRT task and SST (original and controlled)

		SST original		SST controlled
Trial type	CRT	Run 1	Run 2	Run 1	Run 2
Median Go RT (ms)	411 ± 16	447 ± 14	448 ± 14	462 ± 17	453 ± 13
SD Go RT (within subjects)	69 ± 8	87 ± 5	83 ± 5	100 ± 8	90 ± 9
Median Continue RT (ms)	NA	NA	NA	502 ± 17	486 ± 17
Accuracy on Go trials, %	97.7 ± 0.4	98.3 ± 0.4	98.7 ± 0.4	98.2 ± 0.5	98.5 ± 0.3
Accuracy on Continue trials, %	NA	NA	NA	97.0 ± 0.9	98.2 ± 0.6
Accuracy on Stop trials, %	NA	48.3 ± 0.7	50.1 ± 0.7	50.9 ± 0.7	50.9 ± 0.7
SSRT (ms)	NA	231 ± 11	227 ± 11	222 ± 13	220 ± 11

Average of the median speed of response to Go trials (Go RT), median speed of response to continue trials (Continue RT), SSRT, and accuracy on Go, Continue, and Stop trials are reported (±SEM). Percentage accuracy is estimated by dividing the number of correct trials (Go, Continue, or Stop) by the total number of each trial type. The within-subject SD is also reported for Go RT. SSRT was calculated for each subject and each run by subtracting the critical SSD from the median Go RT. NA, not applicable.
