The stop-signal reaction time (SSRT) was estimated using the integration method. For SSRT [go distribution], the go RT distribution was used as an estimate of the underlying go distribution on stop trials. For SSRT [ac distribution], the ac RT distribution was used as an estimate of the underlying go distribution on stop trials (for DD strategy only). The percentage error is estimated by dividing the number of incorrect trials by the total number of the respective trial type.
