Table 1.

Mean ± SEM for false alarms, precue response rate, and hits at baseline.

Line	n	False Alarms	Precue Response Rate (responses/s)	Hits
HS	32	15.43 ± 0.68	0.11 ± 0.01	20.20 ± 1.12
HDID-1	27	13.75 ± 0.62	0.13 ± 0.01	16.86 ± 0.93*
HDID-2	31	15.84 ± 0.76	0.12 ± 0.02	21.28 ± 1.06

Note. The maximum number of false alarms and hits is 30, determined by the total number of No-Go and Go trials/session.
