Table 2. Group means and standard deviations for behavioural performance parameters on the emotional Go/No-Go task.

	Patients		Controls
	Inhibit negative- respond to neutral	Inhibit Neutral- respond to negative	Inhibit negative- respond to neutral	Inhibit Neutral- respond to negative
RT [mean (SD), in ms]	1029 (187)	890 (152)	967 (167)	774 (114)
Accuracy [mean (SD), % correct]	68 (15)	71 (16)	79 (13)	83 (16)
False alarm errors [mean (SD), No. of errors]	7 (6)	7 (4)	5 (4)	5 (5)
Omissions [mean (SD), No. of errors]	6 (4)	5 (5)	4 (2)	2 (3)

Note: Reaction times refer to correct responses only. Accuracy reflects both responses to targets and withheld responses to distracters. False alarm errors indicate responses to distracters. Omissions indicate withheld responses to targets.
