Table 2.

Reaction time data (Mean, SD) from the dot probe task across the four medication conditions

	N	Angry Face and Probe on Different Side (Incongruent)	Angry Face and Probe on Same Side (Congruent)
Yohimbine	8	450.55 (119.80)	446.84 (115.06)
Hydrocortisone	7	546.80 (123.28)	524.58 (126.45)
Yohimbine/Hydrocortisone	8	460.37 (178.67)	451.68 (180.74)
Placebo	8	510.25 (59.64)	464.16 (48.72)

Mean threat bias score was calculated by subtracting the mean reaction time for congruent trials from the mean reaction time for incongruent trials. Placebo had a significantly higher mean threat bias compared to yohimbine (p = .001, d = 2.18) as well as Y+H (p < .01, d = 1.70).
