The Condition main effect was significant for Latency: F(1, 85) = 16.89, p < .001, ηp2 = .17, 1-β = .98. A pairwise comparison indicated that the non-reward condition had a shorter latency than the reward condition, mean difference = −13.29 msec, SE = 3.15. A main effect of Sex for latency was observed, F(1, 85) = 4.67, p = .03, ηp2= .05, 1-β = .57. This was qualified by a significant Condition × Sex interaction, F(1, 85) = 4.05, p = .047, ηp2 = .05, 1-β = .51. Post hoc tests (independent t-tests of the sex effect in each condition) indicated that in the non-reward condition there was no sex difference, t(89) = .64, p = .53. However in the reward condition, males had a significantly longer latency than females, t(89) = 2.40, p = .02, mean difference = 15.87, SE = 6.61.
