marginally significantp = .054
The test on RTs became marginally significant if we used a two-tailed t test ( p = .054), but we felt that a one-tailed test was more appropriate because of our clear prediction.

However, subjects performed worse on the number task in Experiment 4 (average d' = 1.71) than in Experiment 1 (average d' = 2.8) [ t (26) = 2.48, p = .02], and their RTs were higher in Experiment 4 (mean RT = 1.08 s) than in Experiment 1 (mean RT = 0.84 s), with this difference approaching significance [ t (26) = 1.91, p = .07].
