↵a To examine time course effects, we also applied a four (run: 1, 2, 3, 4) by three (decision form: PunPun, RewRew, RewPun) by three (distance: close, medium, far) ANOVA to the RT data. There was a main effect of run (F(1.74,33.11) = 5.84; p < 0.01); performance did improve across runs, however, there was no significant run by decision form, run by distance, or run by decision form by distance interactions (F = 2.51, 1.41, and 0.84, respectively). That is, although there was a general improvement in performance, it did not differentially impact on the three different decision forms or distances.
