Dissociable influences of reward motivation and positive emotion on cognitive control.

Of the correlations examining the relationship between proactive indices and pupil dilation in the cue maintenance period, we observed significant positive correlations between the Baseline–Rew RT proactive index and Baseline–Rew B-cue pupil dilation [ r (98) = .208, p = .04] and between the Rew–Neut error proactive index and Rew–Neut B-cue pupil dilation [ r (99) = .227, p = .024], as well as a positive trend-level correlation between the Rew–Rew minus Rew–Neut error proactive index and Rew–Rew minus Rew–Neut B-cue pupil dilation [ r (99) = .174, p = .085].
