(A and C) Experiment I revealed a main effect of reward over right frontal sensors 200–500 ms after stimulus onset (A) and a later main effect of novelty over parietal/occipital sensors 500–700 ms after stimulus onset (C).
(B and D) In the absence of reward (experiment II), novelty effects were observed over frontal regions 200–500 ms (B) and 500–700 ms (D) after stimulus onset.
