Independence of Valence and Reward in Emotional Word Processing: Electrophysiological Evidence

Laura Kaltwasser, Stephanie Ries, Werner Sommer, Robert T. Knight & Roel M. Willems
Both emotion and reward are primary modulators of cognition: emotional word content enhances word processing, and reward expectancy similarly amplifies cognitive processing from the perceptual up to the executive control level. Here, we investigate how these primary regulators of cognition interact. We studied how the anticipation of gain or loss modulates the neural time course (event-related potentials, ERPs) related to processing of emotional words. Participants performed a semantic categorization task on emotional and neutral words,...
