BackgroundOutcome feedback which indicates behavioral consequences are crucial for reinforcement learning and environmental adaptation. Nevertheless, outcome information in daily life is often totally or partially ambiguous. Studying how people interpret this kind of information would provide important knowledge about the human evaluative system.MethodsThis study concentrates on the neural processing of partially ambiguous feedback, that is, either its valence or magnitude is unknown to participants. To address this topic, we sequentially presented valence and magnitude information; electroencephalography (EEG) response to each kind of presentation was recorded and analyzed. The event‐related potential components feedback‐related negativity (FRN) and P3 were used as indices of neural activity.ResultsConsistent with previous literature, the FRN elicited by ambiguous valence was not significantly different from that elicited by negative valence. On the other hand, the FRN elicited by ambiguous magnitude was larger than both the large and small magnitude, indicating the motivation to seek unambiguous magnitude information. The P3 elicited by ambiguous valence and ambiguous magnitude was not significantly different from that elicited by negative valence and small magnitude, respectively, indicating the emotional significance of feedback ambiguity. Finally, the aforementioned effects also manifested in the stage of information integration.ConclusionThese findings indicate both similarities and discrepancies between the processing of valence ambiguity and that of magnitude ambiguity, which may help understand the mechanisms of ambiguous information processing.

Motivation underlies much perception, cognition, and behavior. As such, it is studied from many levels of analysis within psychology and neuroscience. In this chapter, we review research and theory on the psychology of motivation from the perspective of social emotive neuroscience, which is an integrative approach involving social/personality psychology, psychophysiology, affective neuroscience, and the study of emotions and motivation within humans. More specifically, this chapter reviews theory and research on two major dimensions of motivation: motivational intensity and motivational direction (approach/withdrawal). In particular, theory and research are reviewed that demonstrate how motivational intensity and direction are related to psychophysiological and cognitive responses. The reviewed research also considers individual differences and bodily expressions/postures. Moreover, theory and research are reviewed that suggest that cognitive dissonance processes may be aimed at resolving motivational conflicts. This review illustrates the benefits of the integrative approach of social emotive neuroscience.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
