Previous research has revealed that incidental emotions of different valence (positive/negative/neutral) produce distinct impacts on risk decision-making. This study went on to compare the effects of different emotions of which the valence are identical. We focused on anger and fear, both of which are negative emotions but differ in motivational and appraisal dimensions. Participants finished a forced-choice gambling task, during which incidental emotions (anger/fear/happy) were elicited by facial stimuli selected from the Chinese Facial Affective Picture System. Behavioral and event-related potential (ERP) data were recorded in the experiment, which showed that anger and fear were different in their influence on behavioral risk preference and the relationship between outcome processing and subsequent risk decisions. Regarding the behavioral results, risk preference in the anger condition was higher than the fear condition, but lower than the happy condition. Regarding the ERP results elicited by outcome feedback (gain/loss), in the fear condition, the feedback-related negativity (FRN) was positively correlated with risk preference; in the anger condition, the gain-related P3 component was positively correlated with risk preference; in the happy condition, both the FRN and the loss-related P3 was negatively correlated with risk preference. The current findings provide novel insight into distinguishing the effect of different incidental emotions on risk preference.
