Age Differences in the Influence of Induced Negative Emotion on Decision-Making: The Role of Emotion Regulation.

Objectives: In this study, we hypothesized that there is an age difference in the influence of negative emotion on decision-making and that this age difference is related to emotion regulation strategies.

Method: We carried out two studies. In the first, the older and younger adults completed the ultimatum game (UG) while in either an induced negative emotional or a neutral context. In the second, both the older and younger adults completed the UG while in an induced negative emotion while using either emotion reappraisal or expressive suppression to regulate their emotions during the task.

Results: The first study showed that, unlike younger adults, the older adults made similar choices in the neutral and negative induction groups. In addition, the older adults predominantly used a reappraisal strategy in both the negative and neutral emotional states, whereas the younger adults predominantly used a suppression strategy in the negative emotional state. In the second study, after the emotion regulation strategies were experimentally manipulated so that both age groups used the same strategy, we found no age difference in decision-making.

Discussion: Our findings indicated that the influence of negative emotion on decision-making differs between older and younger adults and that this age difference was associated with their different emotion regulation processes.
