Effect of emotional arousal on inter-temporal decision-making: an fMRI study.

Sohn JH, Kim HE, Sohn S, Seok JW, Choi D, Watanuki S - J Physiol Anthropol (2015)

Bottom Line: Previous research has shown that emotion can significantly impact decision-making in humans.The current study examined whether or not and how situationally induced emotion influences people to make inter-temporal choices.These results suggest that 'stabilization of high emotional arousal' may facilitate a reduction of impulsive decision-making and implementation of longer term goals.

ABSTRACT

Background: Previous research has shown that emotion can significantly impact decision-making in humans. The current study examined whether or not and how situationally induced emotion influences people to make inter-temporal choices.

Methods: Affective pictures were used as experiment stimuli to provoke emotion, immediately followed by subjects' performance of a delay-discounting task to measure impulsivity during functional magnetic resonance imaging.

Results: Results demonstrate a subsequent process of increased impulsive decision-making following a prior exposure to both high positive and negative arousal stimuli, compared to the experiment subjects' experiences with neutral stimuli. Findings indicate that increased impulsive decision-making behaviors can occur with high arousal and can be characterized by decreased activities in the cognitive control regions such as prefronto-parietal regions.

Conclusions: These results suggest that 'stabilization of high emotional arousal' may facilitate a reduction of impulsive decision-making and implementation of longer term goals.

Fig1: Task design: participants performed delay-discounting task after affective picture presentation.

Mentions: During the fMRI run, subjects completed delay-discounting tasks via a computerized system (see FigureĀ 1). Subjects were repeatedly presented with two optional choices with a numeric variance between a smaller but sooner reward and a larger yet delayed reward by pressing a corresponding button on a response box [19].Figure 1
