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.

Neuroimaging results: brain regions activated in delay discounting task. (A) Neutral minus negative emotional condition. (B) Neutral minus positive emotional condition. (C, D, E) Shown are the mean activations of the orbitofrontal gyrus (OFG), inferior parietal gyrus (IPG), and dorsalateral prefrontal cortex (DLPFC) expressed as percent signal change. In these regions, activation was greatest in the neutral condition. Neu neutral, Neg negative, Pos positive.

Fig2: Neuroimaging results: brain regions activated in delay discounting task. (A) Neutral minus negative emotional condition. (B) Neutral minus positive emotional condition. (C, D, E) Shown are the mean activations of the orbitofrontal gyrus (OFG), inferior parietal gyrus (IPG), and dorsalateral prefrontal cortex (DLPFC) expressed as percent signal change. In these regions, activation was greatest in the neutral condition. Neu neutral, Neg negative, Pos positive.

Mentions: Analysis on the BOLD response for the delay discounting following emotional manipulation was conducted by calculating the following four contrasts: neutral minus negative (neu > neg), neutral minus positive (neu > pos), negative minus neutral (neg > neu), and positive minus neutrals (pos > neu). The ROIs within group analysis are illustrated in Table 2 and Figure 2, with their x-, y-, and z-coordinates and cluster sizes.Table 2
