The coping heart: Vagal reactivity moderates the relation between cognitive reappraisal and advantageous decision-making

Résumé

Background: The decision we make can have major and lasting consequences in the long term. Growing evidence shows that making decisions resulting in favorable outcomes require efficient emotion regulation strategies. Interestingly, the autonomic nervous activity has been shown to play a central role in decision-making according to the somatic marker theory, but also in emotional processing according to the neurovisceral integration model. Here, we test whether efficient vagal changes (heart rate variability) during the task modulate the interplay between emotion regulation strategies. Methods: Young adults (n=54), completed the Iowa Gambling Task (i.e. test that simulates real-life decision making) while wearing an electrocardiogram monitor. Then, they answered the Emotion Regulation Questionnaire (assessing cognitive reappraisal). Vagal activity in resting state and during the task were recording and subtracted to compute vagal reactivity. Several potential confounders (alcohol intake, smoking, body mass index, depression, anxiety, medication…) were controlled. Results: Vagal reactivity modulates the association between cognitive reappraisal and advantageous decision-making (F(3, 49) = 6.22, p < .001, R2 = .23). Cognitive reappraisal positively predicts advantageous decision-making, but only when vagal reactivity during the task is high (β = 1.03, p < .01) or moderate (β = 1.03, p = .02) and not when it is low (p > .10). Discussion: Our results support the role of heart-brain interactions in decision making. In addition to therapeutic exercises on emotion regulation, lifestyle interventions, such as simple breathing exercises that enhance vagus nerve activity, may further benefit patients with difficulties in making self-beneficial choices (e.g., alcoholism).
