Is emotion regulation impacted by executive functions? An experimental study

The ability to exert influence on our emotions plays a significant role in the attainment of our goals. To have control over when and how we experience emotions is thought to be impacted by higher cognitive processes such as executive functions. However, there is inadequate research to support this notion. Hence, we examined the relationship between executive functions - updating, shifting, and inhibition - and emotion regulation strategies - cognitive reappraisal and expressive suppression. We predicted that updating would positively relate to cognitive reappraisal, while inhibition would positively relate to expressive suppression. Shifting would positively relate to both cognitive reappraisal and expressive suppression. Participants completed updating, shifting, and inhibition tasks. Then, they used expressive suppression or cognitive reappraisal strategies in response to unpleasant pictures, accompanied by a physiological recording. Faster updating was associated with a larger heart rate deceleration during reappraisal. Inhibition was associated with more frequent use of suppression. Overall, the results confirm the idea that a higher level of executive functions is partially related to the effective application of emotion regulation strategies. The content of executive function tasks does not affect the association between executive functions and emotion regulation. These findings are important for psychotherapy, as training executive functions could partially help in the treatment of mood-related disorders.
