The Influence of Emotion Regulation on Arousal and Performance in Math Anxiety
Interventions targeting anxious emotion may be efficacious in reducing the negative impact of stress on mathematics performance. However, different regulation strategies may have different effects on arousal, which in turn may have different effects on task performance. In the present study, we recorded skin conductance levels in order to examine the effect of arousal on performance during different applied emotion regulation strategies. In particular, we were interested in how these emotion regulation strategies might affect the negative performance deficits attributed to anxious arousal in math anxious individuals. Participants were instructed to use cognitive reappraisal (distancing oneself from the stressful math task by thinking objectively about the problem in a low-stakes scenario), expressive suppression (maintaining a neutral emotional expression), or their own problem-solving technique (control). We recorded electrodermal activity (EDA), measuring skin conductance responses during each trial. Results indicate that HMA individuals show worse performance on the math task as well as increased sympathetic arousal (EDA) during the unregulated control condition for math. Notably, this arousal was reduced by reappraisal but exacerbated by suppression. Further, for both HMA and LMA groups, reappraisal reduced the impact of arousal on task accuracy, indicating that even elevated arousal levels no longer had a negative impact on math performance. Overall, these results show that reappraisal provides a promising technique for ameliorating the negative influence of math anxiety on math performance.
