Regulating emotions in two languages: How do emotion regulation strategies relate to physiological reactivity in emotional contexts?

Aims and Objectives/Purpose/Research Questions: Differences in how people regulate their emotions have been shown across cultures. Yet, whether bilinguals regulate emotions differently based on the language they are speaking is unknown, as is whether these regulatory choices relate to their physiology. The aim of this study was to assess whether self-reported use of emotion regulation strategies that promote emotional engagement would be associated with greater sympathetic arousal while describing emotional experiences for bilinguals. Design/Methodology/Approach: 99 Spanish–English bilinguals (M = 20.8 years; SD = 2.11; 73 women) were interviewed about times they felt sad and afraid in both Spanish and English, and described what they did to regulate those emotions. Sympathetic nervous system physiology (pre-ejection period; PEP) was assessed continuously. The within-person experimental design enabled exploration of differences in regulation and physiology that were associated with talking about negative emotions in different languages. Data and Analysis: Emotion regulation strategies that indexed emotional engagement (e.g. cognitive reappraisal) were reliably coded from participant interviews. PEP reactivity was calculated as the change from a resting baseline to each language context. We used hierarchical linear regressions to test our hypotheses. Findings/Conclusions: We found that using fewer engagement strategies was associated with decreased sympathetic arousal, but only for people who were more physiologically aroused when at rest and only when participants were speaking English. Originality: This study is the first to show that bilinguals’ emotion regulatory attempts have different consequences across languages, highlighting how emotional processing is colored by cultural-linguistic lenses. Significance/Implications: These findings align with growing evidence that bilinguals’ physiological reactions to emotional events depend on the language context. Knowledge generated by this investigation contributes to our understanding of cross-cultural differences in people’s physiological arousal and emotional processing by highlighting these patterns among the understudied population of bilingual speakers.
