Role of the valuation of nervousness in cortisol responses to psychosocial stress task and task performance in European American and East Asian students
How people perceive and value negative affective states is associated with physiological responses to stressful events and moderates the association between negative feelings and physiological and behavioral outcomes. However, previous studies on valuation of negative affective states have been conducted mostly in Western cultures. Different cultural backgrounds shape how people view negative emotions as well as how people attend to internal emotional states, which may change the effects of valuing negative emotions. The present study thus examined whether valuation of nervousness was associated with the magnitude and duration of cortisol responses to a standardized laboratory stressor and task performance in East Asian and European American students. Two hundred undergraduate students were recruited through a large pool of students taking psychology courses. They engaged in demanding speech and arithmetic tasks as part of the Trier Social Stress Test (TSST). European American participants who had a higher valuation of nervousness showed lower cortisol reactivity. Valuing nervousness was associated with better speech performance in students from both cultural backgrounds, and the strength of this association was moderated by cortisol level. Our findings call attention to the importance of considering whether negative emotions are viewed as beneficial or an impediment, as well as the cultural context when responding to demanding and threatening situations.
•European American participants who had a higher valuation of nervousness showed a lower cortisol reactivity.•Individual variation in the valuation of nervousness did not significantly moderate the duration of responses among East Asian students.•Valuing nervousness was related to better speech performance.•The association was moderated by the cortisol increment from baseline to post-task.•The study highlights a potential benefit of valuing nervousness during a demanding task.•Need to consider both how negative emotions are viewed and cultural contexts when responding to demanding situations.
