Being able to adequately process numbers is a key competency in everyday life. Yet, self-reported negative affective responses towards numbers are known to deteriorate numerical performance. Here, we investigated how physiological threat responses predict numerical performance. Physiological responses reflect whether individuals evaluate a task as exceeding or matching their resources and in turn experience either threat or challenge, which influences subsequent performance. We hypothesized that, the more individuals respond to a numerical task with physiological threat, the worse they would perform. Results of an experiment with cardiovascular indicators of threat/challenge corroborated this expectation. The findings thereby contribute to our understanding of the physiological mechanism underlying the influence of negative affective responses towards numbers on numerical performance.
能够充分处理数字是日常生活中的一项关键能力。然而，众所周知，自我报告的对数字的负面情绪反应会降低数字处理表现。在此，我们研究了生理威胁反应如何预测数字处理表现。生理反应反映了个体是否认为一项任务超出或匹配了他们的能力，进而体验到威胁或挑战，这会影响后续表现。我们假设，个体对数字任务产生的生理威胁反应越多，他们的表现就会越差。一项使用威胁/挑战的心血管指标的实验结果证实了这一预期。这些发现有助于我们理解对数字的负面情绪反应影响数字处理表现的生理机制。
