How do people cope with setbacks and persist with their goals? We examine how perceiving control over setbacks alters neural processing in ways that increase persistence through adversity. For example, a student might retake a class if initial failure was due to controllable factors (e.g., studying) but give up if failure was uncontrollable (e.g., unfair exam questions). Participants persisted more when they perceived control over setbacks, and when they experienced increased negative affect to setbacks. Consistent with previous observations involving negative outcomes, ventral striatum and ventromedial prefrontal (VMPFC) activity was decreased in response to setbacks. Critically, these structures represented distinct neural mechanisms for persistence through adversity. Ventral striatum signal change to controllable setbacks correlated with greater persistence, whereas VMPFC signal change to uncontrollable setbacks mediated the relationship between increased negative affect and persistence. Taken together, the findings highlight how people process setbacks and adapt their behavior for future goal pursuit.
人们如何应对挫折并坚持自己的目标?我们研究了对挫折的可控感如何改变神经处理方式,从而在逆境中增强坚持性。例如,如果最初的失败是由于可控因素(如学习),学生可能会重修课程,但如果失败是不可控的(如不公平的考试题目),则会放弃。当参与者认为对挫折有可控感时,以及当他们对挫折产生更多负面情绪时,他们会更坚持。与之前涉及负面结果的观察一致,腹侧纹状体和腹内侧前额叶(VMPFC)对挫折的反应活动减少。关键的是,这些结构代表了在逆境中坚持的不同神经机制。腹侧纹状体对可控挫折的信号变化与更强的坚持性相关,而VMPFC对不可控挫折的信号变化介导了负面情绪增加与坚持性之间的关系。综上所述,这些发现突出了人们如何处理挫折并调整行为以追求未来目标。
