Surpassing negative evaluation is a recurrent theme of success stories. Yet, there is little evidence supporting the counterintuitive idea that negative evaluation might not only motivate people, but also enhance performance. To address this question, we designed a task that required participants to decide whether taking up a risky challenge after receiving positive or negative evaluations from independent judges. Participants believed that these evaluations were based on their prior performance on a related task. Results showed that negative evaluation caused a facilitation in performance. Concurrent functional magnetic resonance imaging revealed that the motivating effect of negative evaluation was represented in the insula and striatum, while the performance boost was associated with functional positive connectivity between the insula and a set of brain regions involved in goal-directed behavior and the orienting of attention. These findings provide new insight into the neural representation of negative evaluation-induced facilitation.
超越负面评价是成功故事的一个反复出现的主题。然而,几乎没有证据支持这样一种反直觉的观点,即负面评价不仅能激励人们,而且能提高表现。为了解决这个问题,我们设计了一项任务,要求参与者在收到独立评委的正面或负面评价后,决定是否接受一项有风险的挑战。参与者认为这些评价是基于他们之前在相关任务上的表现。结果表明,负面评价会促进表现。同时进行的功能性磁共振成像显示,负面评价的激励效应表现在脑岛和纹状体中,而表现的提升则与脑岛和一组参与目标导向行为和注意力定向的大脑区域之间的功能正连接有关。这些发现为负面评价引起的促进作用的神经表现提供了新的见解。
