焦虑的忧虑/担忧与夸大的错误监控有关；然而，这种关系背后的确切机制仍不清楚。当前的研究通过检查担忧与错误监控之间的关系（以错误相关负性（ERN）为索引，作为错误之手（实验 1）和刺激取向（实验 2）的函数），检验了担忧-错误监控关系涉及左脑语言活动的假设。结果显示，这种担忧完全与 ERN 对语言主导的左半球所犯的右手错误有关。此外，只有当刺激水平呈现（已知会激活言语过程）而不是垂直呈现时，右手ERN-担忧关系才会出现。总之，这些发现表明，担忧与 ERN 的关系涉及左半球的言语处理，阐明了解释焦虑中错误监测异常的潜在机制。讨论了理论和实践的意义。
Anxious apprehension/worry is associated with exaggerated error monitoring; however, the precise mechanisms underlying this relationship remain unclear. The current study tested the hypothesis that the worry-error monitoring relationship involves left-lateralized linguistic brain activity by examining the relationship between worry and error monitoring, indexed by the error-related negativity (ERN), as a function of hand of error (Experiment 1) and stimulus orientation (Experiment 2). Results revealed that worry was exclusively related to the ERN on right-handed errors committed by the linguistically dominant left hemisphere. Moreover, the right-hand ERN-worry relationship emerged only when stimuli were presented horizontally (known to activate verbal processes) but not vertically. Together, these findings suggest that the worry-ERN relationship involves left hemisphere verbal processing, elucidating a potential mechanism to explain error monitoring abnormalities in anxiety. Implications for theory and practice are discussed.
