先前的行为和电生理学证据表明，一晚完全睡眠剥夺（TSD）会损害错误监测，包括错误检测、错误纠正和错误后调整（PEA）。本研究检验了这样的假设：纠错（表现为对错误的公开表达的自我生成的性能反馈）可以有效防止 TSD 引起的 PEA 损伤。十六名年龄在 19 至 23 岁之间的健康右手成年人（七名女性和九名男性）被指示对两侧有四支分散箭头的目标箭头做出反应，并在犯错后立即纠正错误。采用平衡重复测量设计，在正常睡眠 (NS) 后和一晚 TSD 后收集任务表现和脑电图 (EEG) 数据。由于纠错的需求，参与者在 TSD 后在减少试验 N + 1 的错误率方面保持与 NS 后相同的 PEAs 水平。纠正行为进一步影响了试验 N+1 的 PEAs 的遗漏率和响应速度，在纠正错误后，特别是在 TSD 后，PEA 下降并加快。这些结果表明，纠错有效地保持了 TSD 后提交错误和遗漏错误的后错误减少。大脑机制可能与错误纠正的效果有关，因为与正确反应相比，错误反应后脑电图β（17-24 Hz）活动增加。对于从事单调但需要注意力的监控任务的工人来说，建议将纠错实际应用于提高工作安全性，因为重复的错误可能会危及安全性。
Previous behavioral and electrophysiologic evidence indicates that one night of total sleep deprivation (TSD) impairs error monitoring, including error detection, error correction, and posterror adjustments (PEAs). This study examined the hypothesis that error correction, manifesting as an overtly expressed self-generated performance feedback to errors, can effectively prevent TSD-induced impairment in the PEAs. Sixteen healthy right-handed adults (seven women and nine men) aged 19-23 years were instructed to respond to a target arrow flanked by four distracted arrows and to correct their errors immediately after committing errors. Task performance and electroencephalogram (EEG) data were collected after normal sleep (NS) and after one night of TSD in a counterbalanced repeated-measures design. With the demand of error correction, the participants maintained the same level of PEAs in reducing the error rate for trial N + 1 after TSD as after NS. Corrective behavior further affected the PEAs for trial N + 1 in the omission rate and response speed, which decreased and speeded up following corrected errors, particularly after TSD. These results show that error correction effectively maintains posterror reduction in both committed and omitted errors after TSD. A cerebral mechanism might be involved in the effect of error correction as EEG beta (17-24 Hz) activity was increased after erroneous responses compared to after correct responses. The practical application of error correction to increasing work safety, which can be jeopardized by repeated errors, is suggested for workers who are involved in monotonous but attention-demanding monitoring tasks.
