Abstract

Sleep deprivation (SD) is known to impair cognitive performance, yet its effects on higher-order cognitive control remain poorly understood. This study investigated the impact of 36-hour SD on proactive and reactive control using the AX-Continuous Performance Task (AX-CPT) and event-related potentials (ERP). Thirty-three healthy college students underwent 36 h of continuous SD, with cognitive performance assessed at baseline, following 24 and 36 h of SD. Behavioral results revealed significant impairments in proactive and reactive control, as indicated by increased error rates and longer response times in BX and AY trials, respectively. However, proactive control remained the dominant strategy throughout the SD period, as evidenced by positive Proactive Behavioral Index (PBI) values, smaller P3 and larger CNV amplitudes for cue A, and larger N2 and smaller P3 amplitudes for AY trials. These results provide novel insights into the cognitive mechanisms underlying SD-induced impairments and highlight the robustness of proactive control in sleep-deprived individuals. The findings have practical implications for developing interventions to enhance cognitive performance in high-stakes tasks that require flexible control under SD.

睡眠剥夺对认知控制的影响：来自控制理论双重机制的见解。

众所周知，睡眠剥夺会损害认知能力，但其对高阶认知控制的影响尚不清楚。本研究利用ax -连续表现任务（AX-CPT）和事件相关电位（ERP）研究了36小时SD对主动和被动控制的影响。33名健康的大学生接受了连续36小时的SD治疗，在24小时和36小时的SD治疗后，以基线水平评估认知表现。行为学结果显示，在BX和AY试验中，主动式和反应性控制方面存在显著损伤，分别表现为错误率增加和反应时间延长。然而，在整个SD期间，主动控制仍然是主导策略，这一点可以从积极的主动行为指数（PBI）值中得到证明，提示A的P3值更小，CNV值更大，而提示A的N2值更大，P3值更小。这些结果为sd诱发损伤的认知机制提供了新的见解，并强调了睡眠剥夺个体主动控制的稳健性。研究结果对开发干预措施以提高在高风险任务中需要灵活控制的认知表现具有实际意义。

期刊介绍： Biological Psychology publishes original scientific papers on the biological aspects of psychological states and processes. Biological aspects include electrophysiology and biochemical assessments during psychological experiments as well as biologically induced changes in psychological function. Psychological investigations based on biological theories are also of interest. All aspects of psychological functioning, including psychopathology, are germane. The Journal concentrates on work with human subjects, but may consider work with animal subjects if conceptually related to issues in human biological psychology.
