Besides degrading vigilant attention, total sleep deprivation (TSD) impairs reversal learning performance and blunts affective reactions to feedback. Whether these effects are downstream consequences of information acquisition failures from degraded vigilant attention, or distinct from degraded vigilant attention, is unclear. In well-rested individuals we simulated information acquisition failures by masking a portion of trial information in a go/no-go reversal learning task with four conditions: stimulus masking, feedback masking, alternating stimulus/feedback masking, and no-masking control. No condition reproduced the previously documented pattern of TSD effects, suggesting that information acquisition failures cannot fully account for impaired reversal learning and blunted affective reactions during TSD.
除了降低警觉注意力，完全睡眠剥夺（TSD）还会损害反转学习表现，并削弱对反馈的情绪反应。这些影响是源自警觉注意力下降导致的信息获取失败的下游后果，还是与警觉注意力下降不同，目前尚不清楚。在休息良好的个体中，我们在一个 Go/No-Go 反转学习任务中使用四种条件模拟了信息获取失败：刺激掩蔽、反馈掩蔽、刺激/反馈交替掩蔽和无掩蔽对照。没有一种条件再现了 TSD 效应的先前记录模式，这表明信息获取失败不能完全解释 TSD 期间反转学习受损和情绪反应减弱的原因。
