ABSTRACT

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.

摘要

除了降低警惕性注意力之外，完全睡眠剥夺 (TSD) 还会损害逆转学习表现并削弱对反馈的情感反​​应。这些影响是由于警惕注意力下降导致信息获取失败的下游后果，还是与警惕注意力下降不同，尚不清楚。在休息良好的个体中，我们通过在 go/no-go 反转学习任务中屏蔽一部分试验信息来模拟信息获取失败，其中包括四种条件：刺激屏蔽、反馈屏蔽、交替刺激/反馈屏蔽和无屏蔽控制。没有条件重现先前记录的 TSD 效应模式，这表明信息获取失败不能完全解释 TSD 期间逆向学习受损和情感反应迟钝。
