大量的研究致力于了解短期（<48小时）完全睡眠剥夺（SD）对各种认知领域结果的影响。尽管有如此丰富的信息，但在如何解释这些数据方面存在分歧，部分原因是这些领域的效应量的相对大小尚不清楚。为了解决这个问题，我们进行了一项荟萃分析，以发现短期SD对6个认知类别的速度和准确性测量的影响：简单注意力，复杂注意力，工作记忆，处理速度，短期记忆和推理。70篇文章包含147项认知测试，符合本研究的纳入标准。效应大小从小到不显著（推理准确度：r =-0.125，95%CI [-0.27，0.02]）到大（简单注意力的丧失：r =-0.776，95%CI [-0.96，-0.60]，p <0.001）不等。在认知领域，速度和准确性都有显着差异，但是，在每个认知领域内的速度和准确性指标之间没有差异。在测试的几个主持人中，只有清醒时间是研究间变异性的重要预测因子，并且仅用于准确性测量，这表明测试特征的异质性可能占剩余研究间方差的显著部分。这些研究结果的理论意义SD和认知的研究进行了讨论。
A substantial amount of research has been conducted in an effort to understand the impact of short-term (<48 hr) total sleep deprivation (SD) on outcomes in various cognitive domains. Despite this wealth of information, there has been disagreement on how these data should be interpreted, arising in part because the relative magnitude of effect sizes in these domains is not known. To address this question, we conducted a meta-analysis to discover the effects of short-term SD on both speed and accuracy measures in 6 cognitive categories: simple attention, complex attention, working memory, processing speed, short-term memory, and reasoning. Seventy articles containing 147 cognitive tests were found that met inclusion criteria for this study. Effect sizes ranged from small and nonsignificant (reasoning accuracy: ḡ = −0.125, 95% CI [−0.27, 0.02]) to large (lapses in simple attention: ḡ = −0.776, 95% CI [−0.96, −0.60], p < .001). Across cognitive domains, significant differences were observed for both speed and accuracy; however, there were no differences between speed and accuracy measures within each cognitive domain. Of several moderators tested, only time awake was a significant predictor of between-studies variability, and only for accuracy measures, suggesting that heterogeneity in test characteristics may account for a significant amount of the remaining between-studies variance. The theoretical implications of these findings for the study of SD and cognition are discussed.
