睡眠剥夺会改变注意力功能，如警惕或紧张性警觉（即，在一段时间内维持警报状态）。然而，睡眠不足对定向和执行控制的影响仍然不清楚，也没有研究评估睡眠不足是否会影响这三个注意系统之间的关系。为了考察警觉、定向和执行控制这三种注意网络在单一任务中的效率，我们使用了注意网络测验（ANT）。18名惯用右手的男性参与者参加了连续两天的实验。在第一天，每个参与者进行20分钟的ANT训练。在第二天，参与者保持清醒24小时，在此期间，ANT在下午5：00和凌晨4：00进行一次。结果显示，在夜间会议的反应时间整体放缓，表明警惕性大幅下降。此外，睡眠剥夺确实影响注意定向和执行控制。结果是一致的假设，紧张成分的警觉相互作用的注意定向和执行功能。
Sleep deprivation alters attentional functions like vigilance or tonic alerting (i.e., sustaining an alert state over a period of time). However, the effects of sleep loss on both orienting and executive control are still not clear, and no study has assessed whether sleep deprivation might affect the relationships among these three attentional systems. In order to investigate the efficiency of the three attentional networks-alerting, orienting and executive control-within a single task, we used the Attention Network Test (ANT). Eighteen right-handed male participants took part in the experiment, which took place on two consecutive days. On the first day, each participant performed a 20 min training session of the ANT. On the second day, participants remained awake for 24 h during which time the ANT was performed once at 5:00 p.m. and once at 4:00 a.m. Results showed an overall slowing of reaction times in the nocturnal session, indicating a strong decrease in vigilance. Furthermore, sleep deprivation did affect attentional orienting and executive control. Results are consistent with the hypothesis that the tonic component of alerting interacts with both attentional orienting and executive functions.
