睡眠剥夺后记忆的分离和元记忆研究

Memory Dissociation and Metamemory After Sleep Deprivation

本研究使用词干补笔作业,探讨不同条件下(SD21、SD45、SD69、对照组)记忆作业中有意识成分、无意识成分以及元记忆的情况。结果表明:SD后,意识性提取和自动提取的贡献概率均下降,69h后下降显著,且自动提取下降速率快于意识性提取;SD后包含条件下的前瞻性元记忆判断、包含和排除条件下的回溯性元记忆判断同成绩的相关系数有显著意义;相对回溯性元记忆,前瞻性元记忆受SD影响更为严重,并且回溯性元记忆判断可能由于自身的反馈调节,受SD影响并不严重。

With the word-stem task, the conscious contribution rate, automatic contribution rate and metamemory were studied in different sleep deprivation conditions （SD21, SD45, SD69, control）. The results showed that conscious and automatic contribution rates declined after sleep deprivation significantly after SD69. The decline of automatic contribution rates was faster than that of conscious ones. After SD, JOL in the inclusion condition and JOC in both inclusion and exclusion conditions were significantly correlated with answers. Compared with JOC, JOL was more damaged by SD while JOC was little affected because of the selfregulation mechanism.
