Despite the increasing insights into the significant impact of sleep on memory consolidation it is still unclear whether memory consolidation in adolescents is modulated by the length of the time interval between the acquisition of new knowledge or skills and sleep. The proposed research project will test the hypothesis that sleep directly after learning significantly facilitates procedural and declarative memory consolidation compared to sleep after an interim waking period with limited sensory input between learning and bedtime.This is a randomised, comparison study in a parallel group design. 52 healthy post-pubertal adolescents (16-17 years, 26 females, 26 males, matched for age and gender, and stratified for IQ, motivation and morningness/ eveningness types) will be allocated to two conditions with polysomnographic monitoring: group 1 (n = 26) will complete a test battery with verbal and visual declarative tasks and a procedural skill in the afternoon, spend the remaining afternoon with standardised, supervised activities, watch a movie afterwards and go to bed; group 2 (n = 26) will watch the movie in the afternoon and complete the same test battery in the evening, immediately before going to sleep. Both groups will be retested on the following morning.Results from this research project are expected to increase our knowledge on the impact of sleep on memory formation in adolescents with the ultimate goal being a translation of this informa-tion into learning strategies for adolescents.

尽管越来越多的人认识到睡眠对记忆巩固的重要影响，但仍不清楚青少年的记忆巩固是否受到获得新知识或技能与睡眠之间的时间间隔的调节。拟议的研究项目将测试这样一个假设，即与在学习和就寝之间有限的感觉输入的过渡清醒期后睡眠相比，学习后直接睡眠显著促进程序记忆和陈述性记忆的巩固。这是一项平行组设计的随机对照研究。52名健康的青春期后青少年（16-17岁，26名女性，26名男性，年龄和性别匹配，根据智商、动机和早起/晚睡类型进行分层）将被分配到两种条件下进行多导睡眠监测：1组（n = 26）将在下午完成一系列口头和视觉陈述性任务和程序技能测试，剩下的下午将进行标准化的、有监督的活动，之后看电影，然后睡觉；第二组（n = 26）将在下午看电影，并在晚上睡觉前完成相同的测试电池。两组将在第二天早上重新测试。这项研究项目的结果有望增加我们对睡眠对青少年记忆形成影响的认识，最终目标是将这些信息转化为青少年的学习策略。
