DESCRIPTION (Adapted from Investigator's Abstract): The proposed five series of studies have the long-term aim of characterizing age-related differences and similarities in the implicit learning of structural regularities in the environment. By using an alternating serial (visual- spatial) motor response task, where pattern trials alternate with random trials, the investigators will test the hypotheses that when comparing performance of young (18-25 years) and old (65 years and older) the following will occur: (1) age-related deficits will appear in implicit sequence learning, including decreases in the rate and magnitude of learning, in the level of structure that is learned, in the extent to which this knowledge can be used in the absence of stimuli, and in the extent to which it is verbalizable (declarative knowledge); (2) the Alternating Serial Response Time Task will result in unintentional learning, at least partially outside of awareness; (3) the age-related deficits in implicit serial pattern learning will be due in part to age- related decreases in processing deficits, such as slowing and the number of items that can be held simultaneously in working memory and that these age deficits can be simulated in a connectionist modeling network by manipulating the number of events used as input.

描述（改编自研究者摘要）：拟议的五个 一系列研究的长期目标是描述年龄相关的 内隐学习的异同 在环境中。通过使用交替序列（视觉- 空间）运动反应任务，其中模式试验与随机试验交替进行 试验，研究人员将测试的假设，当比较 年轻人（18-25岁）和老年人（65岁及以上）的业绩 （1）年龄相关的缺陷将出现在内隐 序列学习，包括减少的速度和幅度， 学习，在学习的结构水平，在程度上， 这种知识可以在没有刺激的情况下使用， （2）知识的范围;（3）知识的范围。 交替串行响应时间任务将导致意外 学习，至少部分是在意识之外;（3）年龄相关的 内隐序列模式学习的缺陷将部分归因于年龄- 相关的减少处理赤字，如减缓和数量 这些项目可以同时保存在工作记忆中， 这些年龄缺陷可以在联结主义建模网络中模拟， 通过操纵用作输入的事件的数量。
