How are behavioral sequences learned and integrated? The proposed research will investigate non-verbal mechanisms underlying serially organized behavior by studying its cognitive development in monkeys. This strategy eliminates two factors that complicate the study of serially organized behavior in human subjects: language and experience with serial tasks. The investigation of serial learning animals also provides a comparative perspective of mechanisms of serially organized behavior. How behavioral sequences are learned and integrated will be studied with two recently developed techniques for training monkeys to produce and recall lists of arbitrary and numerical stimuli. In the simultaneous chaining paradigm, all of the stimuli and opportunities to respond are available simultaneously, a key feature of serial tasks used in verbal learning experiments on human subjects. Since their configuration is changed from trail to trial subjects must rely on a representation of their ordinal position while executing the required sequence. Short-term serial memory will be studied with a delayed-matching-to-successive-samples paradigm in which the subject is required to reproduce the list displayed as the sample as a simultaneous chain. Some lists will provide real-time measures of mechanisms underlying sequential behavior. Another unusual feature of the proposed research is the extensive experience of many of the subjects in performing serial tasks with arbitrary and numerical stimuli. The experiments will be conducted with touch-sensitive video monitors that allow the experimenter to select list items from thousands of digitized. The nature of representations that mediate sequence production will be studied by: (1) determining how serial expertise develops; (2) assessing a monkey's ability to "chunk" sequences it recognizes and/or produces; (3) assessing subjects' knowledge of the ordinal position of items in a list; (4) measuring the subjective organization of list items in short-term serial memory; and (5) comparing numerical and symbolic distance effects. The results of these experiments will provide non-verbal models of serial learning. The proposed research will also have two important interdisciplinary ramifications: (1) it can provide preparations for studying the neural control of serially organized behavior; and (2) the non-verbal serial tasks that will be used with monkeys could also be used with pre-verbal children in ways that would reveal the contributions that language adds to basic serial skills.

行为序列如何学习和整合？提议 研究将研究串行组织的非语言机制 通过研究其在猴子中的认知发展来行为。这个策略 消除了使研究串行行为研究复杂的两个因素 在人类主题中：语言和序列任务的经验。调查 串行学习动物还提供了比较的观点 连续组织的机制。如何学习行为序列 并将使用两种最近开发的技术来研究集成 培训猴子以制作和回忆任意和数字清单 刺激。在同时链接范式中，所有刺激和 响应的机会同时可用，这是串行的关键特征 关于人类受试者的言语学习实验的任务。自从他们 配置从步道更改为试用对象必须依靠 执行所需序列的同时表示其顺序位置。 短期连续记忆将通过 延迟匹配到成功的样本范式，其中受试者为 需要重现作为样本同时链的列表所需的。 一些列表将提供依据基础机制的实时度量 行为。拟议研究的另一个不寻常的特征是广泛的 许多主题的经验在执行任意的序列任务中 和数值刺激。实验将以触摸敏感进行 视频监视器允许实验者从数千个中选择列表项目 数字化。介导序列产生的表示的性质 将通过：（1）确定串行专业知识如何发展； （2） 评估猴子“块”序列的能力，其识别和/或 生产； （3）评估受试者在 清单； （4）在短期内测量清单项目的主观组织 连续记忆； （5）比较数值和符号距离效应。这 这些实验的结果将提供串行学习的非语言模型。 拟议的研究还将有两个重要的跨学科 后果：（1）它可以为研究神经控制提供准备 连续组织的行为； （2）非语言序列任务 也可以与猴子一起使用 将揭示语言增加基本序列技能的贡献。
