DESCRIPTION (provided by applicant): This project investigates the neural bases of abstract rule learning and exemplar-specific learning in the Artificial Grammar (AG) learning task. It is hypothesized that the caudate is involved in abstract rule learning and the hippocampus is involved in exemplar-specific learning. This project will also examine whether the AG task is an implicit or explicit learning task. Although it is typically characterized as an implicit task, there is both neural and behavioral evidence that suggests that some of the learning acquired may be acquired explicitly. Finally, the project will examine the performance of Parkinson's Disease patients on this learning task. Because of the specific methodological design used, their ability to learn abstract rules and to use exemplar-specific information can be independently examined. Together, these experiments will contribute to our fundamental knowledge of learning, and this knowledge should, in turn, be used to further the development of treatments and diagnostic tests for patient populations.

描述(申请人提供)：这个项目调查了人工语法(AG)学习任务中抽象规则学习和特定样本学习的神经基础。假设尾状核参与抽象规则学习，海马体参与样例特定学习。本项目还将考察AG任务是内隐还是外显的学习任务。尽管它通常被描述为内隐任务，但有神经和行为证据表明，一些习得的知识可能是显性习得的。最后，该项目将检查帕金森氏症患者在这项学习任务中的表现。由于所使用的具体方法设计，他们学习抽象规则和使用样本特定信息的能力可以独立检查。总而言之，这些实验将有助于我们学习的基本知识，这些知识反过来应该被用来进一步发展针对患者群体的治疗和诊断测试。
