| 摘 要： | 基于类别学习包含类别归纳、分类和认知控制3个子过程的假设, 设计了人工类别学习的新任务, 利用高密度ERP技术并结合偶极子源分析, 从纵向和横向两个方面研究了人工类别学习的神经基础与机制。结果表明, 人工类别学习涉及前扣带回、前额叶皮质和内侧颞叶等关键脑区, 并在时间序列上显示了这些脑区扮演的不同作用。基于当前发现, 我们从时-空水平上讨论了的人工类别学习的认知神经机制。

| Abstract: | Based on the hypothesis that artifact category learning consists of category induction,categorization and cognitive control,we designed a new experimental task of artifact category learning. And then using high density event-related potentials and dipole source analysis,we investigate the neural basis and mechanism. The results showed that the anterior cingulate cortex,the prefrontal cortex and the medial temporal lobe are critical to complete artificial category learning tasks,and demonstrated that the dif... |
