HIPPOCAMPAL FUNCTION AND RELATIONAL CATEGORIZATION

神经心理学理论的发展是促进当有 方法和理论相互关联的非人类动物和人类的研究。一 如何发展这种相互关系，以帮助澄清 海马系统中信息处理的本质，包括 结合阿什比和他的同事们在 人类认知和决策的竞技场（阿什比和戈特，1988年）， Eichenbaum及其同事提出的海马加工理论 （Eichenbaum，1994年）。 Eichenbaum和他的同事认为， 海马体负责灵活的关系处理，而阿什比 和他的同事们开发了一种用于人类的分类任务 其中受试者学习基于以下因素对刺激显示进行最佳分类： 显示器中的特征之间的关系。很少有直接的测试 Eichenbaum和他的同事提出的理论。因此，目标 研究的目的是评估 海马的处理是正常表现所必需的， 分类任务

Development of neuropsychological theory is facilitated when there is method and theory to interrelate nonhuman animal and human studies. One means by which such interrelations might be developed, to help clarify the nature of information processing in the hippocampal system, consists of combining method and theory articulated by Ashby and his colleagues in the arena of human cognition and decision making (Ashby & Gott, 1988) with a hippocampal processing theory developed by Eichenbaum and his colleagues (Eichenbaum, 1994). Eichenbaum and his colleagues suggest that the hippocampus is responsible for flexible, relational processing while Ashby and his colleagues have developed a categorization task for use in humans where a subject learns to optimally categorize stimulus displays based on a relation between features in the displays. There are few direct tests of the theory developed by Eichenbaum and his colleagues. Therefore, the aim of the proposed research is to assess the circumstances under which hippocampal processing is required for normal performance in the Ashby categorization task.
