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.

神经心理学理论的发展只有在 将非人类、动物和人类研究相互联系的方法和理论。一 可以发展这种相互关系的手段，以帮助澄清 海马体系统中信息处理的本质，包括 结合了Ashby和他的同事们在 人类认知和决策领域(Ashby&Gott，1988) Eichenbaum和他的同事提出的海马体加工理论 (Eichenbaum，1994)。Eichenbaum和他的同事认为 海马体负责灵活的关系处理，而Ashby负责 他和他的同事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各项对刺激显示进行最佳分类 显示中的特征之间的关系。很少有直接测试 这一理论是由Eichenbaum和他的同事提出的。因此，目标是 建议的研究的目的是评估在什么情况下 海马神经元的处理是阿什比正常行为所必需的 分类任务。
