Cognitive Neuroscience

科学家们经常试图将人类记忆的编码、存储和提取阶段分离出来，但这些阶段之间的相互作用极大地影响了我们的记忆。例如，课程先决条件中的相关记忆有助于我们记住演讲材料，引导性问题可以永久地改变目击者检索的记忆。我的研究调查了这种编码-检索的相互作用。使用新兴的大脑成像方法来跟踪检索记忆的神经签名，我观察记忆如何相互作用，并将相互作用与参与者的大脑解剖结构联系起来。这项工作可能会产生增强的教育技术，减弱侵入性记忆的方法，对脑损伤影响的预测，以及对大脑结构如何支持记忆的理解。

Scientists frequently attempt to isolate encoding, storage, and retrieval stages of human memory, but interactions among these stages dramatically influence what we remember. For example, relevant memories from course prerequisites help us retain lecture material, and leading questions can permanently alter eyewitnesses retrieved memories. My research investigates such encoding-retrieval interactions. Using emerging brain imaging methods to track the neural signature of retrieved memories, I observe how memories interact, and link interactions to participants brain anatomy. This work may yield enhanced educational techniques, methods for attenuating intrusive memories, predictions about brain injury impacts, and understanding of how brain structures support memory.
