ONTOGENY OF MEMORY--ELECTROPHYSIOLOGICAL EVIDENCE

描述(申请人摘要)：内隐记忆的个体发生： 电生理证据对成年人的研究表明，有 多个记忆系统，但对这种神经认知如何 组织发展。这是不幸的，因为任何有效的理论 内存必须考虑到系统是如何成熟和组织的。具体来说， 研究人员提出，内隐记忆可能是一种功能 比外显记忆更早发展的系统。为了更好地研究 内隐记忆的个体发育，我们建议使用事件相关电位 (ERPs)4个月、6个月和8个月婴儿重复注射 范例。当先前接触刺激时，启动就会影响 这种刺激在以后的时间里会被处理和解释。的变化 大脑皮层活动的时序或地形图由脑电活动的变化引起 重复模式将使我们能够评估不同的心理 可能影响内存性能的因素。此外，这一范式 允许我们测量认知活动的变化，而不需要任何 婴儿的行为反应。为了方便我们的 了解内隐记忆的发展，成年参与者将 将在可比的范例上运行。

DESCRIPTION (Applicant's Abstract): Ontogeny of Implicit Memory: Electrophysiological Evidence Studies with adults suggest that there are multiple memory systems, yet little is known about how this neurocognitive organization develops. This is unfortunate because any valid theory of memory must account for how the system matures and organizes. Specifically, researchers have proposed that implicit memory might be a functionally "earlier" developing system than explicit memory. In order to study the ontogeny of implicit memory, we propose to use event-related potentials (ERPs) with infants at 4-, 6-, and 8-months on a repetition priming paradigm. Priming occurs when a prior exposure to a stimulus affects how that stimulus is processed and interpreted at a later time. Changes in the timing or topography of electrocortical activity due to changes in repetition patterns will allow us to assess the different psychological factors that may influence memory performance. Moreover, this paradigm allows us to measure changes in cognitive activity without requiring any over behavioral responses by the infant. In order to facilitate our understanding of the development of implicit memory, adult participants will be run on a comparable paradigm.
