目标：本研究旨在确定是否可以使用事件相关电位（ERP）来测量识别/熟悉性记忆，以响应计算机改编版本的常用非言语记忆评估工具。如果成功的话，产生的ERP将进一步我们的认知记忆的神经生理学的知识，并可用于个人的语言和/或非语言沟通能力受损的认知评估电池。连续视觉记忆测试。Lutz，FL：Psychological Assessment Resources; 1988]并离线检查识别记忆旧/新效应。行为表现也进行了比较与性能的替代形式的测试下，标准的行政procedures.Results：ERP旧（重复）的视觉设计中的CVMT是更积极的去比那些新的设计，并反映了早期额叶和后期顶叶旧/新的影响，通常报道的识别记忆文献。从计算机适应和标准管理版本的CVMT的行为结果显示出显着correlation.Conclusions：计算机适应ERP版本的CVMT提供了一种方法来直接评估，使用神经生理反应，认知过程与识别记忆所测量的CVMT。这项研究的结果有助于将实验性神经影像学研究产生的记忆功能和神经生理学特征与传统的临床神经心理学评估联系起来。(c)2007年国际临床神经生理学联合会。由Elsevier爱尔兰有限公司出版。保留所有权利。
Objective: This study sought to determine if recognition/familiarity memory can be measured using event-related potentials (ERP) in response to a computer-adapted version of a commonly used non-verbal memory assessment instrument. If successful, resulting ERP would further our knowledge of the neurophysiology of recognition memory and could be used in a cognitive assessment battery for individuals whose capacity for verbal and/or non-verbal communication is impaired.Methods: Behavioral and ERP responses were recorded during performance on a computer-adapted version of the Continuous Visual Memory Test (CVMT) [Trahan DE, Larrabee GJ. Continuous Visual Memory Test. Lutz, FL: Psychological Assessment Resources; 1988] and examined offline for recognition memory old/new effects. Behavioral performance was also compared with performance on an alternate form of the test under standard administration procedures.Results: ERP to old (repeated) visual designs in the CVMT were more positive-going than those to new designs and reflected by both early frontal and late parietal old/new effects as commonly reported in the recognition memory literature. The behavioral results from the computer-adapted and standard administration versions of the CVMT showed a significant correlation.Conclusions: The computer-adapted ERP version of the CVMT provides a way to directly assess, using neurophysiological responses, the cognitive processes associated with recognition memory as measured by the CVMT.Significance: The results from this study contribute to linking the functional and neurophysiological profile of memory produced by experimental neuroimaging research with traditional clinical neuropsychological assessment.
