为了了解图片记忆力的神经相关性，在研究和测试中对受试者的图片和文字进行了系统的改变，并在提取时记录了高密度事件相关电位（ERP）。使用传统的和新的方法，结果被呈现为ERP波形，50毫秒头皮地形图，和视频剪辑，并使用t统计地形图和非参数p值图进行分析。作者发现，与呈现文字时相比，在研究或测试中呈现图片时，基于顶叶的ERP成分得到增强。一个早期的前端为基础的组成部分，增强了文字相比，在研究中提出的图片。根据这些数据，作者推测，图片的记忆力与图片增强回忆的能力有关。相比之下，在研究中，与图片相比，单词的熟悉度得到了增强。从这些结果和动态视图的记忆所提供的数据作为视频剪辑，作者提出了一个ERP模型的再认记忆。(c)2006年爱思唯尔公司All rights reserved.
To understand the neural correlates of the memorial power of pictures, pictures and words were systematically varied at study and test within subjects, and high-density event-related potentials (ERPs) were recorded at retrieval. Using both conventional and novel methods, the results were presented as ERP waveforms, 50 ms scalp topographies, and video clips, and analyzed using t-statistic topographic maps and nonparametric p-value maps. The authors found that a parietally-based ERP component was enhanced when pictures were presented at study or test, compared to when words were presented. An early frontally-based component was enhanced when words were presented at study compared to pictures. From these data the authors speculate that the memorial power of pictures is related to the ability of pictures to enhance recollection. Familiarity, by contrast, was enhanced when words were presented at study compared to pictures. From these results and the dynamic view of memory afforded by viewing the data as video clips, the authors propose an ERP model of recognition memory. (c) 2006 Elsevier Inc. All rights reserved.
