在编码期间产生(例如,朗读)的项通常比没有产生(例如,默读)的项更容易记住。这种“生产效应”被解释为独特性:生产的产品比非生产的产品有更明显的特征,导致更强的检索能力。目前这项研究的目标是使用脑电(EEG)来检查生产效应的神经基础。在研究期间,参与者被呈现给他们被要求在记录脑电数据的同时默读、大声朗读或唱歌的单词。随后的记忆性能使用是/否识别测试进行测试。分析集中在每个指令条件下编码指令线索所诱发的事件相关脑电位(ERPs)。我们的数据显示,与默读相比,产生物品的记忆性能得到了增强,歌唱或朗读指令的P300事件相关电位幅度更大。我们的结果表明,P300的波幅至少受产生、发声(相对于默读)的一个方面的调节,并与产生效应的独特性解释一致。企业资源计划方法论是研究生产效果的可行工具。(SqucINFO数据库记录
Items that are produced (e.g., read aloud) during encoding typically are better remembered than items that are not produced (e.g., read silently). This "production effect" has been explained by distinctiveness: Produced items have more distinct features than nonproduced items, leading to enhanced retrieval. The goal of the current study was to use electroencephalography (EEG) to examine the neural basis of the production effect. During study, participants were presented with words that they were required to read silently, read aloud, or sing while EEG data were recorded. Subsequent memory performance was tested using a yes/no recognition test. Analysis focused on the event-related brain potentials (ERPs) evoked by the encoding instruction cue for each instruction condition. Our data revealed enhanced memory performance for produced items and a greater P300 ERP amplitude for instructions to sing or read aloud compared with instructions to read silently. Our results demonstrate that the amplitude of the P300 is modulated by at least 1 aspect of production, vocalization (singing/reading aloud relative to reading silently), and are consistent with the distinctiveness account of the production effect. The ERP methodology is a viable tool for investigating the production effect. (PsycINFO Database Record
