本研究旨在探讨扩散模型漂移率参数在认知决策中的电生理相关性。82名参与者完成了一项词汇判断任务，同时测量了他们的刺激相关事件相关电位(ERP)和theta频段功率。大量的单变量方法被用来检查相关性明显的时间线。研究发现，漂移率参数的个体差异、词的情绪性漂移率和项目重复的条件漂移率的个体差异与晚期正向复合体(LPC)的幅度差异有关。没有得到与theta频段功率变化的关系。漂移率参数捕获噪声证据的信息积累，而LPC幅度被讨论以反映记忆痕迹的强度。虽然这些结果指出了一个共同的潜在认知机制来解释漂移率和LPC调制，但它们也为文字识别后视觉文字加工的时间线提供了一个新的角度。需要进一步证实结果才能批准LPC作为信息积累的神经生理标记物。Hum Brain Mapp 38：5616-5627,2017。©2017威利期刊公司。
This study was designed to explore the electrophysiological correlates of the diffusion models drift rate parameter in cognitive decision making. Eighty‐two participants completed a lexical decision task while their stimulus‐dependent event‐related potentials (ERP) and theta frequency band power were measured. A mass univariate approach was applied to examine the timeline at which correlations were evident. Individual differences in drift rate parameter and condition‐wise within‐subject differences in drift rates for word emotionality and item repetition were found to be related to amplitude differences in the late positive complex (LPC). No relations to theta frequency band power changes were obtained. The drift rate parameter captures information accumulation of noisy evidence, while LPC amplitudes are discussed to reflect the strength of a memory trace. While these results point to a common underlying cognitive mechanism to explain drift rates and LPC modulation, they also provide a new angle on the timeline of visual word processing following word identification. Further confirmations of the results are needed to approve the LPC as neurophysiological marker of information accumulation.Hum Brain Mapp 38:5616–5627, 2017. ©2017 Wiley Periodicals, Inc.
