语言认知神经科学的一项主要工作是定义词语产生所涉及的核心认知过程的时间和空间特征。一种方法包括研究图像命名任务中语言和前语言变量的影响。到目前为止，研究已经通过因子设计检查一两个变量来分析单词生成过程中的事件相关电位（ERP）。在这里，我们通过同时研究图片命名任务中多个理论相关预测变量的影响来扩展这种方法。在公开命名 100 张图片时，记录了 31 名参与者的高密度脑电图。从图片出现到发音开始前 100 毫秒，在逐次试验的基础上提取 ERP。进行混合效应回归模型来检查哪些变量影响生产延迟和稳定电生理模式（地形图）的持续时间。结果揭示了前语言变量视觉复杂性对头皮稳定电场的早期阶段（图片呈现后 140 至 180 毫秒）的影响，这一结果与该时间段与视觉对象识别过程相关的提议一致。其他三个变量（词获取年龄、名称一致性和图像一致性）会影响响应延迟，并将 ERP 从约 380 毫秒调节到分析期结束。这些结果表明，地形分析适合单次试验 ERP 并覆盖整个处理周期，允许人们将心理语言变量产生的成本与特定稳定电生理过程的持续时间联系起来，并同时查明多个单词产生预测因子的精确时间过程。
A major effort in cognitive neuroscience of language is to define the temporal and spatial characteristics of the core cognitive processes involved in word production. One approach consists in studying the effects of linguistic and pre-linguistic variables in picture naming tasks. So far, studies have analyzed event-related potentials (ERPs) during word production by examining one or two variables with factorial designs. Here we extended this approach by investigating simultaneously the effects of multiple theoretical relevant predictors in a picture naming task. High density EEG was recorded on 31 participants during overt naming of 100 pictures. ERPs were extracted on a trial by trial basis from picture onset to 100 ms before the onset of articulation. Mixed-effects regression models were conducted to examine which variables affected production latencies and the duration of periods of stable electrophysiological patterns (topographic maps). Results revealed an effect of a pre-linguistic variable, visual complexity, on an early period of stable electric field at scalp, from 140 to 180 ms after picture presentation, a result consistent with the proposal that this time period is associated with visual object recognition processes. Three other variables, word Age of Acquisition, Name Agreement, and Image Agreement influenced response latencies and modulated ERPs from ~380 ms to the end of the analyzed period. These results demonstrate that a topographic analysis fitted into the single trial ERPs and covering the entire processing period allows one to associate the cost generated by psycholinguistic variables to the duration of specific stable electrophysiological processes and to pinpoint the precise time-course of multiple word production predictors at once.
