在演讲过程中，对几个事件的描述的计划需要对这些事件进行口头排序。在这个过程中，说话人可以在不同类型的时间连接词之间进行选择，比如‘之前’X做了A，Y做了B‘或’Y做了B，X做了A‘之后。为了捕捉这种线性化过程的神经事件，我们测量了母语为德语的人的事件相关电位(ERP)。通过在视频屏幕上呈现两张图片的序列来诱导发声。每幅图片由与特定动作相关联的对象组成(例如，书=阅读)。一种彩色发声提示，表示按时间顺序(例如红色提示：我开车后，我读了一本书)或颠倒顺序(黄色提示)描述与物体相关的两个动作的顺序。从发声提示开始后的180ms开始，两种情况下的脑电位显示出可靠的差异，而在发声提示后的状态下，ERPs更负。这一“之前/之后”的差异显示了180到230毫秒之间的额叶-中央分布。从300ms开始，观察到顶叶的分布。后一种效应被解释为P300反应的一个实例，众所周知，P300反应受到任务难度的调节。显性句产生前的事件相关电位对概念线性化非常敏感。早期观察到的更多额叶中心分布的变异可以被解释为参与了根据指令对事件进行排序所需的工作记忆。较晚的顶叶分布变异与线性化的复杂性有关，在更新工作记忆中的概念时，非时间顺序的要求更高。
During speech production the planning of a description of several events requires, among other things, a verbal sequencing of these events. During this process, referred to as linearization during conceptualization, the speaker can choose between different types of temporal connectives such as 'Before' X did A, Y did B' or 'After' Y did B, X did A'. To capture the neural events of such linearization processes, event-related potentials (ERP) were measured in native speakers of German. Utterances were elicited by presenting a sequence of two pictures on a video screen. Each picture consists of an object that is associated with a particular action (e.g. book = reading). A coloured vocalization cue indicated to describe the sequence of two actions associated with the objects in chronological (e.g. red cue: 'After' I drove the car, I read a book) or reversed order (yellow cue). Brain potentials showed reliable differences between the two conditions from 180 ms after the onset of the vocalization prompt, with ERPs from the 'After' condition being more negative. This 'Before/After' difference showed a fronto-central distribution between 180 and 230 ms. From 300 ms onwards, a parietal distribution was observed. The latter effect is interpreted as an instance of the P300 response, which is known to be modulated by task difficulty. ERPs preceding overt sentence production are sensitive to conceptual linearization. The observed early, more fronto-centrally distributed variation could be interpreted as involvement of working memory needed to order the events according to the instruction. The later parietal distributed variation relates to the complexity in linearization, with the non-chronological order being more demanding during the updating of the concepts in working memory.
