本研究考察了语境学习对先前无意义的伪词的神经加工的影响。在连续5天的评价性条件反射训练中，参与者学会了将120个假词与积极、中性或消极的图片联系起来。在第二次实验中，参与者再次被呈现所有条件性假词以及40个新的假词，同时记录他们的事件相关电位(ERPs)。行为数据证实了伪词配价的成功学习。在神经水平上，早期事件相关电位的调制在P1和N1成分上可见，以区分积极条件假词和消极条件假词。LPC的调制表明，在较晚的加工阶段，与新伪词的差异是明显的。这些结果支持语境学习假说，该假说能够解释视觉单词识别中非常早期的情绪事件相关电位调节。来源定位表明，大脑内侧-额叶区域可能是这些早期价识别信号的来源，这些信号被讨论以促进自上而下的信号到感觉加工。
The present study examined the effect of contextual learning on the neural processing of previously meaningless pseudowords. During an evaluative conditioning session on 5 consecutive days, participants learned to associate 120 pseudowords with either positive, neutral or negative pictures. In a second session, participants were presented all conditioned pseudowords again together with 40 new pseudowords in a recognition memory task while their event-related potentials (ERPs) were recorded. The behavioral data confirm successful learning of pseudoword valence. At the neural level, early modulations of the ERPs are visible at the P1 and the N1 components discriminating between positively and negatively conditioned pseudowords. Differences to new pseudowords were visible at later processing stages as indicated by modulations of the LPC. These results support a contextual learning hypothesis that is able to explain very early emotional ERP modulations in visual word recognition. Source localization indicates a role of medial-frontal brain regions as a likely origin of these early valence discrimination signals which are discussed to promote top-down signals to sensory processing.
