本研究探讨了语境学习，特别是情绪性条件反射如何影响词汇的神经加工，作为词汇情感内涵获得的可能关键因素。21名参与者使用评价性条件反射范式连续五天学习无意义的假词和不愉快或中性图片之间的关联。随后，被试在词汇判断范式下内隐处理所习得的情绪关联时记录事件相关电位。情感词和中性词与条件假词和一组新的假词一起呈现。条件和新的假词不同，在后期的积极复杂。在早期的时间窗口（80-120毫秒）和P300中，条件反射和中性条件刺激不同。这些结果复制ERP的影响，从情绪词识别，并表明，上下文学习，特别是评价性条件反射是适合建立情绪协会的话，并解释早期ERP的影响，情绪词识别。(C)2012 Elsevier Inc.

The present study examined how contextual learning and in particular emotionality conditioning impacts the neural processing of words, as possible key factors for the acquisition of words' emotional connotation. 21 participants learned on five consecutive days associations between meaningless pseudowords and unpleasant or neutral pictures using an evaluative conditioning paradigm. Subsequently, event-related potentials were recorded while participants implicitly processed the learned emotional relevance in a lexical decision paradigm. Emotional and neutral words were presented together with the conditioned pseudowords and a set of new pseudowords. Conditioned and new pseudowords differed in the late positive complex. Emotionally and neutrally conditioned stimuli differed in an early time window (80-120 ms) and in the P300. These results replicate ERP effects known from emotion word recognition and indicate that contextual learning and in particular evaluative conditioning is suitable to establish emotional associations in words, and to explain early ERP effects in emotion word recognition.
