The aim of this study was to expand our knowledge of the influence of emotional valence on visual word recognition by answering two questions. The first was to examine whether the emotional valence effect is sensitive to different types of task requirements, and the second was to examine whether words polysemy can modulate the effect of emotional valence. For this purpose, we manipulated orthogonally emotional valence (negative, positive and neutral words) and polysemy (polysemous vs. non polysemous words) in two versions of the lexical-decision task (one with legal nonwords and one with illegal nonwords). Results showed an effect of task: emotional valence and polysemy influenced lexical decision latencies only in the legal version of the lexical-decision task. Furthermore, results showed that the effect of polysemy was dependant on emotional valence. We observed a facilitation of polysemy for neutral words but not for emotional ones. Finally this experiment also showed that polysemy modulates the emotional valence effect. The facilitation observed for non polysemous emotional words compared to non polysemous neutral words disappeared for polysemous words. These findings fit with other studies showing facilitation for emotional word recognition and allow conclusions concerning the role of semantics on emotional word recognition.
本研究的目的是通过回答两个问题来扩展我们对情绪效价对视觉单词识别影响的认识。第一个问题是检验情绪效价效应是否对不同类型的任务要求敏感，第二个问题是检验单词的多义性是否能调节情绪效价的影响。为此，我们在两种版本的词汇判断任务（一种使用合法非词，另一种使用非法非词）中，对情绪效价（消极、积极和中性词）和多义性（多义词与非多义词）进行了正交操纵。结果显示了任务效应：情绪效价和多义性仅在词汇判断任务的合法版本中影响词汇判断潜伏期。此外，结果表明多义性的影响取决于情绪效价。我们观察到中性词存在多义性促进作用，而情绪词则没有。最后，该实验还表明多义性调节了情绪效价效应。与非多义中性词相比，非多义情绪词所观察到的促进作用在多义词中消失了。这些发现与其他显示情绪词识别存在促进作用的研究相符，并有助于得出关于语义在情绪词识别中作用的结论。
