语言和音乐是人类最独特的两种认知能力，在歌曲中结合在一起，使其成为比较语音和音乐认知的生态模型。本研究旨在确定歌曲中的词和旋律是交互加工还是独立加工，并考察注意对歌曲中的词和旋律加工的影响。事件相关脑电位（ERP）和行为数据记录，而非音乐家听唱的话对（启动和目标）在四个实验条件：相同的词，相同的旋律;相同的词，不同的旋律;不同的词，相同的旋律;不同的词，不同的旋律。参与者被要求注意单词或旋律，并执行相同/不同的任务。在这两个注意力的任务，不同的词的目标引起了N400组件，根据先前的结果预测。最有趣的是，不同的旋律（用同一个词唱）引发了N400成分，然后是后期的积极成分。最后，ERP和行为数据收敛在显示的语言和旋律的尺寸唱的话之间的相互作用。N400效应是一个公认的语义加工标记，它被歌曲中的音乐旋律所调制，这一发现表明音乐特征的变化会影响歌唱语言中的文字加工。单词和旋律之间的相互作用的影响进行了讨论，在语音/语义方面的语言和音乐的旋律/谐波方面之间的共享神经处理资源的证据。
Language and music, two of the most unique human cognitive abilities, are combined in song, rendering it an ecological model for comparing speech and music cognition. The present study was designed to determine whether words and melodies in song are processed interactively or independently, and to examine the influence of attention on the processing of words and melodies in song. Event-Related brain Potentials (ERPs) and behavioral data were recorded while non-musicians listened to pairs of sung words (prime and target) presented in four experimental conditions: same word, same melody; same word, different melody; different word, same melody; different word, different melody. Participants were asked to attend to either the words or the melody, and to perform a same/different task. In both attentional tasks, different word targets elicited an N400 component, as predicted based on previous results. Most interestingly, different melodies (sung with the same word) elicited an N400 component followed by a late positive component. Finally, ERP and behavioral data converged in showing interactions between the linguistic and melodic dimensions of sung words. The finding that the N400 effect, a well-established marker of semantic processing, was modulated by musical melody in song suggests that variations in musical features affect word processing in sung language. Implications of the interactions between words and melody are discussed in light of evidence for shared neural processing resources between the phonological/semantic aspects of language and the melodic/harmonic aspects of music.
