The present study examined the effect of participants' music genre preference on the neural processes underlying evaluative and cognitive judgements of music using the event-related potential technique. To this aim, two participant groups differing in their preference for Latin American and Heavy Metal music performed a liking judgement and a genre classification task on a variety of excerpts of either music genre. A late positive potential (LPP) was elicited in all conditions between 600 and 900 ms after stimulus onset. During the genre classification task, an early negativity was elicited by the preferred compared to the non-preferred music at around 230-370 ms whereas the non-preferred genre was characterized by a larger LPP. The findings suggest that evaluative and cognitive judgements of music are accompanied by affective responses and that the valence of music may spontaneously modulate early processes of music categorization even when no overt liking judgement is required.
本研究采用事件相关电位技术，考察了参与者音乐类型偏好对音乐评价和认知判断的神经过程的影响。为此，两组参与者分别对拉丁美洲音乐和重金属音乐表现出不同的偏好，他们在各种音乐片段上执行了喜好判断和音乐类型分类任务。在刺激出现后 600 到 900 毫秒之间，在所有条件下都产生了一个正后电位（LPP）。在音乐类型分类任务中，与不喜欢的音乐相比，喜欢的音乐在大约 230-370 毫秒时产生了一个早期负波，而不喜欢的音乐类型则表现出更大的 LPP。研究结果表明，音乐的评价和认知判断伴随着情感反应，即使不需要明显的喜好判断，音乐的情绪价值也可能自发地调节音乐分类的早期过程。
