Recent studies have demonstrated the positive effects of musical training on the perception of vocally expressed emotion. This study investigated the effects of musical training on event-related potential (ERP) correlates of emotional prosody processing. Fourteen musicians and fourteen control subjects listened to 228 sentences with neutral semantic content, differing in prosody (one third with neutral, one third with happy and one third with angry intonation), with intelligible semantic content (semantic content condition--SCC) and unintelligible semantic content (pure prosody condition--PPC). Reduced P50 amplitude was found in musicians. A difference between SCC and PPC conditions was found in P50 and N100 amplitude in non-musicians only, and in P200 amplitude in musicians only. Furthermore, musicians were more accurate in recognizing angry prosody in PPC sentences. These findings suggest that auditory expertise characterizing extensive musical training may impact different stages of vocal emotional processing.
最近的研究表明，音乐训练对声音表达情感的感知有积极影响。本研究调查了音乐训练对情绪韵律加工的事件相关电位（ERP）相关物的影响。14 名音乐家和 14 名对照组受试者听了 228 个具有中性语义内容的句子，这些句子的韵律（三分之一为中性，三分之一为高兴，三分之一为生气）不同，并且具有可理解的语义内容（语义内容条件——SCC）和不可理解的语义内容（纯韵律条件——PPC）。结果发现音乐家的 P50 振幅降低。只有非音乐家在 SCC 和 PPC 条件之间存在 P50 和 N100 振幅的差异，而只有音乐家在 P200 振幅方面存在差异。此外，音乐家在识别 PPC 句子中的生气韵律方面更为准确。这些发现表明，具有广泛音乐训练特征的听觉专业知识可能会影响声音情感处理的不同阶段。
