音乐对辨别力的影响<br>Effects of Music on the Recognition

Abstract

目的本实验探讨了情绪状态和先验概率对无意义数字串辨别的影响。方法由剪辑的3首轻音乐诱导产生愉快、中性和悲怆不同水平的情绪状态，采用信号检测论的方法进行分析。结果（1）情绪状态对个体感受性d’和主观判断标准β的影响均不显著；（2）先验概率对d’和β均无显著性影响。结论（1）个体作决策时倾向于依据个案具体信息而忽视统计信息；（2）音乐诱导情绪的效果与个体对音乐的理解程度有关，本实验并未发现音乐诱导范式的情绪效应。 Purposes: The experiment explored how the emotional state and prior probability affected the recognition of meaningless number strings. Methods: 3 music experts aroused different emotional states, including pleasure, neutrality and sadness levels. The results were analyzed using Signal Detection Theory. Results: (1) The effects of emotional state on individual sensitivity d’ and subjective judgment criterion β were not significant; (2) Prior probability had no significant effect on individual sensitivity d’ and subjective judgment criterion β. Conclusions: (1) An individual made decisions according to objective information, ignoring statistic information; (2) The emotional effect was relevant to the understanding of the individual. Under this paradigm, no emotional effect was aroused by music.
