In the present study, the effects of Mozart's sonata K.448 on voluntary and involuntary attention were investigated by recording and analyzing behavioral and event-related potentials (ERPs) data in a three-stimulus visual oddball task. P3a (related to involuntary attention) and P3b (related to voluntary attention) were analyzed. The "Mozart effect" was showed on ERP but not on behavioral data. This study replicated the previous results of Mozart effect on voluntary attention: the P3b latency was influenced by Mozart's sonata K.448. But no change of P3a latency was induced by this music. At the same time, decreased P3a and P3b amplitudes in music condition were found. We interpret this change as positive "Mozart effect" on involuntary attention (P3a) and negative "Mozart effect" on voluntary attention (P3b). We conclude that Mozart's sonata K.448 has shown certain effects on both involuntary attention and voluntary attention in our study, but their effects work on different mechanisms.
在本研究中，通过在三刺激视觉Oddball任务中记录和分析行为数据及事件相关电位（ERP）数据，研究了莫扎特《第448号奏鸣曲》对随意注意和不随意注意的影响。分析了P3a（与不随意注意有关）和P3b（与随意注意有关）。ERP数据显示出“莫扎特效应”，但行为数据未显示。本研究重复了之前关于莫扎特效应与随意注意的结果：P3b潜伏期受莫扎特《第448号奏鸣曲》影响。但该音乐未引起P3a潜伏期变化。同时，发现音乐条件下P3a和P3b波幅降低。我们将这种变化解释为对不随意注意（P3a）的正向“莫扎特效应”和对随意注意（P3b）的负向“莫扎特效应”。我们得出结论，在我们的研究中，莫扎特《第448号奏鸣曲》对不随意注意和随意注意均显示出一定影响，但其作用机制不同。
