The present study was aimed at investigating selective attention in the presence of music as expressed by ERPs. The experiments were performed with 7 subjects. A two-channel auditory frequency discrimination task (target - 1000 Hz, standard - 1550 Hz tones) in a dichotic listening environment was employed. The EEG was recorded from Fz, Cz, Pz, C3 and C4. The EOG and performance data were also collected. A smaller and delayed N1 amplitude as well as changes in the two components of the processing negativity in the presence of music were found. N2 and P3 components only delay with music was observed. The changes in the level of performance were not significant.
本研究旨在通过事件相关电位(ERP)来探究在有音乐存在的情况下的选择性注意。实验由7名受试者完成。采用两通道听觉频率辨别任务(目标音为1000赫兹,标准音为1550赫兹的纯音),处于双耳分听环境中。脑电图(EEG)记录点为Fz、Cz、Pz、C3和C4。同时还收集了眼电图(EOG)和行为数据。研究发现,在有音乐存在的情况下,N1波幅更小且潜伏期延长,以及加工负波的两个成分发生了变化。仅观察到N2和P3成分在有音乐时出现潜伏期延长。行为表现水平的变化不显著。
