采用与感觉记忆相关的事件相关脑电位成分--失配负波，研究了选择性注意在听觉模式加工中的作用。参与者对指定耳朵中交替音调模式的变化做出反应，而在另一只耳朵中呈现类似的听觉模式。参与者在阅读一个钩子时也会看到相同的序列（不需要回答）。在所有条件下，模式的变化引起了失配负波（MMN），在刺激后160-220 ms达到峰值。MMN的波幅随注意力的变化而变化：注意耳对偏离刺激的反应幅度高于注意耳或阅读时对偏离刺激的反应幅度。结果表明，选择性注意调节听觉模式记忆。
The role of selective attention on auditory pattern processing was investigated using the mismatch negativity, an event-related brain potential component associated with sensory memory. Participants responded to changes in an alternating tone pattern in a designated ear while a similar auditory pattern was presented in the opposite ear. Participants were also presented with the same sequences while reading a hook (no response required). In all conditions, changes in the pattern elicited a mismatch negativity (MMN) that peaked at 160-220 ms poststimulus. MMN amplitude varied with attention: the amplitude was higher in response to deviant stimuli presented in the attended ear than to the deviant stimuli presented in the unattended ear or juring reading. The results show that selective attention modulates auditory pattern memory.
