The effects of attention and background verbal stimuli on event-related potentials (ERPs) following tone pips were assessed under four conditions: tone pips presented alone when attending and ignoring the tones and tone pips plus verbal stimuli when attending the tones and attending the verbal stimuli. The data were quantified in terms of the N1-P2 amplitude and the similarity (correlation) between ERPs in corresponding placements over the two hemispheres. The main results were that attention influenced the ERP amplitude only with the verbal stimuli, that interhemispheric similarity was greatest with the tones only, and that similarity was greater under the tone plus verbal stimuli condition during tone-attention instructions.
在四种条件下评估了注意力和背景言语刺激对短纯音诱发的事件相关电位（ERP）的影响：在注意和忽略短纯音时单独呈现短纯音，以及在注意短纯音和注意言语刺激时呈现短纯音加言语刺激。数据根据N1 - P2波幅以及两个半球相应位置ERP之间的相似性（相关性）进行量化。主要结果是，注意力仅在言语刺激时影响ERP波幅，仅在短纯音时半球间相似性最大，并且在短纯音加言语刺激条件下的短纯音注意指令期间相似性更大。
