We take issue with the claim recently made in this journal that extinction of left ear input during dichotic, but not monaural, stimulus presentation demonstrates "auditory attentional neglect" (Hugdahl, Wester, & Asbjørnsen, 1991). We also report on a patient suffering from unilateral visual neglect, who shows extinction under dichotic, but not monaural, conditions of stimulus presentation but this is not confined to one ear. Although this patient denies hearing both of two dichotically presented words, he recognizes the extinguished stimulus when given a forced-choice recognition task.
我们对该期刊最近提出的一项主张表示异议，即在双耳而非单耳刺激呈现过程中左耳输入的消退证明了“听觉注意忽视”（Hugdahl、Wester和Asbjørnsen，1991）。我们还报告了一名患有单侧视觉忽视的患者，他在双耳而非单耳刺激呈现条件下表现出消退现象，但这并不局限于一只耳朵。尽管该患者否认听到了双耳呈现的两个单词中的任何一个，但在进行强制选择识别任务时，他能识别出被消退的刺激。
