"Auditory neglect after right frontal lobe and right pulvinar thalamic lesions": comments on Hugdahl, Wester, and Asbjørnsen (1991) and some preliminary findings.
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.
