Subjects suffering from major depressive disorder were compared to normal controls on two verbal dichotic listening tasks. Although there were no significant differences between the groups on a task primarily of language perception, significant differences were obtained on a task with an attentional component. Overall performance was lower for the depressed group and ear asymmetry was reduced. Within the depressed group ear asymmetry varied according to symptomatology; withdrawal-retardation was associated with a lack of asymmetry and anxiety with a normal right ear advantage. The results were interpreted in terms of an interaction between affect and attention, and possible underlying mechanisms of cerebral hemisphere function were discussed.
将患有重度抑郁症的受试者与正常对照组在两项言语双耳分听任务上进行了比较。虽然在一项主要涉及语言感知的任务上两组之间没有显著差异，但在一项带有注意力成分的任务上获得了显著差异。抑郁症组的总体表现较低，且耳不对称性降低。在抑郁症组中，耳不对称性根据症状学而有所不同；退缩迟缓与缺乏不对称性相关，而焦虑与正常的右耳优势相关。根据情感与注意力之间的相互作用对结果进行了解释，并讨论了大脑半球功能可能的潜在机制。
