在60名正常人和20名脑损伤患者中测试了三种不同的声音物体识别能力：（1）在不同线索上分离声音物体的能力（ii）通过判断两个不同的声音样本是否属于同一对象来对真实的对象的声音进行语义识别;以及（iii）通过多项选择反应测试判断的真实的物体的声音的语义识别。在12名患者中，参与听觉识别的不同能力被分别破坏，并且以一种有利于平行而不是分层处理的方式说话。非言语听觉识别缺陷与失语症或病变侧之间没有强相关性。版权所有（C）1996 Elsevier Science Ltd.
Three different aptitudes involved in sound object recognition were tested in 60 normal subjects and 20 brain-damaged patients: (i) capacity to segregate sound objects on different cues (intensity steps, coherent temporal modulations or signal onset synchrony); (ii) asemantic recognition of sounds of real objects by judging whether two different sound samples belonged to the same object; and (iii) semantic identification of sounds of real objects as judged by means of a multiple choice response test. In 12 patients, different aptitudes involved in auditory recognition were disrupted separately and in a way which speaks in favour of parallel rather than hierarchical processing. There was no strong association between deficits in non-verbal auditory recognition and aphasia or the side of lesion. Copyright (C) 1996 Elsevier Science Ltd.
