Describe the technique and functional aspect of the dichotic listening paradigm. 描述双耳聆听的技巧和功能。
Evidence in supporting of lateralization for language in the left hemisphere comes from researches in dichotic listening tasks. 证明左半球的语言侧化的证据来自于两耳分听研究。
By means of dichotic listening task, we can analyze the characteristics of incoming stimuli processed by the individual hemisphere. 通过两耳分听研究，我们可以分析各个半球所处理的外部刺激的特点。
In a dichotic listening test, a person sits with a set of earphones on, and through each earphone, simultaneously, comes a different sound. 在双耳两分听话试验中，被测试者要戴上耳机坐在位子上，两个耳机里会同时传出不同的声音。
Methods: The subjects were 20 patients with a CCMD-3 diagnosis of schizophrenia, and 20 healthy control subjects.Experiment 1 utilized dichotic listening task. 方法：用听觉和视觉两个行为实验，对20 例符合CCMD-3诊断标准，以阳性症状为主的男性精神分裂症患者和20名正常人作对照研究。
Results: On dichotic listening task, the schizophrenic patients showed a left ear advantage(RH) during the non-forced condition, while the healthy subjects a right ear advantage(LH). 结果：两耳分听实验结果显示，非注意条件时，精神分裂症患者为左耳（右半球）优势，而正常人则表现为右耳（左半球）优势；
