采用oddball范式，对10名听力正常的年轻人进行事件相关电位测试。频繁信号（90%概率）是75 dB nHL的1000 Hz短纯音，而古怪信号（10%概率）是60 dB nHL的类似短纯音。模拟或控制条件，其中频繁和古怪的信号都是60 dB nHL也运行。受试者除了安静地躺在测试间的小床上外，没有得到任何指示。他们在整个测试过程中都保持清醒。在第一次治疗后至少24小时的第二次治疗中重复相同的程序。在模拟条件下，从奇数（60 dB nHL）平均诱发电位（AEP）中减去频繁（60 dB nHL）几乎得到一条直线。然而，频繁的减法（75 dB nHL）AEP from the oddball（60 dB nHL）AEP显示负差异，峰值约为175 ms。从实验条件的60 dB nHL奇数中减去在模拟条件下获得的频繁或奇数AEP也在约175 ms处产生负峰值，此外，较小的负差异，峰值约为75 ms。观察结果在各阶段一致。
An oddball paradigm was used to elicit event-related potentials from 10 normal-hearing young adult subjects. The frequent signal (90% probability) was a 1000 Hz tone burst at 75 dB nHL and the oddball signal (10% probability) was a similar tone burst at 60 dB nHL. A mock or control condition in which both frequent and oddball signals were 60 dB nHL also was run. The subjects were given no instructions other than to lie quietly on a cot in a test booth. They were awake throughout the test session. The identical procedure was repeated in a second session at least 24 hr after the first. Subtraction of the frequent (60 dB nHL) from the oddball (60 dB nHL) averaged evoked potential (AEP) in the mock condition yielded virtually a straight line. However, subtraction of the frequent (75 dB nHL) AEP from the oddball (60 dB nHL) AEP revealed a negative difference that peaked at about 175 ms. Subtraction of either the frequent or the oddball AEP obtained in the mock condition from the 60 dB nHL oddball of the experimental condition also produced a negative peak at about 175 ms and, in addition, a smaller negative difference that peaked at about 75 ms. Observations were consistent across sessions.
