EEG activity of eight male volunteers was monopolarly recorded at P3 and P4 during an initial baseline and during performance of three series of cognitive tasks: one verbal, one spatial and one "mixed" demanding verbal and spatial processing. Interhemispheric correlation of the EEG activity was compared among tasks and between successful and unsuccessful trials. There was a significant main effect for success or failure of cognitive processing with increased interhemispheric correlation during unsuccessful trials regardless of their nature. There was no main effect for tasks. Interhemispheric correlation proved to be sensitive to success or failure in information processing.
在初始基线期间以及执行三组认知任务时，对八名男性志愿者的脑电图（EEG）活动进行了单极记录，记录位置为P3和P4。这三组认知任务分别是：一组语言任务、一组空间任务以及一组需要语言和空间处理的“混合”任务。对不同任务之间以及成功和失败试验之间的脑电图活动半球间相关性进行了比较。无论认知处理试验的性质如何，在失败试验期间，半球间相关性增加，认知处理的成功或失败存在显著的主效应。任务不存在主效应。半球间相关性被证明对信息处理的成功或失败敏感。
