Numerous studies have shown that the slow potentials registered in the EEG allow conclusions on changes in activation processes preceding different activities. The Bp which has so far been analysed preferably as motoric phenomenon, is in the following used to furnish evidence of activation processes preceding mental performance at a visual display terminal. The analysis reveals the relationships between the Bp and mental load, mental performance, and a varying dynamic activation. From that, conclusions can be drawn already in the phase of preparing different information processing activities on variations in central-nervous activation and most likely even on the readiness to perform and the reliability of actions.
大量研究表明，脑电图（EEG）中记录的慢电位有助于推断不同活动之前激活过程的变化。迄今为止，主要作为运动现象进行分析的Bp，在以下用于提供视觉显示终端上心理表现之前激活过程的证据。分析揭示了Bp与心理负荷、心理表现以及变化的动态激活之间的关系。由此，在准备不同信息处理活动的阶段，就可以得出关于中枢神经激活变化的结论，甚至很可能得出关于执行准备情况和行动可靠性的结论。
