检测到的目标刺激的诱发电位的晚期分量与概率有关。文献不清楚决定性变量是顺序概率，即目标在一定数量刺激下的概率，还是时间概率，即目标在一段时间内的概率。改变列车的刺激之间的间隔，同时保持恒定的顺序概率的目标引起显着的变化，在后期组件的目标诱发电位，证明其依赖于时间的概率。同时操作时间概率和顺序概率表明时间概率是诱发电位晚期分量的决定因素。
The late components of the evoked potential to a detected target stimulus are related to probability. The literature is unclear whether the determining variable is sequential probability, the probability of a target within a number of stimuli or temporal probability, the probability of a target within a period of time. Altering the interval between the stimuli of a train while maintaining a constant sequential probability for the target caused significant changes in the late components of the target-evoked potential, demonstrating their dependence on temporal probability. Simultaneous manipulation of both temporal and sequential probability showed temporal probability to be the determining factor for the late components of the evoked potential.
