The resources allocated to a primary and secondary task are reciprocal. Subjects performed a tracking task in which the discrete displacements of the tracking cursor could be used to elicit event-related brain potentials. As the resource demands of the tracking task were increased, potentials elicited by the task-defined events increased in amplitude, whereas those elicited by secondary task auditory stimuli decreased.
分配给主要任务和次要任务的资源是相互的。受试者执行一项追踪任务，其中追踪光标的离散位移可用于诱发事件相关脑电位。随着追踪任务的资源需求增加，由任务定义事件诱发的电位幅度增加，而由次要任务听觉刺激诱发的电位则降低。
