Distributional analyses and event-related brain potential were used to show that effects of irrelevant spatial stimulus-response correspondence consist of 2 qualitatively different automatic components that can be distinguished on the basis of their dependencies on relative response speed and on computational requirements of the primary task. One component reflects priming of the spatially corresponding response by an abrupt stimulus onset that does not depend on the nature of the primary task. This unconditional component exhibits a biphasic pattern, with initial facilitation later turning into inhibition, analogous to that found for spatial cuing in visual detection tasks. The 2nd component reflects automatic generalization of task-defined transformations of relevant stimulus information to spatial codes; this conditional component does not depend on relative response speed. Possible connectionist implementations of the conditional mechanism are discussed.
分布分析和事件相关脑电位被用于表明，无关空间刺激-反应对应关系的效应由两个性质不同的自动成分组成，这两个成分可以根据它们对相对反应速度的依赖性以及主要任务的计算要求来区分。一个成分反映了突然的刺激开始对空间对应反应的启动，这并不依赖于主要任务的性质。这个无条件成分呈现出双相模式，最初是促进作用，随后转变为抑制作用，类似于在视觉检测任务中空间线索化所发现的情况。第二个成分反映了将相关刺激信息的任务定义转换自动泛化为空间编码；这个条件成分不依赖于相对反应速度。文中讨论了条件机制可能的联结主义实现方式。
