Event-related potentials (ERPs) were recorded during a recognition memory test for previously studied visual objects. Some studied objects were paired with the same context (landscape scenes) as at study, some were superimposed on a different studied context, and some were paired with new contexts. Unstudied objects were paired with either a studied or a new context. Three ERP memory effects were observed: an early effect elicited by all stimuli containing at least one studied component; a second effect elicited only by stimuli in which both object and context had been studied; and a third effect elicited by stimuli containing a studied object. Thus, test stimuli engaged three distinct kinds of memory-related neural activity which differed in their specificity for task-relevant features.
在一项针对先前研究过的视觉对象的识别记忆测试中记录了事件相关电位（ERP）。一些研究过的对象与学习时相同的背景（风景场景）配对，一些叠加在不同的研究背景上，还有一些与新背景配对。未研究过的对象与已研究或新的背景配对。观察到三种ERP记忆效应：由所有包含至少一个研究成分的刺激引发的早期效应；仅由对象和背景都已被研究的刺激引发的第二种效应；以及由包含已研究对象的刺激引发的第三种效应。因此，测试刺激引发了三种不同类型的与记忆相关的神经活动，它们在对任务相关特征的特异性方面存在差异。
