最近的一项研究表明，当视觉环境排除了记忆过程的运作时（例如，当显示元素每100毫秒改变一次位置时），观察者对外部世界的视觉探索可以不受损害地进行。这项研究的一个理论限制是，干扰物是视觉搜索过程中唯一有可能被标记的元素。本研究试图澄清遗忘搜索假说，通过调查是否记忆过程可以引导搜索在其他情况下，目标也有可能被标记。因此，重复以前的研究的实验条件上升一个不同的搜索任务，其中观察员必须决定是否有一个或两个目标之间的变量数量的类似干扰。在这些搜索条件下，本研究结果为记忆过程指导视觉搜索提供了强有力的证据。
A recent study has suggested that observers' visual explorations of the external world can proceed unimpaired when the visual environment precludes the operation of memory processes (as, for instance, when the display elements change locations every 100 ms). One theoretical limitation of this study was that distractors were the only elements that had the potential to be tagged during visual search. The present study sought to clarify the amnesic-search hypothesis by investigating whether memory processes can guide search in other contexts in which the targets also have the potential to be tagged. Accordingly, the experimental conditions of the previous study were repeated rising a different search task in which observers had to decide whether one target or two were present among a variable number of similar distractors. Under these search conditions, the present findings provided strong evidence that memory processes carl guide visual search.
