最近关于事件感知的研究表明，当事件发生变化时，感知处理会增强。一个重要的问题是这些变化如何影响其他信息的处理方式，特别是在双任务执行期间。在这项研究中，参与者在对不相关的背景场景进行编码的同时，监视了一系列干扰项目，以寻找偶尔的目标。偶然目标的出现可能会对次要任务产生两种相反的影响：它可能会将注意力从第二个任务上转移开，或者，作为正在进行的事件的变化，它可以提高次要任务的绩效。结果与第二种可能性一致。对与目标同时呈现的场景的记忆优于对目标之前或之后的场景的记忆。当主要检测任务涉及视觉特征奇怪检测、听觉奇怪检测和视觉颜色形状联合检测时，观察到这种效应。当检测任务被省略以及需要任意响应映射时，它就被消除了。偶尔出现的与任务相关的事件似乎会触发时间定向反应，从而促进同时参与的信息的处理（注意力增强效应）。
Recent work on event perception suggests that perceptual processing increases when events change. An important question is how such changes influence the way other information is processed, particularly during dual-task performance. In this study, participants monitored a long series of distractor items for an occasional target as they simultaneously encoded unrelated background scenes. The appearance of an occasional target could have two opposite effects on the secondary task: It could draw attention away from the second task, or, as a change in the ongoing event, it could improve secondary task performance. Results were consistent with the second possibility. Memory for scenes presented simultaneously with the targets was better than memory for scenes that preceded or followed the targets. This effect was observed when the primary detection task involved visual feature oddball detection, auditory oddball detection, and visual color-shape conjunction detection. It was eliminated when the detection task was omitted, and when it required an arbitrary response mapping. The appearance of occasional, task-relevant events appears to trigger a temporal orienting response that facilitates processing of concurrently attended information (Attentional Boost Effect).
