Retrieving information from long-term memory can lead people to forget previously irrelevant related information. Some researchers have proposed that this retrieval-induced forgetting (RIF) effect is mediated by inhibitory executive-control mechanisms recruited to overcome interference. We assessed whether inhibition in RIF depends on executive processes. The RIF effect observed in a standard retrieval-practice condition was compared to that observed in two different conditions in which participants had to perform two concurrent updating tasks that demanded executive attention. Whereas the usual RIF effect was observed when retrieval practice was performed singly, no evidence of forgetting was found in the dual-task conditions. Results strongly suggest that inhibition involved in RIF is the result of executive-control processes.
从长期记忆中提取信息可能会导致人们忘记之前无关的相关信息。一些研究人员提出，这种提取诱发遗忘（RIF）效应是由为克服干扰而招募的抑制性执行控制机制介导的。我们评估了RIF中的抑制是否依赖于执行过程。将标准提取练习条件下观察到的RIF效应与另外两种条件下观察到的效应进行了比较，在这两种条件下，参与者必须同时执行两项需要执行注意力的更新任务。当单独进行提取练习时，观察到了通常的RIF效应，而在双重任务条件下未发现遗忘的证据。结果有力地表明，RIF中涉及的抑制是执行控制过程的结果。
