A current focus in the prospective memory literature is the extent to which a prospective memory task (remembering to perform a future action) interferes with ongoing activities (defined in this study as lexical decision latencies). In the present study, participants had to detect one, two, three, four, five, or six prospective memory cues. Results showed no significant increase in lexical decision latencies with one or two targets; however, significant costs emerged with three or more targets. Furthermore, task interference showed a linear increase in task costs for word trial performance but not for nonword trial performance. Practical and theoretical implications of these findings are discussed.
前瞻性记忆文献当前的一个关注点是前瞻性记忆任务（记住在未来执行某个动作）对正在进行的活动（在本研究中定义为词汇判断潜伏期）的干扰程度。在本研究中，参与者必须检测一、二、三、四、五或六个前瞻性记忆线索。结果显示，一个或两个目标的情况下，词汇判断潜伏期没有显著增加；然而，三个或更多目标时出现了显著的代价。此外，任务干扰在单词试验表现的任务代价上呈线性增加，但在非单词试验表现上并非如此。讨论了这些发现的实际和理论意义。
