Prospective memory research almost exclusively examines remembering to execute an intention, but the ability to forget completed intentions may be similarly important. We had younger and older adults perform a prospective memory task (press Q when you see corn or dancer) and then told them that the intention was completed. Participants later performed a lexical-decision task (Phase 2) in which the prospective memory cues reappeared. Initial prospective memory performance was similar between age groups, but older adults were more likely than younger adults to press Q during Phase 2 (i.e., commission errors). This study provides the first experimental demonstration of event-based prospective memory commission errors after all prospective memory tasks are finished and identifies multiple factors that increase risk for commission errors.
前瞻性记忆研究几乎专门研究记住执行意图，但忘记已完成意图的能力可能同样重要。我们让年轻和年长的成年人执行一个前瞻性记忆任务（当你看到玉米或舞者时按 Q），然后告诉他们任务已经完成。参与者随后执行词汇决策任务（第二阶段），其中前瞻性记忆线索再次出现。在初始阶段，两个年龄组的前瞻性记忆表现相似，但与年轻成年人相比，年长成年人在第二阶段更有可能按 Q（即，出现错误）。这项研究首次在所有前瞻性记忆任务完成后，提供了基于事件的前瞻性记忆错误的实验证明，并确定了多个增加错误风险的因素。
