个体频繁地检索意图，但是由于正在进行的任务需求，任务的执行需要被延迟-所谓的延迟执行前瞻性记忆（PM）任务。我们研究了延迟执行范式中的佣金错误。参与者被告知PM任务已完成（PM任务已执行，现在已完成最后阶段）或取消（PM任务在引入后立即取消）。我们观察到委员会的错误和正在进行的任务表现在最后阶段，其中包括几个不相关的PM线索。在两个实验中，我们观察到显着更多的委员会错误相比，完成的意图。在实验2中，委员会的错误被消除，如果最后阶段需要分开注意，无论PM任务状态。此外，我们观察到显着更多的PM线索干扰正在进行的任务相比，完成组的取消，这表明PM任务中检索取消组，但不是在完成组。由于PM任务的检索和执行被延迟分开，结果表明，委员会的错误并不总是一个快速的，自发的检索执行序列的结果，也可能发生检索和执行时，时间上分离。
Individuals frequently retrieve an intention, but the execution of the task needs to be delayed due to ongoing task demands - so-called delay-execute prospective memory (PM) tasks. We investigated commission errors in the delay-execute paradigm. Participants were told that a PM task is finished (PM task has been executed and is now finished for a final phase) or cancelled (PM task has been cancelled immediately after introduction). We observed commission errors and ongoing task performance in the final phase which included several irrelevant PM cues. In two experiments, we observed significantly more commission errors for cancelled compared to the finished intentions. In Experiment 2, commission errors were eliminated if the final phase required divided attention, regardless of PM task status. In addition, we observed significantly more PM cue interference on the ongoing task in the cancelled compared to the finished group, indicating that the PM task was retrieved in the cancelled group but not in the finished group. As retrieval and execution of the PM task were separated by a delay, the results indicate that commission errors are not always the result of a quick, spontaneous retrieval-execution sequence and may also occur when retrieval and execution are temporally separated.
