我们研究了分散注意对前瞻记忆意图自发提取的影响。被试在词汇判断实验的某些环节中进行了一个包含前瞻记忆需求的词汇判断任务和一个分散注意任务。在所有的实验中，监控是非常不鼓励的，我们没有观察到参与者参与监控过程的证据。在实验1中，执行一个中等要求的分散注意任务（数字检测任务）并没有影响前瞻记忆的表现。在实验2中，执行更具挑战性的分散注意力任务（随机数生成）损害前瞻性记忆。实验3表明，当前瞻记忆线索在知觉上显著时，这种损害被消除。两者合计，结果表明，自发检索不是自动的，具有挑战性的分散注意力的任务干扰自发检索，而不是与检索的意图的执行。
We examined the effects of divided attention on the spontaneous retrieval of a prospective memory intention. Participants performed an ongoing lexical decision task with an embedded prospective memory demand, and also performed a divided-attention task during some segments of lexical decision trials. In all experiments, monitoring was highly discouraged, and we observed no evidence that participants engaged monitoring processes. In Experiment 1, performing a moderately demanding divided-attention task (a digit detection task) did not affect prospective memory performance. In Experiment 2, performing a more challenging divided-attention task (random number generation) impaired prospective memory. Experiment 3 showed that this impairment was eliminated when the prospective memory cue was perceptually salient. Taken together, the results indicate that spontaneous retrieval is not automatic and that challenging divided-attention tasks interfere with spontaneous retrieval and not with the execution of a retrieved intention.
