The multiprocess view proposes that both strategic and automatic processes can support prospective memory. In three experiments, we embedded a prospective memory task in a lexical decision task; cues were either highly associated with response words or had no relation. Analyses of RTs on ongoing task trials indicated that (1) prospective memory was more dependent on the allocation of resources immediately prior to cue presentation under conditions of low association in comparison with high association and (2) processes engaged on cue trials were more resource demanding under conditions of low association in comparison with high association. These data support the claim of the multiprocess view that prospective memory can be more resource demanding under some task conditions in comparison with others. However, the prospective memory performance data were less supportive, with declines in prospective memory due to task-importance and cue-frequency manipulations comparable across the low- and high-association conditions. Taken together, these results have implications for two prominent theories of prospective memory.
多进程观点认为，策略性和自动性过程都可以支持前瞻记忆。在三个实验中，我们将一个前瞻记忆任务嵌入到一个词汇判断任务中；线索要么与反应词高度相关，要么毫无关系。对正在进行的任务试验的反应时分析表明：（1）与高关联条件相比，在前瞻记忆中，低关联条件下，线索呈现前的资源分配对前瞻记忆的依赖性更强；（2）与高关联条件相比，低关联条件下，线索试验中所涉及的过程对资源的需求更大。这些数据支持了多进程观点的主张，即与其他一些任务条件相比，前瞻记忆在某些任务条件下对资源的需求可能更大。然而，前瞻记忆的表现数据支持力度较小，因为在低关联和高关联条件下，由于任务重要性和线索频率操作导致的前瞻记忆下降程度相当。综上所述，这些结果对两个重要的前瞻记忆理论具有启示意义。
