The ability to remember to execute delayed intentions is referred to as prospective memory. Previous theoretical and empirical work has focused on isolating whether a particular prospective memory task is supported either by effortful monitoring processes or by cue-driven spontaneous processes. In the present work, we advance the Dynamic Multiprocess Framework, which contends that both monitoring and spontaneous retrieval may be utilized dynamically to support prospective remembering. To capture the dynamic interplay between monitoring and spontaneous retrieval, we had participants perform many ongoing tasks and told them that their prospective memory cue may occur in any context. Following either a 20-min or a 12-h retention interval, the prospective memory cues were presented infrequently across three separate ongoing tasks. The monitoring patterns (measured as ongoing task cost relative to a between-subjects control condition) were consistent and robust across the three contexts. There was no evidence for monitoring prior to the initial prospective memory cue; however, individuals who successfully spontaneously retrieved the prospective memory intention, thereby realizing that prospective memory cues could be expected within that context, subsequently monitored. These data support the Dynamic Multiprocess Framework, which contends that individuals will engage monitoring when prospective memory cues are expected, disengage monitoring when cues are not expected, and that when monitoring is disengaged, a probabilistic spontaneous retrieval mechanism can support prospective remembering.
记忆延迟执行意图的能力被称为前瞻性记忆。以前的理论和实证工作集中于分离特定的前瞻性记忆任务是由费力的监控过程还是由线索驱动的自发过程支持。在目前的工作中,我们推进了动态多处理框架,该框架认为监控和自发检索都可以动态地用于支持前瞻性记忆。为了捕捉监控和自发检索之间的动态相互作用,我们让参与者执行许多正在进行的任务,并告诉他们他们的前瞻性记忆线索可能出现在任何环境中。在 20 分钟或 12 小时的保留间隔后,前瞻性记忆线索在三个单独的正在进行的任务中很少出现。监测模式(相对于被试间控制条件的正在进行的任务成本进行衡量)在三个环境中都是一致且稳健的。在最初的前瞻性记忆线索之前没有监测的证据;然而,那些成功自发地回忆起前瞻性记忆意图的人,从而意识到在那个环境中可以预期前瞻性记忆线索,随后进行了监测。这些数据支持动态多处理框架,该框架认为,当预期前瞻性记忆线索时,个体将参与监测;当不期望线索时,个体将停止监测;当停止监测时,概率性的自发检索机制可以支持前瞻性记忆。
