最近的研究表明，前瞻记忆（PM）的意图可能不会被关闭后直接完成。残余激活导致后效，其反映为当旧意图的前PM线索散布在新任务中时对性能的干扰（即，意图失活失败，Walser等人，J Exp Psychol Learn Mem Cogn 38（4）：1030 - 1044，2012）。在本研究中，我们通过操纵任务要求（例如，工作记忆负荷）之间的意图完成和测量的后效。当工作记忆负荷较低（控制条件）时，重复PM线索试验的后效被发现，但当可用资源稀疏（工作记忆负荷条件）时，后效减少。当参与者被要求对PM提示进行反思时，随后的后效增加了。此外，自我报告的行动控制低的参与者的总体后效更大。结果表明，填充任务活动的性质决定了完成的意图的表征是不稳定的（工作记忆负荷）或加强（意图反射）。因此，新的工作记忆任务表征对已完成的意图表征的（至少部分）抑制似乎反映了已完成的意图失活的一个支持因素。
Recent studies showed that prospective memory (PM) intentions might not be deactivated directly after completion. The residual activation leads to aftereffects which are reflected as interference in performance when former PM cues of old intentions are interspersed in the new task (i.e., intention deactivation failure, Walser et al., J Exp Psychol Learn Mem Cogn 38(4):1030–1044, 2012). In the present study, we investigated potential mechanisms that might support the deactivation process of completed intentions by manipulating the task demands (e.g., working memory load) between intention completion and measurement of aftereffects. Aftereffects on repeated PM-cue trials were found when working memory load was low (control condition), but were reduced when available resources were sparse (working memory load condition). When participants were asked to reflect upon the to-be-deactivated PM cue, subsequent aftereffects were increased. Further, overall aftereffects were larger for participants low in self-reported action control. Results show that the nature of the filler-task activity determines whether the representation of the completed intention is destabilized (working memory load) or strengthened (intention reflection). The (at least partial) overwriting of completed intention representations by new working memory task representations seems therefore to reflect a supporting factor for the deactivation of completed intentions.
