【摘要】 前瞻记忆(Prospective Memory)是指在未来恰当的时间或情境下,在没有直接外部提示的情况下,执行事先计划好的事件或活动的记忆。前瞻记忆意向后效应(Aftereffect of Completed Intention)是前瞻记忆任务结束后,不需要再执行时,原来前瞻记忆目标线索的重复出现所导致的重复执行错误甚至进行中任务反应时增加。研究采用重复前瞻记忆线索范式(repeated PM cue paradigm)第一个阶段为前瞻记忆阶段,被试需要执行进行中任务和前瞻记忆任务,第二个阶段为前瞻记忆任务完成阶段仅执行进行中任务,前瞻记忆目标线索会再次重复出现,此时被试不需要再执行前瞻反应只需将目标线索作为进行中任务刺激反应。探讨进行中任务对不同类型前瞻记忆意向后效应的影响以及前瞻记忆意向后效应的认知加工机制,实验为3(单一进行中任务:汉字真假判断任务,汉字结构判断任务、变化进行中任务:顺序变化判断任务)×2(前瞻记忆类型:习惯性前瞻记忆、非习惯性前瞻记忆)的被试间设计。结果发现:前瞻记忆完成阶段进行中任务对意向后效应有重要影响,相比于单一进行中任务,变化进行中任务会使重复执行错误增加;同时当进行中任务变化时,相比于非习惯性前瞻记忆,习惯性前瞻记忆完成阶段进行中任务反应时增加,说明意向后效应受可利用的认知资源制约;研究支持控制加工。更多还原

【Abstract】 Previous studies have paid attention to performing an action when intention to be delayed. In fact, recently some evidence has suggest that inhibitory failures should play no role in the occurrence of prospective memory errors in response to cues that are associated with completed intention. Here we investigated whether ongoing task change bring more commission errors as a results of the lack of cognitive resources and then whether PM types interacted with ongoing tasks effect on the aftereffects of completed intention. In Experiment, we recruited 140 participants and followed a 3(single ongoing task: lexicon decision task, structure decision task、change ongoing task: sequence change ongoing task) × 2(PM Types: habitual prospective memory、no-habitual prospective memory)between-subjects design to address the above issues. Firstly, 120 participants were divided into 6 groups. Then one group which only perform in ongoing tasks, The dependent variables were the false alarm rate when the repeated prospective memory cues appear again and reaction time as well as the ongoing tasks. The results showed:(1) the interaction between ongoing tasks and PM types was significant, while sequence change ongoing task showed lower ongoing tasks response times with habitual prospective memory completed intention than sequence change ongoing task with no-habitual prospective memory.(2). sequence change ongoing task come into being bring more commission errors than single ongoing task,regardless of PM types. In conclusions whether there is sufficient cognitive resource to suppress commission errors is one of the most important factors that affect the aftereffect of completed intentions to treat. Changes in ongoing task will result in more commission errors. The result supported multiprocess view更多还原
