前瞻记忆意图后效中执行错误的机制

Mechanisms of commission errors in aftereffects of completed intentions

前瞻记忆意图后效是指已完成或取消的意图失活失败对当前认知任务造成的干扰。近期研究采用前瞻记忆任务范式探究意图后效的影响因素及认知机制。自发提取-抑制失败和预备性监控两种认知机制的分歧在于提取旧意图是否依赖注意资源的参与。脑成像研究也证实意图提取存在两条神经通路:自发提取通路和预备性监控提取通路。未来研究应探索兼容有意遗忘失败、旧意图再提取、抑制失败三者的研究范式以及降低执行错误的有效措施。

Aftereffects of completed intentions refer to participants continue retrieving intentions interfering with current cognitive tasks,after their failures in deactivating completed or cancelled intentions.Recent studies investigated the related factors and cognitive mechanisms in prospective memory task paradigm.Spontaneous retrieval and preparatory monitoring retrieval diverge in whether the retrieval process depends on attentional resources.Brain imaging research also showed that there are two neural pathways for intention retrieval.Further studies are necessary to explore effective approaches to reduce commission errors,and develop a new paradigm including three aspects of aftereffects of completed intentions,which are failures in intentional forgetting,retrieval of completed intentions and failures in inhibition.
