摘　　要：采用Scullin,Einstein和Mc Daniel(2009)的研究范式,通过改变意图激活阶段任务相对重要性、意图完成阶段注意状态,探讨已完成意图后效抑制问题。结果显示,执行功能的作用是灵活的,意图激活阶段受任务重要性影响,促进前瞻记忆任务完成;完成阶段意图后效受到抑制,分散注意通过影响执行功能的资源分配促进意图后效抑制。Intention after-effects refer to failure of deactivating completed intentions,making that completed intentions impact subsequent relative information process and cause commission errors.Two potential mechanisms facilitate successful intention deactivation.Overwriting of completed intention representation hypothesized that deactivation was depending on the difficulty of new information replacing the representation of the completed intentions.If this is correct,after-effects will increase when the representation of completed intention is stronger.Attentional-dependency account posited that monitoring stimuli associated with the completed intentions was depending on the degree to which attention was allocated to.Following this reasoning,after-effects might decrease attributing to a lack of available attentional resources.This article distinguished between these two possible hypothesizes.Modified Experiment 1 of Scullin,Einstein,&McDaniel(2009)was utilized in this research.We manipulated relative importance of the task and attention mode between participants.Experiment was divided into four phases:the training phase,the active-PM phase,the completed-PM phase and the test phase.In active-PM phase,a trial type 2(match,non-match)×relative importance of the task 2(emphasis PM task,emphasis ongoing task I)×attention mode 2(full attention,divided attention)mixed design was used,and the within-subjects factor was trial type.In the test phase,a word type 2(cues,control words)×relative importance of the task 2(emphasis PM task,emphasis ongoing task I)×attention mode 2(full attention,divided attention)mixed design was used,and the within-subjects factor was word type.Four groups can be defined,namely PM task important-full attention group and PM task important-divided attention group(emphasis PM task);ongoing task important-full attention group and ongoing task importantdivided attention group(emphasis ongoing task I).Ongoing task I was changed to color-matching task for investigating intention interference differences bet
