Abstract: This study included two experiments using the classical double-task PM paradigm. The aim is explored that sufficient exposure to the target prior to its being designated as such may aid detection of that target, thereby improving PM in the face of demanding ongoing activities. The results of experiment 1 showed that using both the strict and lenient criterion method, the main effect of target pre-exposure was significant. The results of experiment 2 showed that using both of the strict and lenient criterion method, PM score performed decreasing tendency from high to low level of target pre-exposure. In conclusion, the current study demonstrated that the targets exposing prior to the PM instructions generally improved PM performance, and target pre-exposure eliminated nearly all failures to remember the intended action. PM performance became better as target pre-exposure level rises. According to these results, the simple activation model was supported.

摘要： 采用双任务实验范式，以大学生为被试。实验一探讨通过在前瞻记忆任务指导语之前，对靶目标充分学习，达到靶目标的预曝光，研究靶目标预曝光对基于事件的前瞻记忆的影响。实验二探讨不同曝光率的靶目标预曝光对前瞻记忆的影响。结果表明：（1）靶目标预曝光能够提高前瞻记忆的成绩；（2）靶目标预曝光率越高，前瞻记忆成绩越好；（3）靶目标预曝光能够减少注意资源的占用。
