自我损耗对基于时间前瞻记忆的影响

采用Stroop任务和前瞻记忆双任务实验范式，比较不同自我损耗条件对被试基于时间前瞻记忆（TBPM）的影响，及其对TBPM的加工阶段和成分的作用。然后通过添加外部时钟监控条件，探讨外部时钟是否可以减少自我损耗对TBPM的消极影响，以及自我损耗对时钟监控情况的作用。结果表明：（1）在内部控制条件下，自我损耗会严重影响TBPM的表现，高损耗组的TBPM成绩显著低于低损耗组，另外，自我损耗主要干扰前瞻记忆的前瞻成分和TBPM的第三个加工阶段。（2）在外部控制条件下，自我损耗没有降低TBPM的表现，说明外部时钟可以降低自我损耗对TBPM的消极影响。（3）自我损耗使个体呈现出不同的时钟监控模式，且邻近目标时间内的时钟监控次数与TBPM成绩呈显著正相关。

The Effect of Ego-Depletion on Time-Based Prospective Memory

The present study used the Stroop task and the prospective memory dual-task paradigm to compare the effect of ego-depletion conditions on Time-Based Prospective Memory (TBPM), as well as its effects on the processing stages and components of TBPM. By adding external clock monitoring, the present study examined whether the external clock reduces the negative impact of ego-depletion on TBPM and the effect of self-depletion levels on clock monitoring style. The results showed that: 1) With internal controls, ego-depletion would seriously affect the performance of TBPM. The TBPM outcome of the high ego-depletion group was significantly lower than that of the low ego-depletion group. In addition, ego-depletion mainly interfered with the prospective component and the third stage of TBPM processing. 2) With external controls, the TBPM performances were not significantly different between the two ego-depletion groups, indicating that the external clock could reduce the negative effect of ego-depletion on TBPM. 3) Ego-depletion levels could lead to different clock monitoring styles, and the numbers of clock monitoring around the target time were positively correlated with the performance of TBPM.
