疼痛对时间性前瞻记忆的影响

The Effects of Pain on Time-based Prospective Memory

目的：探讨实验室诱发疼痛以及背景任务难度对个体执行时间性前瞻记忆的影响。方法：使用冷压痛任务模拟临床疼痛,对48名大学生进行施测,实验采用2（疼痛操作：疼痛,非疼痛）×2（任务难度：低难度,高难度）的混合设计。结果：对于前瞻任务的正确率,疼痛操作的主效应显著,即疼痛条件下,时间性前瞻记忆的成绩显著差于非疼痛条件（F=8.29,P〈0.01）。任务难度的主效应也显著,即低难度任务下,时间性前瞻记忆的成绩优于高难度任务条件（F=11.45,P〈0.001）。对于背景任务的正确率,疼痛操作的主效应显著（F=27.17,P〈0.001）,任务难度的主效应显著（F=51.29,P〈0.01）;对于背景任务的反应时,疼痛操作的主效应显著（F=8.09,P〈0.01）,任务难度的主效应显著（F=11.39,P〈0.01）结论：疼痛和任务难度对时间性前瞻记忆的执行都存在负性影响。

Objective：To explore the impacts of induced-pain and the difficulty of task on time-based prospective memory.Methods：Totally 48 college students were administrated cold pressor test and at the same time they performed time-based prospective memory task.The experiment conformed to a 2（pain operation：pain vs.no-pain）×2（task difficulty：low vs.high）mixed design.Results：For the accuracy rate of the prospective memory,the main effect of pain operation was significant,the performance of the pain condition was worse than that of the no-pain condition（F=8.29,P〈0.01）.The main effect of task difficulty was also significant,the accuracy rate of low-difficulty condition was higher than that of high-difficulty condition（F=11.45,P〈0.001）.For the accuracy rate of the ongoing task,the main effect of pain operation was significant（F=27.17,P〈0.001）.The performance of pain condition was significantly worse than that of control condition.The main effect of task difficulty was also significant（F=51.29,P〈0.001）.For the reaction time of ongoing task,the main effect of pain operation was significant（F=8.09,P〈0.01）.The main effect of task difficulty was also significant（F=11.39,P〈0.01）.Conclusion：Pain and task difficulty have negative impacts on time-based prospective memory and the ongoing task.
