工作记忆刷新训练改善抑郁倾向大学生情绪调节能力的HRV证据

根据流调中心用抑郁量表(CES-D)和贝克抑郁量表(BDI-Ⅱ-C)的得分情况招募健康被试20例,抑郁倾向被试40例,以自愿参加的分组方式将抑郁倾向被试分为工作记忆刷新训练组和对照组,每组20例。对训练组进行为期20天的工作记忆刷新训练,对照组不做处理。记录各组被试在前后测的刷新功能以及在情绪调节任务中量表的得分情况,并收集各组被试在5种实验条件下的心率变异性(HRV)的频域指标值,结果发现:前测时抑郁倾向个体的HF-HRV显著低于健康个体的平均水平。经过工作记忆训练,后测的抑郁倾向训练组在情绪调节任务中的HF-HRV水平有显著的提高,贴近健康对照组的水平,并与抑郁倾向对照组分离。研究表明,工作记忆刷新训练能够使抑郁倾向大学生的HRV活动更接近健康被试的HRV活动,表明抑郁倾向大学生的情绪调节能力得到了改善。

HRV evidence for the improvement of emotion regulation in university students with depression tendency by working memory training

Emotion regulation provides an effective way to understand and control our emotion. The lack of emotion regulation skill is viewed as one of the major causes of emotional problems, such as depression, anxiety disorder and others. Researchers have attempted to find an effective way to improve individuals’ emotion regulation ability. In recent years, a promising direction is working memory updating, which is an essential element in the central executive component of working memory. Some studies suggest that working memory updating plays a critical role in modulating the emotion regulation process and that working memory updating training can enhance emotion regulation ability.
