Drug addiction has been associated with unsuccessful emotion regulation, which can be improved by working memory training (WMT) in healthy populations. This study aimed to assess the effect of WMT on emotion regulation in drug abstainers. We divided 40 male drug abstainers into two groups: (i) the training group (n=20) participated in a running memory task for 20 days, and (ii) the control group (n=20) did not participate in any training task. We assessed the emotion regulation questionnaire (ERQ) and frontal electroencephalographic (EEG) activity while viewing pictures (including neutral, positive, negative and drug-related contents) for all participants before and after the training. After WMT for 20 days, the training group adopted more spontaneous emotion regulation strategies compared with control group. The asymmetry scores of training group improved while viewing negative and drug-related pictures compared to pretest, which suggests that they converted from right-brain asymmetry to left-brain asymmetry. However, the control group declined both in the ERQ scores and the asymmetry scores. These results suggest that WMT improves the emotion regulation of drug abstainers.
药物成瘾与情绪调节失败有关，而工作记忆训练（WMT）可改善健康人群的情绪调节。本研究旨在评估 WMT 对戒毒者情绪调节的影响。我们将 40 名男性戒毒者分为两组：（i）训练组（n=20）参与为期 20 天的跑步记忆任务，（ii）对照组（n=20）不参与任何训练任务。我们评估了所有参与者在训练前后观看图片（包括中性、积极、消极和与药物相关的内容）时的情绪调节问卷（ERQ）和额部脑电图（EEG）活动。经过 20 天的 WMT 后，与对照组相比，训练组采用了更多自发的情绪调节策略。与前测相比，训练组在观看负面和与药物相关的图片时的不对称评分提高，这表明他们从右脑不对称转变为左脑不对称。然而，对照组在 ERQ 评分和不对称评分上都有所下降。这些结果表明，WMT 可改善戒毒者的情绪调节。
