Concealing memories and emotions associated with a traumatic event seems to have negative effects on health. Re-enacting those events through writing is an opportunity to disclose such memories and emotions, and especially for emotion regulation. To study this, 57 university students were randomly assigned to one of two groups. They either completed an expressive writing or a neutral writing task. Real-time writing and psychophysiological data were recorded throughout the experiment to examine writing dynamics associated with emotion regulation and its psychophysiological correlates (electrodermal activity and electrocardiography measures). The results showed that the expressive group (EG) paused for longer than the control group (CG) denoting a positive and medium effect size ( η p 2 = .10 ) . Furthermore, during and after writing, the EG showed a higher low frequency/high frequency ratio than the CG, evidencing a positive and large effect size ( η p 2 = .22 ) . These real-time findings are interpreted as signs of emotion regulation happening during writing.

表现性写作的实时心理生理和写作相关性。

隐藏与创伤事件相关的记忆和情绪似乎对健康有负面影响。通过写作重演这些事件是一个机会，可以揭示这种记忆和情感，尤其是在情绪调节方面。为了研究这一点，将57名大学生随机分配到两组中的一组中。他们要么完成富有表现力的写作，要么完成中立的写作任务。在整个实验中记录了实时写作和心理生理数据，以检查与情绪调节及其心理生理相关性（皮肤电活动和心电图测量）相关的写作动态。结果表明，表达组（EG）的暂停时间比对照组（CG）更长，表示正效应大小和中等效应大小（ηp 2 = .10）。此外，在写作过程中和写作之后，与CG相比，EG的低频/高频比更高，证明了正的和大的效应大小（ηp 2 = .22）。这些实时发现被解释为在写作过程中发生情绪调节的迹象。
