从工作记忆中过滤不相关信息的能力受损被认为是烦躁不安中相关信息的工作记忆能力下降的原因。本研究旨在探讨与训练相关的双n-back任务中工作记忆表现的提高是否会导致抑制功能的改善。训练效果在变化检测范式中监测，允许测量对工作记忆容量敏感的持续事件相关电位不对称和对无关信息的有效过滤。与积极对照组相比，训练组中焦虑的参与者在工作记忆方面表现出与训练相关的收益，同时工作记忆容量和过滤效率也有所提高。研究结果提供了重要的初步证据，表明通过加强注意力控制可以改善烦躁不安患者的行为表现和神经功能。
Impaired filtering of irrelevant information from working memory is thought to underlie reduced working memory capacity for relevant information in dysphoria. The current study investigated whether training-related gains in working memory performance on the adaptive dual n-back task could result in improved inhibitory function. Efficacy of training was monitored in a change detection paradigm allowing measurement of a sustained event-related potential asymmetry sensitive to working memory capacity and the efficient filtering of irrelevant information. Dysphoric participants in the training group showed training-related gains in working memory that were accompanied by gains in working memory capacity and filtering efficiency compared to an active control group. Results provide important initial evidence that behavioral performance and neural function in dysphoria can be improved by facilitating greater attentional control.
