经颅直流电刺激（tDCS）增强工作记忆任务的表现。然而，这种影响可能取决于工作记忆的特定方面的调制。因此，我们测试的假设，tDCS提高选择性注意力的背景下，斯滕贝格任务。受试者必须在对干扰刺激做出反应的同时保持记忆。探测器由记忆集中的一个项目和一个可能作为干扰物呈现的项目组成。只有当错误的选择是一个分心刺激时，TDCS才能显着改善反应时间。因此，结果支持的概念，tDCS对工作记忆的影响可能是介导的选择性注意的具体影响。(C)2012爱思唯尔爱尔兰有限公司保留所有权利。
Transcranial Direct Current Stimulation (tDCS) enhances performance on working memory tasks. However, such effects may be dependent on modulation of specific aspects of working memory. We therefore tested the hypothesis that tDCS improves selective attention in the context of a Sternberg task. Subjects had to maintain a memory set while responding to distracter stimuli. Probes consisted of one item from the memory set, and one item that could have been presented as a distracter. TDCS was found to improve reaction time significantly only when the incorrect choice had been a distracter stimulus. The results thus support the notion that tDCS effects on working memory might be mediated by a specific effect on selective attention. (C) 2012 Elsevier Ireland Ltd. All rights reserved.
