在工作记忆中保存信息对于认知是必不可少的,但消除不想要的想法也同样重要。在这里,我们使用大脑活动的多元模式分析来证明使用不同的策略,包括抑制特定的想法,用不同的想法代替一个想法,以及清除所有的想法,成功地操纵和去除工作记忆中的信息。这些策略由不同的大脑区域支持,并对允许新信息编码产生不同的结果。有多种方法可以清除一个人头脑中当前的想法。在这里,作者使用功能磁共振成像解码来确认使用不同的策略成功地清除思想,并表明这些策略具有不同的神经特征。
Holding information in working memory is essential for cognition, but removing unwanted thoughts is equally important. Here we use multivariate pattern analyses of brain activity to demonstrate the successful manipulation and removal of information from working memory using different strategies including suppressing a specific thought, replacing a thought with a different one, and clearing the mind of all thought. These strategies are supported by distinct brain regions and have differential consequences for allowing new information to be encoded. There are multiple methods of clearing one’s mind of current thoughts. Here the authors use fMRI decoding to confirm the successful clearing of minds using different strategies, and show that these strategies have distinct neural signatures.
