这项研究证明了双语能力与年龄相关的认知丧失之间的相关性.

Previous work has shown that bilingualism is associated with more effective controlled processing in children; the assumption is that the constant management of 2 competing languages enhances executive functions (E. 比亚韦斯托克,2001). 本研究试图确定这种双语优势是否在成年人中持续存在，以及双语是否会减弱衰老对老年人认知控制的负面影响. 有三个研究报告比较了单语和双语中老年人在西蒙任务中的表现. Bilingualism was associated with smaller Simon effect costs for both age groups; bilingual participants also responded more rapidly to conditions that placed greater demands on working memory. 在所有情况下，老年参与者的双语优势都更大. 似乎, 因此, 双语者能更有效地进行控制处理，双语有助于抵消某些执行过程中与年龄相关的损失.
