最近的证据表明，双语对认知有积极的影响，包括痴呆症的后期发作。然而，单语者和双语者可能有不同的基线认知能力。我们提出的第一项研究检查双语对以后的生活认知控制儿童智力的影响。我们研究了853名参与者，首次测试于1947年（年龄=11岁），并于2008-2010年重新测试。双语者的表现明显好于从他们的基线认知能力预测，对一般智力和阅读的影响最大。我们的研究结果表明，双语对以后的生活认知有积极的影响，包括那些在成年后获得第二语言的人。
Recent evidence suggests a positive impact of bilingualism on cognition, including later onset of dementia. However, monolinguals and bilinguals might have different baseline cognitive ability. We present the first study examining the effect of bilingualism on later-life cognition controlling for childhood intelligence. We studied 853 participants, first tested in 1947 (age=11 years), and retested in 2008-2010. Bilinguals performed significantly better than predicted from their baseline cognitive abilities, with strongest effects on general intelligence and reading. Our results suggest a positive effect of bilingualism on later-life cognition, including in those who acquired their second language in adulthood.
