Two languages in mind: Bilingualism as a tool to investigate language, cognition, and the brain
Current directions in psychological science, 2014
A series of discoveries in the last two decades has changed the way we think about bilingualism and its implications for language and cognition. One is that both languages are always active. The parallel activation of the two languages is thought to give rise to competition that imposes demands on the bilingual to control the language not in use to achieve fluency in the target language. The second is that there are consequences of bilingualism that affect the native as well as the second language. The native language changes in response to second language use. The third is that the consequences of bilingualism are not limited to language but appear to reflect a reorganization of brain networks that hold implications for the ways in which bilinguals negotiate cognitive competition more generally. The focus of recent research on bilingualism has been to understand the relation between these discoveries and the implications they hold for language, cognition, and the brain across the l...
Cognitive and Linguistic Processing in the Bilingual Mind
Current Directions in Psychological Science, 2010
The article reports research investigating the way bilingualism affects cognitive and linguistic performance across the life span. In general, bilingualism appears to have both benefits and costs. Regarding costs, bilinguals typically have lower formal language proficiency than monolinguals do; for example, they have smaller vocabularies and weaker access to lexical items. The benefits, however, are that bilinguals exhibit enhanced executive control in nonverbal tasks requiring conflict resolution, such as the Stroop and Simon tasks. These patterns and their consequences are illustrated and discussed. We also propose some suggestions regarding underlying mechanisms for these effects.

Bilingualism: Language and Cognition, 2014
The relation between bilingualism and cognition is informative about the connection between language and mind. From the perspective of language, the question is how bilingualism might help or hinder cognition – narrowly interpreted here as executive function. From the perspective of higher cognition, the question is what kinds of experiences improve executive function. Reported cognitive benefits from bilingualism range from none to substantial as a function of age, type of bilingualism (e.g., life-long balanced vs later-onset or infrequent use of the other language), syntactic relation between the two languages, socio-economic and immigrant status, task, and laboratory. To understand the variability and inconsistencies in results with bilingualism, I analyze concepts of executive function and cognitive reserve and examine the range of factors (such as active video game playing, education, musical training, and aerobic exercise) that are known to correlate with or to improve executi...
Bilingualism and cognition: A focus on mechanisms
Bilingualism: Language and Cognition, 2014
The goal of my keynote article, “Bilingualism and Cognition” (Valian, 2014), was to resolve the inconsistencies in effects of bilingualism on executive functions, whether the individuals were children, young adults, or old people. To summarize (and sharpen) my argument: 1.Especially in children and young adults, benefits of bilingualism for executive functions are not reliable. In old people, there are benefits for executive functions but contradictory results on delay of cognitive impairment, depending on whether studies are retrospective or prospective.2.All experiences that have benefits for executive functions and aging – and there are many – yield inconsistent effects. Bilingualism is not alone.3.Three reasons for inconsistencies in bilingualism and other experiences are: a.Executive function and cognitive reserve are broad cover terms for a variety of mechanisms, most of which are ill-understood. Because we mean different things by ‘executive function’ from one experiment to t...
Characterizing Bilingual Effects on Cognition: The Search for Meaningful Individual Differences
Brain Sciences
A debate over the past decade has focused on the so-called bilingual advantage—the idea that bilingual and multilingual individuals have enhanced domain-general executive functions, relative to monolinguals, due to competition-induced monitoring of both processing and representation from the task-irrelevant language(s). In this commentary, we consider a recent study by Pot, Keijzer, and de Bot (2018), which focused on the relationship between individual differences in language usage and performance on an executive function task among multilingual older adults. We discuss their approach and findings in light of a more general movement towards embracing complexity in this domain of research, including individuals’ sociocultural context and position in the lifespan. The field increasingly considers interactions between bilingualism/multilingualism and cognition, employing measures of language use well beyond the early dichotomous perspectives on language background. Moreover, new measu...
