No evidence for a bilingual executive function advantage in the nationally representative ABCD study

It is shown, in a very large, demographically representative sample of 9- to 10-year-olds across the United States, that there is little evidence for a bilingual advantage for inhibitory control, attention and task switching, or cognitive flexibility, which are key aspects of executive function.

The impact of bilingualism on executive functions and working memory in young adults

The evidence presented here indicates that the bilingual advantage might indeed be caused by spurious uncontrolled factors rather than bilingualism per se, and is likely to affect working memory also.

Is Bilingualism Associated With Enhanced Executive Functioning in Adults? A Meta-Analytic Review

It is concluded that the available evidence does not provide systematic support for the widely held notion that bilingualism is associated with benefits in cognitive control functions in adults.

Different Features of Bilingualism in Relation to Executive Functioning

Results did not support any beneficial effects related to improve processing costs in executive functioning and future studies exploring the potential long-term term effects of bilingualism would benefit from identifying tests of cognitive control with greater ecological validity and include other measures of cognitive functioning.

The bilingualism wars: Is the bilingual advantage out of (executive) control?

Abstract Whether bilingualism has an effect on the executive function of non-verbal representations is probably one of the most controversial issues in cognitive psychology and cognitive

Does the Bilingual Advantage in Cognitive Control Exist and If So, What Are Its Modulating Factors? A Systematic Review

To conclude, there is some evidence for a bilingual advantage in cognitive control; however, if significant progress is to be made, better study designs, bigger data, and more longitudinal studies are needed.

Investigating the relationship between bilingualism, cognitive control, and mind wandering

ABSTRACT Some research has suggested that bilingualism produces cognitive control advantages, although it has recently been shown that reported advantages are influenced by a publication bias. If the

No evidence for bilingual cognitive advantages: A test of four hypotheses.

The authors suggest that bilingual benefits are not as broad and as robust as has been previously claimed and that earlier effects were possibly due to task-specific effects in selective and often small samples.

Are bilingual advantages dependent upon specific tasks or specific bilingual experiences?

Paap and Greenberg concluded that there is no coherent evidence for bilingual advantages in executive processing. More optimistic researchers believe that the advantages may be restricted to certain

Are there bilingual advantages on nonlinguistic interference tasks? Implications for the plasticity of executive control processes

It is suggested that bilinguals do enjoy a more widespread cognitive advantage that is likely observable on a variety of cognitive assessment tools but that is most often not apparent on traditional assays of nonlinguistic inhibitory control processes.

The Brain Mechanisms Underlying the Cognitive Benefits of Bilingualism may be Extraordinarily Difficult to Discover

The hypothesis that coordinating two or more languages leads to an enhancement in executive functioning has been intensely studied for the past decade with very mixed results. The purpose of this

Bilingual advantages in executive functioning: problems in convergent validity, discriminant validity, and the identification of the theoretical constructs

A review of the existing literature suggests that bilingual advantages (or disadvantages) may reflect task-specific differences that are unlikely to generalize to important general differences in EF and assumed measures of executive functioning may also be threatened by a lack of discriminant validity.

There is no coherent evidence for a bilingual advantage in executive processing

Cognitive Advantage in Bilingualism

Looking at conference abstracts from 1999 to 2012 on the topic of bilingualism and executive control found studies with results fully supporting the bilingual-advantage theory were most likely to be published, followed by studies with mixed results.

Is there a bilingual advantage in the ANT task? Evidence from children

The results showed no bilingual advantage at all, given that the performance of the two groups in the task and the indices associated with the individual attention networks were highly similar and statistically indistinguishable.

The inhibitory advantage in bilingual children revisited: myth or reality?

Investigating inhibitory skills in a large sample of 252 monolingual and bilingual children who were carefully matched on a large number of indices concluded that bilingual children do not exhibit any specific advantage in simple inhibitory tasks as compared tomonolinguals.

Effects of script similarity on bilingual advantages in executive control are likely to be negligible or null

The entire case that orthographic overlap enhances EC is built on the three comparisons out of nine where lower similarity bilinguals were significantly slower in global RT compared to bilinguals with greater script similarity, which seriously challenges the plausibility of the conclusion that Orthographic overlap has modulated EC.
