The hypothesis that managing two languages enhances general executive functioning is examined. More than 80% of the tests for bilingual advantages conducted after 2011 yield null results and those resulting in significant bilingual advantages tend to have small sample sizes. Some published studies reporting significant bilingual advantages arguably produce no group differences if more appropriate tests of the critical interaction or more appropriate baselines are used. Some positive findings… Expand
No evidence for a bilingual executive function advantage in the nationally representative ABCD study

  • Nature Human Behaviour

TLDR
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
TLDR
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. Expand

Is Bilingualism Associated With Enhanced Executive Functioning in Adults? A Meta-Analytic Review
TLDR
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. Expand
Different Features of Bilingualism in Relation to Executive Functioning
TLDR
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. Expand
Is there electrophysiological evidence for a bilingual advantage in neural processes related to executive functions?
TLDR
The existence of a bilingual advantage in neural processing related to executive functions remains uncertain and further studies are required, but the utility of investigating several ERPs that have been ignored by previous studies is highlighted. Expand
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 cognitiveExpand
Does bilingualism shape inhibitory control in the elderly
Abstract Bilingualism has been argued to benefit executive functioning. However, recent research suggests that this advantage may stem from uncontrolled factors or incorrectly matched samples. InExpand
Does the Bilingual Advantage in Cognitive Control Exist and If So, What Are Its Modulating Factors? A Systematic Review
TLDR
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. Expand
Age-related effect on language control and executive control in bilingual and monolingual speakers: Behavioral and electrophysiological evidence
TLDR
The overall purpose of the present research was to gain insights into the influence of bilingualism on executive functions, by exploring aging-related changes and suggesting that a bilingual advantage is only observed in language-based tasks. Expand

No evidence for bilingual cognitive advantages: A test of four hypotheses.
TLDR
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. Expand
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 certainExpand
Are there bilingual advantages on nonlinguistic interference tasks? Implications for the plasticity of executive control processes
TLDR
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. Expand
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 thisExpand
Bilingual advantages in executive functioning: problems in convergent validity, discriminant validity, and the identification of the theoretical constructs
TLDR
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. Expand
There is no coherent evidence for a bilingual advantage in executive processing
TLDR
A problem reconfirmed by the present study is that effects assumed to be indicators of a specific executive process in one task frequently do not predict individual differences in that same indicator on a related task, which undermines the interpretation that these are valid indicators of domain-general abilities. Expand
Cognitive Advantage in Bilingualism
TLDR
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. Expand
Is there a bilingual advantage in the ANT task? Evidence from children
TLDR
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. Expand
The inhibitory advantage in bilingual children revisited: myth or reality?
TLDR
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. Expand
Effects of script similarity on bilingual advantages in executive control are likely to be negligible or null
TLDR
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.
