the claim

Speaking two languages improves executive function in the brain.

the verdict
CONTESTED PARTIAL
Recorded sources
5 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that speaking two languages improves executive function in the brain?

Partly. Evidence on whether speaking two languages improves executive function is mixed and partial: a review and a Taiwanese student study report bilingual advantages in cognitive control, while a bi-dialect ERP study and a dialect-proficiency study found no such advantage or a disadvantage. No item settles the general claim across populations.
