I wonder how is this cognitive development progress was measured, and I question the results of whichever study this refers to.
I acknowledge that "bilingual tots seem to outperform in cognitive development in the early years" seems both intuitive and logical.
This is a string of words that we'd expect to find together. We'd almost be offended if they weren't. Because both bilingualism and learning more things are better.
My concern over the reference to this research is that early cognitive development milestones are largely language acquisition milestones, and it has long been known that language acquisition is somewhat behind in bilingual tots. Rather than accelerated.
Generally, it is assumed that bilingual child development metrics will later catch up to those of their peer group.
Which is the inverse of "their monolingual classmates may catch up with them later".
Bilingual children aren't actually cognitively delayed, if only marginally on the face of their assessments, but rather they tend toward having a temporary delay in language acquisition due to to their bilingual environment. With any cognitive development disadvantage that this could theoretically cause essentially being non-risk.
However, I've never seen anything that indicates performant development due to bilingualism. Just the opposite, to a statistically relevant degree. Even if only marginally behind.
This is textbook information and part of the body of knowledge of language acquisition. It's not a vanguard research topic.
