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

Is it true that infants acquire interrogative intonation patterns early in language development across languages?

Yes. Evidence from developmental psychoacoustics and language acquisition studies indicates that infants acquire sensitivity to and comprehension of interrogative intonation patterns very early in life across various linguistic backgrounds.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

The retrieved literature consistently supports the claim that infants develop an early sensitivity to and capacity for processing interrogative intonation or pitch-based categories across different languages. Multiple empirical studies confirm that infants differentiate question intonation from statements or assertions during the first year and a half of life. No papers refute the claim.
