Infants initially hear all phonetic differences.
“An important discovery in the 1970s was that infants initially hear all these phonetic differences (Eimas, 1975; Eimas et al., 1971; Lasky et al., 1975; Werker and Lalonde, 1988).”
From Brain mechanisms in early language acquisition (2010) · cites this paper as Eimas, 1975
The paper reports that 2- and 3-month-old infants discriminate the /r–l/ contrast, and its Discussion proposes early sensitivity to “most, if not all” phonetic distinctions. That supports broad early sensitivity, but the paper does not establish as fact that infants initially hear all phonetic differences. (LLM, conf=0.84)
Experimental — accuracy not yet measuredInfants discriminate only between stimuli from different phonetic categories.
“Infants discriminated only between stimuli from different phonetic categories (12–14).”

The initial perceptual biases shown by infants in tests of categorical perception, as well as asymmetries in perception seen in infancy, produce a contouring of the perceptual space that is universal.
“The important point regarding development is that the initial perceptual biases shown by infants in tests of categorical perception (12–16), as well as asymmetries in perception seen in infancy (80, 81), produce a contouring of the perceptual space that is universal.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
