Rapid learning of a phonemic discrimination in the first hours of life

Y. J. Wu, X. Hou, et al.

This fascinating study, conducted by Yan Jing Wu and colleagues, reveals how neonates quickly adapt their brain's neural mechanisms to discriminate phonemes, showcasing remarkable neuroplastic changes with just five hours of postnatal exposure to vowel sounds.

Abstract
This study investigated the neural mechanisms underlying neonates' ability to discriminate phonemes. Using functional near-infrared spectroscopy (fNIRS), researchers examined neuroplastic changes in neonates after 5 hours of postnatal exposure to natural and reversed vowels. The experimental group showed shorter haemodynamic response latencies for forward vs. backward vowels initially, and increased neural activity later, suggesting ultra-fast tuning to natural phonemes.
