Brain Plasticity: Lower brain plasticity in adults reduces the ease with which new speech sounds can be learned, especially if those sounds are not present in the first language. Reversible Effects: While the first language shapes the brain, foreign-language experience, especially during high-plasticity periods (infancy), can reverse the decline in discriminating non-native contrasts.
