Research findings on the early perception of language-relevant speech sounds indicate that infants start out with sensitivities to sounds that they lose if these contrasts are not used in their language. This process is known as perceptual narrowing. Adults may have sensitivities to sounds that infants do not have, but this is not the main finding related to the early perception of language-relevant speech sounds. Similarly, adults do not lose their sensitivities to language-relevant speech sounds as part of the natural aging process. There are also differences between infants and adults with respect to their sensitivities to language-relevant speech sounds, making option C also incorrect.
