324:, at first they are sensitive to all phonetic contrasts, including those that constitute phonemic contrasts not found in the language they are presently acquiring. Sensitivity to phonemic contrasts is important for word learning, and so infants will have to figure out which contrasts are important for their language and which are not. Some contrasts will confer a change in meaning between words, and others will not. Over the first year of life, infants become less sensitive to those contrasts not found in their native language. Studies have shown, however, that infants do not necessarily pay attention to phonemic differences when acquiring new lexical entries, e.g., 14-month-olds given the made-up labels "daw" and "taw" for new objects used these labels interchangeably to refer to the same object, even though they were capable of perceiving the phonetic difference between /d/ and /t/ and recognizing these as separate phonemes.

bilingual speakers, had made the contrast more difficult to detect. There was evidence, however, that by 12 months of age the bilingual infants were able to discriminate the sounds that were contrastive only in
Catalan. Thus, it appears that bilinguals who have a particular phonemic contrast in one of their languages but not in the other are, in fact, able to gain the ability to make the discrimination between the contrasting phonemes of the language that has the pair, but that age and especially input are major factors in determining ability to make the discrimination.

tailored to the language they hear as their input. In order to perceive a particular phonemic contrast, then, the pair must be contrastive in one's input. Generally, the earlier a language and/or phonemic contrast is learned, or is part of the input, the more sensitive a listener is to the phonemic boundaries of that pair and therefore better able to perceive the difference between the contrasting sounds. It is still possible, though, for late learners to acquire the ability to perceive contrasts that are not part of their first language.

one phoneme, /e/ ( is an allophone of /e/ in
Spanish). Spanish-Catalan bilinguals, then, need to be able to recognize the contrast to accommodate their Catalan language. In one study, Catalan monolingual infants appeared to accurately discriminate between the two vowels while Spanish monolingual infants did not appear to make discriminations. Spanish-Catalan bilingual infants also did not appear to discriminate between the two vowels at 8 months of age.

difficult task. For example, Dutch L2 English speakers were less capable of distinguishing between
English /æ/ and /ɛ/ than Dutch-English bilinguals. Native speakers of Japanese hear English /l/ and English /r/ as a single sound whereas for English speakers there is a significant difference, distinguishing ‘long’ from ‘wrong’ and ‘light’ from ‘right’.

Consider a study of

Researchers suggest that input plays a large role in this discrepancy; perhaps the infants had not yet received enough input to have gained the ability to make the discrimination, or perhaps their dual input, Spanish and
