A shift from language-general to language-specific sound discrimination abilities has been largely attested in different populations of infants during the second half of the first year of life; however, data are still scarce regarding bilingual populations. Previous research with 4-, 8- and 12-month-old Catalan-Spanish bilingual infants had…

We probed simultaneous French-Spanish bilinguals for the perception of Spanish lexical stress using three tasks, two short-term memory encoding tasks and a speeded lexical decision. In all three tasks, the performance of the group of simultaneous bilinguals was intermediate between that of native speakers of Spanish on the one hand and French late…

Toddlers' and preschoolers' knowledge of the phonological forms of words was tested in Spanish-learning, Catalan-learning, and bilingual children. These populations are of particular interest because of differences in the Spanish and Catalan vowel systems: Catalan has two vowels in a phonetic region where Spanish has only one. The proximity of the…

Examined capacity of 4-month olds to identify their maternal language (Catalan or Spanish) when phonologically similar languages are contrasted. Compared infants from monolingual and bilingual environments to analyze whether differences in linguistic background affect this behavioral response. Found that language discrimination is already possible…

Compared online processing of Catalan phonemic contrasts in Spanish-dominant and Catalan-dominant Catalan-Spanish bilingual undergraduate students. Results supported hypothesis that L1 (first language) shapes the perceptual system at early stages of development in such a way that it will determine the perception of nonnative phonemic contrasts,…

Examined the ability of bilingual college students from Catalonia, Spain to learn a new vowel contrast as indicated by classifying the vowel, discriminating two vowels, and judging its "category-goodness." Found a lack of behavioral plasticity and that early, extensive exposure to a second language was sufficient to attain the…

Previous studies have suggested that nonnative (L2) linguistic sounds are accommodated to native language (L1) phonemic categories. However, this conclusion may be compromised by the use of explicit discrimination tests. The present study provides an implicit measure of L2 phoneme discrimination in early bilinguals (Catalan and Spanish).…

Behavioral studies have shown that while young infants can discriminate many different phonetic contrasts, a shift from a language-general to a language-specific pattern of discrimination is found during the second semester of life, beginning earlier for vowels than for consonants. This age-related decline in sensitivity to perceive non-native…
