The need of bilinguals to continuously control two languages during speech production may exert general effects on their attentional networks. To explore this issue we compared the performance of bilinguals and monolinguals in the attentional network task (ANT) developed by Fan et al. [Fan, J., McCandliss, B.D. Sommer, T., Raz, A., Posner, M.I. (2002).(More)
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 contrasts has(More)
Do nonselected lexical nodes activate their phonological information? Catalan-Spanish bilinguals were asked to name (a) pictures whose names are cognates in the 2 languages (words that are phonologically similar in the 2 languages) and (b) pictures whose names are noncognates in the 2 languages. If nonselected lexical nodes are phonologically encoded,(More)
This study examined the capacity of 4-month-old infants to identify their maternal language when phonologically similar languages are contrasted, using a visual orientation procedure with a reaction time measure. Infants from monolingual and bilingual environments were compared in order to analyze whether differences in linguistic background affect this(More)
Previous research by Dupoux et al. [J. Memory Lang. 36, 406-421 (1997)] has shown that French participants, as opposed to Spanish participants, have difficulties in distinguishing nonwords that differ only in the location of stress. Contrary to Spanish, French does not have contrastive stress, and French participants are "deaf" to stress contrasts. The(More)
The present investigation was devoted to unraveling the time-course and brain regions involved in speech segmentation, which is one of the first processes necessary for learning a new language in adults and infants. A specific brain electrical pattern resembling the N400 language component was identified as an indicator of speech segmentation of candidate(More)
Languages differ in the constitution of their phonemic repertoire and in the relative distinctiveness of phonemes within the repertoire. In the present study, we asked whether such differences constrain spoken-word recognition, via two word reconstruction experiments, in which listeners turned non-words into real words by changing single sounds. The(More)
The conventional view is that perceptual/cognitive development is an incremental process of acquisition. Several striking findings have revealed, however, that the sensitivity to non-native languages, faces, vocalizations, and music that is present early in life declines as infants acquire experience with native perceptual inputs. In the language domain,(More)
There is considerable debate about whether bilinguals can distinguish L2 phonemic contrasts as efficiently as first language speakers can. To test this issue, a group of highly proficient Spanish-dominant Catalan-Spanish bilinguals (who had been exposed to Catalan between the ages of 3 and 4, but who, previous to this age, had been exposed only to Spanish)(More)
This study used medium-term auditory repetition priming to investigate word-recognition processes. Highly fluent Catalan-Spanish bilinguals whose first language was either Catalan or Spanish were tested in a lexical decision task involving Catalan words and nonwords. Spanish-dominant individuals, but not Catalan-dominant individuals, exhibited repetition(More)
