- ItemLanguage acquisition in premature and full-term infants(NATL ACAD SCIENCES, 2010) Pena, Marcela; Pittaluga, Enrica; Mehler, JacquesWe tested healthy preterm (born near 28 +/- 2 weeks of gestational age) and full-term infants at various different ages. We compared the two populations on the development of a language acquisition landmark, namely, the ability to distinguish the native language from a rhythmically similar one. This ability is attained 4 months after birth in healthy full-term infants. We measured the induced gamma-band power associated with passive listening to (i) the infants' native language (Spanish), (ii) a rhythmically close language (Italian), and (iii) a rhythmically distant language (Japanese) as a marker of gains in language discrimination. Preterm and full-term infants were matched for neural maturation and duration of exposure to broadcast speech. We found that both full-term and preterm infants only display a response to native speech near 6 months after their term age. Neural maturation seems to constrain advances in speech discrimination at early stages of language acquisition.
- ItemPhonological acquisition in preterm infants(REVISTA DE NEUROLOGIA, 2010) Pena, Marcela; Pittaluga, Enrica; Farkas, ChamarritaIntroduction. The stock of phonemes used in the mother tongue is mostly acquired towards the end of the first year of life. Systematic exposure to speech begins, maintains and enhances the learning of native phonemes and lowers sensitivity to non-native ones. Speech deprival gives rise to serious problems in the infant's phonological development, yet little is known about the effects that premature exposure to speech can have on this learning. This study explores this issue by comparing the phonological discrimination of full-term and preterm infants at 12 months of age (corrected age in the preterm infants).
