Precursors to language in very preterm infants and infants born small for gestational age
This is an on-going research project developed in close collaboration with pediatricians and endocrinologists at Hospital Sant Joan de Déu and Maternitat-Hospital Clínic. Speech perception abilities related to sound discrimination and categorization are explored at different points in time during the first year of life. Data from experimental paradigms and measures from standardized mental and lexical development scales (Bayley-III and MacArthur CDI) are obtained from the populations under study in order to explore the link between early abilities and later language and cognitive outcomes.
Lexical stress pattern preference and early word segmentation
This research explores infants’ knowledge of the prosodic, phonotactic and phonological properties of the native language and how this information can be used to find words in fluent speech. Possible differences between monolingual and bilingual participants are explored. The link between early word segmentation abilities and lexical development is currently under study with populations of full term and healthy preterm infants.
Cues to early language differentiation
The early recognition of the sound pattern of the native language and its differentiation from a non-familiar language is a critical starting point in language acquisition. The ability to differentiate languages is especially relevant in infants growing up in bilingual environments. Current studies explore the role of phoneme identity and phonotactics in this ability, using different pairs of languages and also dialects.
Phonological representation and word recognition in the second year of life
This research aims at exploring the phonetic detail represented in familiar words, especially focusing on vowels. Monolingual and bilingual participants are tested in a looking-while-listening paradigm to establish possible differences in their phonological representation of words, based on the properties of the phonological systems involved. Word recognition processes are currently under study in populations at risk for language disorders
Development of audiovisual speech perception
Aquesta líniaThis research aims at exploring infants early sensitivities for audio-visual speech correlations, and the mechanisms involved in these processes. We explore infants’ perception and integration of AV speech. We also focus on the speech perceptual narrowing processes that occur during the first year of life.
