| Résumé : | Infants extract and learn regularities in their environment. How age impacts the outcome of this ‘statistical learning’ process, and what role is played by ex-utero experience and brain maturation, are open questions.Using an infant-controlled habituation paradigm in which 7- to 12-month-olds were familiarized with doublets of shapes, we examined their ability to differentiate between familiar and novel doublets, based on the transitional probabilities between shapes. We tested 54 full-term infants, and 39 very preterms matched for chronological age. The two groups had a comparable duration of exposure to ex-utero visual stimulations; preterms had lower levels of brain maturation.We used regression analyses to predict the duration of habituation and preference for novel doublets, based on age and prematurity. Although preterms took longer to habituate, both groups habituated faster as they got older. Critically, while learning was already evident in the youngest infants, with increasing age preference shifted from familiarity to novelty. Prematurity did not affect these preferences.Hence, although the speed of learning would depend on brain maturation, the latter would not affect the capacity to extract visual regularities nor the outcome of this learning. Rather, infants’ preference for novel sequences would depend on their ex-utero experience. |
