Comparative study with infants differing in gestational age at birth, tested on a dual word segmentation and mapping task with natural language passages and visual cues to facilitate word extraction and word-referent association, two abilities linked to vocabulary building. Infants were tested at 9 months corrected age for gestation, with preterm infants having longer language experience than full-terms, but similar maturational age. Only full terms succeeded on the word mapping test. While visual cues were expected to facilitate word extraction, unsuccessful mapping is possibly related to the cognitive demands of the task, requiring simultaneous processes for the young learner. Differences in language development levels were also identified, suggesting a complex interplay of factors behind preterm infants’ early language learning skills.
