The power of human language rests upon its intricate links to human cognition. By 3 months of age, listening to language supports infants' ability to form object categories, a building block of cognition. Moreover, infants display a systematic shift between 3 and 4 months - a shift from familiarity to novelty preferences - in their expression of this link between language and core cognitive processes. Here, we capitalize on this tightly-timed developmental shift in fullterm infants to assess (a) whether it also appears in preterm infants and (b) whether it reflects infants' maturational status or the duration of their postnatal experience. Healthy late preterm infants (N = 22) participated in an object categorization task while listening to language. Their performance, coupled with that of fullterm infants, reveals that this developmental shift is evident in preterm infants and unfolds on the same maturational timetable as in their fullterm counterparts.
人类语言的力量源于其与人类认知的复杂联系。到 3 个月大时，听语言支持婴儿形成物体类别，这是认知的基础。此外，婴儿在 3 到 4 个月之间表现出系统的转变——从熟悉到新奇偏好的转变——在语言和核心认知过程之间的这种联系上。在这里，我们利用足月婴儿这种时间紧迫的发展转变来评估（a）它是否也出现在早产儿中，以及（b）它是否反映了婴儿的成熟状态还是他们出生后经验的持续时间。健康的晚期早产儿（N=22）在听语言的同时参与了物体分类任务。他们的表现，以及足月婴儿的表现，表明这种发展转变在早产儿中是明显的，并与他们的足月对应物一样按照成熟时间表展开。
