早产儿有运动、知觉和认知发育延迟的风险。虽然研究表明早产儿在出生后的头几个月可能会表现出学习延迟，但这些延迟通常被诊断不足。本研究旨在纵向评估30名早产儿（PT）和23名足月儿（FT）在两种手段-目的问题解决任务中的行为表现和学习。婴儿在6、9、12、18和24个月大时进行了评估，要求他们拉毛巾或旋转转盘以获得远处物体。在整个研究中，PT婴儿比FT婴儿表现出更多的非目标导向行为和更少的目标导向行为，导致PT婴儿的成功率较低。PT婴儿表现出延迟出现的意向性（目标导向行为的患病率）相比，FT婴儿在这两个任务。行为表现的数量和变异性与不同年龄段的任务成功率显著相关。PT和FT婴儿之间的学习差异表明，手段-目的解决问题的任务可能是有用的早期检测学习延迟。识别与不同年龄段的学习和成功相关的行为，可用于指导旨在促进高危婴儿早期学习的干预措施。
Preterm infants are at risk for delays in motor, perceptual, and cognitive development. While research has shown preterm infants may exhibit learning delays in the first months of life, these delays are commonly under-diagnosed. The purpose of this study was to longitudinally evaluate behavioral performance and learning in two means-end problem-solving tasks for 30 infants born preterm (PT) and 23 born full-term (FT). Infants were assessed at 6, 9, 12, 18, and 24 months-old in tasks that required towel pulling or turntable rotation to obtain a distant object. PT infants performed more non–goal-directed and less goal-directed behavior than FT infants throughout the study, resulting in a lower success rate among PT infants. PT infants showed delayed emergence of intentionality (prevalence of goal-directed behaviors) compared to FT infants in both tasks. Amount and variability of behavioral performance significantly correlated with task success differentially across age. The learning differences documented between PT and FT infants suggest means-end problem-solving tasks may be useful for the early detection of learning delays. The identification of behaviors associated with learning and success across age may be used to guide interventions aimed at advancing early learning for infants at risk.
