使用标准化语言测试和眼动追踪方法评估早产儿和足月儿的语言技能。将妊娠 ≤ 32 周出生的儿童 (n = 44) 在性别和社会经济状况上与足月儿童 (n = 44) 进行匹配并进行纵向研究。婴儿和幼儿发育贝利量表第三版 (BSID-III) 在 18 个月大时进行（根据适用情况对早产进行校正）。边听边看（LWL）任务同时呈现两张图片和一个听觉刺激，将孩子的注意力引导到一张图片上。眼球运动的模式反映了视觉处理和语言理解的效率。 PT 儿童在 18 至 24 个月期间接受 3 次 LWL 评估。 FT 儿童的评估年龄与 PT 匹配的实际年龄和校正年龄相对应。比较 BSID-III 和两种 LWL 测量的各组结果：准确性（注视目标的时间比例）和反应时间（将视线从干扰物转移到目标的延迟）。 PT 儿童的 BSID-III 分数低于 FT 儿童。在实际年龄的 LWL 测量中，PT 儿童的表现比 FT 儿童差，但校正年龄的表现相似。 18 个月时的准确度和反应时间校正了年龄移位的 PT-FT 组成员资格，作为 BSID-III 评分的重要预测因子。与校正年龄相比，PT 和 FT 的语言理解测量的表现和变化率相似。语言理解效率的个体差异是两组标准化语言评估分数的有力预测因素。
To assess language skills in preterm and full term children using a standardized language test and eye-tracking methods. Children born ≤32 weeks gestation (n = 44) were matched on sex and socioeconomic status to full term children (n = 44) and studied longitudinally. The Bayley Scales of Infant and Toddler Development- Third Edition (BSID-III) were administered at 18-months (corrected for prematurity as applicable). The Looking-While-Listening (LWL) task simultaneously presents two pictures and an auditory stimulus directing the child’s attention to one image. The pattern of eye movements reflects visual processing and the efficiency of language comprehension. PT children were evaluated on LWL three times between 18 and 24 months. FT children were evaluated at ages corresponding to chronological and corrected ages of their PT match. Results were compared between groups for the BSID-III and two LWL measures: accuracy (proportion of time looking at target) and reaction time (latency to shift gaze from distracter to target). PT children had lower BSID-III scores than FT children. PT children had poorer performance than FT children on LWL measures for chronological age but similar performance for corrected age. Accuracy and reaction time at 18 months corrected age displaced PT-FT group membership as significant predictors of BSID-III scores. Performance and rate of change on language comprehension measures were similar in PT and FT compared at corrected age. Individual variation in language comprehension efficiency was a robust predictor of scores on a standardized language assessment in both groups.
