Ten 2-year-old children with periventricular leukomalacia (PVL), a brain injury associated with prematurity, were evaluated using language samples. Five children scored less than 80 on cognitive testing (delayed). Five children with this disorder and normal cognitive scores were assessed at two ages, matched with the delayed group on CA and developmental level. The delayed group produced significantly fewer lexical tokens and spontaneous verbal utterances than did the CA-matched group. No significant differences were observed between the delayed group and either comparison group on other measures of lexicon, grammar, or communication. The data demonstrate a relation between cognitive abilities and measures of verbal productivity in children with PVL.
对10名患有脑室周围白质软化症（PVL）的2岁儿童进行了语言样本评估，PVL是一种与早产相关的脑损伤。5名儿童在认知测试中得分低于80分（发育迟缓）。对5名患有这种疾病且认知分数正常的儿童在两个年龄段进行了评估，在实际年龄（CA）和发育水平上与发育迟缓组相匹配。发育迟缓组产生的词汇标记和自发言语显著少于实际年龄匹配组。在词汇、语法或沟通的其他测量方面，发育迟缓组与任何一个对照组之间均未观察到显著差异。数据表明，PVL儿童的认知能力与言语产出测量之间存在关联。
