年龄3随访数据的样本34个幼儿诊断年龄在24和31个月之间的表达型特异性语言障碍（SLI-E）。在3岁时，晚说话者在所有语言指标上的得分均显着低于21名在年龄、SES和非语言能力方面相匹配的同龄人。在随访中，前晚说话者在表达性单字图片词汇测试（EOWPVT）和表达性语言量表上的得分在平均范围内，但在MLU和Scarborough（1990 a）IPSyn上的得分比年龄预期低1.5个SD。在随访时，在平均范围内表现的晚说话者的比例随着所使用的测量的函数而显著变化（EOWPVT：79%，Mallell：58%，MLU：35%，IPSyn：24%），这表明晚说话者在词汇发展和使用语言来定义，解释和描述方面取得了更快的进展，而不是在句法和形态发展方面。3岁的结果唯一显着的预测因子是摄入表达语言水平，与年龄水平相比，在摄入时表达语言更严重延迟的幼儿在3岁时的结果最差。
Age 3 follow-up data are presented for a sample of 34 toddlers diagnosed between the ages of 24 and 31 months with expressive type specific language impairment (SLI-E). At age 3, the late talkers scored significantly lower on all language measures than 21 comparison peers matched at intake on age, SES, and nonverbal ability. When seen at follow-up, the former late talkers scored in the average range on the Expressive One-Word Picture Vocabulary Test (EOWPVT) and on the Reynell Expressive Language Scale, but more than 1.5 SDs below age expectations in MLU and on Scarborough's (1990a) IPSyn. The proportion of late talkers performing in the average range at follow-up varied markedly as a function of measure used (EOWPVT: 79%, Reynell: 58%, MLU: 35%, and IPSyn: 24%), indicating that the late talkers made more rapid progress in lexical development and in the use of language to define, explain, and describe than they did in the areas of syntactic and morphological development. The only significant predictor of age 3 outcome was intake expressive language level, with toddlers who had been more severely delayed in expressive language at intake relative to age level having the worst outcomes at age 3.
