This study explores the effects of training parents to administer focused stimulation intervention to teach specific target words to their toddlers with expressive vocabulary delays. Twenty-five mothers and their late-talking toddlers were randomly assigned to treatment and delayed-treatment (control) groups. Vocabulary targets were individually selected for each toddler based on the child's phonetic repertoire and parent report of vocabulary development. Following treatment, mothers' language input was slower, less complex, and more focused than mothers in the control group. Concomitantly, their children used more target words in naturalistic probes, used more words in free-play interaction, and were reported to have larger vocabularies overall as measured by parent report. In addition, the treatment had an effect on language development-children in the experimental group used more multiword combinations and early morphemes than children in the control group. The implications of these results are discussed with regard to the role of focused stimulation intervention for children with expressive vocabulary delays.
本研究探讨了培训家长对表达性词汇发育迟缓的幼儿实施集中刺激干预以教授特定目标词汇的效果。25位母亲及其学说话较晚的幼儿被随机分为治疗组和延迟治疗（对照）组。根据每个幼儿的语音储备和家长关于词汇发展的报告，为其分别选择词汇目标。治疗后，与对照组的母亲相比，治疗组母亲的语言输入速度较慢、复杂度较低且更具针对性。与此同时，她们的孩子在自然情境测试中使用了更多目标词汇，在自由玩耍互动中使用了更多词汇，并且据家长报告，总体词汇量更大。此外，该治疗对语言发展有影响——实验组的儿童比对照组的儿童使用了更多的多词组合和早期语素。文中讨论了这些结果对于集中刺激干预对表达性词汇发育迟缓儿童的作用的意义。
