The role of children's verbal repetition of parents' utterances on vocabulary growth has been well documented (Masur, 1999). Nevertheless, few studies have analyzed adults' and children's spontaneous verbal repetition around the second birthday distinguishing between the types of repetition. We analyzed longitudinally Spanish-speaking parent-child dyads during spontaneous interaction at 21, 24 and 30 months. Linguistic level was measured using the Spanish version of the MacArthur CDI (López-Ornat et al., 2005). Children's and adults' repetitions are about 17% of the speech. Children repeated adults' utterances in a reduced manner whereas adults produced more extended repetitions. Adults' rate of repetition predicted children's linguistic level at 30 months. Children's rate of repetition did not predict linguistic level. These results suggest that parents adapt their speech to children's communicative abilities. Since children's rate of repetition did not predict linguistic level, we suggest that verbal imitation plays an indirect and complex role in communicative development.
儿童重复父母话语对词汇增长的作用已得到充分证明（Masur，1999）。然而，很少有研究分析过 2 岁左右成人和儿童自发的言语重复，并区分重复的类型。我们对 21、24 和 30 个月时进行自发互动的西班牙语母语的亲子对进行了纵向分析。语言水平使用西班牙语版 MacArthur CDI（López-Ornat 等人，2005）进行测量。儿童和成人的重复率约为言语的 17%。儿童以简化的方式重复成人的话语，而成人则会产生更长的重复。成人的重复率预测了儿童在 30 个月时的语言水平。儿童的重复率并不能预测语言水平。这些结果表明，父母会根据孩子的沟通能力调整自己的语言。由于儿童的重复率并不能预测语言水平，因此我们认为言语模仿在沟通发展中发挥着间接而复杂的作用。
