描述来自双语家庭的典型发育儿童的英语和西班牙语成长轨迹，并将其与来自单一语言家庭的儿童的英语成长轨迹进行比较，以评估双语暴露对典型发育儿童的语言成长的影响。从30岁到60个月，每隔6个月评估一次有表现力的词汇量，单语者用英语，双语者用英语和西班牙语。通过父母的报告评估家庭中英语和西班牙语的使用情况。包括父母教育作为协变量的多水平模型显示，来自双语家庭的儿童在英语词汇增长方面落后于单语家庭的儿童6个月至1岁。滞后的大小与家庭使用英语的相对数量有关，但这种关系不是线性的。在英语使用率已经很高的家庭中，英语使用量的增加带来的好处最大。这些家庭也可能有一位以英语为母语的父母。双语儿童在英语方面表现出比在西班牙语方面更强的成长。在正常的英语语言发展中，双语儿童可能落后于单语儿童6个月到1岁。如果父母报告孩子在家庭语言方面也有技能，那么这种延迟可能不一定意味着临床上的延迟。较短的滞后时间与两个相关因素有关：更多的英语接触和来自英语母语者的更多接触。在家中及早接触西班牙语并不能保证掌握西班牙语。
To describe the trajectories of English and Spanish language growth in typically developing children from bilingual homes and compare those with the trajectories of English growth in children from monolingual homes, to assess effects of dual language exposure on language growth in typically developing children. Expressive vocabularies were assessed at 6-month intervals from age 30 to 60 months, in English for monolinguals and English and Spanish for bilinguals. Use of English and Spanish in the home was assessed via parental report. Multilevel modeling, including parent education as a covariate, revealed that children from bilingual homes lagged 6 months to 1 year behind monolingual children in English vocabulary growth. The size of the lag was related to the relative amount of English use in the home, but the relation was not linear. Increments in English use conferred the greatest benefit most among homes with already high levels of English use. These homes also were likely to have 1 parent who was a native English speaker. Bilingual children showed stronger growth in English than in Spanish. Bilingual children can lag 6 months to 1 year behind monolingual children in normal English language development. Such lags may not necessarily signify clinically relevant delay if parents report that children also have skills in the home language. Shorter lags are associated with 2 correlated factors: more English exposure and more exposure from native English speakers. Early exposure to Spanish in the home does not guarantee acquisition of Spanish.
