In this study, the authors investigated factors that affect bilingual children's vocabulary and story recall abilities in their 2 languages.
Participants included 191 Latino families and their children, who averaged 59 months of age. Data on parental characteristics and children's exposure to and usage of Spanish and English were collected. The authors assessed children's Spanish and English vocabulary and story recall abilities using subtests of the Woodcock-Muñoz Language Survey-Revised ( Woodcock, Muñoz-Sandoval, Ruef, & Alvarado, 2005).
Sizeable percentages of variation in children's English (R2 = .61) and Spanish (R2 = .55) vocabulary scores were explained by children's exposure to, and usage of, each language and maternal characteristics. Similarly, variations in children's story recall scores in English (R2 = .38) and Spanish (R2 = .19) were also explained by the factors considered in this investigation. However, the authors found that different sets of factors in each category affected children's vocabulary and story recall abilities in each language.
Children's exposure to and usage of their two languages as well as maternal characteristics play significant roles in bilingual individuals' language development. The results highlight the importance of gathering detailed sociolinguistic information about bilingual children when these children are involved in research and when they enter the educational system.
本研究旨在调查影响双语儿童两种语言词汇和故事回忆能力的因素。
参与者包括 191 个拉丁裔家庭及其子女，平均年龄为 59 个月。收集了有关父母特征以及儿童对西班牙语和英语的接触和使用的数据。作者使用 Woodcock-Muñoz 语言调查修订版（Woodcock、Muñoz-Sandoval、Ruef 和 Alvarado，2005）的子测验评估了儿童的西班牙语和英语词汇和故事回忆能力。
儿童对每种语言的接触和使用以及母亲的特征解释了儿童英语（R2=.61）和西班牙语（R2=.55）词汇得分的相当大比例的变化。同样，英语（R2=.38）和西班牙语（R2=.19）故事回忆得分的变化也可以用本研究中考虑的因素来解释。然而，作者发现，每个类别中的不同因素组影响了儿童在每种语言中的词汇和故事回忆能力。
儿童对两种语言的接触和使用以及母亲的特征在双语个体的语言发展中起着重要作用。研究结果强调了在双语儿童参与研究和进入教育系统时，收集有关其语言详细社会语言学信息的重要性。
