该假设被验证，不同的家庭在社会经济地位（SES）的儿童在他们的生产性词汇发展的速度不同，因为他们有不同的语言学习经验。在相隔10周的2个时间点记录了33名高SES和30名中等SES母亲及其2岁儿童之间的自然互动。这些相互作用的成绩单提供了基础，估计儿童的生产词汇之间的第一次和第二次访问和属性的母亲在第一次访问的讲话的增长。高社会经济地位的孩子比中等社会经济地位的孩子在他们的生产性词汇量的大小增长更多。作为SES的函数不同的母亲讲话的属性充分说明了这种差异。这些研究结果的影响机制，环境对儿童发展进行了讨论。
The hypothesis was tested that children whose families differ in socioeconomic status (SES) differ in their rates of productive vocabulary development because they have different language-learning experiences. Naturalistic interaction between 33 high-SES and 30 mid-SES mothers and their 2-year-old children was recorded at 2 time points 10 weeks apart. Transcripts of these interactions provided the basis for estimating the growth in children's productive vocabularies between the first and second visits and properties of maternal speech at the first visit. The high-SES children grew more than the mid-SES children in the size of their productive vocabularies. Properties of maternal speech that differed as a function of SES fully accounted for this difference. Implications of these findings for mechanisms of environmental influence on child development are discussed.
