在关于经常被引用的“3000万单词差距”的争论日益激烈的情况下，这项调查使用了来自美国社会经济领域的五个社区的语言数据，首次验证了哈特和里斯利（1995）的说法，即贫困儿童在生命早期听到的单词比中产阶级儿童少3000万个。这五项研究结合了民族志实地调查和对42名儿童（18-48个月）在日常生活中与家庭成员互动的纵向家庭观察。结果不支持哈特和里斯利的说法，揭示了每个社会经济阶层的词汇环境的实质性变化，并建议排除多个照顾者和旁观者谈话的言语环境的定义不成比例地低估了低收入儿童接触的单词数量。
Amid growing controversy about the oft-cited "30-million-word gap," this investigation uses language data from five American communities across the socioeconomic spectrum to test, for the first time, Hart and Risley's (1995) claim that poor children hear 30 million fewer words than their middle-class counterparts during the early years of life. The five studies combined ethnographic fieldwork with longitudinal home observations of 42 children (18-48 months) interacting with family members in everyday life contexts. Results do not support Hart and Risley's claim, reveal substantial variation in vocabulary environments within each socioeconomic stratum, and suggest that definitions of verbal environments that exclude multiple caregivers and bystander talk disproportionately underestimate the number of words to which low-income children are exposed.
