This article is a secondary data analysis of the University of Kansas Language Acquisition Project, which intensively studied, on a regular basis, parent and child language from age 6 months to 30 months. The association between residential density and parent-child speech was examined. Parents in crowded homes speak in less complex, sophisticated ways with their children compared with parents in uncrowded homes, and this association is mediated by parental responsiveness. Parents in more crowded homes are less verbally responsive to their children. This in turn accounts for their simpler, less sophisticated speech to their children. This mediational pathway is evident with statistical controls for socioeconomic status. This model may help explain prior findings showing a link between residential crowding and delayed cognitive development.
本文是对堪萨斯大学语言习得项目的二次数据分析，该项目定期深入研究6个月至30个月大的亲子语言。研究了居住密度与亲子言语之间的关联。与居住不拥挤家庭的父母相比，居住拥挤家庭的父母与孩子说话的方式更不复杂、更不精细，这种关联由父母的反应性介导。居住更拥挤家庭的父母对孩子的言语反应更少。这反过来又导致他们与孩子说话更简单、更不精细。在对社会经济地位进行统计控制的情况下，这种中介路径很明显。该模型可能有助于解释先前显示居住拥挤与认知发展延迟之间存在联系的研究结果。
