This study tested whether Bookstart – a program promoting book reading in infancy – continues to have an impact well into Kindergarten. We distinguished between children who were more or less challenging to read to in infancy (more or less temperamentally reactive). Eighty percent (n = 471) of a sample participating in a study when the children were one year old – about half involved in Bookstart – agreed to complete a home literacy survey when the children were, on average, 72.1 months. A smaller group (n = 318) also consented to collect tests concerning language and math at children's Kindergarten. The findings show that language development when they are about to start learning to read still profits from Bookstart. Especially the temperamentally most reactive 50 % shows benefits (d = 0.21). Bookstart also improved children's home literacy environment (longer book reading sessions), but this effect did not explain Bookstart's impact in Kindergarten.

这项研究测试了 Bookstart ——一个促进婴儿期阅读的项目——是否继续对幼儿园产生影响。我们区分了在婴儿期或多或少难以阅读的儿童（或多或少的气质反应）。80% ( n  = 471) 在孩子一岁时参与研究的样本（大约一半参与 Bookstart）同意在孩子平均 72.1 个月时完成家庭识字调查。一个较小的小组 ( n  = 318) 也同意在儿童幼儿园收集有关语言和数学的测试。研究结果表明，当他们即将开始学习阅读时，语言发展仍然受益于 Bookstart。尤其是气质上最活跃的 50% 显示出好处（d  = 0.21)。Bookstart 还改善了儿童的家庭识字环境（更长的读书时间），但这种效果并不能解释 Bookstart 对幼儿园的影响。
