Abstract

Growing up with multiple siblings might negatively affect language development. This study examined the associations between birth order, sibling characteristics and parent-reported vocabulary size in 6163 Norwegian 8- to 36-month-old children (51.4% female). Results confirmed that birth order was negatively associated with vocabulary, yet exhibited a U-shaped pattern. A data-driven measure of “child-to-caregiver ratio” in the household was developed, in which old-enough siblings—females 1–3 years earlier than males—were considered caregivers for their younger siblings. This measure explained variance in vocabulary better than birth order, and indicates sex-differences in the age at which older siblings contribute to, rather than deplete, available resources. A child-to-caregiver ratio might better capture the interplay between language-learning resources and demands within households.

早期词汇习得:从出生顺序效应到儿童与照顾者比例
与多个兄弟姐妹一起长大可能会对语言发展产生负面影响。本研究调查了6163名8 - 36个月大的挪威儿童(51.4%为女性)出生顺序、兄弟姐妹特征和父母报告的词汇量之间的关系。结果证实,出生顺序与词汇量呈负相关,但呈现U形模式。研究人员开发了一种数据驱动的家庭“儿童-照顾者比率”测量方法,其中年龄足够大的兄弟姐妹(女性比男性早1-3岁)被认为是其弟弟妹妹的照顾者。这个方法比出生顺序更好地解释了词汇差异,并指出了年龄上的性别差异,即哥哥姐姐对可用资源的贡献,而不是消耗。儿童与看护人的比例可以更好地反映语言学习资源与家庭内部需求之间的相互作用。
