Early Child Res Q. 2023 Mar 2;63:400-409. doi: 10.1016/j.ecresq.2023.01.009.
We explored if children's age moderated associations between their early life language experiences and their linguistic and cognitive skills. For 107 British children, aged 24 to 48 months, and their families, we collected 3 day-long audio-recordings of their naturalistic home environments ( = 15.06 h per day, = 1.87). Children's cognitive ability was assessed by parent-ratings and with a cognitive testing booklet that children completed at home. We found that the quantity, lexical diversity and vocabulary sophistication of adult speech were associated with children's linguistic and cognitive skills. However, these associations were not moderated by children's age. Our findings suggest that the influence of early life language experience is not differentiated at age 24 to 48 months, at least in the current sample.
我们探究了儿童年龄是否会调节其早期语言经历与其语言和认知技能之间的关联。对于107名年龄在24至48个月的英国儿童及其家庭，我们收集了他们自然主义家庭环境的3段为期一天的音频记录（每天平均时长15.06小时，标准差1.87）。儿童的认知能力通过家长评分以及儿童在家中完成的一本认知测试手册进行评估。我们发现成人言语的数量、词汇多样性和词汇复杂性与儿童的语言和认知技能相关。然而，这些关联并未受到儿童年龄的调节。我们的研究结果表明，至少在当前样本中，早期语言经历的影响在24至48个月时并无差异。
