The first year of life is punctuated by explosions of growth in motor and language abilities. This is not a coincidence. The notion of developmental cascades provides a conceptual framework for considering ways in which advances in one component of a developing system can exert far-reaching and lasting change in other domains. In this article, I review evidence for the cascading effects of early motor advances on the developing communication and language system and describe how variability in the timing of these advances may alter the nature of these effects.
生命的第一年以运动和语言能力的爆发式增长为特征。这并非巧合。发展级联的概念提供了一个概念框架,用于思考发展系统中一个组成部分的进步如何能够在其他领域产生深远而持久的变化。在本文中,我回顾了早期运动进步对发展中的交流和语言系统产生级联效应的证据,并描述了这些进步时间上的变异性如何可能改变这些效应的性质。
