Productive vocabulary was measured every four months in 16- to 28-months-olds. Attainment of motor-milestones was also measured. An earlier age of sitting and walking predicted a higher intercept and a larger slope (growth) of productive vocabulary respectively, suggesting that attainment of walking propels linguistic development.
在 16 至 28 个月大的婴儿中,每四个月测量一次生产性词汇量。同时还测量了运动里程碑的获得情况。更早的坐姿和行走年龄分别预示着生产性词汇量的更高截距和更大斜率(增长),这表明行走的获得推动了语言的发展。
