Development will not proceed apace unless infants enjoy the kind of success in vocal communication that is enabled by cognitive, social, and motoric developments of one kind or another. 除非婴儿的认知能力、社会能力以及运动神经的发展已经使婴儿能够成功地体验到语言交流的快乐,否则语言的发展不会十分快速。
The evidence shows that infants enter extra uterine life with many strong perceptual biases and motoric dispositions already nudging them toward linguistically relevant patterns of stimulation. 这个证据说明,婴儿出生时就拥有强烈的认知上的偏好和运动神经上的预设,这使得它们对和语言相关的环境刺激产生了兴趣。
