Research on the early development of fundamental cognitive and language capacities has focused almost exclusively on infants from middle-class families, excluding children living in poverty who may experience less cognitive stimulation in the first years of life. Ignoring such differences limits our ability to discover the potentially powerful contributions of environmental support to the ontogeny of cognitive and language abilities.
对基本认知和语言能力早期发展的研究几乎完全集中在中产阶级家庭的婴儿身上,而忽略了生活贫困的儿童,他们在生命的头几年可能体验到较少的认知刺激。忽略这些差异限制了我们发现环境支持对认知和语言能力个体发育的潜在强大贡献的能力。
