Early receptive and productive language skills were examined for preterm low birthweight infants and full-term normal birthweight infants from middle-class homes. Nineteen preterm infants and 19 full-term infants were observed in a laboratory setting at the gestationally corrected age of 8 months. To avoid the frequent confound between prematurity and low socioeconomic status, mothers of the two groups of infants were matched on educational levels. Regression analyses were used to assess the relative influence of infant cognitive skills, infant sociability, infant birth status, and the mothers' language input as possible predictors of infant receptive language and vocal behavior. Receptive language skills were associated with higher cognitive performance, greater sociability, and preterm birth. Productive language skills were associated with higher cognitive performance. On the basis of this research, the prognosis for language development in preterm infants raised in middle-class homes appears to be excellent.
研究了来自中产阶级家庭的早产低体重婴儿和足月正常体重婴儿的早期接受性和表达性语言技能。在实验室环境中，对19名早产婴儿和19名足月婴儿在矫正胎龄8个月时进行了观察。为避免早产与低社会经济地位之间频繁出现的混淆因素，两组婴儿的母亲在教育水平上进行了匹配。采用回归分析来评估婴儿认知技能、婴儿社交能力、婴儿出生状况以及母亲的语言输入作为婴儿接受性语言和发声行为可能预测因素的相对影响。接受性语言技能与较高的认知表现、更强的社交能力和早产有关。表达性语言技能与较高的认知表现有关。基于这项研究，在中产阶级家庭中成长的早产婴儿的语言发展预后似乎很好。
