采用贝利婴儿发展量表中的智力量表，对4个胎龄组56例婴儿进行了发育率和标准分的重复测量。出生后第一年的发病率可以通过一个生物学模型来预测，该模型假设同一概念年龄的婴儿发育平等。然而，基于生物学年龄的标准评分在最早的几个月内升高，表明子宫外寿命增加的短暂优势。对于最早产的组，生物学年龄为3至12个月的评分略高，但在组内是一致的，早产儿没有特别的加速。
Developmental rates and standard scores are examined for 56 infants in 4 gestational age groups by repeated measurements on the mental scale of the Bayley Scales of Infant Development. Rates across the first year of life can be predicted largely by a biological model that assumes equality of development for infants of the same conceptual age. However, standard scores based on biological age are elevated during the early months for the most premature groups, indicating a transient advantage of increased extrauterine life. Scores from 3 to 12 months' biological age are slightly higher for the most premature groups but are consistent within groups, with no special acceleration of the premature.
