Motor and adaptive development were studied longitudinally at 4, 8, 12, and 18 mo. in Brazilian infants of low and middle socioeconomic status. No significant differences were found between these two groups. Gesell Developmental Quotients were similar to those found in American infants, which did not confirm precocious motor development in Brazilian infants.
对巴西社会经济地位低和中等的婴儿在4个月、8个月、12个月和18个月时进行了运动和适应性发育的纵向研究。这两组之间未发现显著差异。格塞尔发育商与美国婴儿的发育商相似,这并未证实巴西婴儿存在早熟的运动发育情况。
