Is motor development really more advanced in Third World infants?
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.
