Langer (2000) Not proved: Reply to Wynn. Child Development 71(6):1537-1539. Abstract Findings on whether young infants look longer at incorrect addition and subtraction have been inconsistent or, as in our study, negative. We hypothesize that imprecise ordinal calculating with very small numbers of objects develops in late infancy and precise calculating in early childhood.
