Development of Children's Ability to Judge Relative Numerosity.
McLaughlin, Judith A.
Journal of Experimental Child Psychology, v31 n1 p103-14 Feb 1981
Three- to 7-year-old children were trained through reinforcement to select the more or less numerous of two rows of squares. All children successfully judged relative numerosity when number covaried with length or density, but only concrete operational children were successful when numbers did not covary with other dimensions.
