Description
Summary:After 19 1st, 23 2nd, and 22 3rd graders acknowledged the equality of 2 lengths or areas, the equality was distorted by means of some common visual illusions. A child conserved length or area if he saw the illusion and, despite it, maintained that the lengths or areas were equal. The 1st graders had a significantly lower median number of conservations than the 2nd or 3rd graders (p < .001). The 2nd and 3rd graders were insignificantly different (p < .900). The transition from nonconservation to conservation occurred between the ages of 7 and 8.
