S medslund , J. The acquisition of conservation of substance and weight in children. VI. Practice on continuous vs. discontinuous material in problem situations without external reinforcement. Scand. J. Psychol ., 1961, 2, 203–210. — Tests of conservation and addition/subtraction (+/—) with continuous and discontinuous material were given to 154 children between 4;9 and 7;3. With any material, +/ ‐ seems to be acquired before conservation of substance. Both +/‐ and conservation appear to be acquired earlier with discontinuous than with continuous material. The practice sessions involved no known external reinforcement. A number of acquisitions of conservation of substance were observed, and they were more frequent after practice on discontinuous than on continuous material.
