Algorithmic solution of arithmetic problems and operands-answer associations in long-term memory

Many developmental models of arithmetic problem solving assume that any alg orithmic solution of a given problem results in an association of the two o perands and the answer in memory (Logan & Klapp, 1991; Siegler, 1996). In t his experiment, adults had to perform either an operation or a comparison o n the same pairs of two-digit numbers and then a recognition task. It is sh own that unlike comparisons, the algorithmic solution of operations impairs the recognition of operands in adults. Thus, the postulate of a necessary and automatic storage of operands-answer associations in memory when young children solve additions by algorithmic strategies needs to be qualified.
