Sometimes the solution of a novel problem is achieved by transferring a strategy derived from a familiar situation which is similar to that problem, even though it concerns a different domain. This is the case of the so-called 'analogical problem-solving . Analogical problem-solving is a process of which artistic intuition, historical reconstruction, scientific discovery, and technological invention take advantage; it occurs in everyday thinking and in instruction where it allows to clarify concepts which are difficult to understand and to foster the development of creativity. It is an interesting 'crossroadéboth with intersections of some main theoretical constructs of psychology and with an overlapping of various mental functions. The book reports a series of experimental investigations whose aims were threefold. They were designed to assess empirically the influence exerted on analogical problem-solving by factors which research had neglected, to give a detailed picture of the processes underlying analogical problem-solving, and to test the psychological reality of some theoretical constructs.
