Heuristics and representational change in two-move matchstick arithmetic tasks

and representational change by assessing whether the difficulty in solving insight problems is due to the search for proper heuristics that can be applied or whether it is due to requiring a change of the initial problem representation into a problem representation that includes the solution (cf. The role of heuristics in problem solving will now be examined, before covering the insight literature in relation to heuristics and to representational change. The goals of the current paper will then be outlined.
