Abstract: This paper described the process of attaining the insight required to solve the Mutilated Chickboard (MC) problem,The results of the experiment showed that attaining insight requires discovering a correct problem representation,the parity space, In order to find the space,subjects have to change representation from the space of all possible coverings to the meta-level space of possible problem spaces for the MC problem. To find an appropriate representation, the subjects have to obtain strong constraints that guide search and make it highly selective. We also found that subjects were not always simply perceptually driven, Processing driven by concepts were higher transferable than by perception.

Key words: problem representation, problem space, search constraint
