This research examined the role a global image of the result has in length seriation problem solving. The first experiment showed that when subjects could not take advantage of the figurai help provided by this image, the degree of task difficulty increased. The subjects did not succeed in changing their way of solving the problem (until 12). The control made in the second experiment helped partially the subjects (especially the oldest) to put their representation back in conformity with the task and to improve their performance.
