Two experiments were designed to test predictions derived from a process model (Atwood & Polson, 1976) of the water-jug problem. The subjects' short-term memory load was reduced by presentation of figures regarding the results of possible moves and also by employing a paper-pencil test. Unlike the results reported by Atwood. Masson and Polson (1980), the memory condition greatly improved the subjects' performance in solving this problem and so did the presentation of subgoals. Possible implications of these results for the procss model were discussed.
