In this paper, we describe the characteristics of imagery phenomena in problem solving, develop a model for the process of forming and observing mental images in problem solving, and check the model against data obtained from subjects. Then, we describe the interaction between imaging and problem solving observed in our experiments, and discuss the use of our model to simulate it. We also discuss the relation between mental models and mental image briefly.

In this paper we discuss the role of imagery in understanding problems and the processes of using images to solve problems. On the basis of two experiments and computer simulation, we show how subjects, in solving a particular problem, form mental images to represent a changing physical state. By "running" and watching the mental Image they can draw qualitative conclusions about the situation, then derive a quantitative equation to solve the problem.
