Abstract
This paper proposes an experimental system named IST for facilitation of users' problem solving by providing image-schemas. First, it is ascertained based on a psychological experiment that image-schemas can promote user's analogical problem solving owing to their plasticity. The experimental result shows that image-schemas facilitating user's problem solving visualize the following two aspects abstractly; one is the objects and their relations appearing in the initial state of a target problem, and the other is the operators and their effects when applied. The IST system is constructed on the basis of the above result, taking the so-called radiation problem as an example.
