Architectural Space Montage Technique was designed by the authors. The subject's mental schema is represented by spatial composition of miniatures on a 60 cm by 90 cm white plate. The scale for miniatures, such as furniture, people, trees, flowers and many kinds of standardized walls, is 1 to 50. In this experiment twenty-four kindergarten children made 40 models and drawings of the kindergarten. By analyzing each model, the drawing and the children, we clarified characteristics of many types of schema, such as the enclosure of space before structuralization, the birth of the structure, the organization of space.
