    Analyzing pictures drawn by examinees is well-known in the field of clinical psychology and developmental psychol-ogy. As it is practiced in terms of analysis on psychological conditions or in terms of examination of the development of children's drawing, the graphic characteristics of the figures contained in examinees' pictures are not much regarded. Considering the further possibility on communicative com-petence through pictorial media, we can start with looking at the pictures drawn by the villagers in Lao P.D.R. and examine the graphic characteristics of their pictures. As the result of analysis, the pictures by villagers, which are not prepossessed with knowledge or theories of descriptive ge-ometry, show the different representations from descriptive geometry such as 3-surfaces representation, or 2-directions picture. Furthermore, while they show some resemblances to children's drawings, some figures are less distorted than children's ones.

    As a research on visualization ability of architectural space, the objective test (referred to as PIT) is developed, which identify the point and direction of the photo's sight in the floor plan. In the former research of authors, it is more difficult to visualize the exterior space than the inte-rior space. And it is more difficult to visualize the interior space with the atrium opened through two floors or more than the interior space enclosed in one floor. And to evalu-ate about the expression method and visualization of archi-tectural floor plan, PIT is applied to 631 students for 2 years after 1998. Principal results of the experiments are as fol-lows. 1) In the PIT, the rate of a correct answer becomes high by making a photograph into a color. 2) The rate of a correct answer becomes low by erasing furniture from photographs or drawings in the PIT. 3) Even when it added presentation by the expression method like a military projection and perpendicular information as shown in a sectional view, it doesn't become easy to visualize the exterior space, or to visualize the interior space open for two floors.

    The response time of the MCT was analyzed using the stereographic mental cutting test (SMCT) and the standard MCT. The principal results were as follows: (1) Total response time was shortened by about 30% as a consequence of using stereograms. (2) The correlation coefficient between response time and correct response rate indicate intermediate correlations in both tests. The results appear to suggest that the shorter the response time of a problem, the higher is its correct response rate. (3) By using stereograms depth cues were more easily recognized by subjects. Thus the process in recognizing 3-D shapes and location of cutting planes (Phase 1) was assisted and subjects im-proved their correct response rates and were shortened the re-sponse time required in the phase. (4) The problems in which errors occurred in the phase of Cutting the solid by the assumed cutting plane (Phase 2) or in the phase of judging the characteristic quantity (dimension) of the section (Phase 3), if necessary, did not show any improvements in their correct response rates even when using stereograms, although their response times required in the process of Phase 1 were shortened.
