Graph. 9, No. 1, 89-98 (2005).} \itemab Summary: This paper aims to evaluate the Laotian visualization ability for the architectural space. PIT and MCT were applied to 176 Laotian students at the National University of Laos. The results were as follows: The spatial ability (MCT) of Laotian students is lower than that of Japanese students in the fundamental course at Osaka University. But the visualization ability (PIT) of Laotian students of the architectural course is not lower than that of Japanese students in the fundamental course of Osaka University. Furthermore it turned out that for both the above mentioned Laotian and Japanese students it is more difficult to visualize the exterior space than the interior. And for all students it is more difficult to visualize the space which is open over two floors than that enclosed within one floor. \itemrv{~} \itemcc{} \itemut{} \itemli{http://www.heldermann-verlag.de/jgg/jgg09/j9h1sitt.pdf} \end
