Abstract
We have been studying on the Computerized Kohs Block Design TEST (CKBD-TEST) for the evaluation of mental capability of the severely physically disabled who don't have enough linguistic skill to write and speak. A developed CKBD-TEST in the first stage of our studies has 24 types of surfaces which are obtained by the rotation of a block. From the result of clinical testing, there are some differences in difficulties between CKBD-TEST and general KBD-TEST. In this paper, a newly developed CKBD-TEST with rotation function is described. The result of clinical testing of the new CKBD-TEST reveals that these difficulties might be caused by the difference of testing procedures between CKBD-TEST and general KBD-TEST.
