Research Abstract	The purpose of this research is two-fold. Firstly, from a practical point of view, the development of a new computer program for an adaptive testing procedure was necessitated in order to measure the verbal ability more efficiently than the other existing procedures. Secondly, an experiment was designed in order to compare the efficiency of the adaptive testing procedure with that of the conventional testing procedure, analyze the effects of the feedback, investigate the relationship between the verbal ability and the response time, and evaluate the stability of the repeated measurements. With regard to the first purpose, a satisfactory computer program was created. This program automatically controlls the selection of test items during the process of administering the test so that the items administered to each subject should be appropriate in their difficulties. Furthermore, with regard to the second purpose, it was conculded that the results showed the superiority of the adaptive testing procedure over the conventional one in many respects.
