The purposes of the study were to develop the Central Auditory Processing Test Battery (CAPTB). The six tests were chosen according to the definition made by American Speech-Language-Hearing Association in 2005. The test composition followed these principles: first, non-speech materials were adopted as the stimuli; second, the test was designed as a computer-assisted system, in which low level of effort was required of subjects to make responses. The subjects were 3rd graders with normal hearing, including 30 for pre-testing, 100 for formal testing and 31 for re-test and criteria validity test. The CAPTB included frequency discrimination, gap detection, pitch pattern recognition, duration pattern recognition, dichotic pitch, and lateralization tests. The main results were as follows: (1) The internal consistency reliability ranged from .83 to .94, and the test-retest correlation coefficient of test scores was between .41 and .88; (2) The expert validity, criterion-related validity, and constructed-related validity were found satisfactory. Further discussion was made on the basis of these findings. Suggestions for the application of the CAPTB and future researches were also addressed.
