A practical program edited by BASIC was used in this test. The test
included 7 indexes of fluid intelligence by using the method of talking between man and computer: speed of mental mathematic, digit-symbol, choice reaction time, counting visual number span, tracing reaction and recognition of meaningless figures. Through the principal component analysis and multiple stepwise regression techniques, the authors found out the mathematical model of the intelligence aging from 506 normal subjects and established a measuring system for the declined fluid intelligence and physiological age could be measured with the system. The correlation of the repetition of the test was 0.9528. This method was suitable for mental workers of 46-75 years old. The measured accuracy among the subjects of 50-70 years old was higher. The method was applied practically in clinical evaluation of the effects of traditional herbal medicines and Qigong on fluid intelligence with aging. Through the analysis of validity and reliability, it was proved that this method was suitable for geriatric research.
