Abstract
20-85yr old audit subjects (forming 4 groups) were tested for studying the age differences on problem solving of practical life. At the same time, the twenty questions problem experiment was carried out. The results showed: (1) Rating consistency was up to standard for two groups of experimenters; (2) The number of scheme in putting forward (N) on practical problem solving was more in the three younger groups than the old group. However, no age differences were found in score of efficiency of practical problem solving; (3) The educational level had obvious influence on N and H scores; (4) The percentage in using strategy for guessing the picture and how many times could the aim pictures be reached had very significant age differences; (5) The N score of problem solving of practical life was correlated with using strategy for guessing pictures and how many times could the aim picture be reached; (6) The results suggested, age differences on problem solving in practical life was smaller than in the laboratory.
