Abstract: The purpose of this study was to explore the developmental processand characteristics on the cognition of age. The results showed: 1. In the condition of showing the same amount of stimuli, the per-formances of preschoolers for recognition of fixed age-sequences were muchbetter than the performances for cognition of the relativity of age-seque-nce. the latter showed two obvious different stages between the pre-scho-oling period and formal schooling period. 2. The performancesfor cognition of the span of the age were muchbetter than for cognition of the born-sequences in preschoolers. 3. Cognition of the age for the future growing up in children showedtrends of divelopment from the short span of time to the long span oftime.
