Abstract: With Model 504 eye tracker made in American applied science laboratory, two experiments were conducted to investigate children’s attention deployment strategies and developmental features of different age group children’s delay ability during self-imposed delay period. Delay time and eye movement features such as fixation duration, fixation number and saccade number were recorded while viewing symbolic presentation of the delay rewards to assess attentional processes. The results showed: （1）In each study, children paid more attention to color photograph than to black-and-white photograph of delay rewards and facilitate their self-imposed delay of gratification while viewing the color pictures;（2）Preschool children enhanced their delay ability when given “wish strategy” rather than “efficacy strategy” instruction; （3）The elder children spontaneously showed more attention to the pictures and had longer delay time than that of the young children

Key words: children, self-imposed delay of gratification, eye features
