Abstract: This experiment aims at investigating the development of spatial orientation of children in China.Experiment proceeded in situations, closely resembling playful activity, was divided into two parts: The first part was to search for toys "according to spatial impressions"; the second was to find toys "according to locations defined by verbal directions". The subjects were composed of 40 healthy Children aged 3—6, with 10 in each age group. Each child participated in both parts of the experiment.The following results were disclosed: (1) Children of 3 to 6 years old showed some age difference in discriminating directions. Children of the age-group 5 seemed to reveal a tendency showing tremendous progress in preception of direction.(2) The order of difficulty in discriminating different directions was: top, bottom, back, front, left, and right.(3) The age difference in discriminating directions and that in discriminating different directions were probably dependent on different ability to abstract and generalize, and on the level of differentiatial inhibition of the second signal system.
