Objective: To study the characteristic of children's Event-Related Potentials(ERP) by visual spatial attention to different spatial scaling cues.Methods: The cue-target experimental paradigm was adopted,and the attended range was cued by different circles.The subjects included fourteen health children.Results: The reaction time became shorter with the decrease of the cue scale,while P1 and N1 components amplitudes increased,P2 components amplitudes decreased.Conclusion: In the early stages of processing of spatial attention,children rely on the effectiveness of prompt mobilization of the brain resources;and the later stages of the brain requires additional resources.
