Objective To explore the impact of mental abacus calculation on children' s visual spatial attention by using event-related potential(ERP) technology.Methods The experiment of visual spatial attention in different spatial scaling cues was applied to 28 children with/without mental abacus calculation.Results The early visual spatial attention of children with mental abacus calculation was influenced by using visual space strategies,P1 components amplitudes increased and the latency decreased in occipital,occipital of left brain area was more obvious;visual spatial attention to the effective range of sizes suggested a different regulation in the prefrontal cortex: N1 amplitude of mental abacus calculation children was increased with the spatial scaling cues increased,but the P2 amplitude was reverse.The effect of spatial scaling cues to N1 amplitude was not significant to children without mental abacus calculation,P2 amplitude of the children without mental abacus calculation was increased with the spatial scaling cues increased.Conclusion The visual spatial attention could be influenced by abacus training of children.
