RESUMO
Objective:To investigate gender differences in the attentional network in 5-year-old children.Methods:A totally of 70 healthy children [31 girls,(62.5 ± 2.6 months old;39 boys,(63.3 ± 2.8) months old] from the top class of kindergarten were enrolled in the study.A modified version of the Attention Network Test (ANT) was used to assess the attentional networks (alerting,orienting,and executive control).Results:The mean rate of accuracy was higher than 90％.A significant gender difference was found in the alerting network,boys scored higher than girls [(139 ± 54) ms vs.(109 ± 49) ms,P ＜ 0.05].No gender difference was found in the orienting or executive control networks (P ＞ 0.05).Conclusion:It suggests that 5-year-old children are fully capable of completing the attentional networks test,and the 5-year-old boy's alert function may be stronger than that of girls.
