摘　　要：目的 探讨儿童青少年视觉简单反应时的变化规律及其影响因素。方法 采用自编反应时测定软件系统,对沈阳市7～21岁大、中、小学生1166名进行了视觉简单反应时测定。结果 7～21岁大、中、小学生视觉简单反应时随年龄增长而加快,平均、最慢、最快反应时、反应错漏率在大、中、小学生间差异有非常显著性(P<0.001),其中小学生反应时随年龄增长变化显著(P<0.05);平均反应时男性快于女性,在8～17岁年龄段(10岁、16岁除外)性别间差异有显著性(P<0.05)。结论 7～21岁大、中、小学生视觉简单反应时随年龄增长而加快,反应时男性快于女性,在某些年龄段性别间差异显著。Objective To study variation of simple visual reaction time of children and adolescents and its correlates. Methods A self - designed software was used to collect simple visual reaction time data from 1166 students at age 7-12 years in primary schools, secondary schools and colleges in Shenyang. Results Simple visual reaction time was getting shorter with age. The differences were significant in the average, shortest and longest simple visual reaction times, and in making error among students of primary schools, secondary schools and colleges(P < 0.01). Simple visual reaction time became more variable with age( P< 0.05). In almost every age group 8-17 years but 10 and 16 years, males responded significantly faster than males (P<0.05). Conclusions The older age is, the faster simple visual reaction time is among students aged 7-21 years, with much variation among primary school students. Males have faster reaction times than females; the male - female difference is obvious in some age groups.
