【摘要】 目的:研究长春市7~15岁男女学生听觉简单反应时变化特点。方法:以长春市在籍中小学普通学生为研究对象,采取随机抽样方法,抽取中小学生7~15岁9个年龄段学生,其中每年龄段男女生各50人,共计900人,分别找出男女生在7~15岁期间听觉简单反映时的变化特点,并对男女学生其变化特点进行比较分析,找出两者之间的差异性和共性特点。结果:男生听觉简单反应时快速增长期为9~10岁和12~14岁;女生为8~9岁和11~13岁;男生第1次快速增长期增长幅度,男生为0.0489s,女生为0.0396s;第2次最快速增长期增长幅度,男生为0.0477s,女生为0.0407s;男女学生听觉简单反应速度快速增长期与负增长次数具有一致性;在7~15岁期间男女生听觉反应速度的快速增长期同有3次,负增长1次;男女学生听觉简单反应速度总体增长幅度具有一致性。结论:男女学生听觉简单反应速度快速增长期段具有明显不同,听觉简单反应速度快速增长期增长幅度具有一定差异,男女学生听觉简单反应速度快速增长期次数与负增长次数及总体增长幅度具有一致性。
【Abstract】 AIM:To study the changing features of auditory reaction in students of 7-15 years old in Changchun.METHODS:Common middle and primary students in Changchun were selected in this study with the method of random sampling.Totally 900 students at nine age segments of 7-15 years old were chosen,50 boys and 50 girls in each segment.Changing features of audition in the students aged 7-15 years old were found out respectively,and the results were analyzed for comparison,so as to find out the differences and similarities between boys and girls.RESULTS:Audition of boys developed fast from 9-10 and 12-14 years; and that of girls from 8-9 and 11-13. Increment of boys in the first developing period was 0.048 9 s,and 0.039 6 s for girls;that of boys in the second developing period was 0.047 7 s,and 0.040 7 s for girls.Audition of boys and girls had concordance between fast developing period and the times of negative growing up.There were three times of fast developing period and negative growing up once,and the developing range of students had concordance.CONCLUSION:Fast developing segments of audition of boys and girls show evident differences,as well as the developing range.Times of developing segments,negative grow up and general developing have concordance.
