中老年人计时尺手反应时测量的可靠性实验研究

Experimental Research on Reliability of Middle-and-Old Aged People's Hand Reaction Time with the Timing Ruler

本研究采用实验及统计分析法,对30名浙江师范大学45周岁以上的教师职工的手反应时进行测试。分别采用不同的重复测量次数进行多次测量,用多因素方差分析法对5次、7次、10次、15次的测量数据的可靠性进行统计分析,并从多维空间对各层面的测量误差的来源、误差成分以及它们对可靠性的影响进行了研究。结果表明:手反应时测验误差最主要的来源,来自受试者与各次测试成绩间的交互影响,手反应时重复测量的最佳次数为7次,取值的最好方法是剔除最大值和最小值后计算平均值,可靠性可达0.85。

With the experimental-statistical-analytical method, a test of hand reaction time is made on 30 peopleof Zhejiang Normal University who are over 45 years old. The test is repeated several times in different testing times. The reliability of the findings from the test of 5,7,10 and 15 times respectively is statistically analyzed with a multi-factor variance analysis method. A study is made from the angle of multi-dimensional levels to analyze the causes of errors and the influence of errors on reliability. The finding show the most important cause of the test errors of hand reaction time is from the inter-influence of the testees and their test results. The best number for repeated test is 7 times. Removing the highest and lowest results, the average reliability of the test is estimated to be 0.85.
