【摘要】 反应时测试广泛应用于医学、药学、卫生学、心理学、体质测试等基础研究和实际工作中。由于计算机选择反应时测试精度高、稳定性好,故在反应时测定中应用得越来越多。本文采用AT89C52和LED开发基于图案信号的选择反应时测试仪,其图案显示形式、时间等均为随机,较好地仿真了现实环境,赋予选择反应时以特定的职业特性,将有利于促进相关心理学与体育学等领域反应时的研究与应用。更多还原

【Abstract】 The tester of reaction time is widely used in fundamental and applied researches such as medicine,pharmacy,hygiene,psychology,physiology etc.Owning to its high precision and stability,computer tester is becoming more and more widespread in the RT test.In this paper,a new tester is developed which is based on figure signal by using AT89C52 and LED.Because the form,the time and the angle of the figure signal is at random,the tester can simulate the actual circumstances well.Endowed with the professional characteristics,the tester will help the relevant research and application well in psychology,physiology etc.更多还原
