摘要
本研究目的在于考察常用编程环境下的多种计时与定时功能的时间精度,为独立编程控制心理学实验的相关人员提供实证依据。本研究分为两部分,第一部分实验验证计时器的精确性和稳定性,结果发现只有很少的计时函数可以提供高于或等于1毫秒计时精度;第二部分实验验证常见的定时功能:结果发现常用编程环境下的现成定时器控件均不能提供1毫秒精度的定时功能,只有多线程技术可实现1毫秒的定时精度。
The present study was intended to investigate the accuracy and stability of computer timing technology in psychological experiments which employed reaction time. as an indicator. Some suggestions might be valuable to psychological researchers and experiment programmers. There were two time testing experiments in the present study, In the first experiment, we focused on testing the accuracy and stability of six commonly used computer timing functions, The testing results showed that most timing functions were not able to provide millisecond accuracy. Only two types of timing function could provide Ims timing precision. In the second experiment, we focused on the different timer functional objects in different program languages. The results showed that only the multi-thread technology could perkxticaily trigger some functions in lms precision.
