摘要
以 4个实验 ,用图示法对键盘的时间精度作了比较分析。实验 1表明PES心理实验系统反应键和键盘都有良好的时间精度。实验 2表明键盘的时间精度具有很大的个体差异 ,范围从 1— 2毫秒到 40多毫秒 ,其中PS2的键盘普遍不理想。实验 3表明键盘的时间精度不受转接器和计算机主频的影响。实验 4使用了 3名操作者 ,证实了这种方法的效果基本不受操作者个体差异的影响。研究演示了图示法在计算机控制的心理学实验中确定仪器的时间精度的作用 ,提示了实验中需要针对具体的实验条件判断时间精度是否符合实验要求 ,来确定是否选用特殊的反应键或者选择何种键盘作为反应的方式。
A graphical analysis method (Myors, 1998) was used in 4 experiments. Experiment 1 demonstrated that the keypad of PES psychological experiment system had good t iming accuracy. Experiment 2 showed that the timing accuracy of different keyboa rds varied from 1 to about 40 msec. Those PS2 keyboards had poor performance, es pecially. Experiment 3 demonstrated that the PS2 to Normal and Normal to PS2 converter and the main processor frequency didn't affect keyboard timing accura cy. In experiment 4,3 operators were used and demonstrated that individual's dif ference didn't affect the power of this method. This study demonstrated the use of graphical analysis of timing accuracy, showed that in specific experiment, ti ming accuracy should be checked, in order to decide which kind of keyboard or ke ypad should be used, according to the timing accuracy of the experiment design. A small software named KBTST was provided for the timing accuracy checking.
