一种用于心理测验伪随机数序列的产生方法

摘要

Objective To develop a method of generating pgeudo random number(PRN) applied in simulating signal of psychomotor vigilance task in psychology test. Methoda PRN series were generated by the random function of computer program and were transformed to an equilibration distribution PRN series based on the special arithmetic rule which suitable for the psychology test. The signal of psychomotor vigilance task would be controlled by the PRN series. Results The signal of psychomotor vigilance task controlled by the PRN series showed an equilibration distribution random sequence. Conclusion PRN series generated by the computer program shows an equilibration distribution PRN series which is suitable for the psychology test.%目的:设计一种伪随机数序列的产生方法,用于心理学实验中告警信号的模拟.方法:采用计算机软件Random函数产生随机数,按照不同实验的要求,按一定的规则进行变换,产生平均分布的随机数序列,用于控制视觉刺教信号随机顺序呈现或随机时间呈现的过程.结果:将此随机数序列作为刺激信号呈现的顺序,实现了刺激信号呈现平均分布的随机性要求.结论:通过Random函数和一定的规则变换产生的随机数序列,达到了平均分布随机数的要求,可以实现心理学实验的需求.
