This paper shows that Fechner's law of psychophysics is a special case of Stevens' power law with three parameters. Consequently, at least as good over-all fit to experimental data is always obtained, at the cost of one additional parameter, by using Stevens' power law involving an extra parameter added to the response variable.
本文表明，费希纳心理物理学定律是具有三个参数的史蒂文斯幂定律的一个特例。因此，通过使用涉及添加到响应变量的一个额外参数的史蒂文斯幂定律，总是能以增加一个参数为代价，获得至少同样好的对实验数据的总体拟合。
