这篇教程旨在引导读者学习三种心理物理方法：调整法、极限法和恒定刺激法。本文阐述了如何用各种方法估计主观相等点和恰好可察觉差异。它还解释了在设计实验时可能遇到的陷阱。由于实验所采用的技术程序，结果可能会受到一些偏差效应的影响。人们应该知道这些影响可能发生在哪里。
This tutorial article aims to guide the reader to learn about three types of psychophysical methods: the method of adjustment, the method of limits and the method of constant stimuli. The article explains how to estimate the point of subjective equality and the just noticeable difference with each method. It also explains about pitfalls that one may encounter when designing experiments. Results could be distorted by some bias effects that are due to technical procedures adopted for experiments. One should know where these effects are likely to occur.
