Roles of experiments in modern psychology were discussed from five points of view. 1) Sophistication of common knowledge. 2) Test of working hypothesis. 3) Finding of new evidence. 4) Demonstration of a theory. 5) Educational tools. Finally, the author focused on role of animal experiment. To understand evolution of human mind, we have to compare our mind with that of other animals. To understand mind as function of the nervous system, we need a lot of knowledge obtained from animal experiment. Training of animal experiment is also good educational tool for psychology course.
