Abstract
Many researchers have historically shied away from psychological experiments with olfactory stimuli on account of their lack of ability to tackle the handling of odor substances. This article introduced various methods of presenting odor-stimuli in psychological experiments. From the highly skillful methods to control the chemical and physical properties of odorants by use of an expensive olfactometer to the simple method of arranging everyday-materials sold in the supermarket, explanations of various methods used in olfactory research were offered. Methods to carry out experiments using olfactometers, odor-jars, odor paper-strips, odor-bags, squeeze bottles and other tools, were described in detail.
