Recognition of odors and identification of sources.

The purpose of the present study was to investigate the accuracy of the memory for odors and for the location of odors. In Experiment 1, 5 unfamiliar odors were presented in each of 2 rooms. Twenty participants were instructed to remember only the odors (odor-only control group) and 20 were instructed to remember both the odors and the room where the odors were presented (odor place group). In Experiment 2, both the odor presentation room and the sex of the experimenters were manipulated to increase the uniqueness of the odor location. The results demonstrated that the memory for an odor is superior to the memory for the location of an odor. The results also indicated that the intention to learn the sources of an odor improves the memory for the source. These results are discussed in the context of the source monitoring framework.
