Odor matching and odor memory in the rat
Physiology & Behavior, 1993To assess olfactory matching-to-sample learning, rats were exposed to two odors separated by a 1-s presentation of clean air. If, and only if, the odors were identical, a response produced a water reinforcer. High levels of performance were maintained over a series of 10 novel three-odor matching-to-sample problems on this conditional go/no-go ...

Cognitive factors in odor detection, odor discrimination, and odor identification tasks
Journal of Clinical and Experimental Neuropsychology, 2010The purpose of this study was to determine cognitive correlates of olfactory performance across three different tasks. A total of 170 men and women (30-87 years of age) were assessed in olfactory sensitivity, discrimination, and identification. Also, participants were tested in a range of cognitive tests covering executive functioning, semantic memory,

Using a limited set of odorants, previous studies have indicated that the ability of humans to discriminate and identify the components of olfactory mixtures is limited to approximately four. However, the ability to generalize these results may have been limited by specific neural or cognitive interactions among the particular odorants used.

Hedonics of Odors and Odor Descriptors
Journal of the Air Pollution Control Association, 1984The hedonic tone (pleasantness-unpleasantness) of an air pollution odor depends on its character and influences how annoying the odor may be. In the context of air pollution, both unpleasant and pleasant odors may become objectionable, while this is less likely for hedonically neutral odors.

The interaction between the vision of colors and odor determination is investigated through lexical analysis of experts' wine tasting comments. The analysis shows that the odors of a wine are, for the most part, represented by objects that have the color of the wine.

Journal of the American Pharmaceutical Association (Scientific ed.), 1950
Odors have been difficult to measure and classify with accuracy principally because no objective measuring method has been developed. The mechanism of olfaction is but little understood; several theories have been presented but none has been generally accepted.

Despite their many endeavors, sociologists have yet to systematically analyze the significance of olfactory phenomena in human interaction. In this essay, theauthors explore the social definitions of individuals, groups, and settings in terms of odors; and it is suggested that interpersonal and group relationships are at least partially contingent upon

Smell is the oldest sense of living species on our planet and has allowed communication between species from the beginning of life on earth. Odor has always fascinated mankind even in prehistorical times and the use of scented materials is documented since early history.

Odor Index: An Integration of Odor Parameters for Swine Slurry Odors
Transactions of the ASABE, 2010In the animal production industry, manure odors can be a potential nuisance to neighboring residents. A more suitable metric other than odor concentration and intensity is required to evaluate odor dispersion or to evaluate on-farm odor-reducing technologies.

On the Unpredictability of Odor
Angewandte Chemie International Edition, 2006AbstractThe relationship between molecular structure and odor has fascinated and puzzled chemists for more than a century. Despite a great deal of research on structure–odor relationships, prediction of the odor of a novel molecule remains a statistical exercise and models only provide a probability of the character, threshold, and intensity.
