Canine Generalization to Molecularly Similar Odors and Odor Mixtures
Abstract
The Naval Research Laboratory, in collaboration with the Naval Surface Warfare Center Indian Head EOD Technology Division and Florida International University performed research exploring the tendency for canines to generalize or discriminate similar odorants and odorant mixtures, referred to as the generalization-discrimination balance. The effects of molecular structure, mixture perception, and training on canine ability to generalize or discriminate between related target odors were studied. The effect of training was addressed by incrementally increasing the number of odorants as training continued. Controlled odor mimic permeation systems (COMPS) were used to provide consistent permeation rates across all odorants. Trial results indicated some tendency to increase generalization with increased training on multiple odorants, though only training on multiple functional groups increased generalization significantly. Best practice for detection canine training is to train each on a variety of materials and mixtures.
