Analysis of uniqueness and persistence of human scent

“The use of canines, Canis lupus var. familiaris, in law enforcement is widely accepted; however, there are few peer-reviewed studies confirming their accuracy and reliability. The use of detector dogs for human-scent lineups has been used in Europe, including Belgium, Denmark, Germany, Hungary, the Netherlands, Poland, and Russia, but has not gained widespread acceptance in the United States, mainly due to the lack of definitive studies demonstrating the reliability of this approach. Published results pertaining to the accuracy of canines used in human-scent lineups will be discussed later in the text.”

K-9 scent discrimination

“This website is a work in progress and is subject to change, but my intention is to first outline the ways in which knowledge about the relations between events is gained. Then explain what discrimination training really involves, what animals are learning during the course of discrimination training, and offer a user friendly, applied science plan for scent discrimination training.” E. Hale

This a a great website for scientific information relating to reinforcement, cause and effect relationships and scent discrimination.
