摘要：This study aimed to install an adequate response to the formation of functional classes of olfactory stimuli in three domestic dogs through training repeated and yoked reversals of simple discriminations in three phases: (1) with two stimuli (2) in pairs with two sets of stimuli, and (3) with four stimuli. The subjects learned the tasks in Phases 1 and 2, and one of them showed learning set of the task in Phase 1; but none responded in a way befitting the formation of functional classes. It is argued that the requirement to discriminating four stimuli in the same trial made the task too complex for the dogs, and a new study is suggested to deal with this difficulty.
