Abstract
Este estudo objetivou ensinar um responder adequado a formação de classes funcionais de estímulos olfativos a três cães domésticos utilizando três fases de treino de reversões repetidas e combinadas de discriminações simples combinadas: (1) com dois estímulos; (2) em pares com dois conjuntos de estímulos e (3) com quatro estímulos. Os sujeitos aprenderam as tarefas nas Fases 1 e 2. Um dos sujeitos apresentou learning set da tarefa na Fase 1, mas nenhum apresentou responder condizente com a formação de classes. Discute-se que a exigência de discriminar quatro estímulos na mesma tentativa tornou a tarefa complexa demais para os cães e sugere-se um novo estudo para tratar com essa dificuldade.
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.
