Inhibition training in wolves and dogs.

A theoretical model previously proposed by the first author hypothesizes that dogs (C. familiaris) should perform better than wolves (C. lupus) on training tasks in which (1) cues are arbitrarily selected by the experimenter, (2) reinforcement is administered by the experimenter, and (3) the to-be-learned behavior has no perceptible, functional connection with the reinforcement. To test this hypothesis, four Eastern wolf pups (C. l. lycaon) and four Alaskan Malamute pups (C. familiaris) were administered a passive inhibition task at seven weeks of age and an active inhibition test (leash training) at 11 weeks of age. Significant differences in the predicted direction were obtained for all task variables.
