  1. Range and Viranyi (2013):“Social Learning from humans or conspecifics : differences and similarities between dogs and wolves” Alexis Chamberlin

  2. Introduction • Lack of research into the what extent dogs’ characteristics originated from socio-cognitive skills of wolves. • Emotional Reactivity Hypothesis • Domestication lead to greater intraspecific skills with humans • Investigate • whether dogs and wolves with the same life experience differed in their ability to use a conspecific and a human in local enhancement task • Discern if the demonstrator hide food or not

  3. Subjects • 11 wolves, 14 dogs • Controls for life experience • Separated from mother 10 days after birth • Hand-raised in peer groups • Continuous access to humans the 1st 4 months of life • Obedience training: sit, down, roll over, leash walking • Socialized with 5 pet dogs to establish dominance relationship

  4. Procedure • Procedure • Demonstrator would walk in a line to each location to control for smell • Experimenter, demonstrator and hand-raisers refrained from interaction with the subject • Experimental conditions • Dog Demonstration, Dog Control, Human Demonstration, Human Control, Smell Control

  5. Discussion • Both wolves and the dogs benefit from a demonstration • Both groups clearly differentiated between the control and the reward conditions • Lack of latency indicates equal levels of motivation • Relied less on Olfactory cues as they age?

  6. Wolves used human demonstration more effectively than dog demonstration • The dogs paid more attention to the control human condition • Support for Domestication theory • Dogs have a priori interest in humans • Information Processing theory • Information Processing theory: humans act as buffer for dogs

  7. Wolves paid less attention to Dogs overall and special attention to humans • Demonstrator dogs might be less important since they aren’t conspecifics in the strictest sense • Wolves accepted ownership of the chick by the demonstrator dog • Wolves had very cooperative relationship with the human demonstrators • Wolves focused on different details of the demonstration • Different social structure than dogs Results suggest that dogs and wolves do not differ much in their ability to use information given by a human
