ART: "Social Eavesdropping in the Domestic Dog", Oct-2011
Social eavesdropping in the domestic dog 10.1016/j.anbehav.2011.02.029 : Animal Behaviour | ScienceDirect.com
Quote:
Eavesdropping on third-party interactions has been observed in a number of species, & is considered an important
source of information in decision-making processes relating to fighting & mate choice.
Human beings, however, use publicly available information flexibly in many different contexts including assessing
others’ altruistic tendencies, which may in turn inform their choice of the most appropriate cooperative partner.
We assessed whether dogs, Canis familiaris, were capable of discerning a generous versus selfish
food-sharing interaction between humans, and investigated which communicative cues (voice vs gestures)
may be more salient for them. Importantly, a control condition was included to ascertain whether it was in fact
the interaction between individuals, as opposed to the direct actions of the actors, that the dogs evaluated.
We found that the dogs were capable of eavesdropping on human food-sharing interactions, & vocal communication
was particularly important to convey the human’s cooperative versus non-cooperative intent.

there are also graphs of the dogs' gaze-time [generous vs selfish person], & their approach/avoid responses.
