在一些物种中观察到了第三方相互作用的Ehrs下降，并被认为是与战斗和配偶选择有关的决策过程中的重要信息来源。然而，人类在许多不同的情况下灵活地使用公开的信息，包括评估他人的利他主义倾向，这反过来又可能为他们选择最合适的合作伙伴提供信息。我们评估了狗，犬，是否能够辨别人类之间的慷慨与自私的食物分享互动，并调查哪些沟通线索（声音与手势）可能对他们更显着。重要的是，包括一个控制条件，以确定它是否实际上是个人之间的相互作用，而不是狗评估的演员的直接行动。我们发现狗能够偷听人类分享食物的互动，而声音交流对于传达人类的合作与不合作意图尤为重要。(C)2011年，动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Eavesdropping on third-party interactions has been observed in a number of species and is considered an important source of information in decision-making processes relating to fighting and 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 versus 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, and vocal communication was particularly important to convey the human's cooperative versus noncooperative intent.
