Social-transmission of food preference is a robust behavioral phenomenon in rodents and other species, but less work has evaluated this phenomenon in broader taxa and to what degree social-transmission can occur between species. Here we show that over the span of three experiments that consisted of a human-dog, a dog-dog, and a replication study of a dog-dog demonstrator-observer test, we did not observe successful social transmission of food preferences across all three experiments. For our first experiment, we investigated whether pet dogs acquire food preference from their owners using a two-bowl preference test. The results suggested that our dogs did not acquire a preference for the flavor consumed by their owners. This then led us to investigate whether this failure was the result of an inter-species failure, so we replicated the experiment using two familiar dogs as the demonstrator and observer. The results for Experiment Two also suggested that our participant dogs do not acquire food preference from a canine demonstrator. A third experiment attempted a direct replication of the Lupfer-Johnson and Ross (2007) that found dog-dog transmission of food preferences. Our results again indicated that our participant dogs did not acquire food preference from demonstrators. Over the span of three experiments, our results did not show clear canine food preferences for the food consumed by a demonstrator (human or dog).

评估和重新评估家犬食物偏好的种内和种间社会传播

食物偏好的社会传播在啮齿动物和其他物种中是一种强烈的行为现象,但很少有工作在更广泛的分类群中评估这种现象,以及在物种之间发生社会传播的程度。在这里,我们展示了在由人-狗、狗-狗和狗-狗示范-观察者测试的复制研究组成的三个实验的跨度中,我们没有观察到所有三个食物偏好的成功社会传递实验。在我们的第一个实验中,我们使用两碗偏好测试调查了宠物狗是否从主人那里获得了食物偏好。结果表明,我们的狗没有对主人食用的味道产生偏好。这导致我们调查这次失败是否是种间失败的结果,所以我们用两只熟悉的狗作为演示者和观察者重复了这个实验。实验二的结果还表明,我们的参与者狗不会从犬类示范者那里获得食物偏好。第三个实验试图直接复制 Lupfer-Johnson 和 Ross (2007) 发现的食物偏好的狗-狗传播。我们的结果再次表明,我们的参与者狗没有从示威者那里获得食物偏好。在三个实验的跨度中,我们的结果没有显示出对演示者(人类或狗)食用的食物的明确犬类食物偏好。第三个实验试图直接复制 Lupfer-Johnson 和 Ross (2007) 发现的食物偏好的狗-狗传播。我们的结果再次表明,我们的参与者狗没有从示威者那里获得食物偏好。在三个实验的跨度中,我们的结果没有显示出对演示者(人类或狗)食用的食物的明确犬类食物偏好。第三个实验试图直接复制 Lupfer-Johnson 和 Ross (2007) 发现的食物偏好的狗-狗传播。我们的结果再次表明,我们的参与者狗没有从示威者那里获得食物偏好。在三个实验的跨度中,我们的结果没有显示出对演示者(人类或狗)食用的食物的明确犬类食物偏好。
