近年来，我们已经调查了欧亚松鸦食物共享可能依赖于欲望状态归因的可能性。女性对特定类型食物的欲望可以通过满足她来降低（特定饱腹感），并且食物分享范例可以用来测试男性的分享模式是否反映了女性当前的欲望。我们之前的研究结果表明，雄性会分享雌性当前想要的食物。在这里，我们考虑三个更简单的机制，可能会解释男性的行为：行为阅读，缺乏自我和他者的分化和行为规则。我们说明了我们已经如何解决这些问题，以及我们的食物共享模式如何进一步适应，以回答悬而未决的问题。食物分享范式可以灵活地应用于排除替代机制，这使得它成为研究松鸦和其他物种分享食物的欲望状态归因的有用工具。
In recent years, we have investigated the possibility that Eurasian jay food sharing might rely on desire-state attribution. The female's desire for a particular type of food can be decreased by sating her on it (specific satiety) and the food sharing paradigm can be used to test whether the male's sharing pattern reflects the female's current desire. Our previous findings show that the male shares the food that the female currently wants. Here, we consider 3 simpler mechanisms that might explain the male's behavior: behavior reading, lack of self-other differentiation and behavioral rules. We illustrate how we have already addressed these issues and how our food sharing paradigm can be further adapted to answer outstanding questions. The flexibility with which the food sharing paradigm can be applied to rule out alternative mechanisms makes it a useful tool to study desire-state attribution in jays and other species that share food.
