Formation of associations of colored and flavored food with induced sickness in five avian species 总被引:1,自引:0,他引:1
Domestic ducks, geese, pigeons, quail, and chickens were given colored, flavored, or colored and flavored food and then injected with lithium chloride. Each species showed learning of color and taste aversions. Flavor facilitated the formation of color aversions in ducks, geese, and pigeons but not in quail or chickens. Color interfered with the formation of flavor aversions in quail and chickens but not in the other three species. These findings indicate that all birds can probably associate both colored and flavored food with induced sickness and that colored food is more easily associated with induced sickness than is colored water. Moreover, these findings suggest that the capacity to associate colored and flavored food with induced sickness and the interaction between color and flavor in food vary between species. Birds, such as quail and chickens, that eat relatively tasteless food rely more on color than on flavor cues when forming learned food aversions. Birds that can select their food on the basis of taste, such as ducks and geese, rely more on flavor than on color when forming aversions to food. Birds, such as pigeons, that are initially raised on tasty food before switching to predominantly tasteless food show tendencies that are similar to those of ducks and geese. 相似文献

Martin Koci 《Modern Theology》2017,33(4):594-617
This article focuses on the idea of sacrifice in the work of the Czech phenomenologist Jan Pato?ka. It presents and examines this philosopher from a theological perspective against the background of the theological turn in contemporary philosophy. First, the article focuses on Pato?ka's reflections on the kenotic sacrifice, which he defines as the sacrifice for nothing. Second, Pato?ka's thought is put into dialog with Jean‐Luc Marion's phenomenological sketch of sacrifice embedded in his phenomenology of the gift. Although both Pato?ka and Marion share an interest in sacrifice, a phenomenon of high theological importance, only the latter enjoys reception on the part of theology. Yet, the article argues, on the basis of further inquiry into Pato?ka's writings, Pato?ka presents a complementary and alternative perspective that not only precedes the theological turn but also challenges and opens new ways for theology. The conclusion thus portrays a kenotic form of Christianity after the end of Christianity, drawn from Pato?ka, as a specific spiritual being‐in‐the‐world. 相似文献
