Does the selection of fox for their reactions to humans affect the decision-making during learning?

In foxes selectively bred by ICG SB RAS for domestication or aggressive behavior toward humans, the behavior was analyzed. We have used the foxes not selected for behavior features as a control. Control foxes also were bred on experimental farm of ICG SB RAS. The peculiarities of explorative activities of foxes toward new objects, introduced inside the domestic cage, as well as behavioral features during attenuation of focused attention on the object of food reinforcement are discussed in the paper. Domesticated foxes demonstrated less neofobia during experiments then aggressive and unselected ones. On the other hand, the explorative behavior of tame foxes was characterized by a greater variability of motor reactions compared to aggressive and unselected ones. In the test for attenuation of focused attention, tame foxes used a greater number of different actions compared to other studied groups. Fox cubs from the domesticated population, placed in a new environment for the first time, found various ways go through obstacles when following a person. Based on these results we discuss the peculiarities of the decision-making in foxes.
