Throughout their evolutionary history, humans have tried to domesticate a variety of wild terrestrial mammals, resulting in a limited number that has been successfully domesticated. Among these domesticated species, domestic goats () are a useful model species to study the effects of ontogenesis on the socio-cognitive abilities of domestic non-companion animals in their interactions with humans. To this end, the behavioral responses of two groups of goats with a different background of human socialization (high and low socialization) were compared in the impossible task test, an experimental paradigm aimed to study socio-cognitive skills and the tendency to interact with humans. Our results show that, when the task became impossible to solve, goats with a higher level of socialization interacted with the experimenter for a greater amount of time than subjects in the low socialization group, whereas the latter group exhibited increased door directed behavior. Overall, highly socialized goats made more social contact with humans compared to the other group in the impossible task paradigm.
在人类漫长的进化历史中，人们一直试图驯化各种野生陆地哺乳动物，但成功驯化的数量有限。在这些已驯化的物种中，家山羊是一种有用的模式物种，可用于研究个体发育对家养非伴侣动物与人类互动时社会认知能力的影响。为此，在旨在研究社会认知技能和与人类互动倾向的“不可能任务测试”中，比较了两组具有不同人类社会化背景（高社会化和低社会化）山羊的行为反应。我们的结果表明，当任务变得无法解决时，社会化程度较高的山羊与实验者互动的时间比低社会化组的山羊更长，而低社会化组的山羊表现出更多指向门的行为。总体而言，在“不可能任务”范式中，与另一组相比，高度社会化的山羊与人类的社交接触更多。
