在做出决定之前,人类会做出利弊权衡。例如一个人买车时肯定会以车的价值为参考来权衡支付得失。那么,动物界有类似的现象吗?动物会“三思而后行”吗?荷兰乌德勒支大学兽医系研究人员最近通过老鼠觅食实验发现,老鼠会在决定获取不同量的食物之前考虑该行动的付出。可见,正如文末约翰.萨拉蒙教授所言:无论与人与动物,做与能量使用有关的决定是生存的基础。 Before making a decision, humans will make trade-offs. For example, when a person buys a car, he will certainly weigh the gains and losses based on the value of the car. So, does the animal industry have similar phenomena? Does the animal think twice and think twice? Researchers at the Department of Veterinary Medicine at the University of Utrecht in the Netherlands have recently found that rats are considering eating before varying amounts of food. The action paid. It can be seen, as Professor John Salamon stated at the end of the article: Regardless of humans and animals, making decisions related to energy use is the basis for survival.
