不喜欢老鼠是什么?

我喜欢当一个科学研究多年来证明我所说的。老鼠很酷。好吧,这不是什么研究显示,但很有趣。

每当我面对客户询问带来一个小哺乳动物的智慧像仓鼠或沙鼠到他们的家里,在对话中我总是询问,“一只老鼠呢?”My interactions with pet rats have almost always been positive. They’re social critters that seem to enjoy contact with people, unlike most gerbils and hamsters that tend to tolerate us at best. Rats aren’t likely to bite. They are bigger and more robust than many pocket pets, while still being a manageable size that makes caring for them relatively easy. They also tend to live longer than hamsters and gerbils, which is a plus after you realize just how neat your rat is.

不喜欢什么?有些人就是不能克服他们的名声害虫,但事实上现代宠物老鼠不太可能携带的疾病可以影响人们比许多其他种类的动物。不能忍受白化病老鼠的起泡的红眼睛吗?“花哨”老鼠。有些人真正美丽的颜色和液体棕色眼睛。裸体的尾巴狂你吗?对不起,帮不了你。

回到学习。芝加哥大学的科学家想测试老鼠是否有能力的行为是为了另一个人(即受益。利他主义)。他们测试的存在被困cage-mate是否会带来希望帮助其他老鼠;在这种情况下,“免费”的老鼠是否会打开门抑制剂并设置其cage-mate免费。

答案是“是的。”Over time, the free rats learned to open the doors, after which both rats would run around excitedly. The researchers also tried to make sure that the free rats weren’t simply letting the trapped rats out because they wanted company. They ran another experiment where rats could set each other free, but the individuals remained separated afterwards. The free rats still helped out their trapped cage-mates. Rats were also just as likely to free their cage-mates as they were to open a restrainer that contained chocolate chips. And over 50 percent of the time they shared the chocolate, even though they could have eaten it all first and only then released their cage-mates.

老鼠另一个发现:女性比男性更有可能成为门开器,和学会这样做更快,引用作者的话,“是一致的建议,女性比男性更有共鸣。”Sorry guys.

研究人员甚至做了一个视频。看一看它。看着老鼠在行动是很多的乐趣,和评论是照明。
