我们喂他们,我们让他们睡在我们的床上,我们和他们一起玩,我们甚至和他们说话。当然,我们爱他们。任何狗主人都会告诉你,他们的宠物有非凡的能力去理解周围的世界。他们是对的。科学家已经找到了很好的方法来找出人类最好的朋友的能力。在过去几年中,人类对小狗认知的理解中最大的进步之一就是使用MRI机器扫描狗脑。 MRI代表磁共振成像,这是一个持续描绘大脑的哪些部分通过什么外部刺激照亮的过程。正如任何小狗的父母所知,狗是高度可训练的。这种可训练的性质使得狗成为MRI机器的理想选择,不像鸟类或熊类等非驯养的野生动物。专门研究狗的认知,充分利用某种类型的MRI机器,fMRI(代表功能性MRI)来研究这些动物。这些机器检测血流量的变化,并用它来测量大脑活动。通过不断的研究,McGowan已经发现了很多关于动物认知和感受的知识。在2015年进行的一项研究中,McGowan发现人的存在导致狗的眼睛,耳朵和爪子的血流量增加,这意味着狗很兴奋。 McGowan还研究了狗被宠物时会发生什么。我们早就知道,对于人类来说,抚摸心爱的动物可以降低压力和焦虑的速度。嗯,事实证明狗也是如此。当人类宠物庇护狗15分钟或更长时间时,狗的心率会降低,整体而言会变得不那么焦虑。最近关于狗认知的另一项研究发现,我们心爱的伴侣动物可以分辨出我们情绪表达的差异。在使用fMRI机器进行的另一项研究中,科学家们发现,不仅狗可以区分快乐和悲伤的人脸,他们对这些人的反应也不同。

英国基尔大学生物学Essay代写:狗智力和情感

We feed them, we let them sleep in our beds, we play with them, we even talk to them. And of course, we love them. Any dog-owner will tell you that their pet has a remarkable capacity to understand the world around them. And they’re right. Scientists have figured out great ways to find out exactly what human’s best friend is capable of. Over the past several years, one of the biggest advances in our human understanding of doggie cognition has been the use of MRI machines to scan dog brains. MRI stands for magnetic resonance imaging, the process of taking an ongoing picture of what parts of the brain are lighting up through what external stimuli. Dogs, as any doggie parent knows, are highly trainable. This trainable nature makes dogs great candidates for MRI machines, unlike non-domesticated wild animals like birds or bears. Specializing in dog cognition, takes full advantage of a certain type of MRI machine, the fMRI (which stands for functional MRI), to study these animals. These machines detect changes in blood flow and use that to measure brain activity. Through ongoing research, McGowan has found out a lot about animal cognition and feelings. In a study done in 2015, McGowan found that a human’s presence leads to increased blood flow to a dog’s eyes, ears and paws, which means the dog is excited. McGowan also studied what happens to dogs when they are being petted. We’ve known for some time that for humans, petting a beloved animal can lead to lower rates of stress and anxiety. Well, it turns out the same is true for dogs. When humans pet shelter dogs for 15 minutes or more, the dog’s heart rate decreases and it becomes less anxious overall. Another recent study on dog cognition found that our beloved companion animals can tell the difference in our emotional expressions. In another study done with the fMRI machine, scientists found that not only can dogs tell the difference between happy and sad human faces, they also respond differently to them.
