What is it about a dog&39;s gaze that makes it so charming? A new study by Japanese scientist Miho Nagasawa seems to have found the answer, and it has to do with something called the cuddle(爱抚)chemical.
The cuddle chemical has another, more scientific name: oxytocin. Oxytocin is a substance in the blood that encourages bonding. Levels of oxytocin increase, for example, when a mother feeds her newborn baby. According to Nagasawa&39;s study, the same is true when we look deeply into the eyes of a dog.
The results of this study can tell us a lot about the history of the bond between humans and dogs. It all started somewhere tens of thousands of years ago. Scientists believe that wolves used to follow humans who were hunting large animals. The wolves would eat the food left behind by the humans.
Humans realized that they could use the wolves to help with the hunt, and eventually both species began to work together toward survival.
Over time, the wolves that interacted with the humans began to change. They became more loyal to their human partners. The wolves and humans started to depend on each other and bond with each other. These changes are what caused some of the wolves to turn into what we now know as dogs, a new specie^ evolved to better survive in their environment.
This process depended a great deal on the bond humans formed with them. And according to Nagasawa&39;s study, this bond was formed with the help of oxytocin, the cuddle chemical.

Tom was one of the brightest boys in the year, with supportive parents. But when he was 15 he suddenly stopped trying. He left school at 16 with only two scores for secondary school subjects. One of the reasons that made it cool for him not to care was the power of his peer (同龄人) group. The lack of right male (男性的) role models in many of their lives - at home and particularly in the school environment (环境)-means that their peers are the only people they have to judge themselves against. They don't see men succeeding in society so it doesn't occur to them that they could make something of themselves. Without male teachers as a role model, the effect of peer actions and street culture (文化) is all- powerful. Boys want to be part of a club. However, schools can provide the environment for change, and provide the right role models for them. Teachers need to be trained to stop that but not in front of a child's peers. You have to do it one to one, because that is when you see the real child. It's pointless sending a child home if he or she has done wrong. They see it as a welcome day off to watch television or play computer games. Instead, schools should have a special unit where a child who has done wrong goes for the day and gets advice about his problems - somewhere he can work away from his peers and go home after the other children. |
