Hopefully, some of these facts help you learn more about sleep and why it is a little more interesting than you might have thought before.【小题5】, so you can get to the bottom of the problem and regain your ability to sleep well.

Being able to tell human faces apart is a skill that almost every person has, although some are far better at it than others. But a new study out from the journal Scientific Reports says that this is not just a skill that humans possess. Even fish can do it.

Following up on research studying different species’ abilities to recognize human faces (sheep, dogs, cows, horses, and-birds have all been tried), the researchers from the University of Oxford and the University of Queensland decided to pick an animal that does not have an evolved neocortex, the part of the brain that processes sight and sounds, and does not have a close relationship with humans. That way, there would be no reason why these test subjects would have a past history of identifying human faces. So they picked the archerfish, a reef fish variety that shoots water into the air to knock its prey out of the sky. They used this adaptation to have the fish spray water at a face on a monitor hanging over their tanks for a reward. Most of the fish were able to pick out their learned face, even when colors were taken away or methods were used to make the face shapes unclear.

This study gives more backing to the hypothesis that differentiating between faces is not just a skill that big -brained organisms are born with. It is possible that a good portion of recognizing faces is learned over time. The development of the neocortex may contribute only to quickly process a large number of faces in varying situations. But more work needs to be conducted to find a deeper link to this possible learned behavior. The sample size of this study was very small—only eight fish were used altogether. Also, the faces displayed on the monitor were only white, female faces from a German database, shown in a frontal view, with no expressions. Other animal trials have shown that some species, like pigeons, respond more to differing angles and varied expressions.

Every parent wants their children to develop well. Sometimes it seems that a child’s game is empty entertainment and it would be better to replace it with something more useful. However, for a child, play is the main way of interacting with the world, mastering new knowledge and skills.

The game forms a unique model of the world, redesigned in accordance with the needs and capabilities of the children. It reflects the real world and helps to master it. That is why it is so important to choose the right toys for your children.

For a child, any game is the same productive activity as work for an adult. And if the result of adult work is the produced “product”, for children, the result of the game is new knowledge about the world and a better understanding of how the world works. Interacting with other children during the game, the child develops his or her own style of behavior and communication. In short, play is critical to development because it is the way a child interacts with the world.

Through the game, children learn new skills and develop speech, thinking and logic, memory, attention and other mental functions. In games, children learn to follow the rules, control their behaviors, develop communication skills with peers and adults. Often the game becomes a way for children to cope with their difficult experiences and express their feelings of fear, anger, resentment, sadness and shame. The game also will bring pleasure, joy and a lot of other positive emotions to children- and the significance of this cannot be underestimated. Also, through the game, children learn to be proud of their success, which supports their self-esteem. Adequate self-esteem is the key to the full development of the individual.

The role of an adult in play is to support and encourage the child. This helps the child understand that his opinion is valuable, and his ideas and fantasies deserve respect.
