Port communicationWill playing with mobile phones for a long time make you less smart? recently，There are media reports，An ongoing study by the National Institutes of Health (NIH) shows，Children who heavily use smart products to play video games，There are changes in the "patterns" of the brain。Data display，Children aged 9 to 10 who use such electronic products for more than 7 hours a day，The cerebral cortex shows signs of premature thinning。The cerebral cortex is the outermost cortex of the brain，Responsible for processing sensory information。
According to Dowling, the doctor who conducted the study："We don't know if this is related to screen time，Not sure if that's a bad thing。"As soon as the news came out，Many parents can’t sit still.。“I only know that staring at the screen of electronic products for a long time is bad for your eyesight.，I didn’t expect it would affect brain development，Is this true? "A parent friend said。
really，heard the news，Many people want to know，Is the research conclusion valid?，What is the impact of electronic products on children?，How should we guide them away from，Avoid gaming addiction? Many things have multiple causes and effects and cannot be judged. "About the long-term use of electronic technology products，Including looking at the screen for too long is harmful to the cerebral cortex、Empirical research on the impact on human psychology and physiology，Have been working abroad for many years。
But it is only an empirical study of some cases，At present, there is no unified conclusion internationally。therefore，I don’t think there is a universally applicable scientific question。”December 18th，Zhang Haibo, director of the Children's Media Literacy Education Research Center of the China Youth Palace Association, said in an interview with a reporter from Science and Technology Daily。 Zhang Haibo said，Many of the studies being done now are correlational studies，But many things have multiple causes and one effect.，cannot prove the inevitability of it。
Some current studies show，Such as some fragmented reading on the Internet，It may have a certain impact on children, especially in forming relatively good reading and writing habits.。 on this issue，Lei Li, a professor at the Department of Psychology at Renmin University of China, also said，From the research design，It is not yet possible to determine the impact of playing with mobile phones on brain structure。
to some extent，Playing with mobile phones is related to brain differences，But what is the impact of playing with mobile phones on brain structure?，Or is it that the structure of the brain itself is different?。This requires measuring the brain structure of the experimental population before using mobile phones.，and then every once in a while，Such as three months、half a year、Follow up again in one year，See what changes will happen to the cerebral cortex。
"But it's actually very difficult to do，On the one hand, mobile phones have become very popular，In addition, what each individual does with their mobile phone is also different.，If some students use their mobile phones to check information、Also playing games、watch video，This makes it difficult to define the impact of mobile phone use on brain structure.。"Leili said。 Huaxia Qixin In the above research，The results also show，Children who stare at screens for more than two hours a day，Poor performance on language and reasoning tests。
In this regard，Zhang Yunhong, a researcher at the China Institute of Standardization, believes that，This research conclusion is possible，But is it scientifically correct?，It also needs to be based on their experimental design、Determine whether experimental control and data processing are scientific and standardized。According to the research results of some previous scientists，Thinning of the cerebral cortex may mean reduced learning ability，Such as decreased concentration, etc.，As for the specific aspects of decline that will result, it still needs to be verified through experiments.。
Looking at electronic screens for a long time affects cognitive ability “From the perspective of usage time，The amount of time children spend on screens takes away from other developmentally important activities，Such as parent-child communication、Outdoor sports etc.。Previous research has shown，Compared with paper reading，Electronic reading is more susceptible to external interference, making it difficult to concentrate.。
Other electronic media，such as TV shows and video games，It has a high level of stimulation and rich content that constantly distracts children.。There is much evidence that prolonged exposure to electronic media is a risk factor for attention problems in children。Previous studies of adults have found this problem，And the impact of different types and designs of electronic screens is also different.，It may be related to the subjective quality of the electronic screen。
Based on this speculation，Prolonged screen time may have an impact on children's brain development，May affect attention ability、emotional processing ability、social skills etc.。
Current research on the psychological effects of prolonged screen time on children、There are relatively few studies on the impact of behavioral and social abilities，Experiments in this area can help researchers
Require
higher，Scientific and reasonable design is required，As the issue of the impact of electronic screens on children's development draws increasing public attention，There will be more and more research in this area。"Zhang Yunhong said。
Zhang Yunhong said，In the past, many parents were worried about being exposed to electronic screens for a long time.，Children’s vision will be affected，In fact, this is just the surface phenomenon that everyone can see.，Before vision problems manifest themselves，child's cognition、Emotional and social abilities may be affected to a greater extent。 previously，Her research on the changes in college students after watching cartoons for one hour showed that，Decreased subconscious attention and emotional processing abilities。
Playing Pad for 1 hour will have an impact on face processing ability，Long-term use of poor electronic screens can even reduce the ability to inhibit reactions。 Zhang Yunhong explained，The daily phenomenon corresponding to the decline in face processing ability is something people often talk about.：Seem to have seen、But I can’t remember where I saw it or who it is。Recognize this as a human face，But we can’t quickly retrieve the information behind this face.，It means that the ability to process faces is reduced.。
"If adults are still like this，Effects on children may be more severe，After all, children’s abilities are still in the process of development.，not mature yet。"Zhang Yunhong emphasized。
Not just cognitive abilities，at Teacher Education College of Shaoxing University of Arts and Sciences、From the perspective of Zhou Hui, Ph.D. in Developmental Psychology from East China Normal University，At present, domestic research groups on game addiction are mainly concentrated on adolescent groups and college students.，Results show that children with game addiction are more likely to have emotional and behavioral problems。
If research shows that children addicted to gaming，They are more likely to have anxiety in school、depression、social problems、Disciplinary behavior、aggressive behavior、The scores for extraverted behavior and the total score for behavioral problems were higher than those of normal children.，This suggests that children addicted to video games have more psychological and behavioral problems。
“Learning new knowledge and skills is the main task of children，The subjects selected in this study were children in the age group of 9 to 10 years old，In the acquisition of reading ability，Just learn to decode single words，Master voice skills、An important period of glyph analysis。If at this stage，Children spend a lot of time playing video games，will affect them in time、Be proficient in necessary skills，Ultimately it will inevitably affect the development of their learning ability。"Zhou Hui said。
Zhou Hui said，The cerebral cortex is the material basis for people's conscious activities。Different areas of the cerebral cortex are associated with different cognitive functions。Research shows，As the brain develops and ages、and pathological changes，Cortical thickness will show significant changes in corresponding areas，That is, cortical thickness represents the development and aging of brain tissue to a certain extent.。
There are results showing，Video game addiction not only affects children psychologically and behaviorally，It will also affect its physiological mechanism，But what specific cognitive functions are involved in children?，To be further determined by research。 Stay away from electronic screens. Parents should teach by words and deeds “In terms of using electronic screens,，Parents should limit children’s screen time，Especially younger children，The younger you are, the worse your self-control is.，Parents should help choose content that is beneficial to children and supervise their children’s use。
How to keep children away from electronic products，Avoid gaming addiction，Parents can consciously guide their children to participate in more real-life activities，Spend more time with your children，Guide children to read more，read good books，If conditions permit, you can travel with your children，Let children have more contact with nature，Promote children’s brain development with the rich stimulation of nature，Help children reduce screen time。"Zhang Yunhong said。
“Many parents now pay too much attention to the time their children use electronic products.，actually，Content selection is more important，What content is suitable for children of different ages?，This issue deserves special attention。"Zhang Haibo said，Now children are online、The time for playing games is mainly outside class，therefore，Parents or families are the most important line of defense to prevent children from becoming addicted to online games.。
previously，The research team of the Children's Media Literacy Education Research Center of the China Youth Palace Association once conducted a survey，The results show，Teenagers addicted to online games，It is often due to four types of problems in the parent-child relationship:：One is “don’t understand”，That means parents don’t understand what their children are doing online；The second is "poor relationship"，That is, parents have not established a good parent-child relationship with their children both online and offline.；The third is "lack of guidance"，That is, parents let their children play with mobile phones or computers，There is no necessary agreement and guidance in terms of time and content.；The fourth is "bad demonstration"，That is to say, the parents themselves are also addicted to the Internet.。
therefore，Zhang Haibo pointed out，For kids to play online games，Parents must avoid both extremes，Some people think that online games are a scourge，Parents take control of the Internet，Never let children access online games，On the contrary, this will stimulate children's rebellious psychology；The second is to allow the "electronic nanny" to control the children，Just put the phone、Throwing electronic products to children。
actually，Overcontrol and overindulgence，It’s not real education，And it is easy to make the situation of teenagers addicted to online games more serious.。What's more important，Parents must set a good example，First of all, you cannot be an addict to online games.。
“Parents need to establish a trustworthy parent-child relationship with their children，Children trust their parents，will be willing to talk to their parents about what to do online，If children are on the Internet and in reality，speech、Behaviors are consistent，Basically there will be no problem。"Leili said。(Reporter Fu Lili)
