Often holding a cell phone or tablet out of control , Aimless microblogging , Shopping on Taobao ……

If there is , Then we need to pay attention to , This uncontrollable Internet addiction , It is a kind of barrier called Internet use （IUD） Health problems , And this kind of problem , Will affect your speak Ability .

Barriers to Internet use , Specifically, often uncontrolled Internet browsing , But the browsing information doesn't point to , Just out of an uncontrollable habitual action .

A recent study was published in an academic journal 《 Public science library ： comprehensive 》 Medical research on shows , Internet use disorders can affect the brain , Change the regional structure of the brain that controls the language system .

Simply speaking , Namely ：

Too many microblogs , Don't speak neatly .

Scared, I quickly put down my cell phone .

Yes 60 Volunteers conducted the experiment

The research results come from an academic team of the medical school of the University of PEC in Hungary .

The team's latest experiment shows , Barriers to Internet use （IUD） It will change the structure of the brain language region , And then affect the ability to speak .

The experiment is designed like this ：

First use the Internet to use the questionnaire （PIUQ）, Yes 60 The subjects' Internet addiction was evaluated exponentially , Then language experiments were conducted on all participants , And in this process, the brains of the subjects were Nuclear magnetic resonance scanning .

In the process , Get the barrier of Internet use and Changes in brain structure The relevance of .

The whole experiment was paid 60 Volunteers , Age 18-30 Between the ages of , Half of them are men and women . meanwhile , Make sure that all volunteers know nothing about the purpose of the experiment .

In this experiment , The research team adopted 2 Experimental tools ：

First of all Internet usage questionnaire The design of the .

The questionnaire consists of 18 A project 3 Most of the components , Including obsessive-compulsive disorder （ Be obsessed ）、 Neglect and control disorders ,3 Each of them has 6 A question , Measure the obsession of the questionnaire objects with the Internet 、 Due to the absence of Internet on real life , And self-control .

All questions are Five point Likert scale answer , Compare and score different answers , The higher the roll score , It means the higher the degree of addiction .

besides , The questionnaire also introduces two subjective questions , As well as personal depression and anxiety, these psychological factors that affect the subjects' online behavior were evaluated .

Specific scores and questionnaire details , That's true ：

The second is Language experiments .

The experimental team did not use the semantic experiment of verbal fluency task commonly used in similar experiments , But with phonemic experiments .

The so-called verbal fluency task , It is a common tool for evaluating language performance , Including vocabulary knowledge 、 Vocabulary retrieval ability and executive control ability , It usually includes semantic and phonemic parts . The difference between the two is , Semantics requires the experimenter to say words related to categories , Phonemes require the experimenter to say words beginning with a specific letter .

As for the reason , According to the research team , Phoneme experiment can better reflect the ability of behavior control and the activation degree of frontal lobe , And the above two factors , It can better reflect the connection between Internet use disorders and brain structure .

Specific language experiment design , Include 7 Period 30 Second long rest and 30 Second active period .

During the event , The experimenter needs to be in 7 Within one cycle , In turn S、K、E、T、L、A、N As an initial , Say as many Hungarian words as possible .

Internet addiction , It really affects speaking

Next is the experimental results , Studies have shown that , Internet questionnaire scores and brain BOLD fMRI The relationship between is as follows ：

When conducting language experiments , The subscale of Internet use questionnaire and bilateral precuneus of brain 、 Bilateral cingulate gyrus （PCC）、 There is a negative correlation between the inactivation of the left subcallosal cortex and the left orbitofrontal cortex .

Total score of questionnaire , With bilateral precuneus gyrus and bilateral PCC The inactivation of is negatively correlated , Subjective question 2 Score with right thalamus 、 There is a negative correlation between the inactivation of the right parahippocampal gyrus and the right bilateral cingulate gyrus .

Subjective question 1, There is no obvious correlation .

And Broca's area of the brain, which is closely related to human language ability , It was found that PIUQ Ignore component and left occipital pole 、 Left lateral occipital cortex （LOC） And the endothelial layer of zuoka PPI There is a negative correlation between .

PIUQ Infatuation with the left LOC、 Arkansas and caudate nuclei in the left carpel PPI There is a negative correlation , and PIUQ The total amount is also related to the left caudate nucleus 、LOC It is negatively correlated with Arkansas in the left carpel .

The problem rate indicating the degree of subjective addiction （Q1） And left occipital pole 、LOC、 Occipital lobar gyrus 、 Middle frontal gyrus and anterior ventral gyrus PPI There is a negative correlation .

in other words , Experimental data confirm , Barriers to Internet use （IUD） It will reduce your speaking Fluency .

But the author of the paper also explained in the research ,IUD The change mechanism of language ability , It is in the process of language processing and cognitive control , Or is it because of the decline of general cognitive ability .

however ,IUD The negative effect mechanism on personal language fluency , Maybe it's because two nervous systems have been changed ：

One is DMN, Brain default network , And brain consciousness 、 mood 、 Episodic memory is closely related .

The other is the signal interdependence between Broca's area and occipital lobe .

Although the conclusion about the mechanism of brain action is still in “ Probably ” Stage , But one thing is certain ：

Play with the mobile phone and brush the tablet to automatic control , Otherwise, the real words will not be easy to say .（ Manual formation ）
