w. t . c. first television screens. then computer screens. now tablet a small screens. screens have inundated and changed our minds for a full decade now. and. the internet social networks games and videos devour one 3rd of our waking hours. the typical preschool child spends between 4 and 6 hours a day in front of a screen of some college. in nearly every country children are spending far more

time with screens than the recommended announce. there is a proliferation of and moaning studies. we're finding dramatic changes in the brain in the behavior of these mazes so we should be concerned about this. on your runs might be in danger plus we white of your 1st book are called because i know what it does to your brain. teenagers get to dictate. to do you screen generation really and i'm healthy generation there's a lot of questions out there are screens ok how much is ok how much is too much for my child. so how do you feel healthy digital habits. and what other scientific facts.

at this very moment number of trees across the whole world are studying the impact digital tools have on behavior the brain and medical health. this is a very young literature let me give you a little perspective. it takes about 20 years to establish an effect in science 20 years tablets and the fact that they began to be used by very young children is more sed 7 year old or 8 years old we're doing it commercially before we have actually done the science i would much rather we do the science 1st and then we say oh is it safe or not.

that alone was 1st founded by psychologists psychiatrists on pediatricians after in the field work with children. we have a toll on you sue brought just outside paris. imagine a young mother and her daughter malia in to see dr. for the 2nd time. your turn where is my princess though only hello ma'am have a seat. we'll talk this over again a bit how is our little malia coming along however she now 2 years and 4 months i was a bit worried because malia didn't talk much she had sudden mood changes to. so much in 20 years as a pediatrician talk to you has witnessed the shop rising screens in tiny children's

lives and the mounting problems all these children have interaction or disorders i have more of them than ever before the temperament disorders to clearly difficult children have always existed but there is a sharp rise of those with no concept of limits who bark at frustrations who have fits of anger or language problems poor language skills unstructured language or even none at all bad. bad alone no bad and by the way. your book are so similar should. be found in news on new. barely 6 months ago malia was spending up to 6 hours a day watching screens morning cartoons meals in front of the t.v. you tube videos on the mobile phone after naps take this interaction now whereas before she'd often be on the radio you just that a highly important word you just that a highly important word interactions it is key here because the screens had taken

the place of interactions that needed to take place between you 2 between dad and her and between you and her about it so clearly this altered things it did because screens are a major issue in public health today measure we absolutely must be aware of us. p.h.a. sions waiting has all the usual prevention campaign based in school but also messages to raise awareness of the dangers of screens. schools are also now wary of screens primary school teachers must cope with an increase in need and language disorders. today many professionals in the field of early child care suspect screens of being a cause of many of these disorders. numerous epidemiological studies conducted worldwide justify the rising concern. for and number of years people have tracked exposure to screens and young children and what they're

found is that on average if there are higher amounts of screen exposure this can be associated with negative outcomes and disruption to sleep disruption to attain. scientists consider that for toddlers ages 3 and under exposure is excessive when it exceeds 2 to 3 hours per day it is than ever seen. in 1970 s. most children didn't start watching t.v. before the age of 40. $41.00 3rd of toddlers under age to expose you currently exceeds 90 minutes by day keep them times to 3 keep them times to 3 hours per day even 6 in the us and. in our digital era many children spent over a 3rd of a way to notice absorbing video content. more to the results of

this. rather surprisingly it is difficult for scientists to answer that question. the phenomenon is more complex and it appears and experiments that must be carried out to analyze it sometimes rather odd. ducked into mitri christakis heads the center for child health behavior and brain development at seattle children's research institute. he's a pioneering research on small screen. we followed thousands of children from birth to age 7 and what we found was that the more television children watch before the age of 3 the more likely they were to have attentional problems later in life at school age. he and his team think these programs pace is what causes problems in children's brains. so the hypothesis that we had was that prolonged exposure to

that rapidly sequence media would pre-condition the mind to expect high levels of input and this would lead to inattention later in life. stated otherwise a young brain regularly exposed to high levels of pictures and sounds would in the long term after problems concentrating on tasks that require time such as reading and writing. the justice and soil them bodman set of actual observed problems in children being studied. because of an illogical studies or always subject to the criticism of the kit groover causal relationship the next logical step normally would be to conduct an experiment what we call a randomized control trial in this case that would mean taking infants exposing half of them to fast paced programming the other half to none and following them as

we did in our pretty logical studies for 7 years there would be no ethical or practical way to do that and so in a sense we were at impasse. the only work around conduct the experiment anyway but on young minds. so what we really kind of created was sort of t.v. for mice where we had the sounds corny with these lights to kind of put on a show if you will for the animals. the program is done the same time every day. we have lots of different cartoons that we layer on top of each other and then we change the frequency of the cartoon so that the my skin care. we have a lot of lights that surround the cages and we have them flashing the flashes

coincide with the sounds that we play. out about this show is not good you get for 6 hours per day in the mice that were giving the simulation to it started 10 days after birth and it goes for 40 days. dozens of young minds have undergone the treatment. behavior in study from every possible angle and compared to unexposed mice. the result the monitoring 6 hours a day in front of a small t.v. do not behave normally what we find with a normal mouse is that they'll stay around the perimeter here they like to explore but they want to stay safe when we take those mice that underwent the sensory stimulation and they have a much different pattern of behavior so they'll run around the maze like crazy and then they spend a lot of time going into the center of the me is which we would consider to be much more risky and so the way that we interpret that kind of behavior is that the mice

are impulsive. heightened impulsiveness but also cognitive problems. tests reveal learning difficulties you know a memory capacity a handful of clues that hint at concentration problems. what we see in humans in observational studies is that exposure to rapid paced program and early life decreases attention and increases impulsivity and we find the same thing to be true in a mouse model of the current state of evidence and 2019 cell phones and tablets now to our daily existence. they wriggle their way into our relationships even the most fundamental ones. today screens are suspected of harming heaven child relationships. from the how little make up t.

about in the beginning of the debate centered on t.v.'s being left on constantly running in the background a new t.v. shows unsuitable for tiny viewers this disrupts parent child interactions in today's world the issue is how greatly cell phone usage disrupts family relationships just how much does this device which we constantly keep by our size and which steals our attention or disrupt our interactions with loved ones. to answer this question the child an infant lab is currently monitoring 115 families in and around lynch of ping sweden. the aim is to gather precise data on families digital habits and their impact on cognitive development. studies on hundreds of infants demonstrate that the earlier cell phone screens make their ways into babies' lives the later they begin to speak even parents constant use of cell phones may hinder children's language development however as these

studies are based solely on parents reporting the data i'm not entirely reliable. for the 1st time linchpin university will collect precise data on baby's digital environments by placing spine microphones into baby's clothes. carry them down the list are not on the map at all analyze or use recordings shows what is actually happening. this access to the sounds in the home lets us count the number of words pronounced by adults and by inference the number of interactions occurring payday cornetto mock up at this doc so we can also identify sounds emitted by digital devices a dog to get taught you. with this method researchers can detect whether families digital habits are influencing their interactions with their baby's. and can evaluate the consequences on the later language development. on harvard that when

infants hear very few spoken words the language learning is different as our research demonstrates sensitive similarly the parents who are absorbed with electronic devices tend to spend less time talking to their babies therefore digital habits do have consequences to get taller me of the consequence. but this study on growing up in the digital world has only just begun. to confirm that the only presence of screens affects language acquisition even cognitive development we must wait until all these children under study have reached talking a. they're going on with the work of hearing programs that disrupt attention spans screen suspected of harming parent child relationships of hindering language learning. irrefutable proof is still lacking to condemn.
