caution screen! Consumption of electronic media and its impact on brain development

caution screen! Consumption of electronic media and its impact on brain development

after me today declared once again a student of eighth grade, that there are now studies that show that computer games to 2 hours daily good for children is, I finally roused to write the long waiting summary of the talk by brain scientist Professor Dr. Spitzer.

first needs to be made clear that our brain always learn. Learning is not a conscious decision in itself, but you decide WHAT you learn. Spitzer is a crash course in brain research, and he explained that the process we call learning, based on the brain is nothing other than the trail of information that we process.

is this, that these tracks are the more pronounced, the more often a piece of information is processed and the more emotionally charged the Enjoy the experience. How anyone can easily understand their own daily lives, we shape ourselves to things that caused us great joy, but also a lot of pain, physically and mentally, once and for all time. Just unforgettable experiences.

describes organic brain Spitzer the learning process with the emergence of a beaten track on a snowy meadow. The meadow is the millions of synapses in the brain, which are each a piece of information. By the information processing, the synapses are connected, so connected.

In view of the winter prairie: Runs only once a person from A to B on the track is soon blown away again. Run, however, several people again and again the same Route is a footpath from the trail and finally a way. The brain researchers say, therefore, assume that processing patterns are paved in the brain. The connection between synapses is measurably thicker. The deeper this facilitation is done, the faster and more reliable the information available.

on just this way, therefore, is how our thinking routines. For this too, any number of examples are found in everyday life. Very clear the character is when you experience no longer even aware of how you go through a routine, such as when you do not know how you got home (without drugs) or you are not sure afterwards if you completed , etc. has turned off.

summary So does that mean, not matter what information I supply to the brain, they will be paved by repetition. Active learning is called practicing the sport and Automation - trained reflexes.

Now back on screen media. Spitzer refers in his paper on a long-term study in New Zealand, published in the journal Lancet in 2004 (excerpt on TV consumption of young and adult body weight: http://www.thelancet.com/journals/lancet/article/PIIS0140- 6736% 2804% 2916675-0/abstract). Their findings can be predicted using only the basic knowledge of the above-given insight into the workings of the brain.

show First German statistics show that children sleep in this country an average of 7-8 hours, or about one-third of the day. In second place comes with about 5.5 hours of daily consumption of screen media. It can be divided in 3.5 h and 2 h PC TV.
In third place comes the school with about 4 to 4.5 h (all calculated on 7-day week). In other words, the largest source of information (always in the sense of data regardless of the content) of the screen consumption.

The aforementioned study in New Zealand has recorded more than 1,000 newborns and assists more than thirty years, the findings on the relationship of child and adolescent behavior and the adult people in every to win respect.
list without the individual numbers of the statistics, can cover the following links:
more TV consumption between 5 and 15 years, the more overweight the subjects had, the more likely they were smokers, the worse was their general fitness at age 30.

have already explained this purely biological observations. TV consumes considerably less energy then sleep. In addition to the viewing experience is part of many high-calorie foods such as chips, peanuts and candy. The embossed patterns in youth gather therefore purely metabolic moderately over the years the bacon.

More Results The study in brief:
  • the higher the consumption of television with 1 year, the safer and more ads with 7 years
  • the higher the consumption of television at age 5, the safer and more reading and spelling problems at 8 years
  • per higher the consumption of television to 5 years, the lower the educational level and social status at age 30

the last point a little more detailed information:
TV viewing at age 5
  • daily for 1 hour: 40% Uni- degree, 40% vocational qualification, 10% have no qualifications
  • daily 1 to 2 hours: about 25% of university degree, about 45% of vocational qualifications, about 5% with no qualifications
  • 2 to 3 hours daily: 20% university degree, about 40% of vocational qualifications, about 15% with no qualifications
  • daily for 3 hours: about 8% of university degree, about 40% of vocational qualifications, about . 25-30% with no qualifications are

As mentioned above the average German youth in the latter consumer group. Spitzer has expressly dismissed claims that the results are dependent on IQ, or the social status of parents. These factors have been excluded from the results already mentioned. Therefore, the incomplete percent totals.

Building on the basics of brain function Spitzer said these negative consequences from the perspective of brain research as follows. It is common knowledge that childhood lays the foundation for understanding the world and the subsequent handling of it. Even before the modern brain research reported sayings such as that of Matt and Hans pointed out.
Now, if a child makes such an impressive first experiences with the world of screen media, it takes about only two instead of five possible senses of sight and hearing.
Everyone knows the strong instinct of small children to touch everything and even better to have stuck in his mouth. It is touches and taps, cast and sniffs. It is stored in the brain all the sensations and experience the property in question, specifically associated with the appropriate Term. When you hear the word "apple", should be able to recall an image, a scent, a sound and a tactile feel to finish, shape and weight. A strong sensation, such as fragrance or image can evoke whole experience again. This is exactly the networked information in the brain.

Now the so-called average children get in Germany (and elsewhere) their experiences about their environment and the people largely through the vision of blurred images, flickering and hearing the noise from more or less bad speakers. First, on this way, the other senses or not trained hard and wither. This is evident in stunted fine motor skills, Just look at manuscripts. Second, language is not networked with extensive experience. This is evident in the developing power of expression in the heavy-understanding of the relationships in the real world, and finally in the school grades.
Spitzer observes, that it can be shown that an average intelligent children are affected much more so than the average intelligent peers. So the gap is thus further apart.
For these grades, in turn, result in the above statistics on skills and consequently to social status.
is hereby established full focus and again to understand the operation of the brain, that the expression of predetermined screen use as an adolescent my future social status, apart from bequests and other misfortune and see.

As Spitzer notes pointedly, yet not a single word about the contents of the screen consumption was said. It was only about perception and information processing in the brain.

The explanations can now be easily derived, the potential consequences of the contents. Countless hours to the mentioned low energy consumption and depletion of the senses when screen use the thousands of repetitions of commercials to get high-energy food, the orbital planes and their traces in the brain. The result I always enjoy the most on advertising in ethics education: Assigning students (and not only) can be in complete perfection advertising slogans, product or brand, and often still hum the jingle to it.
The saying "It's like in the film / cinema / television," shows where we take our benchmarks.

If Spitzer 80%, according to the German television program now have power to content, it is not surprising that a German study has shown in the analysis of crime statistics that the TV consumption predicted at 14 years, the frequency of violence as an adult does.

be mentioned all the information learned more, the more it emotionally be experienced. The quality of video games is measured for most of the quality of the graphical representation and the fun that the game allows. Fun and learning success are our strongest emotions. Just as children's successes are memorable, just as serious failures.

PC gamers often lend to outsiders almost unbelievable in their virtual worlds. You can reach speeds in the operation of their hardware that often the audience is no longer comprehensible. There are charts of actions per minute, measured at the level where the player can (http://en.wikipedia.org/wiki/Actions_per_minute). Better can the correctness of the findings summarized here no evidence of brain research.

The question is then how are these incredible abilities of the people in his daily life, useful in school, work and social environment. If I decide to perfect me in hundreds of hours of practice in playing a single role-playing, we should at least ask who benefits from these "costs" it pops out for me.
Although the market for PC-game developers and testers just expanding, it is worth considering whether my career will go in that direction, and whether a rudimentary communication skills and social impoverishment is a reasonable price for it.

The study from New Zealand has also shown that consumption screen for most young people do not seem to fame and wealth, such as in the media or computer-game industry leads. my

The accuracy of the presentation of Spitzer observing a day I can. Young people who are frequently talk about TV programs and computer games, or worse still use the same mobile device at school, their grade point average is not very reliable at the peak.

Coming back to the eighth grader and his studies on the usefulness of screen use among adolescents: Spitzer looks at the pointing out that the TV and PC game industry is a market of around 20 billion EURO is. A few years ago flew the dozen supposedly reputable "scientists", which would have proven that tobacco smoke is quite healthy. Now, smoking is still far too many people. Probably not a claim but still, he was doing himself and his health so that something good ...

What is a random variable? A real debate

who occupies a stochastic rate that quickly gets an intuitive understanding of random variables. My experience was that I quickly had an intuitive understanding to solve simple exercises could, and later suffered greatly from not having a mathematical understanding of a random variable. My girlfriend is currently preparing for exam students and I see my old mistakes again in their students: it is possible to operate without understanding stochastic random variables, but then later concepts are difficult. I hope that after this article, the interested reader can do both: the definition of formal proofs without using intuition to lose for chance to bring every student:).

A random variable is a function. A what? Yes, exactly. Also a deterministic and somewhat unexpected and not a bit random. It's pretty maps no matter which room in which room the random variable. I choose you an example: hot

Our random variable X . The random variable X forms of space

A = {1,2,3}

in the room

B = {W, L}

from. Here W is a walrus and L is a leopard. What I mean is: random variables operate in areas, which need not be algebraic. A random variable can map anything to anything.

random variables, we can examine an example of good. We definierne X as follows:

X (1) = W , X (2) = W , X (3) = L .

But where is there by chance? There is none. Stochastics is pure mathematics, mathematics of functions on spaces and their properties. The rooms are particularly well suited to so real, random to describe events. If you do that it runs statistics. In our example, I could claim to illustrate that A the goals in a game show are B are the things that can be found behind the gates. But the situation would not add anything.

What really does is measure of probability. You need for every room A and B still a tape measure with which we can measure a subset ⊂ A and b ⊂ B . We say "likely", but in truth we measure only. By that I mean, you are the size. As with a ruler. If Stochastics say that the probability is 1 / 3! Then they think: I took a ruler and measured, and it is 1 / 3 size. For the general confusion, we call this scale "probability", although it again nothing happens.

I define now a tape measure for A , but none for B (later, we are looking for a tape measure B, I promise). I call my tape measure P . And I say P ({1}) = 1 / 3. P ({2}) = 1 / 3. P ({3}) = 1 / 3. P is the uniform distribution on A . Perhaps an eagle eye drops on that measure that P actually all subsets a ⊂ A may be what is, for example P ({1,2})? It is the property of tape measures that you can measure the components alone and then sum up the lengths.

P ({1,2}) = P ({1}) + P ({2}) = 2 / 3.

said, the stochastics is great in it, measure, and we have not B measured. Which, if you will, a central feature of the stochastics is that if you measure A can and there is a random variable of A after B has , then we can build a measure of B . Stochastic description of this scale derived by a notation that seems only to invent a completely different look than the rest of mathematics. They write things like P (X = L). What do you mean? (Most students help themselves by understanding the metaphorical expression, and read: "probability that X = L") I use a more common notation, and then explain the Stochastikernotation later.

Ok, we seek a measure of B . We have P, which is the measure of A , and We have X, the random variable. I propose that as a measuring tape to B function. The -1 in the exponent means inverse function (see, eg here), the circle means "after" and I mean only .

order for us to understand the situation better we calculate .

X -1 ({W}) are all pre-images of walrus, that is

X -1 ({W}) = {1,2}.

And so

,

and analog

.

Our goal was, a tape measure for B to have, we have achieved it? There are two important criteria for a good tape measure in stochastics. Since they are called "probability measures". The first is:

  • If you measure the whole space, we obtain as a result


what we have achieved in our example, because 2 / 3 + 1 / 3 = 1 It applies to all variables on probability measures induced, and I recommend the reader to prove that, it's really easy:).

The second is:

  • If we measure something, we can also use it just as well cut up into parts, measure the parts and their sum must give the whole


Wikipedia expresses something less prosaic like this:

with A i pairwise disjoint.

And here one would have to go back a bit further, I was only a short version: It is a sad reality of mathematics, probability spaces that you can not cut up as desired. In our rather small probability spaces, everything is still fun and possible, but exclude even at only slightly more complicated spaces must be the most mathematically possible sawing up to meet the first criterion. So one has to find a probability space and allowed to specify a list of his sawing. This list of allowed sawing is called the "σ-algebra" of the probability space. The σ-algebra of some probability space C thus contains only the subset of C that can we measure it.

And now we can finally explain what a probability variable:). A function X : A → B a probability variable is when you can generate from it a probability measure on B. Why should not that be possible? Now, if X regarding the σ-algebras "incompatible" is.

For example, let's assume we know a probability measure on A , namely P .

Then we would like to see is a probability. Why should this be? Well, X -1 could have a picture that is not a valid argument for P (Gülten arguments are valid for P "sawing" of A , and those are elements of the σ-algebra to A ). And this is really all the magic. We require that X -1 , valid sawing B to valid sawing A maps. Or formalistic, the calligraphic A is the σ-algebra A to is the calligraphic B the σ-algebra B to :

. What should a

notice is that this condition is fairly mild. You have to go pretty far to find a function that satisfies the condition is not (although technically meet almost all the functions of the condition NOT).

Many students are confronted with this condition and think: Aha, X must be surjective! But X must be neither surjective nor injective. My Blog inclined reader has learned that the condition expresses the compatibility the σ-algebras of, nothing else.

It is still open, our notation is difficult to type and write. And therefore, the stochastics have devised a special notation that goes against all conventions of mathematics, but much shorter than mine and so popular:



Well, and also is the spelling suggestion. P ( X = b ) to read to you as: The probability that X = b, which sounds cool, and fits well into the intuition about probabilities, but it fits just not as good for defining the world of stochastics not in the X = b randomly is.

I hope that after this article, the interested reader can do both: the definition of formal proofs without using intuition to lose for chance to bring every student:).
