Myths and ptifails about ” attention deficit “
28
Nov
It is common to associate the deficit of attention to the use of many devices , common now
because of digital technology , most researchers have stated that it is a myth , but let the cognitive point of view what happens .
Physiologically, the brain receives new information by the thalamus , it is a filter of attention, if you are talking to someone in a noisy environment, it blocks coming from outside to keep the information coming from the conversation.
If we train it is possible to change the ” task” , for example , leave the TV and read a text, but very things that draw the attention of the thalamus and the filter does not work , can cause a “dispersion” or so-called attention deficit , and these cases are many in the modern world .
Nerve impulses transmitted to the processing center , which is the cortex, a kind of shell the kernels of the brain , is capable of identifying different stimuli by the senses , for example, you eat the palate is active and is also talking , both information will pass through the thalamus and cortex to different region , which corresponds to the hearing ( conversation) and taste ( taste).
After recognizing the stimulus , the cortex sends information to the hippocampus , is that he is the commander of memory, ie , select what is stored and discards what he thinks essential, but this depends on the encouragement you give, eg , my father’s speech is not important, then discard , just want to enjoy and then forget , then discard .
Ended up seeing a basketball game with some friends , the game goes to a place to save because you felt happy and had an incentive to save , but saw the people that are in the game , and did not pay attention (not reinforced stimulus) , then it goes to the place where you can forget, or ever forget the next moment .
While the hippocampus works , you will giving a “featured” emotional all the information it deems important , helping to highlight what should be labeled, so it gives more value to certain information that you tell the brain that is important.
So forgetfulness is bound to like , to be desired and also to train the brain to what is important , most of the information we make ” an obligation ” is discarded .
This information is sent to the region called the amygdala (not to be confused with the throat), which gives an “emotional warmth ” to information , highlighting what is most striking to us .
So what ” we want to keep it” can not be a moment of “attention deficit”, for example : environmental discomfort , tiredness or something nasty side
Informational nutrition

Like most people today eat badly information , confuse this phenomenon with the advent of
the Internet and then the web application (is just an application on internet) .
The phenomenon of the information , as we highlight in another post , predates the internet and long before the Web , the question of the abundance of information was already studied in the 40s and an important aspect of this book is ” Information Anxiety ” Wurman .
But the appearance was worsened with technology , and Professor Larry Rosen of California State University and is a researcher of the ” psychology of technology” , states that the average attention span of many people now , is only 3 to 5 minutes then get distracted and fail to finish what they started .
Like an immense table all sorts of food in Brazil characteristic of self -service , but around the world can be thought of as a beautiful Christmas table , you should not eat everything and can get sick if you do this .
For information is the same thing, then we need to select what, how much and how we ” feed ” of information , and this is what I call “informational nutrition.”
According to Dr. Adam Gazzaley , who wrote The Distracted Mind the brain may seem limitless in its potential , or limitations such as processing speed , attention limits , limitations on work, sensitivity to interference . Both external , and internal .
Clarifies the book , there has been an explosion in the variety and diversity of electronic media . Portable devices can provide maximum information from a computer , he then asks the questions :
• Have you ever worked on a document while listening to a song and had to open an email ?
• Have you ever watched television while surfing the web and receiving text messages ?
The various media devices that children use both , may be even higher than adults , and this kind of behavior is not going away anytime soon.
But this can influence our cognitive capacity and performance of our brain , the book tells how to control these issues .
The bionic man today

He already has human functions : walk, talk , and he has a beating heart (which can do exactly the function of
the human heart ) , but its purpose is not human , is to show the human functions made by technology, and that reason they are first totally bionic man in the world ( bionic man)
So he is ” a mixture of body parts , the bionic man is an amalgam of the most advanced human prostheses ,” as stated in the magazine LiveScience , ” the robotic limbs to artificial organs Circulatory System pumping blood ,” the floor and simulations take as perfect man .
The creature ” came to life ” in ” The Incredible Bionic Man ,” which premiered on Sunday ( October 20 ) at the Smithsonian Channel in a video (see the video of the Bionic Man) .
The devices used in the different organs were developed by different laboratories , such as the eye and the heart, such as prostheses that can be implanted in humans.
Still just merely a machine , without any kind of sense , the fiction of man is six million dollars , or Bicentennial Man , are still in the cinema .

More confused minds the Web

In a report in brazilian magazine Epoca, also the book of Mark Bauerlein to Nicholas Carr, author 
of The dumbest generation there is a pessimistic analysis in that it anticipates a new Dark Age , when individuals who are now children and adolescents reach maturity .
In analyzing this author in Epoca magazine , ” once youthful minds restless and full of knowledge , what we see in schools is an anti -intellectual culture and consumerism ” , attributed to Bauerlein , a professor at Emory University in Georgia , which oversees studies about American cultural life .
His study on the influence of digital media was done with 81,000 American high school students and second it was found that 90 % ” read or study ” less than five hours per week , and spend many hours watching TV , surfing the internet or playing video games , an average of 6 hours per week , and then takes to conclusions , saying ” do not know practically nothing of history” , etc. .
I do not know if the data of the 60 youth would be different , just did not have internet and had the war in Vietnam and Brazil , were times of military rule , and even speak the word dictatorship was forbidden , educational systems were repressive and little inventive , luckily I entered the first class of computing and had some regular teachers , who read and reported on the country’s history , but was also minority.
We read romance, but it was something with sugar water , but we really wanted was a color TV to watch the Brazil game , can not remember if he sang ” this is a country that will put forward will ” actually liked math and I only understand policy when I entered the university, but I am the fruit of the hippie generation and the ” hairy ” .
The lessons were always silly stories , had to memorize dates and know what were the ” national heroes ” finally no critical analysis of reality , the university was reading because it was an alternative set of left and needed to have arguments against the ” dictatorship ” today I thank the “rebels ” of my youth , without them I would also be a ” dumbest generation” .
How long we were in front of the TV culture engulfing canned ? what they say about Arab or Muslim culture in our newspapers ? someone knows something of African culture ? Whose dumpest generation ?
The problems that befell this generation has no connection to the lost generation (1914 – 1924) , the baby boomers generation ( 46-64 ) and hippie generation ( 64-84 ) ? is it only now are ” dumbest ” ?
