People Unplugged – new Website

How does TV effect individuals and society?

A new website looking at the effects of TV has just gone live. Instead of short blog posts and/or links, PeopleUnplugged.org will specialize in longer form essays and books reviews. Wilfred Clifton is the webmaster and author and in charge of the graphics. I am also a contributor, writing as Terry Severson.

Why Are Parents Getting Arrested for Letting Their Kids Go to the Park Alone?

https://flic.kr/p/8baLxY

Is your child ready for grade one? According to a 1979 checklist there are number of things to look for, such as:

“3. Can your child tell, in such a way that his speech is understood by a school crossing guard or policeman, where he lives?

9. Can he be away from you all day without being upset?

8. Can he travel alone in the neighborhood (four to eight blocks) to store, school, playground, or to a friend’s home?”

So in 1979 (not that long ago) it was considered normal for a 5 year old to be able to walk eight blocks unsupervised to the “store, school, playground, or to a friend’s home…”

Now, parents are being arrested for letting their kids go outside unsupervised:

Does too much TV damage the brain?

Scientists at  Tohoku University in Japan decided to look at the brains of children (ages 5 to 18) and look for any differences between those who watched lots of TV and those who watched much less.

MRI brain scans showed children who spent the most hours in front of the box had greater amounts of grey matter in regions around the frontopolar cortex – the area at the front of the frontal lobe. But this increased volume was a negative thing as it was linked with lower verbal intelligence, said the authors, from Tohoku University in the city of Sendai. They suggested grey matter could be compared to body weight and said these brain areas need to be pruned during childhood in order to operate efficiently.”

Dopamine and Addiction

Dopamine-Levels

 

 

via:  Gamer Therapist

Drug addiction, addiction to gambling, and food and video games and TV, all have dopamine as the common denominator:

The brain registers all pleasures in the same way, whether they originate with a psychoactive drug, a monetary reward, a sexual encounter, or a satisfying meal. In the brain, pleasure has a distinct signature: the release of the neurotransmitter dopamine in the nucleus accumbens, a cluster of nerve cells lying underneath the cerebral cortex (see illustration). Dopamine release in the nucleus accumbens is so consistently tied with pleasure that neuroscientists refer to the region as the brain’s pleasure center.

All drugs of abuse, from nicotine to heroin, cause a particularly powerful surge of dopamine in the nucleus accumbens. The likelihood that the use of a drug or participation in a rewarding activity will lead to addiction is directly linked to the speed with which it promotes dopamine release, the intensity of that release, and the reliability of that release.”

Media, Children & Novelty Seekers

Neuro Research Project has a very interesting post on risk-taking, dopamine, and Dr. Christakis’s mouse study.

Note Neuro Research Project ‘s post is based on Dr. Sheikh Arshad Saeed‘s ideas:

NeuroNotes

Dopamine addiction is an overlooked problem..  Dopamine is the most addictive substance on the planet, a neurotransmitter produced in our own body.

This TEDx video (Media and Children), by Dimitri Christakis, a pediatrician, parent, and researcher,  shows young mice taking risks after being exposed to TV,  6 hours a day,  for 42 days. The mice continued to take more (potentially life threatening) risks the longer they were exposed to TV.

Long term exposure to specific types of media, especially in young developing brains, appears to corrupt the reward system;  fewer dopamine receptors.  Over-stimulation from media may produce the same effects on the brain as drugs, i.e. heroin and cocaine.  These drugs artificially extracts more dopamine from nerve cells in the brain, requiring more to get high or satisfied over time.   An abundance of dopamine, due to a low density of dopamine receptors, appears to lead to unhealthy risk-taking.  Risk-taking comes in…
