I found this part very interesting. The emotionally stimulating is
favoured by memory, and can be both good or disturbing. Good posting!

In an experiment at the German Sport University in Cologne in 2007,
boys from 12 to 14 spent an hour each night playing video games after
they finished homework.
On alternate nights, the boys spent an hour watching an exciting
movie, like Harry Potter or Star Trek, rather than playing video
games. That allowed the researchers to compare the effect of video
games and TV.
The researchers looked at how the use of these media affected the
boysbrainwave patterns while sleeping and their ability to remember
their homework in the subsequent days. They found that playing video
games led to markedly lower sleep quality than watching TV, and also
led to a significant decline in the boys' ability to remember
vocabulary words. The findings were published
<http://pediatrics.aappublications.org/cgi/content/abstract/120/5/978>
in the journal Pediatrics.
Markus Dworak, a researcher who led the study and is now a
neuroscientist at Harvard
<http://topics.nytimes.com/top/reference/timestopics/organizations/h/harvard_university/index.html?inline=nyt-org>,
said it was not clear whether the boys' learning suffered because
sleep was disrupted or, as he speculates, also because the intensity
of the game experience overrode the brain's recording of the vocabulary.
When you look at vocabulary and look at huge stimulus after that, your
brain has to decide which information to store,he said. Your brain
might favor the emotionally stimulating information over the vocabulary.
