Dangers of reality TV is that they are not a true depiction of reality. These shows can be very addicting. People who watch these shows see behaviors that are extreme. This is not how life really is. People who make these shows choose people that cause the biggest commotion to bring in more ratings.
Dangers of computer gaming is that is can be addictive. Computer gaming is convenient because you can do it from the comfort of your own home. If money is involved, it can become very expensive as well.
Let's see for reality t.v. it is the lack of values. Kids are being raised by these shows that are NOT reality, but scripted drama for entertainment. Then these kids grow up thinking that is how life is, and they would like to live like that. For video games, it can most certainly be an addiction and isolate people. Kids today start playing video games at a very young age, and many of them are learning how to blow things up instead of playing house or building a treehouse with their neighborhood friends, which helps them grow emotionally and socially.
I do not think there are any wrong answers for this question except no answer. Since you aren't contrasting the two, it sounds like you are just asking for opinions on the dangers.
Computer gaming is often sexually graphic or violent. I believe that people become immune to the violence when it is repeated continuously in a mind. There are no consequences shown in computer gaming and violence is often imitated. You might check information from Columbine shootings for this evidence.
Computer gaming can be addictive, robbing people of their time, talents & resources,contributing to a society of recluses. Without socialization & interaction, what happens? This might be another interesting research opportunity.
The first danger in reality TV is that it isn't always reality. There are producers & photographers standing off scene to help guide and enhance the show. Many reality shows are scripted. Reality shows are cast often by looks and personality which only helps emphasize beauty according to Hollywood. Personalities are picked for entertainment.
Most people on reality TV are looking to make it big and are willing to do things that aren't necessarily moral or right just to make a name for themselves. Children watching reality TV might try to emulate actions they see which can be dangerous. The MTV show Jackass caused many home injuries for this reason.
I remember warnings my mother gave me, "Don't sit too close to the TV or watch for too long...you'll go blind!" However, I am not convinced that blindness actually occurs. Prolonged viewing may effect your vision, but it is more likely to effect your physical well-being.
In addition, one danger I see is the skewed version of "reality". Both reality TV and computer gaming (especially the ones with amazing graphics) tend to carry the viewer into a new interpretation of reality, and it isn't so. Reality TV is more scripted than most viewers realize. It isn't spontaneous at all, and far from reality.
