Quote:"When these people come off-line, they suffer increased negative mood—just like people coming off illegal drugs like Ecstasy," says researcher Phil Reed of Swansea University in the UK. - See more at: http://www.boston.com/lifestyle/health/2...uTggw.dpuf
Quote:Some psychologists argue video game and internet-dependence share the characteristics of other addictions, including emotional shutdown, lack of concentration and withdrawal symptoms if the gadgets are removed. The culprit, they argue, is dopamine; a brain chemical we produce when we see something that is new and stimulating or experience pleasure. We produce more when we drink alcohol, listen to music, have sex, or play a video game. We pump it out in a spurt if we have drugs such as cocaine. Research has shown it's related to arousal, addiction and reward. Hence, kids become aggressive, irritable and hostile when screens are turned off.
Quote:For this study, 60 adults, average age about 24, took a battery of tests that examined their Internet use, their moods and feelings, including the potential for anxiety or depression, and even if they had some autistic traits.
All participants then used the Internet for 15 minutes. Immediately after, they again answered questionnaires to judge their mood and anxiety level.
Of the 60 people, 32 were deemed problematic and/or high Internet users and 28 were low Internet users.
Well, certainly more studies are needed because there are many reasons why individuals would turn to the internet, and not all of the reasons would be negative.
