  1. 1. It has been found that playing video games improves a range of cognitive skills, like visuo-spatial and attention skills. Karni et al (2003) showed that cognitive experiences like this can lead to changes in the brain which are long term.
  2. 2. Instant Messaging and Facebook have encouraged communication with others. 88% of adolescents use it to communicate with friends. 
  3. 3. Researchers believe the internet encourage self disclosure and self disclosure is a key contributor to relationship formation. Reduced visual, auditory and social status cues can encourages self disclosure ion those who might be self conscious and shy. The improved quality of internet relationships had added benefits of acting as a buffer against stressors in adolescence.
  4. 4. In 2009 Gentile conducted three studies, in 3 countries with 3 age groups, he found in the US part of the study (161 college students) that those who played prosocial games behaved more helpfully towards another student in a later task. In a Japanese sample prosocial behaviour was related to prosocial game playing over a four month period.
  5. 5. Some video games promote physical activity also might be a way of reversing effects of a sedentary lifestyle. Research has shown that video games treble energy expenditure. Can help those who lack the confidence to try something and new games are being used to help the visually impaired exercise, important because these children as a result of sight problems do not find it easy to take healthy exercise and so are at a higher risk of obesity. Games such as tennis are played without visual feedback using audio and vibro-tactile feedback.
  6. 6.  So far these games have been very successful in getting sight impaired people to exercise vigorously, though the sample sizes have been very small.  However it has been argues that they are not a replacement for traditional forms of exercise which burns approx. four times more calories.
