What are some benefits and disadvantages to adolescents' increased use of media and technology, such as the Internet?
What will be an ideal response?
A good answer would include the following key points:
- Surveys indicate that adolescents spend a considerable amount of time daily interacting with screens; 6.5 hours on average, although that figure is more like 8.5 hours when simultaneous sources, such as cell phones and computers, are taken into account.
- A disadvantage of this trend is that adolescents may impede their face-to-face social competence, interacting instead through social media. Other evidence, however, suggests that social media use may enhance certain social skills.
- Although online video games may seem isolating, interacting with other players can be socially beneficial, and even violent video games may foster the development of cognitive and perceptual skills.
