“Have smartphones destroyed a generation?” Jean Twenge – a psychology professor at San Diego State University – asked in her controversial book, iGen. In the book, she argues that those born after 1995 are facing “a mental-health crisis”, and she believes it can be linked to growing up with their noses pressed against a screen. Her newest study provides more support for that connection, showing that teens who spent more than an hour or two a day interacting with their gadgets were less happy on average than those who had more face time with others.
Twenge’s conclusions have come up against criticism in the past. Some have accused her work of oversimplifying or overlooking data that may tell a slightly different story. Twenge recognizes that her study suggests only a link between screen use and psychological well-being. A possible explanation is that kids are running to their screens to escape from the things in life that are making them unhappy. However, the surveys can’t say whether screen time directly changes teens’ mental health, the research states.
Philanthropist Melinda Gates, whose three children were also born after 1995, wrote in The Washington Post, “phones and apps aren’t good or bad by themselves, but for adolescents who don’t yet have the emotional tools to overcome life’s problems, they can aggravate the difficulties of growing up.” At the same time, she said, kids are learning on their devices and connecting in novel ways. Other studies have  explored the connection between social media and isolation and how “likes” activate the brain’s reward centre. Some analyses have found that moderate use of these technologies is not harmful in itself and can even improve children’s social skills and build emotional strength.
There is no doubt that people are spending more time on these devices and that technology is having a major impact on kids and adults alike. “These are really important devices that have changed our lives in so many ways, not just for the worse but for the better,” said Amanda Lenhart, deputy director of the Better Life Lab at New America. But the latest research “is looking straight at technology and wanting it to be the scapegoat.”
