Children are starting on digital devices at ever younger ages, and opinions on the effects of children's digital-media habits are deeply polarised.(两极分化的).
Jean Twenge, a psychology professor, thinks excessive use of the internet and social media makes children lonely and depressed and poses serious risks to their physical and particularly their mental health, sometimes to the point of driving them to suicide.
However, Daniel Kardefelt-Winther of the Innocenti research office of Unicef examined various evidence and found less cause for alarm than is often suggested. Most of the studies he examined seem to show that the technology helps children stay in touch with their friends and make new ones.
The relationship between the use of digital technology and children's mental health, broadly speaking, appears to be u-shaped. Researchers have found that moderate use is beneficial, whereas either no use at all or extreme use could be harmful.
What worries some experts more is that screens are becoming part of the middle-class armoury(武器) for perpetuating(巩固) social advantage. Children from well-off homes are enrolled in private classes to learn skills like "How to be a YouTuber", which poorer parents cannot afford.
