In a new book, “Irresistible: The Rise of Addictive Technology and the Business of Keeping Us Hooked,” social psychologist Adam Alter warns that many of us—youngsters, teenagers, adults—are addicted to modern digital products. Not figuratively（adv. 比喻地；象征性地）, but literally addicted.

Q: What makes you think that people have become addicted to digital devices and social media?
问：是什么让你觉得人们已经对电子设备和社交媒体上瘾？
A: In the past, we thought of addiction as mostly related to chemical substances: heroin, cocaine, nicotine. Today, we have this phenomenon of behavioral addictions where, one tech industry leader told me, people are spending nearly three hours a day tethered（拴住） to their cellphones. Where teenage boys sometimes spend weeks alone in their rooms playing video games. Where Snapchat will boast that its youthful users open their app more than 18 times a day.

Q: How do you define “addiction?”
