“Have Smartphones Destroyed a Generation?” doesn’t offer a definitive answer to the question of its title, but the evidence that its author, Jean M. Twenge, identifies linking depression to smartphone use leads her to recommend that parents limit their teenagers’ screen time. Twenge, a professor of psychology at San Diego State University, who has studied generational differences for twenty-five years, has observed a significant shift in teenagers’ behaviors and emotional states that began around 2012, the year when the proportion of Americans owning smartphones first exceeded fifty percent. Twenge’s findings present a portrait of adolescents who are psychologically more vulnerable, and whose increased vulnerability coincided with the dual rise of smartphones and social media.
For tomorrow, for their first reading assignment of the semester, my students will read Twenge’s article on paper, making notes in the margin as they read. Last week as I composed that assignment, stipulating that students print the article, I heard their voices of dissent in my head.
In the process of reading Twenge’s article, some students may decide that my requirement was reasonable. Others, perhaps most, will see it as unnecessary.
When I first read Twenge’s article a couple of weeks ago in the September issue of The Atlantic, I knew that I would ask my students to read it as well, in part to demonstrate why I limit their use of digital devices in the classroom. But I also knew that I could not in good conscience ask them to read Twenge’s words on the screen. If, as she reports, two or more hours a day on electronic devices negatively impacts mental health and sleep, it would seem nothing short of cruel irony to require my students to read Twenge’s 5,000 words online.
Twenge’s article is adapted from her forthcoming book, iGen: Why Today’s Super-Connected Kids are Growing Up Less Rebellious, More Tolerant, Less Happy–and Completely Unprepared for Adulthood–and What That Means for the Rest of Us.
