The impact of screen time on Children: insights from Michel Desmurget's "Screen Damage"


A few days ago, I learned about "Screen Damage: The Dangers of Digital Media for Children" by Michel Desmurget, originally published in 2019. Desmurget is a French researcher and writer specializing in cognitive neuroscience, and his work is based on extensive research into the effects of screen time on children.

Desmurget’s findings are not surprising: heavy screen usage leads to poor academic performance. However, he emphasizes that the negative impacts are even more pervasive and extensive, affecting children's cognitive, emotional, physical, and social development.

Children primarily use electronic devices for watching videos, playing games, and engaging with social media. While schools also use these devices for learning and testing, the initial educational intentions of teachers and parents often give way to what Desmurget calls an “orgy of recreational usage.”

Desmurget argues that time spent with screens at an early age is essentially “stolen time” from children's normal development. Early cognitive development is very crucial and depends heavily on the malleability of young brains. However, this period of brain plasticity has an expiration date. “Once closed, they can no longer be resuscitated. What has been spoiled is forever lost,” he warns.

To summarize the harms caused by electronic screens, Desmurget identifies five major areas of damage:

  1. A lack of human communication and companionship
  2. Negative impacts on the development of language and IQ
  3. Difficulty concentrating due to the distracting nature of electronic devices
  4. Significant decreases in academic performance
  5. Health issues, particularly related to sleep disorders and prolonged sitting

These damages are not limited to children but apply to people of all ages. Due to the permanent harm electronic devices can cause, Desmurget concludes that, under no circumstances or for any reason, should children aged 6 and under be exposed to electronic screens.

A Chinese saying goes, 少壮不努力,老大徒伤悲, meaning: if one does not work hard when young, one will regret it when old. It emphasizes the importance of making the most of one's early formative years, aligning well with the idea that excessive screen time can irreversibly harm children's development and lead to long-term regret.

In a world increasingly dominated by digital media and electronic devices, Desmurget's research serves as a serious reminder of the importance of protecting young minds from the permanent detrimental effects of excessive screen time. Parents, educators, and policymakers must take these findings seriously to ensure that children's development is not compromised by the very tools meant to aid their education and entertainment.

The importance of preparation: a story of pursuing and giving up dreams

A friend of mine in Chicago shared her daughter's journey with me. Her daughter was a high achiever in high school and planned to go to medical school after college, so she majored in biology. However, her true passion had always been photography since her high school days. After college, she decided to take a gap year to focus on photography.

During this time, she kept delaying taking the MCAT and applying for medical school. Eventually, she declared that she no longer wanted to pursue medicine and instead wanted to make a living as a freelance photographer.

A few years passed without enough progress in her photography career to encourage her to continue. Approaching her 30s, she started law school in the fall of 2022.

I thought going to medical school might not have been something she would enjoy, which is why she kept delaying the process. When she decided to follow the photography path, I applauded her courage. However, I felt a tinge of sadness when she turned to law school because I knew it wasn't her first choice—perhaps it was her last resort.

I think there's something she missed before embarking on the uncharted path of becoming a photographer: preparation.

There is a Chinese saying "不打无准备之仗" (bù dǎ wú zhǔnbèi zhī zhàng), meaning "Do not fight a battle without preparation." It emphasizes the importance of thorough preparation before engaging in any significant endeavor or challenge.

Though I've never been in her position, I know making a living as a photographer involves much more than just taking pictures. It is a business of making money out of your own work.

  1. Make a Business Plan: No plan means planning to fail.
  2. Continuous Learning: Keep honing skills as a photographer.
  3. Manage Everything: In the beginning, it's a one-person show, from marketing to networking.
  4. Seek Mentorship: Proactively reach out to famous photographers you admire and ask for guidance.
  5. Network: Join local and online communities of photographers.
  6. Active Marketing: Be active on all social media platforms.

In a word, she needs to think it through and thoroughly prepare for the challenges on the path to making photography profitable. I have no doubt she wouldn't have quit had she been better prepared.

While it's admirable to follow one's passion and take the path less traveled, the story of my friend's daughter underscores the importance of preparation in turning dreams into reality. With proper planning and dedication, the path to success, no matter how unconventional, can be managed more effectively and with greater confidence and better results.

Different paths to success: treasure hunts vs jigsaw puzzles

There are so many things that I'd like to write about today. First, I saw this post by an acquaintance of mine who just became a full professor, "I’ve reached the finish line! No more assisting or associating with professors—I am one! A FULL professor! It’s been a tough but incredibly rewarding journey."

Immediately, this poem surfaces in my head, "春风得意马蹄疾,一日看尽长安花" (chūn fēng dé yì mǎ tí jí, yī rì kàn jǐn cháng ān huā), meaning: riding the galloping horse swiftly with spring breeze at my back, I see all the flowers of Chang'an in one single day. The poet of the Tang Dynasty wrote these lines after passing the Imperial Examination. The poem captures the joy, excitement, and exhilaration of achieving success, like riding a galloping horse through the blooming city of Chang'an and enjoying all its beauty in one single day.

Second, yesterday I was going through the notes that I took a few years ago when we interviewed some high achievers among high school and college students.

During the interview of one high achiever who ended up at MIT, a parent asked, "What if you don't know what you should do now?" The interviewee answered, "At this point, I don't know what I want to do in the future. There are still plenty of questions for me to sort out. I think I will be okay if I keep doing what I'm interested in. I might not have the direct route to what I want to do, but the experience that I have on the way is going to be valuable and useful, even if I am not doing what I initially set out to do. What I learn in the process is so valuable to me."

This is perfectly alright if you see life as entering a treasure hunt journey, trying different things and enjoying the process of trying because you don't know exactly what you want to do with your life.

But if you read biographies of famous people, you will notice one thing in common: most of them did not necessarily start from an advantageous position in life; rather, they all began earlier. They all figured out what they wanted to do with their lives at a very young age. I also think of my son who, still a teenager, figured out what he wanted to pursue in his career.

If you have a clear idea of what that final picture looks like and understand where to find the pieces, the rest of the task is like solving a jigsaw puzzle. Every piece helps you get closer to the whole picture. On the other hand, with the treasure hunt, you might spend more time trying different routes.

Time is the biggest asset for young people, especially during their 20s, the most energetic decade of their life. Trying different treasure hunt routes might not be as time efficient as adding jigsaw pieces to your whole picture.

Finally, whether you approach your career and life as a treasure hunt or a jigsaw puzzle, the key is to remain dedicated, curious, and open to learning. Each path has its own rewards and challenges, and having a clear goal and understanding your journey are important toward achieving your own version of success.

Days of Distraction by a young Asian American author

Last week, while staying at my son's place, I read Days of Distraction: A Novel (2020) by Alexandra Chang, a young Chinese American writer from San Francisco who earned her MFA in 2018. The novel reads like a fictionalized autobiography of her young life.

The story follows a young Chinese American woman, the narrator, meeting the emotional and psychological challenges of her relationship with a white man. It delves into timeless themes such as family immigration history, identity, racial and gender stereotypes, interracial relationships, and cultural differences.

As a tech journalist covering Silicon Valley, the narrator feels dissatisfied with her job and stagnant in her career. She decides to accompany her boyfriend to New York, where he will pursue graduate school. Amidst this move, she finds herself away from her family, friends, and familiar surroundings, just two of them, an Asian girl and a white man, keenly aware of the differences in their life experiences and racial and cultural backgrounds.

The novel's fractured structure, with its narrative jumping between past and present, research and reflection, alternating between narrative and silent introspection, adds a dramatic layer to the storytelling. This technique perhaps mirrors the author's intent to evoke the complexities of her personal reflection and fictional exploration of her own life experiences.

As the narrator struggles with the tensions between her Chinese American heritage past and her present romance with a white boyfriend, Chang experiments freely with new creative format and invites readers to appreciate her creation and contemplate the universal themes of belonging, identity, personal growth, cultural and racial differences.

To me, the best part of the book is the sense that Chang is experimenting with the book's structure and form without any restrictions, creating a unique reading experience.

Finally, while the novel receives high ratings from some, it may not resonate with every reader. Our reading experience is highly subjective, influenced by our preferences, expectations, and background. It is perfectly valid if, like me, you find the book didn't meet your expectations.

Reflections on oath-taking experience and immigration

Yesterday, something interesting happened at the oath-taking ceremony. First, applicants were asked questions like, "Are you affiliated with any terrorist or communist organization?"

Secondly, among the 60-plus new citizens, the majority appeared to hail from south of the border, with few Asians and almost no white individuals. This demographic distribution may reflect broader trends in the U.S. immigration patterns, signaling a notable shift from historically Europe to today's South and Central America.

Moreover, the primary drivers of human migration remain the same: economic and social factors, elucidating the greater influx from the poor South and Central America compared to the rich countries in Europe.

During my stay at my son's home this week, I delved into the novel How Much of These Hills Is Gold by C Pam Zhang. The narrative weaves a tale of two orphaned Chinese-American girls amidst the 1840s Gold Rush, blending fiction with a realistic historical backdrop.

Both the novel and the oath-taking experience resonate deeply with the immigrant journey. They evoke familiar themes in the lives of today's immigrants: being drawn to this land by the promise of prosperity akin to the gold mountain, the ache of homesickness, encounters with diverse forms of discrimination, maintaining cultural heritage from their homeland, and the perennial question, “What makes a home a home?” in a land where they both grow up and feel estranged.

A Chinese proverb aptly captures the immigrant experience: 背井离乡 (bèi jǐng lí xiāng), leave one's home village, evoking the sense of leaving behind one's home in search for a better life, facing hardships, and longing for a new home. This encapsulates the emotional journey endured by generations of immigrants on this land.

The quest for a better life has historically driven migration, still persisting as a powerful motivation today. Yet, this journey is often marked by profound and often unexpected challenges.

As the country embraces new citizens, let us honor and listen to their immigration stories, especially today, celebrating their enduring spirit in the pursuit of a place they can call home.
