Leading Scholars and Their Contributions

1. Jean Twenge (San Diego State University)

   • Major Contribution: Twenge's work focuses on generational differences and how social media impacts youth mental health, especially the rise in depression and anxiety in "iGen" (those born after 1995).
   • Notable Works: iGen: Why Today's Super-Connected Kids Are Growing Up Less Rebellious, More Tolerant, Less Happy – and Completely Unprepared for Adulthood
   • Key Findings: Correlations between increased screen time and a decline in mental well-being in adolescents, with particular focus on smartphones and social media.

2. Ethan Kross (University of Michigan)

   • Major Contribution: Kross studies the emotional impact of social media on well-being, particularly Facebook use, and has investigated the phenomenon of "social comparison."
   • Notable Study: His 2013 paper in PLoS One, where he found that Facebook use is associated with declines in subjective well-being.
   • Key Findings: Highlights how passive use of social media can lead to envy and lower satisfaction with life.

3. Sarah Coyne (Brigham Young University)

   • Major Contribution: Coyne's research focuses on the nuanced effects of social media on adolescents, including positive and negative outcomes depending on how social media is used.
   • Notable Works: Research on the effects of social media on self-esteem and body image, specifically how social media impacts adolescent development over time.
   • Key Findings: Emphasizes that effects can vary widely depending on usage patterns (e.g., active vs. passive use, content consumed).

4. Andrew Przybylski (University of Oxford)

   • Major Contribution: Przybylski studies the relationship between digital media use and psychological functioning, using large datasets to address the media’s effects on children and adolescents.
   • Notable Works: Studies on "screen time" and its real effects, often challenging the concept that all screen time is inherently harmful.
   • Key Findings: Suggests that moderate levels of social media use might not be harmful and stresses the need for balanced perspectives.

5. Amy Orben (University of Cambridge)

   • Major Contribution: Orben is known for her work using robust statistical methods to study social media's impact on adolescent well-being and mental health, often finding very small or negligible effects.
   • Notable Works: Research on "Goldilocks Hypothesis" (moderate screen time being harmless).
   • Key Findings: Critiques methodological flaws in many social media studies, advocating for more accurate, transparent research.
