Are smartphones stressful for adolescents? 🤔 Using experience sampling and smartphone trace data, we found that for ~80% adolescents, screen time is neither stress‑inducing nor stress‑buffering. For ~20%, smartphone use is stress‑inducing, but usage patterns matter ⭐ doi.org/10.1177/1461...

Excited to share our new @nature.com paper: 👉 www.nature.com/articles/s41... 500+ re-analyses show that results in social and behavioural science often depend on analysts’ choices, highlighting challenges for #robustness. Really proud and excited to be a co-author of this massive collaboration! 🚀

What drives support for violent extremism? In our new paper in PNAS (58 countries; N > 18,000), we show it’s not one mindset: 👉 Defensive (protect the ingroup) 👉 Offensive (seek dominance) Defensive motives are more common—but only offensive ones track societal violence. doi.org/10.1073/pnas...

Our new paper on the paradox of acceptance. Acceptance is central in ACT, but our longitudinal data show nuance: 👉 Lower depression across individuals 👉 But increases in acceptance can precede higher depression Not all acceptance is the same. doi.org/10.1002/jclp... #Psychology #MentalHealth #ACT

🧠 New preprint! We study reaction time modeling in self-report surveys across online vs. lab administration and single- vs. multiple-item formats, and complement RTs with eye-tracking and heart-rate measures to capture response processes. osf.io/preprints/ps... #Psychometrics #ReactionTimes

🚨 New preprint! We reviewed 263 studies on racial & ethnic prejudice measures. Most are psychometrically weak and conceptually narrow. Only 4% meet high-quality standards. We call for rigorous, theory-driven, culturally sensitive tools. 📖 osf.io/xwbyz_v1 #PrejudiceResearch #SocialPsychology

Our article on how news credibility on social network sites is (not) influenced by trust in the media, trust in friends, and their synergistic effect is now published at @ijoc-usc.bsky.social. Many thanks to @davidlacko.bsky.social and Jakub Macek. ijoc.org/index.php/ij...
