New preprint! 📚📱 osf.io/3kpf9_v1 Did you ever stand in a bookshop and wondered who tends to buy self-help books, and whether people who buy them actually change? Here, we looked at these questions for self-help products more generally (also apps, seminars, etc.), which are a rapidly (1/3)

New preprint! Many claim that first sex is a huge risk for teens. We tested that claim in a large, nationally representative German sample. Core question: Do first sexual experiences harm adolescents, or do they reflect prior well-being? osf.io/preprints/ps...

We are conducting a meta-analysis on personal and contextual predictors of solitude. We're looking for unpublished research such as theses, unpublished manuscripts, conference submissions etc. Full call for data: tinyurl.com/4hur45cw Please reskeet, or message me if you know unpublished research!

New preprint! Ever heard that personality doesn't change? Do you believe that? (you shouldn't) Using data from an online survey (n = 887) & eight longitudinal datasets (n = 166,971), we compared perceived vs. actual lifespan changes in personality and 20+ individual differences (1/8) osf.io/ytmxp

Meta analysis in press at JPSP: personality traits are related to volunteering and charitable giving. Which have the biggest effects? See below (hint: they start with vowels) @wiebkeb.bsky.social osf.io/preprints/ps...

Ever wondered whether our personality influences our first sexual milestone? 🍒 We explored how the Big Five traits affect the timing of first sexual experiences — and how these, in turn, shape personality traits over time. Check out our preprint: doi.org/10.31234/osf... #PersonalityPsych

How should we score divergent thinking tasks to best assess the ability to generate creative ideas? 🤔 It’s a big question in creativity research, so we systematically compared different scoring approaches to evaluate their psychometric quality. Check out our findings! doi.org/10.1002/jocb...

Can people intentionally change their personality? Happy to share that our review on volitional personality change research has now been published at Nature Communications. Open-Access-Link: doi.org/10.1038/s442...

New preprint 🤗 Life events are a commonly studied environmental factor believed to influence normal-range personality development (such as the Big Five), but how well does this extend to features of personality pathology? (1/7) t.co/PyPkEUATP3

Made my conference debut talking about #sexualdebut and its relationship with #personalitytraits. Like many others, I did not make it to the @dgps.bsky.social #DGPs2024 congress @univie.ac.at, but still enjoyed my digital experience a lot!

Already excited for the @dgps.bsky.social congress next week in Vienna? 🇦🇹 If you're around on Wed. 9:30, we'd love to see you in our symposium on social drivers of personality change w/ Manon van Scheppingen, Larissa Wieczorek, Eva Bleckmann, & @rosalieandrae.bsky.social (who created this graphic😊)

Excited to share that you can now read the preprint to our investigation of response aggregation methods in divergent thinking assessments: osf.io/preprints/os.... Big thanks to @srtzki.bsky.social , Boris Forthmann, and Mathias Benedek!
