I'm a psychometrician in the experimental field, currently doing my PhD research on the Psychometric Properties of Experimental Tasks at the Universidad Autónoma de Madrid.

reach out if you or someone you knows wants to chat about doing some modeling together 🤓 my focus is primarily on modeling behavioral paradigms and self-report measures—either together, separately, or even longitudinally bayesianbeginnings.com/?v=2

When coding hierarchical models in Stan, I always check if I can specify a marginal likelihood to avoid sampling random intercepts or slopes. While this speeds things up and improves model comparison via LOO, it's incredible how the conditional log-likelihood naturally solves missing value problems!

SCORE, a collaboration of 865 researchers, is now released as three papers in Nature, six preprints, and a lot of data (cos.io/score/). SCORE examined repeatability of findings from the social-behavioral sciences and tested whether human and automated methods could predict replicability.

SCORE shows that there is no shortcut to producing credible research findings, and there is no single indicator of trustworthiness. Research progress depends on transparency, rigor, and establishing r...

Paper alert! 📢 We just published a Registered Report Many-Labs study! 🌍🔬 I have to highlight the massive amount of work @aliciafrancomnez.bsky.social put into leading this. I feel truly honored to be part of this team and to learn from her example of exactly how science should be done.

So happy this is finally out, almost 4 years in the making! academic.oup.com/nc/article/2... A celebration of open and collaborative science: 📜Replicating the unconscious working memory effect: a multisite Registered Report Thank you so much to the 48 coauthors of the uWM project!🇬🇦

Two years ago, I had an idea, one that evolved over time as I kept reading and learning. Today, a major first part of that idea has just become my first PhD preprint, now publicly available on PsyArxiv. Let me tell you a bit more about the story behind it... while I prepare the submission.
