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.
Couldn't agree more :)

Finally out in Psychological Review (psycnet.apa.org/doi/10.1037/...), our update to Signal Detection Theory. We show that contrary to the prevailing Gaussian assumption, evidence distributions in recognition memory are likely minimum extreme Gumbel!
Honey, we fixed Signal Detection Theory (SDT)! In this preprint, Constantin Meyer-Grant, David Kellen, Sam Harding, and I critically evaluate the (unequal-variance) Gaussian SDT model in recognition memory and pursue the Gumbel-min model as a principled alternative: doi.org/10.31234/osf... 🧵
Finally, our paper is out! Together with @aliciafrancomnez.bsky.social, Javier Revuelta, and @mavadillo.bsky.social, we extend hierarchical factor models for skewed RTs and task validation, now in Psychological Methods: doi.org/10.1037/met0... Let me briefly explain what we did and why it matters!

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!

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.

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.
