A new guide for evidence accumulation models in AMPPS of @psychscience.bsky.social A must read before you start using HDDM/docker HDDM/EZ DDM/fast-dm etc, better if you read it before design experiment! journals.sagepub.com/doi/10.1177/...

Excited to share some work presented at @vssmtg.bsky.social this year #VSS2025. A great talk by Anxin Miao on a model codeveloped with @timbrady.bsky.social that bridges Bayesian and representational theories of memory, and makes parameter free predictions of visual memory biases.

New CogSci paper! In "Taking others for granted: Balancing presentational and personal goals in action selection" we propose a computational model explaining why people favour self interested behaviour when they believe others to trust them. 📃 osf.io/preprints/ps... 📎 github.com/Vbtesh/takin...

I have the same question for one of my packages: does anyone have experience with S7 in #rstats?

I wrote a thing about multivariate normal sampling in #rstats, and why you would be well-advised to prefer mvtnorm::rmvnorm() over MASS::mvrnorm() Now. Let us never speak of this again

🚨 New blog post 🚨 What does difference-in-differences have in common with Dungeons & Dragons? Answer: the willing suspension of disbelief in unprovable assumptions. Can we trust DiD? I show when we can with a new way to simulate the power of DiD. #rstats www.robertkubinec.com/post/did_dnd/

New Marie Curie call: If you recently got your PhD and are interested in working on cognitive models or computational statistics in psychology, please get in contact to discuss your plans. The department of experimental psychology at UCL is a great place for science in the heart of London.

Definitely an issue I sometimes spot in psych as well! If you want to control for higher-level characteristics, you’ll need a fixed effects model — or a multilevel model with tweaks www.statmodel.com/download/Ham...

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... 🧵

The mods of r/ChangeMyView shared the sub was the subject of a study to test the persuasiveness of LLMs & that they didn't consent. There’s a lot that went wrong, so here’s a 🧵 unpacking it, along with some ideas for how to do research with online communities ethically. tinyurl.com/59tpt988

I think this post nicely brought together a number of threads that I had seen discussed individually many times before but, well, benefit from being placed together.

How much can we trust our memories? 💭 Professor Chris Brewin (@uclpals.bsky.social) & Bernice Andrews (University of London), revisit a core experiment on false memories, and find that they’re much harder to implant in people’s minds than previously thought.

Come be my colleague at UCL. We are looking for someone working on computational approaches to cognition. In other words, for any type of cognitive modelling or mathematical psychology! #MathPsych

5 stars is better than 4 stars, but can we even define how much better it might be? Modeling ordinal outcomes like ratings is a subtle topic; fortunately I have a new chapter that dives directly into that nuance. HTML: betanalpha.github.io/assets/chapt... PDF: betanalpha.github.io/assets/chapt...

@singmann.bsky.social will be joining us at Princeton Psych tomorrow, March 25th, at 11am (EST), to talk about when we should and shouldn't be using mixed models. Zoom details in the flyer!

One of the best things you can do, imo, to improve the quality of your patient-focused research is to measure fewer things. I'd go so far as to say you really shouldn't be measuring anything about patients unless you know exactly what you are going to do with those data.
