Extreme-Value Signal Detection Theory for RecognitionMemory: The Parametric Road Not Taken
Signal Detection Theory has long served as a cornerstone of psychological research, particularly in recognition memory. Yet its conventional application hinges almost exclusively on the Gaussian…

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...

Next Wednesday Dec 3rd we are happy to host Prof. @miroslavsirota.bsky.social to tell us how utility-based signal detection theory can inform us of the cognitive mechanisms for (over)use of antiobiotics. Full details on our website (surl.li/mqtofs). All welcome, in person with Prof. Sirota!

Time effects on working memory and long-term memory, are they similar or different? Our work with Alessandra Souza and Klaus Oberauer here.
Memory researchers have known this: If we leave more free time between one study item and the next, memory is better. This is true for WM and LTM - but is it so for the same reason? Probably not. If you want to know more, have a look at our new paper in JEP:General: psycnet.apa.org/record/2026-...

Tfw you're reading about Maurice Hilleman, who developed 40 vaccines in his lifetime, and his work ethic
![“I ever caught anybody delaying a set of tests because [results] might come out on a weekend, it would be grounds for dismissal. You can imagine how that went over. They all had wives and that sort of thing. Now Merck tells [employees] that they don’t need to put in any extra time and that you have to balance your life. And that you have to have enjoyment with your job; [that way] you can do a better job and have fun. It’s all just a pile of shit. What the company should be doing is kicking ass. But that’s from the old school. I was told that I had a very unusual management style.”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:73aicoale2mqwrap63rdzwep/bafkreihgtvwhkkkznw3qtlbbaproublfryobx6f2ic5fwy7ptj6ufmryc4@jpeg)

A few thoughts on alcohol duty ahead of the budget (and an excuse to update some old graphs).
These two show the important of accounting for inflation - in cash terms alcohol duty rates are higher than ever before, but in real terms they are at historically low levels.

I remember reading a blog post somewhat recently on here arguing that for open science practices every effort counts. So we should not expect every paper to fulfil all open science criteria immediately but researcher should start by making their data open, then their code, etc. Anyone has a link?
