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…
doi.org
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...

Policy #evaluation inherits concepts from multiple disciplines, and somewhere along the way many of them have become muddled. This blog post sketches what I think are seven of the most irritating myths.

So much of complicated statistics (latent class/profile stuff, SEM, network analysis) seems optimized for publishing in ‘top’ journals without meaningfully improving knowledge.
Some days ago a student struggling with her master’s thesis e-mailed me, asking me about partial least squares structural equation modeling. I told her I can only tell her not to do that, and then she sent more details.>

Perfect read for the end of the year. LLMs reveal what is wrong with how we evaluate science through citation metrics.
If you have to read anything about the prospect of “automating scientific discovery,” “agents for science,” or integrating LLMs into scientific pipelines, please let it be this essay by Kevin T. Baker: artificialbureaucracy.substack.com/p/context-wi...

Psychologists, what are your favorite (open) data sets for teaching multilevel modelling? I have a lot of observational examples, would love a therapy RCT with varying effects for therapists or some such.

Not just recognition responses, but also associated RTs!
And not just the semantic task, but also the structural task - where words overlap in orthography/phonology!

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-...
