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...

It's the 3rd of January 1939, your name is professor James Smith and you are staring at a drawing of a fish. It's not a regular fish. It is a completely impossible fish.

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.>

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.
