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...

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
🚨 New Preprint!
🧠 We gave an AI model one simple rule: rearrange your neurons so that nearby ones respond alike. We never told it what a face, a voice, or a sentence was.
It grew brain-like maps for all three anyway. 🧵👇

Natural behavior unfolds as a continuous stream of actions. Because these actions often occur in rapid succession, the brain must prepare multiple future actions while the current action is being executed. Our TICS piece explores how this works.

How do human minds make sense of big, messy problems? 😵💫🌀
How do we distill complexity into something simple enough to solve? 🤔💡
We’ll be tackling these questions (and more!) at two workshops on task representations, abstractions, and construals #CogSci2026 #CCN2026 🧵

Making time for a dynamic attentional priority map

Here's a bit of unusual work on error processing and error awareness from our lab, which we've been working on off and on for around eight years: www.biologicalpsychiatrycnni.org/article/S245...
Details in thread
Attentional priority is typically conceived as a static spatial map, despite attention
operating in a continuously changing world. We propose a dynamic priority map and
outline the core demands and ke...
Conscious error detection is accompanied by error-related changes in phasic autonomic
activity. This autonomic response is diminished in older age – accompanied by impairments
in the conscious detecti...
Why does dopamine ramp up during approach to predictable rewards?
In this preprint with Luke Priestley, we explore the idea that dopamine ramps occur when reward predictions inferred using a world-model are used to train striatal cached values.
I-75 Scientist
Midbrain dopamine neurons are thought to implement a temporal difference (TD) reward prediction error (RPE) that updates cached values stored in striatum. This has been challenged by evidence that dop...
