🧠 How do transformers learn relational reasoning? We trained small transformers on transitive inference (if A>B and B>C, then A>C) and discovered striking differences between learning paradigms. Our latest work reveals when and why AI systems generalize beyond training data 🤖

“The gender-equality paradox entails that countries with more equality have larger gender differences in behavior. Positive associations between equality & gender differences disappear or reverse when accounting for cultural clusters of countries. The paradox appears to be a methodological artifact”
Simpson’s gender-equality paradox | PNAS
Several cross-country examinations have found larger gender differences in Western countries. More recently, it has been argued, from an evolutiona...

How do cognitive maps fail? And how can this help us understand/treat psychosis? My lab at @oxexppsy.bsky.social is hiring a Postdoc tinyurl.com/2p935hhz and RA tinyurl.com/3myfpb78 to answer these questions in mouse models. Here's why you might want to join: 🧵

New paper from our lab now in @nature.com . We show that our brains use basis functions or "building blocks" to navigate social interactions. Rather than tracking every individual separately, social information is compressed into patterns that can be flexibly combined. www.nature.com/articles/s41...
Basis functions for complex social decisions in dorsomedial frontal cortex - Nature
A study combining group decision-making tasks with fMRI shows that the brain’s dorsomedial prefrontal cortex uses basis functions, similar to those in the visual, motor and spatial domains, to re...

Comment on our recent paper challenging the link between MMN dysfunction and positive symptoms: www.sciencedirect.com/science/arti... Thanks @mattnour.bsky.social I may have missed it but cognitive map dysfunction is also unrelated to positive symptoms so far?

Our symposium on structure knowledge biases in psychopathology was accepted at #CPConf2025! with @mattnour.bsky.social @mgarvert.bsky.social @carocharp.bsky.social Talks will span social learning, inductive inference in planning, language representation & map-based generalization. Can't wait!
Curious to see how they plan to anonymise our NHS data for training ML models. I personally wouldn’t know how to start doing that www.theguardian.com/politics/202...
Very excited to lead this work at @ox.ac.uk. We're developing computational tools for neuroimaging data and naturalistic behaviour, some based on LLMs. We hope these will yield new insights into the mechanisms of CNS drugs, neurobiology of psychosis, and human cognition more broadly.

Excellent review paper (by @rob-mccutcheon.bsky.social @mattnour.bsky.social & others) Clearly lays out the historical challenges and future frameworks to guide drug development in psychiatry. www.biologicalpsychiatryjournal.com/article/S000...
Psychotropic Taxonomies: Constructing a Therapeutic Framework for Psychiatry
Pharmacological interventions are a cornerstone of psychiatric practice. The taxonomies used to classify these interventions influence the treatment and interpretation of psychiatric symptoms. Disease-based classification systems (e.g., ‘antidepressant’ and ‘antipsychotic’) do not reflect the fact that psychotropic agents are used across diagnostic categories, nor account for the dimensional nature of both the psychopathology and biology of psychiatric illnesses.In this review we discuss the history of psychotropic drug taxonomies and their influence on both clinical practice and drug development.

In principle, ~10^15 bits needed to specify all connections in brain assuming any wiring diagram is possible In practice, much less needed. Indeed innate behaviors must fit in the genome (~10^9 bits in humans) So: GPT4 has enough parameters. Just not the right ones www.pnas.org/doi/10.1073/...

There's a movement in neuroscience suggesting we should be pursuing bigger bets with larger teams. I think there's a case for doing a bit of this, but I think it's a bad idea to prioritise it for two reasons, and a good case for saying we should be moving in the exact opposite direction. 🧠🧪
