New computational work: It's OK to stereotype people (well, a bit!), as long as we *then learn efficiently*. And 5HT may help the latter! https://t.co/sfQQHN7z7x Here is a pictorial summary:

📜 New work from us! (me, @vaughanbell, Quinton Deeley, Mitul Mehta and @mmoutou)

**D2/D3 dopamine supports the precision of mental state inferences and self-relevance of joint social outcomes**

Data, scripts and models are free and open!

I’ve also built an interactive model for you to live simulate data (click the badge in the GitHub) 👇👇

Our review on Felt Presence is now available online @thelancet Psychiatry 🎉🎉 with Cherise Rosen, Tatiana Baxter, Sohee Park, Peter Brugger & @Aldersonday

This is still a very under-researched phenomenon, despite it being reported across multiple diagnoses -

We dig into the phenomenology, philosophy, measurement, context, and theoretical and experimental basis of this fascinating experience 👥

Yesterday I finished my postgrad/staff workshop series on R, tidyverse and open-source coding Royal Holloway, University of London -

All the resources are online for anyone who wants to use them 🧑‍💻

Next up: data viz competition! 🎨

Going back to paper exams seems like a bad solution to me. Why don’t we treat this tech as we do a calculator, and let students focus on the quality of their arguments? Shunning it will just handicap the clever use of a potentially v supportive resource

New preprint from me Jonas Haslbeck, Cherise Rosen, and Martin Harrow:

"Modelling the Longitudinal Dynamics of Paranoia in Psychosis: A Temporal Network Analysis Over 20 Years"

Preprint 🔗: https://www.medrxiv.org/content/10.1101/2023.01.06.23284268v2

Data & code 🌐: https://github.com/josephmbarnby/ParanoiaLongitudinalNetworkAnalysis

To work a more complete formal theory of paranoia we develop a model of the temporal course of paranoia's relationship with other delusional themes in psychosis, and paranoia's relation to social context over two decades:

Our paper is now out in @TrendsCognSci 📜🎉

'Formalising social representation to explain psychiatric symptoms'

https://www.sciencedirect.com/science/article/pii/S1364661322003217

from me, Peter Dayan, and @vaughanbell

We review current formal models of social cognition, grouped by the depth of mentalisation they address 👥

We outline how this scientific framework can be used as a foundation to build better theories of social alterations in psychiatric disorders 🔨🔩

@TrendsCognSci @vaughanbell

It was a great pleasure to write this with Vaughan and Peter. Massive thanks to @mmoutou and Quentin Huys their comments and insight on an earlier version.

@Aldersonday https://twitodon.com/ I found these sort of tools pretty useful - you can convert all your contacts who were on twitter into who you follow here.

@Aldersonday it’s like twitter but with less chaos. Although I did enjoy a bit of the chaos.

Lol wut? 🫠 spotted in Shepherds Bush, London
