Excited to share our latest paper in which we discuss merging theory-and data- driven computational psychiatry in a large transdiagnostic cohort study (N=2400)

Thanks!
I'm heading to CNS in Vancouver! Come check out my poster Sunday morning for some fun work (🐁?)
DM me if youll be there and want to link up!
Thanks Dennis! Would love your thoughts/feedback
Thrilled that this first empirical paper out of the lab is posted, led by Sandarsh Pandey, asking:
Depression (and other internalizing disorders) involve profound changes to sense of self. How can we study these differences using rigorous decision-making methods?

If you're headed to #sas2026 next week, check out work from 3 lab members:
Friday:
* Sissi Li on expectation setting + mood in worriers (P2.C.139)
Saturday:
* Tess Gilmartin on an RL perspective on self-monitoring (P3.C.248)
* Sandarsh Pandey on capturing latent self-schemas (P3.C.251)
I'll be giving a talk in the #CNS2026 Rising Star session on Saturday. Come say hi if you're around!
Our crowdsourced megastudy comparing a diverse set of 12 single-session interventions for depression is out today in @nathumbehav.nature.com!

We also published a brief non-academic piece about the study today: theconversation.com/free-10-minu...
📢New paper out today in @cognitionjournal.bsky.social!
Does the value of an unchosen option — inferred through counterfactual reasoning — spread to related items in memory, similar to how the value of a chosen option — acquired through direct experience — does?
In short, yes!
Personalized Prediction of Momentary Affect with Passive Smartphone Sensing Data in a Clinically Heterogeneous Sample: An evaluation of machine learning and mixed effects approaches: https://osf.io/2g8dp
Changes in our feelings, or "affective surprise," may act as a learning signal that influences what we remember. Large magnitude deviations in experienced valence during encoding relate to better long-term associative memory.
🚨New pre-print🚨

What if the relationship between smartphone use and mental health depends not just on specific harmful or beneficial activities, but also on how users transition between activities?
This Wednesday February 25! Dr. Michael Treadway (Emory University) is presenting in
@motcogmeet.bsky.social series: "Effort-Based Decision-Making and Its Discontents: Precision medicine approaches for understanding the pathophysiology and treatment of motivational deficits in mental illness" 1/
The project started pre-Covid, so it’s especially exciting to finally see it in print. Huge thanks to my amazing collaborators who made this possible: Bas van Opheusden, @fredcallaway.bsky.social, @cocoscilab.bsky.social and James Hillis.

Where you look next isn’t arbitrary.
In our new paper, we model human eye movements in immersive visual search as reinforcement learning under cognitive constraints. 🧵
🚨🚨New Preprint Alert!🚨🚨

Animal learning is painfully slow (at least initially). Yet, well trained animals can learn very fast, sometimes displaying few-shot inference. How does this transition occur?
That’s awesome! Very cool and much needed
We are recruiting! Postdoctoral research fellow at www.sdn-lab.org, studying the computational & neural basis of social decision-making. Birmingham is a fantastic & affordable place to live, with one of the youngest populations in Europe & over 600 parks. Please share!

I love this. And periodically you accidentally eat a blazing wing and black out for a few minutes.
Yeah and it does seem to have the effect of making them catastrophically unforgettable
Excited to share my first PhD paper with @ashenhav.bsky.social

Seems like that might work well in a block, yet ultimately be retained better if interleaved with co-authors
Book cover. A silhouette of a person's head filled with colorful geometric shapes—perhaps symbolizing cognitive resources or deployment thereof. The style is attractive and modern, if generic. text: The Rational Use of Cognitive Resources Falk Lieder, Frederick Callaway, Thomas L. Griffithts
I'm excited to announce that I had my first (co-authored) book published today! "The Rational Use of Cognitive Resources" with Falk Lieder and Tom Griffiths (@cocoscilab.bsky.social ). You can read it for free! (see thread)
I will be hiring a full-time pre-doctoral Research Professional to work with me at Chicago Booth.
Know someone interested in studying conversation and connection? Please help spread the word!

New preprint alert🚨
We often rely on 0-10 scales to assess suicide urges in EMA and clinical settings. But we rarely ask a surprisingly important question:
What do these numbers mean?
In our new paper, we examine what these ratings mean and how consistently people use them.

So proud of @meganspurney.bsky.social and team for this exciting new paper from my lab!
Younger adolescents' working memory performance benefits more from reward than older teens and young adults.
This occurs even though all ages report similar preferences about reward value and cognitive demand.

Have you been interested in any of the set theory stuff I've been doing recently? Wondered at all how you can get in on the fun? Here's an R package @nicolasleenaerts.bsky.social and I built called 'setweaver.' This vignette should get you up and running. Yay :)
