The uncertainty around Iran war is becoming unbearable.
The internet blackout exacerbates an already unsettling situation.
Can barely reach my family.
I left Iran in late January and engaging in science has kept me sane so far.
New preprint! Where we used multiplayer games to track brain activity underlying the sustained intergroup bias. Led by @oritn.bsky.social . "Group-dependent learning and decision neural signals underlie the persistence of intergroup bias" doi.org/10.31234/osf... ๐
Congrats!
Haha! wish you a speedy recovery Micah.
You're a scientist I look up to!
Defended my PhD thesis last week and passed ๐๐ฅณ
It took 5 hours but flew by thanks to the engaging discussions.
Grateful to my supervisors who made the past three years fun!
Will continue as postdoc in France with Prof. Jean-Claude Dreher.
Psyched!
๐ง Our new preprint is out on PsyArXiv!
We study how getting more feedback (seeing what you could have earned) and facing gains vs losses change the way people choose between risky and safe options.

I once saw a (very interesting) talk about sleep in which the speaker started by saying that we don't really know how to define sleep, and then proceeded to operationalize sleep in flies as basically periods when they are still for a long time. This got me thinking...
Can't wait to read this!
New in TiCS w @dgrand.bsky.social @gordpennycook.bsky.social
Itโs been ~10yrs since misinfo research exploded but our paradigms are stuck in the post-2016 โfake newsโ model
Time for new approaches:
o True/False โ Content that misleads
o Belief โ Behavior
o Eval interventions in ambiguous settings
Need sources on the best practices for fMRI analysis.
Any suggestions?
Need to establish good habits right off the bat!

Interesting!
I wonder if this effect is weaker in people high on Agreeableness/empathy.

AI performance is known to scale with logarithm of sample size (Kaplan 2020), but in many domains, sample size can be # participants or # measurements...

Modern theories of emotion (especially โinteroceptive inferenceโ) often cite William James as a key inspiration. But what did James actually say about emotion, and is it supported by the data? Hereโs a brief look at the core arguments and classic evidence. ๐งต
Naturalistic study done right!
Is risk-taking shaped by decision-making or by learning? In new work, we show that in experience-based risk-taking, very little variance is explained by decision-making (top), but a lot is explained by learning (bottom). www.nature.com/articles/s41...
Yeah i had read the preprint too ha!
Such a great opportunity! but I can't apply because Trump wouldn't give a visa to an Iranian *sighs*
Yeah, shouldn't be all glass-empty ha! Your paper reminded me of this paper, which arrives at similar conclusions elifesciences.org/articles/754...
As much as i love computational modelling, the fact that conceptually similar parameters do not generalise across task contexts is a bit disappointing.
Excellent paper btw!

๐จNew preprint! WHEN should we plan toward a goal? Most research focuses on how and where to plan, but the timing of planning initiation has been overlooked. We show humans leverage a cognitive map - called model-based meta-control - to learn when to deploy a plan.

I am delighted to announce registration and abstract submission is open for "The Mechanistic Basis of Foraging 2025" to be held at the Edgbaston Park Hotel, University of Birmingham, UK on 3-5th November 2025. uobevents.eventsair.com/the-mechanis...
We are looking for a post-doc (3 yrs) to lead neuroimaging experiments (using fMRI & EEG) investigating the multimodal basis of material perception

If there was ever a moment where useful idiots who claim that misinformation isn't a clear concept, harms few, & is not widespread, have to come to terms with how their rhetoric is being co-opted by right-wing climate denial think thanks, this is THAT moment. The tobacco playbook - as predicted.
I'm very excited that this is out as preprint. In this study, 370 participants completed up to 30 runs of reward learning. We see that BMI and and Binge eating are associated with distinct RL patterns. Includes hierarchical models using Stan (+ many hours of sampling) and MRI data of an effort task
Will be at the SBDM conference next week in Lyon.
But lost all the excitement because of Israel's attack on my home country Iran.
Now I'm all worried.
If you're a grad student or an undergrad interested in research I need to you listen to me very carefully.
You cannot learn to write good research papers if you do not read good research papers.
Stop asking LLMs to summarize papers for you.

We introduce the idea of "importance" in terms of the extent to which a region's signals steer/contribute to brain dynamics as a function of brain state.
