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

It’s been ~10yrs since misinfo research exploded but our paradigms are stuck in the post-2016 “fake news” model

Time for new approaches:
o True/False → Content that misleads
o Belief → 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.

Modern theories of emotion (especially “interoceptive inference”) often cite William James as a key inspiration. But what did James actually say about emotion, and is it supported by the data? Here’s a brief look at the core arguments and classic evidence. 🧵

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!

Meta‐Analysis Reveals That Explore–Exploit Decisions Are Dissociable by Activation in the Dorsal Lateral Prefrontal Cortex, Anterior Insula, and Dorsal Anterior Cingulate Cortex We conducted a coordinate-based meta-analysis (N = 23 studies) where we found activation in the dorsal lateral prefrontal cortex, anterior insula, and anterior cingulate cortex during exploration ver...

🚨New 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.

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.

🚨Preprint update!🚨

Are Large Language Models (LLMs) conscious? 🧠💻
Most say: only if they replicate the brain's computations.
But we propose a shift: consciousness should be inferred from their behavior.

Why I value peer review Nature Human Behaviour - Patricia Lockwood discusses why she values peer review and participating in the peer review process, despite some of the challenges.

Why I value peer review - new World View in @naturehumbehav.bsky.social tinyurl.com/4w5795ua I discuss why peer review is still important and useful despite some of the challenges, and reflect on some personal peer review experiences. Interested to hear what others think about peer review 🙂.

From partisan news to algorithmically curated content, we constantly receive biased misinformation. With biased input, can our beliefs be accurate?

Turns out, biased misinformation distorts our beliefs! 👇🧵 1/13

Turning papers into audio books actually works.
Been listening to a lotta papers while working out

Distorted learning from local metacognition supports transdiagnostic underconfidence - Nature Communications Individuals with symptoms of anxiety and depression exhibit persistent underconfidence. Here, the authors show that distortions in learning from local metacognition can explain how underconfidence is ...

Excited to see this now out in the world!

We identify a computational basis for how persistent underconfidence is maintained in the face of intact performance, finding that it is grounded in impaired updating of global self-beliefs from local metacognition
