Wow, the exodus from X -> Bsky is taking off like never before! So many cool new starter packs. I made one for cognitive neuroscience accounts! go.bsky.app/2n84SRM

It’s important to build communities, but this place is getting more wretched by the day. Hope to see you all on the other side.

Replying to @JacquesPesnot
@JacquesPesnot and I are very happy to share this paper. osf.io/preprints/psyarxiv/ry…. Building on work by @scychan_brains we show that human in-context and in-weight learning vary with the distributional properties of the training data in a very similar way to transformer networks.

Do humans learn like transformer networks?

Do humans learn like transformers? We trained both humans and transformer networks on a rule learning task where they had to respond to a query at the end of a sequence of symbols (the context). At...

Our paper on the Affective Gradient Hypothesis is now out on @TrendsCognSci! 🧠 ➡️sciencedirect.com/science/ar… For a short summary of how this theory originated and what it proposes, see this 🧵: xitter.cf/amitaishenhav/status/1…

I'm very excited to share a preprint from a passion project I've been working on this past year! This came out of trying to work through two puzzles that have been bothering me for a while, and which are at the core of almost everything most of us study. osf.io/preprints/psyarxiv/68…

Super excited this one is officially out! How/when can we suppress the urge to look at and attend to salient distracting information? Check out Han's thread for an explainer! "The temporal dynamics of visual attention" in JEP: General

✨Rethinking reinforcement learning: the interoceptive origins of reward doi.org/10.31234/osf.io/be6n… An honour and *absolute delight* bouncing ideas with these brilliant women: @debyeeneuro @danamsmall @rikepetzschner What are primary reward signals and where do they come from?

Before you write a review of a paper in which you say "It's mostly meh" (a direct quote), stop to consider that you might be talking to a grad student who spent years on the project and is now internalizing the social norms of their profession.

Excited that the preprint for the work from my first two years of PhD at @summerfieldlab is out! In this work, we examine the role of action prediction errors (APEs) in cognitive control: osf.io/5ezxs (1/4)

We have a new preprint with @kazuhi_s_ , Takahiro Nishio, and @BadreLab! “Practice Reshapes the Geometry and Dynamics of Task-tailored Representations.” biorxiv.org/content/10.1101/…

Practice Reshapes the Geometry and Dynamics of Task-tailored Representations

Extensive practice makes task performance more efficient and precise, leading to automaticity. However, theories of automaticity differ on which levels of task representations (e.g., low-level...

I've been recommending this review by @EgnerLab to many: nature.com/articles/s44159-0…. It's a great overview on task control research, summarizing several interesting insights! However, w/ Gesine Dreisbach and @smusslick, we disagreed with one conclusion: nature.com/articles/s44159-0… (1/7)

Also worth noting that at least 2 more papers called for similar ideas: advances.in/psychology/10.56…; sciencedirect.com/science/ar…. They make important points, but I don't see the need to abandon the trade-off idea, which as the second paper notes is likely very task-specific. (6/7)

Of course, there’s much more to unpack than 500-word commentary formats allow, and I may come across more confident on paper and tweets than I am in reality. Therefore, always happy to discuss further in a conference hall or other meeting, and learn where I might be wrong! (7/7)

Very excited to share this preprint that's been a massive labor of love and provides a new "middle way" for studying multigenerational processes that compliment the control of a lab experiment 🔬 and the real-world validity of archaeological records🦴! osf.io/preprints/psyarxiv/tz…

Need a thrilling weekend reading recommendation? I might have just the thing for you! 👉rdcu.be/dTa5D Read the final paper @NatureHumBehav and don't skip the *peer review*!😱😱😱 Thanks to my brilliant collaborators @BenediktEhinger @NassarLab and @ShenhavLab !🧡🧡🧡

You make a decision. Your brain shows signals related to the values of your options. So the brain signals must be related to your decision. Right? Wrong! It turns out there’s more and less to what we thought were decision-making signals. 🧵
