A new version of rtdists is now on CRAN: cran.r-project.org/package=rtdi... Big thanks to @kiante.bsky.social who added a new distribution, the racing diffusion model, fixed a number of long-standing bugs, and increased the speed of the diffusion model. All news: cran.r-project.org/web/packages...

How can we design experiments that make computational models disagree? One section of our new @natrevneuro.nature.com Review with @kriegeskorte.bsky.social and @heikoschuett.bsky.social examines studies that used stimulus sets designed to elicit distinct predictions from competing models. 1/16

You'd think people prefer the simplest explanation of an uncertain world — Occam's razor. Our data says no, across 2 modalities, 2 tasks, 8 experiments: people often perceive illusory structure that isn't there and prefer moderate complexity. Out now in Nature Comms! www.nature.com/articles/s41...

Fascinating and important. Including the provocative finding “What we believe about our bodily sensing may have little to do with how we actually sense it.” A place where subject report diverges (read the thread). Congrats to this team!!

Sensing your body (‘Interoception’) is everywhere in theories of mental health. But when we tested how well hundreds of people sensed their heart and lungs, the link to symptoms was almost nowhere to be found. 💣 🚨New @natmentalhealth.nature.com paper 🚨🎉 asks why 🧵 www.nature.com/articles/s44...

My new article on remembering as inverse causal inference has been published, and the first 50 downloads are free here: www.tandfonline.com/eprint/YEHFQ...

Remembering as inverse causal inference

The causalism/simulationism debate has become central in contemporary philosophy of memory. Recently, however, I have suggested that the debate is largely ill-construed and have offered instead a p...

In a new preprint, @keisukefukuda.bsky.social and I investigated stimulus-specific memorability with ROC analysis. We find that the variability of latent memory effects (familiarity) caused by individual memory items across people is a game-changing dimension of memorability osf.io/c62an/files/...

We don’t always know what problems are hard for LLMs. So devs evaluate on tasks HUMANS find hard or on broad benchmarks. What if we could instead anticipate which scenarios a model will fail on—all without evaluating specific input examples? 🧵NEW PAPER by @jenniferlumeng.bsky.social

Attention operates in a changing world, so attentional priority maps must likewise be dynamic. Our (Sage Boettcher, @visualattentionlab.bsky.social, @gwenlliams.bsky.social, Nir Shalev) TiCS paper argues this and propose key questions for future work hoping to account for dynamic priority maps.

Making time for a dynamic attentional priority map

Attentional priority is typically conceived as a static spatial map, despite attention operating in a continuously changing world. We propose a dynami…

Thanks Dr Deborah Talmi @dtalmi.bsky.social @campsydept.bsky.social for such an interesting talk on Bayesian modelling of subjective pain experiences. Nice to see the integration of basic and clinical science. 🧪

In this essay I try to articulate some thoughts about how meaning can arise in symbolic systems without external referents. The core idea: "A mathematical object is what it does inside a system of relations and operations" venpopov.com/posts/2026/s...

I met @russpoldrack.org after this effort and before I knew this particular story. I was blown away when I first read about it. Some scientific efforts “expand the domain of the understandable”. This was one of them. So great to see it profiled by @thetransmitter.bsky.social!

Really thrilled that this paper led by @neurozz.bsky.social is now published in its final version in @elife.bsky.social!! This is a memory-focused (as opposed to RL-focused) account of the detailed characteristics of forward and backward awake and sleep replay! elifesciences.org/articles/99931

A unifying account of replay as context-driven memory reactivation

A context-driven memory model simulates a wide range of characteristics of waking and sleeping hippocampal replay, providing a new account of how and why replay occurs.

When are impossibility proofs misleading? In infinitefaculty.substack.com/p/be-wary-of..., I discuss a common issue I see: proofs that are logically valid, but where the underlying assumptions are unjustified. I discuss ‘proofs’ that cognition cannot be tractably learned, and that LMs are 1/

Be wary of assumptions in impossibility arguments

A proof is only as good as its assumptions
