🚨New preprint alert! 🚨
Do multimodal LLMs (VLMs) reason about high-level visual perception like humans do? We asked over 2000 human observers and 18 VLMs to describe scenes using 15 different tasks, ranging from general knowledge, affordances, affect, sensory experiences, and future prediction. 1/

Just finished my metareviews for #CogSci2026 . I've been really impressed by the quality of the reviews! Thoughtful, polite, zero AI slop. Thanks all for taking the time to read the papers and provide insightful comments.

Language, Intelligence & Thought lab is looking for a lab manager! This is a 2-year postbac position that will allow you to gain experience in human neuroscience, cognitive science, and AI research prior to applying to PhD programs.

Excited to share new work on how the brain makes social inferences from visual input! 🧠👯‍♂️
(With @lisik.bsky.social , @shariliu.bsky.social, @tianminshu.bsky.social , and Minjae Kim!) www.biorxiv.org/content/10.6...

Very cool, excited to take a look!

Looks cool Gasper! Just curious, why do you think the absence/presence of language in animals would affect their personhood / legal status?

Wohoo many congratulations!!! 🎉🎉🎉

Sure, not defending the vibe coded model; my comment was more about the tone of the conversation... If you do add your model to BrainScore, I too will appreciate an opportunity to compare the results directly (we have implemented a version of that model in our lab, but applied to a diff dataset)

We all want to understand the brain, let's help each other

Hi Nima - could you please contribute positively to the NeuroAI community by staying cordial & working to improve the field together, not tear people down? My lab has benefited from your paper, yet this kind of discourse is stalling positive change, not promoting it.

Uncovering the Role of Language in Machine Reasoning Large language models (LLMs) gain their encyclopedic knowledge and conversational tact by learning from an entire internet’s worth of human-generated text. But learning from language alone has shown d...

Our workshop on LLMs, Cognitive Science, Linguistics, and Neuroscience explored why LLM capabilities in logic and reasoning lag behind their linguistic capacity, and how a different model — the human brain — could point the way forward.

AI Psychology (some also use machine psychology)

An excellent retort to “that BOLD” paper making the rounds lately. A great example of needing to understand the assumptions of an analysis method.

Neural representations of visual memory in inferotemporal cortex reveal a generalizable framework for translating between spikes and field potentials Translating neurophysiological findings requires understanding the relationship between common measures of brain activity in animals (spiking activity) and humans (local field potentials, LFP). Prior ...

🚨 New preprint!

Why do some insights from spikes translate to field potentials while others don't? In this paper we compare visual memory representations in spikes and LFPs to propose a general framework that answers this question.

The Empiricism Gap in Computer Science So far, I have argued that there is a dissonance between, on the one hand, CS’s founding myths, curricula, and self-image, and, on the other hand, the modern production of knowledge in computer scienc...

If you've missed this piece about the different modes of empiricism in computer science versus the social sciences, I can highly recommend it. doomscrollingbabel.manoel.xyz/p/the-empiri...

Hopkins Cog Sci is hiring! We have two open faculty positions: one in vision, and one language. Please repost!

It responds to pictures, so no, it doesn't just operate downstream from the language network!

Many thanks to @evfedorenko.bsky.social and @nancykanwisher.bsky.social who brought me on to this project years ago, as well as to the whole author team: @carinakauf.bsky.social @ruimingao.bsky.social Selena She @hopekean.bsky.social T. Goldhaber, A. Nieto-Castañón, R. Varley 11/end

Overall, we find that semantic reasoning recruits its own neural machinery, distinct from the language network and other large-scale brain networks. This is cool! Lots of exciting follow-up work to do to establish precisely what these regions do. 10/

Finally, we examined vATL, a putative semantic hub. vATL voxels localized with the semantic>perceptual contrast respond to both sentence and pic semantics - AND to passive sentence reading. Thus, vATL is not sensitive to semantic task load, whereas our semantic regions are 9/

Single-subject brain plots show that these semantic regions are adjacent but largely separate from language, MD, and DMN regions. 8/

Semantic regions are also distinct from fronto-parietal multiple demand & default mode networks, other candidate systems that could be supporting semantic reasoning. 7/

These semantic regions are distinct from the language network - the latter shows a preference for linguistic stimuli, whereas semantic regions do not. 6/

We discover a set of brain regions that respond to semantic reasoning over both sentences and pics.The results are stable across our 3 experiments. These regions are located in left frontal cortex, left temporo-parietal cortex, and right cerebellum. 5/

Using group-constrained, subject-specific analysis (GcSS), we search for brain regions that respond to semantic>perceptual tasks (~matched for difficulty) for both sentences and pictures. To do so, we leverage data from 3 experiments with the same general design structure 4/

Critically, we posit that semantic reasoning can operate over various input types - e.g., sentences and pictures. 3/

Humans have the remarkable capacity to sift through vast amounts of stored world knowledge to extract information that is immediately relevant to their goals. We call this process ~semantic reasoning~ and set out to discover its neural basis. 2/

Semantic reasoning takes place largely outside the language network The brain's language network is often implicated in the representation and manipulation of abstract semantic knowledge. However, this view is inconsistent with a large body of evidence suggesting that...

Still the best course if you want to actually understand Bayesian stats.
