Accepted to Linguistic Inquiry! I argue on syntactic grounds “some of the apples” is really “some apples of the apples” with NP-ellipsis. This explains which quantifiers and which modifiers (adjectives, prepositional phrases, relative clauses) can’t appear. Preprint: ling.auf.net/lingbuzz/009...

Are there any processes in cog psychology well characterized by a folded normal distribution?

Excited to share our new paper in Cerebral Cortex (w/ Ellen Lau)! In this MEG study on visual working memory (VWM), we showed that uni- and multi-variate signals complementarily track different aspects of VWM representations across different regions. academic.oup.com/cercor/artic...

🧠🧵 New paper accepted at @jocn.bsky.social! Led by @amyqixx.bsky.social We found that memory traces carry an "echo" of how they were last accessed: the way you retrieve a concept leaves a measurable signature in the brain the next time you recognize it. doi.org/10.1162/JOCN... 1/9

Memory Traces Reflect How They Were Last Accessed
Abstract. Episodic memories are known to change with each act of retrieval. We hypothesize that accessing semantic knowledge in different ways during episodic retrieval—from unique perceptual features...

Does anyone know if there are good published numbers on (American) English verb biases for alternating ditransitives? I.e. “give” is DO 8/10 times vs “toss” is PO 9/10 times. Either experimental norms or corpus derived

New paper in #ScienceAdvances! 10 ECoG patients performed 3 language production tasks: word, word list, and sentence production. We found surprising dissociations between how active cortical sites were and whether they encoded linguistic information: 🧵 [1/9] doi.org/10.1126/scia... @science.org

Hybrid spatial organization and evidence for magnitude-independent neural coding of linguistic information during sentence production
Brain recordings during speech reveal complex linguistic information throughout cortex, independent of neural activity levels.

A privilege & a pleasure to co-lead the 6th run of our “Genetics & Neurobiology of Language” course at the beautiful @cshlbanbury.bsky.social campus. Huge thanks to inspirational speakers, our fab TAs, talented early career researchers who joined as participants, & all who helped make it so special.

Excited to share a preprint of work done in collaboration with @emilynguist.bsky.social ! osf.io/preprints/ps... TLDR: some effect sizes are larger in lab than on web-based platforms. So when evaluating quantitative predictions, considering the testing platform can be important! 1/n

Quantifiers could be associated with different algorithms/hyperintensions from person to person, even if they all agree on truth conditions. Are they, in fact, variant in that way? We find evidence for “no! Everyone represents them the same!” Preprint here: ssrn.com/abstract=719...

Individual differences reveal underlying similarities in meaning: quantifier-dependent choices in verification procedure are consistent across individuals
Previous literature has investigated how quantificational sentences like 'Most of the dots are blue' are understood, using visual tasks which force pa

Excited to share our (w/ @smancha.bsky.social ) latest work, where we offered some EEG evidence suggesting that morphology and syntax might not be that different in language comprehension, capitalizing on some interesting properties of Mandarin Chinese. onlinelibrary.wiley.com/doi/10.1111/...

I should get paid to translate back and forth between classic symbolicist cog sci and Bayesian cog sci. “Agents infer latent causes with evidence from the sensory stream” = people guess what’s going on using abstract representations

This is likely predictable since it’s kinda my niche now, but I find it genuinely shocking that psycholinguists mostly gave up on studying sentence recall and recognition circa 1990 when there were and still are 10000 open questions

We wrote a thing -- showing you don't need LLMs to model language production dynamics like the tendency for speakers to reduce predictable words. All you have to do is better model how speech rate varies depending on where a word is and how long the utterance is. arxiv.org/abs/2512.23659

With some trepidation, I'm putting this out into the world: gershmanlab.com/textbook.html It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class. My hope is that this will be a living document, continuously improved as I get feedback.

Almost done grading for the course I (designed! and) taught this semester on connections between verbal working memory, sentence memory, and sentence production. I always thought it was just a cheesy thing to say, but you really do learn more from the students than you teach them
