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

Less is more: Probabilistic reduction is best explained by small-scale predictability measures The primary research questions of this paper center on defining the amount of context that is necessary and/or appropriate when investigating the relationship between language model probabilities and ...

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

I thought CCG did, or was at least incredibly close to doing so at the level of categorial combination (concatenation). Ignoring whatever the semantic correlate representations are ofc

Super-Thick Chocolate Chip Cookies Recipe, à la Levain Bakery Inspired by Levain Bakery, these giant chocolate chip cookies are a dessert of epic proportions.

Not sure if it’s the recipe you’re following, but the serious eats levain “style” chocolate chip cookie recipe is the closest I’ve made. Gets the horizontal, vertical, and craggly aspect of the Levain cookie right with a relatively simple recipe! www.seriouseats.com/super-thick-...

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

Nothing makes me miss the southwest more than lack of access to puerco en chile verde/puerco asado (red chile). Hope they came out well!

If anyone is around for SNL down the block from me, I have a sandbox poster on Sunday! I present some very preliminary data examining cued sentence recall with MEG. If you care about sentence recall, MEG sentence production, or combining psycholing with memory tasks, stop by poster E19!

I’ll be presenting a poster at HSP 2025 in about a week. It’s on memory for pronominal clitic placement in Spanish, come stop by and say hi if you can!

It’s so funny when someone does incredibly fancy bayesian cognitive modeling and then their data analysis is just like a frequentist ANOVA lol

I thought of a really annoying generativist thing to say when someone asks you about doing cross-linguistic studies: well, if you take I-language seriously then nearly every study is “cross-linguistic”

Taking a syntactic formalisms class and I gotta say while MCFGs are cool they also produce some of the ugliest trees out there
