Saturday, I'll have another poster on work with Philip Resnik & @colinphillips.bsky.social exploring how we can enrich a toy cognitive model of reaction times in a speeded cloze task with data from language models.

I'll be presenting some work comparing how humans and LMs make predictions at #HSP2026 this week, please reach out if you'd like to meet!

Tomorrow, I'll have a poster on work with @byungdoh.bsky.social comparing cloze & LM surprisals as predictors of reading time hsp2026.org/abstracts/su...

Figure 1 Illustration of why AI systems cannot realistically scale to human cognition within the foreseeable future: (b) Human cognitive capacities (such as reasoning, communication, problem solving, learning, concept formation, planning etc.) can handle unbounded situations across many domains, ranging from simple to complex. (a) Engineers create AI systems using machine learning from human data. (d) In an attempt to approximate human cognition a lot of data is consumed. (c) Making AI systems that approximate human cognition is intractable (van Rooij, Guest, et al., 2024), i.e., the required resources (e.g. time, data) grows prohibitively fast as input domains get more complex, leading to diminishing returns. (a) Any existing AI system is created in limited time (hours, months or years, not millennia or eons). Therefore, existing AI systems cannot realistically have the domain-general cognitive capacities that humans have. [Made with elements from freepik.com.]

DEFINITELY not talking about predictive coding the next time i go back to the bay area

The sycophantic tone of ChatGPT always sounded familiar, and then I recognized where I'd heard it before: author response letters to reviewer comments.

"You're exactly right, that's a great point!"

"Thank you so much for this insight!"

Also how it always agrees even when it contradicts itself.

When it comes to text prediction, where does one LM outperform another? If you've ever worked on LM evals, you know this question is a lot more complex than it seems. In our new #acl2025 paper, we developed a method to find fine-grained differences between LMs:

🧵1/9

Table 1 Typology of traps, how they can be avoided, and what goes wrong if not avoided. Note that all traps in a sense constitute category errors (Ryle & Tanney, 2009) and the success-to-truth inference (Guest & Martin, 2023) is an important driver in most, if not all, of the traps.

NEW paper! 💭🖥️

Capturing Online SRC/ORC Effort with Memory Measures from a Minimalist Parser Aniello De Santo. Proceedings of the Workshop on Cognitive Modeling and Computational Linguistics. 2025.

A bit late but since I really like this paper, a bit of self-advertising! I am presenting at CMCL today work showing that metrics measuring how a Minimalist Grammar parser modulates memory usage can help us model Self-paced reading data for SRC/ORC contrasts: aclanthology.org/2025.cmcl-1.5/

New preprint on controlled generation from LMs!

I'll be presenting at NENLP tomorrow 12:50-2:00pm

Longer thread coming soon :)

thanks a lot Kanishka! happy i made a little contribution & that the probabilities are corrected :)

another day another minicons update (potentially a significant one for psycholinguists?)

"Word" scoring is now a thing! You just have to supply your own splitting function!

pip install -U minicons for merriment

I’ll also be presenting a talk based on this work Friday afternoon at HSP. Very excited to share it with a psycholinguistics-focused audience!

I’ll be at #HSP2025! I’m presenting a poster in session 4 on how semantic factors might affect timing data from a speeded cloze task (w @virmalised.us, Philip Resnik, and @colinphillips.bsky.social)

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!

Generalizations across filler-gap dependencies in neural language models Katherine Howitt, Sathvik Nair, Allison Dods, Robert Melvin Hopkins. Proceedings of the 28th Conference on Computational Natural Language Learning. 2024.

RNN LMs can learn many syntactic relations but fail to capture a shared generalization across constructions. Augmenting the training data with more examples helps, but not how we'd expect!

Language models can identify who did what to whom, but they may not be using human-like mechanisms, based on materials from different psycholinguistic studies finding systematic patterns in human processing.

5-gram of the day: "language models from computational linguistics"

I’m so sorry but cool to see another psycholinguist who came from the CS route! I interned on a database team and hated it. The other reviews were good. It’s just a very random process

GRFP reviews sigh

Today I learned that I may not have a successful psycholinguistics career because I got a B in databases.
