Imagine an apple 🍎. Is your mental image more like a picture or more like a thought? In a new preprint led by Morgan McCarty—our lab's wonderful RA—we develop a new approach to this old cognitive science question and find that LLMs excel at tasks thought to be solvable only via visual imagery. 🧵
Artificial Phantasia: Evidence for Propositional Reasoning-Based Mental Imagery in Large Language Models
This study offers a novel approach for benchmarking complex cognitive behavior in artificial systems. Almost universally, Large Language Models (LLMs) perform best on tasks which may be included in th...

Last month, I launched my lab at Ohio State. Our lab website is now live, and we're recruiting graduate students this cycle! If you're interested in the cognitive (neuro)science of learning & memory, please reach out!

I am recruiting graduate students for Fall 2026 through both the cognitive and developmental areas at Ohio State. If you are interested in spatial cognition, visual perception, and/or mental representation -- please reach out! I'd love to hear from you.

Isn't the Filled Duration Illusion usually about filling spaces with other discrete entities (analogous to the visual Oppel-Kundt illusion)? If so, I think those effects are substantively different, personally!

Great to have another paper with @chazfirestone.bsky.social @ianbphillips.bsky.social and the brilliant Hanbei Zhou out! In this paper we demonstrate that stimuli within events are perceived further apart in time — an event-based analog of “object-based warping”. psycnet.apa.org/record/2026-...

I’ll send over the latest draft that we had!

We’ve found the same when we’ve examined adherence to Weber’s law with different sorts of visual stimuli. Sam Clarke and I wrote up a paper recently that’s partly about this, but we haven’t known what to do with it.

The human visual system has specialized modular processing for multiple distinct categories of causal events.

Maybe! If we're thinking about such low-level explanations, then we'd have to apply the same skepticism to cases like number adaptation -- at which point we'd have to admit we cannot be certain about those cases, either.

I.e., per widely accepted standards, this is bona fide visual adaptation.
samiyousif.bsky.social
I agree it is tempting to think of low-level explanations! As we should for number, causality adaptation, etc.

But what low-level explanation could explain the cross-stimulus effects? We take that as a pretty strong answer to such concerns.

I’m not sure how they do so well so fast — but they do!
samiyousif.bsky.social
There's so much I want to say about why this paper is really exciting, but this is not ideally explained in a short thread. If you're interested in this sort of thing, I highly recommend checking out the paper for yourself!

Visual adaptation is viewed as a test of whether a feature is represented by the visual system.

In a new paper, Sam Clarke and I push the limits of this test. We show spatially selective, putatively "visual" adaptation to a clearly non-visual dimension: Value!

Can we “see” value? Spatiotopic “visual” adaptation to an imperceptible dimension
In much recent philosophy of mind and cognitive science, repulsive adaptation effects are considered a litmus test — a crucial marker, that distinguis…

On the left is a rabbit. On the right is an elephant. But guess what: They’re the *same image*, rotated 90°!

In @currentbiology.bsky.social, @chazfirestone.bsky.social & I show how these images—known as “visual anagrams”—can help solve a longstanding problem in cognitive science. bit.ly/45BVnCZ

I'm recruiting a lab manager for my soon-to-be-launched lab at Ohio State! If you know of any recent grads who may be interested both in helping to build the lab and in developing skills in the cognitive neuroscience of memory, please share!

There’s something funny about saying that someone caused something to happen when they didn’t act intentionally — as if that phrasing assigns unintended agency to them. Why is that?

In this new paper below, we take a linguistic approach to answering this question. Lots of interesting data here!

Suppose Tom loses control of his body, and his bodily motions then cause an accident. Would it be right to say “Tom caused the accident?”

A new paper explores the role that language plays in these links between agency and causation!

The first student-led paper from my lab -- from (first-year!!) undergraduate student @gabrielwaterhouse.bsky.social

This is my favorite kind of project: A neat, visible illusion, with compelling data from multiple paradigms, plus some interesting theoretical implications. Check it out!

I have noticed that many cool people are starting labs at Ohio State right now. I've decided to follow their lead.

Soon, my lab will be moving to Ohio State as well.

Incredibly excited and grateful to share that I’ll be starting a lab at The Ohio State University this(!) fall! My lab will study human learning and memory, with related interests in sleep, stress, and time perception. More info soon, but do get in touch if you’re interested in joining!

New preprint! How do we integrate new information into prior knowledge? We find that existing knowledge enables rapid new learning but that interleaved replay during sleep promotes integration of new and old information. Modeling suggests a sleep context suppression mechanism.
