Very happy to announce that our paper “Sensory Horizons and the Functions of Conscious Vision” is now out as a target article in BBS!! @smfleming.bsky.social and I present a new theory of the evolution and functions of visual consciousness. Article here: doi.org/10.1017/S014.... A (long) thread 🧵

A new paper, forthcoming in PPR: Visual Icons This paper took me more than 5 years to write. It argues that the visual system constructs imagistic representations ("visual icons") and sketches a theory of how visual icons, and iconic representations generally, are compositionally structured.

Functionalists should insist that what matters for consciousness is whether a system fulfills a function, not whether it is fit for a function. If you put my heart on a table it's fit for pumping blood but it doesn't fulfill its function. Same for an isolated global workspace.

A neural basis for distinguishing imagination from reality

Dijkstra et al. show that our brain distinguishes imagination from reality by monitoring how strongly the fusiform gyrus is activated. When imagined and real images produce similar activity, people ca...

for students in mainland China who are interested in neuroscience & philosophy, what platform do they use to get updates? if a Chinese prof is to have a blog w/ regular posts, which platform would be the best for reaching the students? little red book? something else?

Enjoying this talk about how to inflict maximum tickle. For anyone curious: (1) Touch velocity non-linearly modulates ticklishness, (2) force monotonically increases ticklishness until the touch is perceived as painful, (3) the smallest contact size & (4) longer duration induced more tickle #ESCAN

1/ Periodic reminder: decodable ≠ causally used. Or, as we put it: Represented Is Not Computed. New paper w/ the excellent Ishita Darade (not on BSky; www.linkedin.com/in/ishita-da...), an undergrad student: arxiv.org/abs/2605.22488 #representation #NeuroAI #neuroscience #interpretability

Represented Is Not Computed: A Causal Test of Candidate Algorithmic Intermediates in a Transformer

Structured prompts require integrating components according to task-relevant relations. How a network implements this integration is often hard to judge in language or vision, where those relations ar...

Once upon a time, representational momentum seemed to be about motion. Then Alon Hafri + @jorge-morales.bsky.social + others extended it to other continuous visual properties. Can we go even further? At 2:45pm in the Banyan Breezeway, @talboger.bsky.social reports repmo for written phrases! #VSS2026

Trial structure for Tal's "phrasal momentum" taskPhrasal momentum The world looks different from one moment to the next, and various mental processes anticipate such changes. A foundational example of this anticipation is representational momentum (RM), wherein the mind ‘plays forward’ visual events. For example, falling objects are recalled as closer to the ground, and rotating rectangles are recalled as more rotated. Though early studies hypothesized that RM primarily concerns the anticipation of motion, recent work demonstrates that it arises for other continuous properties, such as the brightness of a stimulus or even how melted an ice cube appears. Here, we extend representational momentum even further than these sophisticated phenomena, to discrete (rather than continuous) properties, as well as to more conceptual (rather than purely visual) properties of the world. Participants watched animations of common phrases being typed; the animations were interrupted partway through (e.g., “The quick brown fox jum”), and participants used a slider to recall the phrase’s state at the moment it disappeared. 5 experiments revealed ‘phrasal momentum’: The mind plays forward the phrases we see, in ways that distort visual memory. This distortion was greater for real phrases than for (a) strings of “X”s (Experiment 1), (b) length-equated strings of random letters (Experiment 2), and (c) scrambled versions of the words composing the phrases (e.g., “heT kicqu rbnow oxf”; Experiment 3). We also observed a stronger distortion for normal, in-order phrases than for word-shuffled versions of those same phrases (e.g. “The quick brown fox…” vs. “Fox quick the brown…”; Experiment 4). Finally, Experiment 5 found that phrasal momentum follows a conceptual ‘gradient’; in a single experiment combining all the aforementioned conditions, normal phrases produced the strongest RM effects, followed by shuffled phrases, scrambled letters, random letters, and Xs. Thus, representational momentum arises even for discrete and non-visual stimuli.

It's #VSS2026! SO excited about the projects we've brought with us this year, and of course #phiVis to close things out. Come say hi, and don't forget to grab your lab 'merch' 👀 perception.jhu.edu/vss/

Introducing meta-🔼! (meta-delta) Really excited about this one. We provide a principled, performance-corrected measure of metacognitive bias, placing it on an equal methodological footing with meta-d, and showing robust test-retest reliability to boot. Check out Kevin's thread for more details! 🧠🧪

In a new preprint w/ @tianqizhan.bsky.social & @smfleming.bsky.social, we developed a new measure of metacognitive bias (over/under confidence in individual decisions)! doi.org/10.31234/osf...
