Vicente Raja; but I want to be Luffy. Ramón y Cajal Research Fellow at the University of Murcia (Spain). Associate Faculty at the Rotman Institute of Philosophy (Canada).

Random question again: If perceptual experience is based on the optimisation of an internal model (or controlled hallucination), why the optimisation process can't solve myopia, for e.g.? Myopia is a relatively simple optical issue that an optimised internal model (w/ priors) could solve. Why not?

Why would you even both calling your approach ecological if you explicitly endorse indirect perception and representational solutions? Gibson should have trademarked the name. This is honestly getting out of hand

In a new @cp-neuron.bsky.social article, members of the Simons Collaboration on Ecological Neuroscience (SCENE) outline their plans to investigate how the brain links perception, cognition and action by encoding environmental affordances: https://bit.ly/49YfgaE

"If we ask ourselves candidly 'what has neuroscience taught us about cognition that we did not already know from behavior?' we realize that unfortunately the answer is 'not very much.'" (Niv, 2021) I'm curious about what's the general take in the field about this claim 🤔

Luis Favela and I just finished editing a special issue on dynamical cognitive science for topiCS. The great contributors of the issue talk a little bit about what happened in the last 30 years, where we are now, and where we are heading to. Here's the intro (open access): doi.org/10.1111/tops...

Dynamical Cognitive Science! Wherefore Art Thou?

How has dynamical systems theory—especially the dynamical hypothesis—influenced the cognitive sciences since the 1990s? This topic brings together informatics, linguistics, neuroscience, philosophy, ...

Ah... I'm so invested in what we could call "non-standard approaches to cognition" that I often forget that out there in the real world we still lay comfortably in the arms of Immanuel Kant/René Descartes/pick-your-own-Modern-poison... www.nature.com/articles/d41...

Does AI already have human-level intelligence? The evidence is clear

The vision of human-level machine intelligence laid out by Alan Turing in the 1950s is now a reality. Eyes unclouded by dread or hype will help us to prepare for what comes next.

As an ecological psychologist, when I read: "the PBDR approach is always grounded in the physics of light transport... [...]... because it allows the identification of perceptual invariants." It actually sounds like: "we use the optic array to find perceptual invariants." I like it!

Legit super excited about this work coming out. My amazing doctoral student @ben.graphics has been working on an idea to use physically based differentiable rendering (PBDR) to probe visual understanding. Here, we generate physically-grounded metamers for vision models. 1/4 arxiv.org/abs/2512.12307

A teaser figure showing the process of metamers rendered differentially (MRD). Target scene parameters are used to render a target scene. A new scene is initialized from some starting point, and renders are created from this scene. The loss between the initial and target scenes is measured. MRD allows the gradients wrt the loss to be propagated to the scene parameters (e.g. lighting, geometry or material) for gradient-based optimization.

"meaningful affordances" "bio-mechanical affordances" "mental affordances" "non-representational affordances" Please stop. Stop with the adjectives. It makes no sense. Thank you.

Is ecological neuroscience a feasible enterprise? After some theoretical work on ecological resonance, we've engaged on experimental research to test some of the hypotheses that follow from it. These are the first results of (hopefully) many more to come! It's open access 👇 doi.org/10.1111/psyp...

"Although neuroscience has developed powerful tools for measuring brain activity, its behavioral measures are far more primitive, as it lacks a coherent conceptual framework for analyzing and interpreting behavior." True! Happy to see this idea is growing. www.sciencedirect.com/science/arti...

Aligning brain and behavior

To understand how the brain generates behavior, both brain activity and behavior must be measured accurately. Although neuroscience has developed powe…

It never ceases to amaze me how angry some people in mainstream cognitive science get when one talks about non-representation/non-computation while they completely refuse to at least read something about it so they can have an actual reason to be angry that is not just "hey, normal science, bro".

David Lee just died. He formulated tau/time-to-contact, the most famous bit of ecological information. He is one of the main reasons why ecological psychology is still alive. We all are indebted to him. I met him once and ended up having dinner at his place. Very cool guy! RIP
