Intrinsic rewards guide visual resource allocation via reinforcement learning
Nature Human Behaviour, Published online: 01 October 2026; doi:10.1038/s41562-026-02573-7Tangible rewards are known to sharpen visual processing of associated objects. Tomić et al. show that an internal sense of confidence—acting as an intrinsic reward—similarly biases attention, revealing how the brain prioritizes limited resources.

Description

Computational models in psychology are typically judged by a single standard: empirical fit. Unfortunately, fit is insufficient, even misleading as a sole criterion, as the same result can arise from fundamentally different situations: theoretically faithful models, mathematically flexible ones, miscalibrated operationalizations, or implementations that compute something other than intended. Distinguishing between these is vital. Our evaluative metatheoretical account recognises that models stand in three distinct relations: a) toward the theory whose causal commitments it purports to capture, b) toward the specification and implementation it purports to compute, and c) toward the phenomenon it purports to explain. Each relation can succeed or fail independently, governed by criteria local to that stage. Importantly, relations are ordered such that theoretical content is transmitted or lost, and losses at earlier transitions are irrecoverable downstream. What a model's empirical success implicates about its theoretical commitments, therefore, depends on whether transitions are secured. Some success or failure profiles support explanatory claims; others only prediction; others establish theoretical coherence without empirical contact. Our account diagnoses what a given model shows, replacing the implicit assumption that empirical success transfers automatically to theoretical understanding with an explicit conditional rendition of what models can and cannot establish.

What you see right now is not a livestream, but is delayed & edited by your brain 🧠. The brain uses a short time buffer to rewrite what you thought you saw using info that comes in later (postdiction). We study how (7T fMRI, retinotopy). Read our preprint: www.biorxiv.org/content/10.6... 👀 (1/N)

I am devastated by the death of Jason Arday - there is so much to say, but it is clear that so much of the hate and scrutiny he experienced, aswell as his tragic death, occurred because he was black. Society has to acknowledge the racialised nature of this, and the University its own failings.

Cuttlefish, squid, and octopuses have excellent memories, use tools, and are adept problem-solvers; they have a concept of time and are capable of delayed gratification. Some scientists think they are conscious (and possibly in a different way than us). www.nature.com/articles/d41...

Do octopus brains work like humans’ — or is there another way to be smart?
Just like vertebrates, cephalopods — such as octopuses and squid — have elaborate brains. Neuroscientists are flocking to them for insights into how intelligence evolved.
