The rich get richer in visual processing: latest study with @ivntmc.bsky.social shows that we allocate resources preferentially to stimuli that we feel confident in estimating, which makes us better at estimating them...even if the initial confidence was misplaced. doi.org/10.1038/s415...

Weird, how reality is more alarming than ostensibly "alarmist" climate scientists were not too long ago. And this is still just at the beginning of a warming trend that will continue for several decades at least (unless human beings suddenly become much smarter than ever before. I have my doubts.)

Online Now: Bayesian efficient coding as a theory of perception: progress, controversies, and prospects

Bayesian efficient coding as a theory of perception: progress, controversies, and prospects
Bayesian efficient coding unifies two foundational theories of sensory processing: efficient coding and Bayesian inference. Central to this account is the idea that natural environmental statistics shape both how sensory information is encoded and how it is perceptually interpreted. By unifying these principles, the framework accounts for counterintuitive perceptual biases and establishes lawful relationships between environmental statistics, bias, and discrimination thresholds. In this article, we review behavioural and neural evidence for this theory in perception and cognition, as well as how short- and long-term adaptation to the environment may be expressed within the framework. We further review theoretical developments that extend the original framework, focusing on how response biases can be decomposed into encoding- and decoding-related components. A decade after its introduction, Bayesian efficient coding continues to evolve as a powerful theory, with recent extensions addressing early limitations and opening new directions for investigating perception and cognition.
