🏰 New preprint! 🏰 (w/ the excellent @neuronomist.bsky.social & Prof. Jason Mattingley) For my PhD I've been using EEG, psychophysics and modelling to explore how the brain uses uncertainty to balance sensory information against expectations about what's out there. 🧵1/n

Fantastic presentation from @tvcottier.bsky.social kicking off our first meeting for 2026. His recent work suggests super-recognisers prioritise identity cues in faces over other dimensions, & that expressive cues interfere with them - suggesting these processes are not independent

Slide from Tim Cottier's presentation which says 'Super recognisers are more sensitive to expression' with plots showing the results

I really like this paper. I fear that people think the authors are claiming that the brain isn’t predictive though, which this study cannot (and does not) address. As the title says, the data purely show that evoked responses are not necessarily prediction errors, which makes sense!

Cognitive psych is often traced back to the 1950s. Psychology is often traced to Wundt's lab in 1879. Textbooks speak of "proto-psychologists" like Fechner & Helmholtz in the 1800s... Westerners all. Have you heard about Ibn al-Haytham, whose work predated them by 100s of years? 1/4
