how does memory support perceptual decisions made under uncertainty? this question has scaffolded my entire PhD, and I'm so excited to share part of it in this ✨new preprint ✨ w/ @meganakpeters.bsky.social and @aaronbornstein.bsky.social! link: www.biorxiv.org/content/10.6...

Memory retrieval explains dynamic effects of expectations on perceptual decisions
Expectations—prior knowledge of environmental statistics—support adaptive behavior by reducing uncertainty during inference. However, the questions of where expectations come from and how that ought t...

New lab preprint! @khoudary.bsky.social presents a tour-de-force: a new model of how uncertain expectations should help resolve uncertain sensations, supported by re-analysis of four experiments in monkeys (behavior, ephys) and humans (behavior, fMRI, EEG, intracranial) @meganakpeters.bsky.social

Democrats do not only need to "go all in" on higher education. The party needs a genuine reset on its understanding of it. The last three Democratic administrations contributed to creating the crisis that higher ed is facing today.

The conclusion is NOT "we need to debias LLMs" Besides that it's impossible, it also detracts from the point, which is: We shouldn't use machines to offload of the very cognition that is constitutive of the work to be done & supercharge existing inequities and injustices in the process. 🧵

“Nobody is losing control of an emerging intelligence. They’re redirecting their own agency to the thing they are building.” It’s a myth, a self-affirming form of sense making: they take the action to build it, but insist on describing it as if they are passive witnesses to an inevitable force.
