I recommend this article about AI reasoning, where the author lets us in on his struggles w/ AI cognitive dissonance. Plus some priceless quotes from @rao2z.bsky.social. (My recommendation has *nothing* to do with the fact that I'm quoted in it too 😇) www.quantamagazine.org/is-ai-reason...
Is AI Reasoning Right for the Wrong Reasons? | Quanta MagazineThe idea that artificial intelligence can “reason” is more intuitive than ever. But intuitions can be wrong, and the science is far from settled.www.quantamagazine.org

OSFosf.ioAre brain rhythms a steady hum or a brief buzz? Both. Alpha and beta activity are relatively sustained, helping maintain ongoing brain state, supporting its role in top-down control.

Universal rhythmic architecture uncovers two modes of neural dynamics - Nature CommunicationsBrain oscillations are traditionally regarded as sustained rhythms. Here, the authors show that there are both high and low-rhythmicity bands, characterised by brief bursts, which can signal responses...www.nature.com
Now out in an issue! Children find it easier to represent uncertainty about *what* an object is than *where* an object is, with interesting implications for both early possibility reasoning and object representations ~~ Check it out 👉 direct.mit.edu/opmi/article...
Children’s Representations of Possibility: Uncertainty About “What” Is Easier Than Uncertainty About “Where”Abstract. Young children struggle in situations involving mere possibility, such as when a target object could be in one of two possible locations. This difficulty is often interpreted as a general li...direct.mit.eduEsra Nur Turan-KüçükNew paper in Open Mind! 2-to-4-year-olds find it easier to reason about an object's possible identity than its possible location, and we argue this asymmetry traces back to the architecture of early object representations. 🧵
