1/ Our brains probably don’t store a new copy of “red” when we encounter something red. Yet we can reinstate distinct memories of red objects. How do we reuse what we already know when encoding memories? Excited to share new work led by @haoliu4391.bsky.social, with @marcelomattar.bsky.social 🧠🧵

1/10 🧠 Imagine seeing a cute dog before it runs away. A few seconds later, your friend tells you this was a Corgi. To remember this experience later, your brain has to link the dog (who is now out of sight) with the name you just heard.

Should your therapist look like you? As a Lebanese therapist, I've experienced the magic of validating another person through shared language & customs. And yet, similarity isn't always what helps us grow. My essay below explores benefits & limitations of "identity matching" in therapy!

Broke: all models are wrong but some are useful Woke: models are useful because they are wrong
I am recruiting graduate students for UCI's PhD in Cognitive Sciences - www.cogsci.uci.edu/graduate/pro... The lab's focus is on how relational structure and combinatorial reasoning is implemented in human brains and large language models--and if they are similar.
