How do we learn to achieve our goals? 🧠Computational Cognitive Neuroscience PhD student UC Berkeley 🌿

New paper! Setting goals is so useful in complex settings because it can reduce the environment's complexity to only the goal-relevant features. But for humans, reframing comes at a cost. Could this explain why we're so bad at abandoning goals that are no longer worthwhile? 🧵

📢 New preprint! How do humans learn from arbitrary, abstract goals? We show that, when goal spaces can be compressed, costly working-memory processes give way to internalized reward functions, enabling efficient goal-dependent reinforcement learning. @annecollins.bsky.social arxiv.org/abs/2509.06810

Reward function compression facilitates goal-dependent reinforcement learning

Reinforcement learning agents learn from rewards, but humans can uniquely assign value to novel, abstract outcomes in a goal-dependent manner. However, this flexibility is cognitively costly, making l...

Generative AI is a cultural transmission technology: it plays a growing role in generation, selection and transmission of ideas/opinions in human society 🧠🔄🌐 And yet we understand very little of this dynamics at this point 🤔❓ A step forward is our #ICLR2025 paper !👇

What's wrong with evaluating #LLMs after a single interaction? Come find out @iclr-conf.bsky.social and learn how cultural attraction theory can help us do better. Poster #288, 10 am.

Have you ever gotten lost in fantasies and thought to yourself, "What a waste of time"? Well, think again! In our new piece in Current Opinion in Behavioral Sciences, Moshe Bar and I explain one reason why spontaneous thoughts, even when seemingly useless, may be key to human intelligence.

Stop by @neuripsconf.bsky.social poster #3909 11 am - 2 pm today if you want to wish me a happy birthday, hear about goal selection in RL, or both! @pyoudeyer.bsky.social @annecollins.bsky.social

I'm excited to announce that this work has been accepted at @blog.neurips.cc.web.brid.gy 🧠🤖 We hope to spark conversations on goal selection in biological and artificial agents. Check it out at openreview.net/forum?id=Gbq... With Cédric Colas, Pierre-Yves Oudeyer, & Anne Collins
