That's a fascinating argument, thanks for bringing it to my attention, Jim!

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...

📢 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

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 !👇

When LLMs Play the Telephone Game: Cumulative Changes and Attractors in Iterated Cultural Transmissions As large language models (LLMs) start interacting with each other and generating an increasing amount of text online, it becomes crucial to better understand how information is transformed as it passe...

This paper concludes a long, exciting journey, which started several years ago when I first met Moshe. It's been a fantastic ride! Thank you Moshe, Bar Ilan University, and Onward Israel for enabling it ♥️ and the editors Deniz Vatansever and Jessica Andrews-Hanna for inviting us to contribute!

Spontaneous thought as play: the value of fictional goals in the default mode network Given its prevalence in our wakeful mental activity, spontaneous thought (ST) has been attributed several roles in cognition, most of which engage the…

In light of its similar merits, ST deserves at least the same care, protection, and appreciation we devote to children’s play. Get access to the full article here: www.sciencedirect.com/science/arti... @elsevierconnect.bsky.social

Similarly, we propose that ST provides a cognitive platform for simulating outcomes and ideas that extend beyond immediate constraints. As long as a fictional goal provides enough structure, even unrealistic STs can contribute to our cognitive flexibility.

In play, children engage in "fictional" goals. @junyi.bsky.social, @joshtenenbaum.bsky.social and Laura Schulz argued that these seemingly trivial activities enhance children's capacity to plan, innovate, and simulate complex scenarios.

To answer this question, we draw an analogy between ST and children's play.

The usefulness of ST is often connected to the proactive simulation of future scenarios related to our goals. But what about ST that engages in frivolous or highly unlikely situations?

Spontaneous thought (ST, the relatively unrestricted thought process that accompanies much of our waking life) benefits cognition in several ways, from memory consolidation to mood enhancement. Check out work by Judith Mildner and @dianatamir.bsky.social for an awesome recent perspective on this.

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.

How do we decide which goals to pursue? Here, we introduce the notion of *latent learning progress* to explain human goal selection and inspire advances in the development of autotelic machines. osf.io/preprints/ps...

The notion that goals are central to human cognition is intuitive, yet learning and decision-making researchers have often overlooked the topic. In this Trends in Cognitive Sciences review, @annecollins.bsky.social and I propose it’s time to start studying goals in their own right 🧠 t.co/He6PIpQdt9
