Children leverage predictive representations for flexible, value-guided choice
By harnessing a mental model of how the world works, learners can make flexible choices in changing environments. However, while children and adolesceβ¦

We show that children πΆ use predictive representations (e.g. SR) to guide their choices, providing an account of how they can make flexible choices in a changing world

They didn't need the scientific literature, nor faculty input, to do the right thing all along. They have always had more access to private data, which must tell the same story as the public data even more clearly. It's distressing to admit but the only thing that has changed is the political winds.

I am not sure how far this goes back in Earl's thinking. For my own part I legit expected Earl's early experiments to find grandmother cells for task set variables in pfc (maybe based on my own shallow reading of eg miller & cohen) and was surprised when he found mixed codes instead.

To be fair, Earl was probably fifteen years ahead of this becoming a commonplace idea in deep networks (which arguably happened only quite recently with the ideas about superposition in LLMs)
