I’m super excited to finally put my recent work with @behrenstimb.bsky.social on bioRxiv, where we develop a new mechanistic theory of how PFC structures adaptive behaviour using attractor dynamics in space and time!

How is prefrontal neural activity refined as we age?

Out today in @nathumbehav.nature.com‬! This study, from Elizabeth Johnson, uncovers how subtle changes in neural 'noise' impact our attention, memory, and cognition through development.

A brain-imaging study of people with amputated arms has upended a long-standing belief

go.nature.com/3Jp9NPG

The brain’s map of the body is surprisingly stable — even after a limb is lost

Study challenges the textbook idea that the brain region that processes body sensations reorganizes itself after limb amputation.

Is the hippocampus best understood in term of discrete subfields or functional gradients?

Functional gradients are recapitulated within each hippocampal subfield, supporting a role for both discrete & continuously changing computations.

Still, these results hint that internal strategies, shaped by the environment, may help explain SES gaps in learning. Understanding this better could help us design interventions that support exploration in all learners. 🚀 7/7

Lexi Decker @lexidecker.bsky.social · Jul 31

Critical caveats: our study is cross-sectional (so, no causality), and our lab task may not capture the many types of exploration important for learning, including in educational contexts, like asking a risky question in class or exploring a new topic.

Lexi Decker @lexidecker.bsky.social · Jul 31

Computational modeling revealed that higher loss aversion helped explain why lower-SES children explored less. When losses feel bigger, taking exploratory risks may become less appealing.

Lexi Decker @lexidecker.bsky.social · Jul 31

In a decision-making task, we found exactly this: lower-SES children took fewer exploratory risks and exploited more, and this shift was related to reduced learning and academic achievement. Exploration on the task also covaried with grades and academic skills.

Lexi Decker @lexidecker.bsky.social · Jul 31

We zoom in on a fundamental part of learning: the balance between exploring new options and exploiting known rewards. Theory predicts that in environments with fewer resources, children might play it safe, exploring less, exploiting more.

Lexi Decker @lexidecker.bsky.social · Jul 31

External barriers, like reduced enrichment or support, contribute to lower learning outcomes for children from lower-SES backgrounds. But what about internal decision-making strategies?
