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.

Proud to have contributed!

Children are often cast as passive vessels into which we pour culture. But children create cultures of their own—vibrant ones with special properties.

My paper with @stellalourenco.bsky.social ‬is now out in Science Advances!

We found that children have robust object recognition abilities that surpass many ANNs. Models only outperformed kids when their training far exceeded what a child could experience in their lifetime

Check out my interview in the CNS newsletter about my graduate research on free recall in children 😊
"Sometimes when it seems like young children don’t remember something you ask them about, it may be more of an issue of cognitive search and verbal fluency than memory per se." Read a new Q&A with @susanbenear.bsky.social about the development of free recall:
