YAY, so excited to read this today!!! 🧠💫

Understanding adolescent anxiety through a neurodevelopmental lens: A comparative review of rodents and humans Adolescence is a dynamic time period, marked by significant neural and behavioral maturation. However, much remains unknown about how this maturation …

📣New review 📣 Hot off the presses! This paper from a recent special issue in @fluxsociety.bsky.social was a collaborative effort between myself and co-lead author @rebeccahennessy.bsky.social with the support of our PIs Heather Brenhouse and Juliet Davidow. www.sciencedirect.com/science/arti...

So thrilled to see this out -- reading IMMEDIATELY!!! Congrats to you and the team 🎉

So grateful for this collab with rockstar @caitlyncody.bsky.social and our mentors! Excited to share our translational take on the neurodevelopment of anxiety in adolescence (and can’t believe my first publication is live!)

My website is official 🙌 Excited to share that I am interested in reviewing applications for Harvard’s Clinical Science PhD program this fall as I look for the first student to join my lab! I appreciate it if you can share with your network :)

Seeking WV scientists! My dad (a non-scientist who works with scientists) is leading a FABBS delegation to discuss NIH funding with Senator Capito in August and needs to build the delegation. Please reach out and I’ll put you in touch with him! CC @standupforscience.bsky.social

Welp. I'm a postdoc whose NIH funding source has just been cancelled in a mass grant termination targeting Harvard. We've been using these funds to study how puberty affects the brain and adolescent mental health.

Dream team!!!!! 💫

New paper with @catehartley.bsky.social

How does the reward structure of the environment influence the specificity with which children, adolescents, and adults learn and remember information?

See preprint 🧵 and paper for our efforts to answer to this!

Stoked to be at my 1st in-person SANS this week! I'll be presenting "Emotion 😀😨 and Reward 💰 Information Influence Choice in Age-Varying Ways" at poster P2-B-31 tomorrow afternoon. Looking forward to conversation and feedback! #SANS2025

Had so much fun collaborating on this! 💫

Thanks so much! ☺️

🧵 9/X

Our take-away: when some of the information about the benefits & costs of cognitive effort needs to be learned, exertion becomes more economical into adulthood. During childhood & adolescence, aims may not translate into actions.

🧵 8/X

For completeness, in our secondary experiment, both the reward & difficulty cues were instructed. We believe that the removal of learning demands made the task easier. Accordingly, we no longer found strategic cognitive effort allocation in older participants.

🧵 7/X

We also found that participants of all ages reported trying harder when there were greater rewards at stake — even though we only observed reward-boosted performance in adults.

➡️ This hints at a gap between goals & realized behavior in younger participants.

🧵 6/X

➡️ This suggests that adults, but not children & adolescents, economically exerted their cognitive effort.

🧵 5/X

In the primary experiment, the reward cue was instructed, but the difficulty cue had to be learned through experience. We found that reward-based titration of task accuracy emerged with age & difficulty-based titration of task accuracy somewhat emerged with age.

🧵 4/X

A participant who invests their cognitive effort efficiently would try hard to get trials correct in high reward & low difficulty blocks, but not in low reward & high difficulty blocks.

🧵 3/X

We tested 300 participants (ages 10–20 years) across 2 experiments using a child-friendly task-switching paradigm🌙👾🪐. The task blocks varied in rewards & difficulty, & these blocks were proactively cued.

🧵 2/X

Are children & adolescents similarly economical? TLDR: they may say that they are, but their behavior tells a different story.

🧵 1/X

Adults learn to exert their cognitive effort when it's economical to do so — i.e., when the benefits (like rewards offered for performing a task well 💰) outweigh the costs (like the difficulty of the task 💪).

🧠💡 NEW PAPER ALERT 💡🧠

Together w/ Isabelle Jacques, @katieinsel.bsky.social, @arossotto.bsky.social, & Leah Somerville, the 1st project from my PhD is now out in JEP:G!

How do children, adolescents, & adults decide when to think hard? Our study examines learning the value of cognitive effort.

Current Directions in Psychological Science article entitled More Than Just a Phase: Adolescence as a Window Into How the Brain Generates Behavior

Excited to share this brief review where @katieinsel.bsky.social & I discuss studying adolescence to understand how brains work! We highlight avenues for future collaborative work at the intersection of cognitive, computational, & developmental neuroscience 🧠
journals.sagepub.com/doi/10.1177/...

Very excited that this fun collaborative piece with @aliocohen.bsky.social is now in press!

We highlight how insights from adolescent brain development can shape and enhance computational models of learning.

Abstracts are due FRIDAY! Submit submit submit! 🧠💫

Go Hayley + team!!! 🎉
