If you're interested in the cognitive neuroscience of memory feel free to email me!

I do experimental psychology, brain imaging (fMRI and MEG) and a bit of modelling. Lab is doing stuff on forgetting, aging, schemas, and event boundaries, but we're not limited to that.

It's that time of year when many start thinking about applying for PhDs. If you're applying for a UK PhD position, here is a blog post I wrote a while back that might be helpful

Should I start telling students to get degrees in AI instead of cognitive neuroscience? Asking for a field.

Another new-ish paper: Events in the stream of behavior

Maverick Smith, @jzacks.bsky.social, and I discuss how the brain (esp. the Default Mode Network) represents event models, leveraging different information domains and scales of information processing.

Next up, from @atabk.bsky.social and @wouterkool.bsky.social: Free recall is shaped by inference and scaffolded by event structure. In sum, Ata stuck hidden (and shifting) rules into a word list learning task, creating "events" that influenced the structure of recall.

Check out a new preprint from Adi, postdoc working with me and Jeff Zacks. I’m *extremely* excited to finally, officially get this out into the world 🙂

1/ 🚨 Preprint alert!
How does the brain make sense of continuous experience?
We find that continuous experiences can be compressed using a subset of key moments that dominate comprehension and recall.

I just got NOAs on an NSF grant and an R01 in the same week, and I cannot begin to put into words the bizarre combination of relief, exhaustion, elation, and survivor’s guilt I am currently feeling.

What a fun and surreal day. Huge congrats to @atabk.bsky.social for defending his dissertation. I couldn’t be more proud ❤️

I’m just sitting here looking at the list of grant applications I had planned to work on this summer, and struggling to avoid the conclusion that it will be a huge waste of time.

Thanks for the kind words 🙂 I do want to interject some levity and clarify that, despite what she’d want you to believe, she was a deeply weird and unserious creature. And although the bar for dachshunds is pretty low in this regard, she was *so* smart. It was occasionally a problem.

You might have seen this pup in some of my papers and presentations. This is Maddie, and she was my best friend in the whole world. We had 16 wonderful years together. This past week has been incredibly hard, but it’s helped me refocus on what really matters amidst all the chaos in the world.

Zach Reagh @zreagh.bsky.social · Apr 28

Check out our new study by @atabk.bsky.social! He tweaked a word list memory task to have hidden rules at encoding, which shifted and created “event boundaries.” People recalled pre-boundary words more, and post-boundary words less. Other fun bits in the paper include a reinforcement learning model!

Communications Psychology @commspsychol.nature.com · Apr 28

This study examines how events structured recall, which was impaired for items after event boundaries. A reinforcement learning model showed that decision certainty predicts recall success.

Zach Reagh @zreagh.bsky.social · Mar 30

This is SUCH a cool study. Know that one effect event boundaries have on temporal order memory? The impairment they cause? Turns out that effect depends on the “events” being arbitrary. Things look very different when you test order memory for meaningfully-associated events.

Yining Ding @liliand.bsky.social · Mar 30

Excited to share our new preprint! Using a narrative reading paradigm, we showed that temporal order memory reconstruction can depend on multiple sources of information - factors like knowledge about typical event order and hierarchical event structure can both play important roles! 📖🧠

Hey friends! Come say hi to folks from my lab and from @jzacks.bsky.social lab at #CNS2025. We have a bunch of in-progress stuff this time, including a “sketchpad series” by @raynatang.bsky.social. Also, Veronica and June (with @alexbarnett.bsky.social) were undergrads when they did their projects 🙂
