Love seeing photos of my lab presenting at conferences. ESPECIALLY love photos of lab members who are co-presenting. Yay teamwork! 😊 Check out the poster by @CraigPoskanzer & @RaheemaJavid. Preprint below and modeling work in progress 👀 osf.io/preprints/psyarxiv/us…

Excited to share this project! Across 3 experiments, we find consistent evidence that encoding and prediction are coupled-- not competitive. See our preprint or come to my poster at SFN (PSTR305.12) to see some follow-up modeling work!

Does encoding the present compete with predicting the future? In 3 behavioral studies, we find that encoding and prediction are coupled, not competitive! Proud of @CraigPoskanzer & @hannahtstoll for leading this work w/ Raheema Javid & Edoardo Spolaore! osf.io/preprints/psyarxiv/us…

Many people enjoy trivia, but some people are way better at it than the rest of us. What is different about their memory? Our research (w/ @monica_too_ & @_laurenwilkins_) characterizing the memories of trivia experts is now out and featured in @sciam! scientificamerican.com/artic…

A former Jeopardy! winner led a new study that probes how linked memory systems may give trivia buffs an edge in their game

What makes some people better at trivia than others? in one of the most insane multi-year "research is mesearch" journeys ever, we (me + @_laurenwilkins_ + @mariam_s_aly ) ran a study to answer this very question! psyarxiv.com/fm82b/ check it out!! 1/ 🧵

How do we balance paying attention to the external world vs our internal thoughts? The basal forebrain & dorsal attention network dynamically interact with the hippocampus to balance external and internal attention. Super proud of @CraigPoskanzer! 😊 jneurosci.org/content/early/…

Attention waxes and wanes. How do these fluctuations influence memory? Worse attentional states lead to more errors in the moment — but memory is just as temporally structured later on! Excited to share work led by @manasijkumar w/ @chinmayi_balusu! authors.elsevier.com/c/1gilY…
Figure showing a) the procedure for identifying "in the zone" and "out of the zone" attentional states; b) "out of the zone" attentional states are associated with more task errors than "in the zone" states; and c) "in the zone" attentional states are associated with better subsequent recall than "out of the zone" states.

Figure showing that "in the zone" and "out of the zone" attentional states lead to memories that are similarly structured in time.

Excited to have our paper (mdpi.com/2076-3425/13/2/296) in @BrainSci_MDPI. Recent imaging studies suggest face identity and expression information are encoded in common brain regions. With @katieoneuro @rebecca_saxe & @steanze, we offer a computational hypothesis for this phenomenon.

Thrilled to share my work with @steanze. Connectivity between brain regions can transform information nonlinearly - in this paper we propose and validate a novel method to 1) identify nonlinear interactions and 2) distinguish between different kinds of nonlinear interactions.

4. Finally, we demonstrated that there were small, but significant nonlinearities in the FFA’s interactions with other regions.

5. Understanding nonlinearities in neural interactions is an important topic in computational neuroscience. We hope that our method can be a useful tool in this effort!
