I am a PhD candidate at the University of Toronto studying how memories are formed on a sub-second level. My research utilizes psychophysics and intra-cranial EEG to probe how LFP and neuronal activity relates to sub-second fluctuations in human memory.

Which factors are more vs. less important in predicting memory?
We systematically investigated the contributions of image memorability, valence, arousal, attention, and test delay.
Image memorability was the strongest predictor of memory.
Proud of this work led by @hartwakeland.bsky.social!
It has been such a pleasure to work on this paper! Beyond its intellectual breadth, what gives me great delight about this work is how the collaboration arose, thanks to @samversc.bsky.social. We read each other's papers, chatted about them on social media, and that eventually evolved into a paper!☺️

Our eyes don't linger because recognition is hard; they linger to remember. Let me take you on a quick tour. 🧵

"AI’s sycophantic tendency to always complete an assigned task can result in code that runs but is wrong, many researchers say. Vibed code might, for example, make up missing data to help an algorithm run, or even smooth a graph to make it look as expected." www.nature.com/articles/d41...

Our newest finding: tiny microsaccades are biased toward the location that is about to be attentionally suppressed.
This suggests that attention briefly precedes suppression: before the system can suppress a location, it first appears to select it.
By combining magnetoencephalography and eye tracking, this study sheds light on why people fixate on some parts of natural scenes longer than others. Rather than visual complexity, fixation durations ...

Statistical learning guide attention by shaping anticipatory oculomotor behavior. Here, the authors show that microsaccades are biased to expected distractor locations before stimulus onset and predic...
Zolnik et al. propose that the long-overlooked neocortical layer 6b (L6b) supports
a key circuit for attention and related cognitive functions. L6b integrates neuromodulatory

🎉New paper out today in Nature Reviews Psychology🎉 with @mjdahl.bsky.social, @mariamaly.bsky.social, and @thiasmittner.bsky.social.
We've been working on a unified framework for attentional states and the dynamics of transitions between them.

Long-term memory reorganization of navigational episodes

In this Article, Iggena et al. show that memories of real-world navigational episodes do not simply fade but are continuously reshaped over decades through shifting contributions of episode-related sp...
