New preprint with @SamJung @timbrady.bsky.social and @violastoermer.bsky.social: osf.io/preprints/ps.... Here we uncover what might be driving the “meaningfulness benefit” in visual working memory. Studies show that real objects are remembered better in VWM tasks than abstract stimuli. But why? 1/

excited to share this new preprint w/ Melissa and @racheldenison.bsky.social we measured the representational geometry of orientations using behavioral similarity judgements, and found that attention expanded representations around target orientations with a broader compression around distractors

recently posted a new preprint (the first of my postdoc 🎉) where we implemented normalization across space *and* time, allowing us to capture several neural and behavioral findings! I'll be presenting this work at VSS in a couple of months too for those attending www.biorxiv.org/content/10.1...

A dynamic spatiotemporal normalization model for continuous vision

Perception and neural activity are profoundly shaped by the spatial and temporal context of sensory input, which has been modeled by divisive normalization over space or time. However, theoretical wor...
