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

Attention reshapes the representational geometry of a perceptual feature space
Department of Psychological and Brain Sciences, Boston University Our perception of the world is transformed by attention, both in terms of the efficiency of information processing and the appearance ...

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

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...
