Preparing overt eye movements and directing covert attention are neurally coupled. Yet, this coupling breaks down at the single-cell level. What about populations of neurons?
We show: EEG decoding dissociates preparatory overt from covert attention at the population level:

My first TEDx talk just came out. It's always fun to talk about your own research area to the general audience, and its even more fun when you are lucky enough to be supported by such a platform. Happy to hear your thoughts :-)

Our commentary @stigchel.bsky.social on Ruth Rosenholtz' Visual Attention in Crisis paper is now available:

We argue that effort must be considered when aiming to quantify capacity limits or a task's complexity.

Celebration time 🥳 @liangyouzhang.bsky.social publishes the 1st empirical paper of his PhD!
We show that numerosity adaptation (a seemingly high-level stim property) suppresses neural responses in early visual cortex; these adaptation FX increase as we progress thru the visual processing hierarchy.
We show that numerosity adaptation (a seemingly high-level stim property) suppresses neural responses in early visual cortex; these adaptation FX increase as we progress thru the visual processing hierarchy.
Numerosity adaptation suppresses monotonic neural responses to numerosity displays in the early visual cortex, with more suppression for higher numerosity adaptors. Therefore, numerosity adaptation effects begin in early sensory stages of processing.

Highlighting a supplementary analysis we added: Prior work showed that cross-decoding asymmetries can sometimes be driven by SNR differences between conditions instead of 'true' neurocognitive effects. We simulated EEG data and showed that SNR is unlikely to account for our cross-decoding results.

In all experiments, we found a consistent pattern: pupil size tracked attentional breadth and WM load independently. This converges with recent EEG decoding work demonstrating a dissociation between spatial attention and working memory gating.

We analyzed pupil size - which reflects both spatial attention and WM load - data from three experiments wherein attentional breadth and working memory load were manipulated independently. For example, using dot cloud stimuli the spatial extent of stimuli were orthogonal to the number of clouds.

Spatial attention and working memory are popularly thought to be tightly coupled. Yet, distinct neural activity tracks attentional breadth and WM load.
In a new paper @jocn.bsky.social, we show that pupil size independently tracks breadth and load.

1/ Why are we so easily distracted? 🧠 In our new EEG preprint w/ Henry Jones, @monicarosenb.bsky.social and @edvogel.bsky.social we show that distractibility is associated w/ reduced neural connectivity — and can be predicted from EEG with ~80% accuracy using machine learning.

Surely you know about eye dominance. You probably don’t know it’s not a unitary phenomenon: in this paper I show that sensory eye dominance varies over the visual field. In the Discussion I propose an explanation for why this variation might exist. Curious? Read it here: doi.org/10.1167/jov....
