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:

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.

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....

New paper out at Journal of Memory and Language! We knew that individual differences in working memory predict source memory, but did it predict simple item recognition memory (that relied on less attention resources than source memory)? Our answer is: YES! (with @edvogel.bsky.social ) 1/5
