Tracking covert attention over space and time using RIFT

Presenter: Kabir Arora

When navigating through the visual world, we constantly shift our attention from one point to the other. We often do this in a covert manner, without any clearly visible signature (such as moving our eyes). This makes these shifts difficult to study, and therefore we know relatively little about how they actually operate. How does our attention move from one point to another? Here, we use Rapid Invisible Frequency Tagging (RIFT) in an EEG experiment to track the allocation of spatial attention over time and space during covert attentional shifts, showing a suppression of attention at the location between the shifts around 150ms after it begins.
