Talk by Dr. Nika Adamian (Liverpool John Moores University): "Attentional selection in dynamic vision: a steady-state visual evoked potential approach"

Keeping track of multiple moving objects in a cluttered, dynamic environment is a fundamental challenge for visual attention. A key question is what determines the limits of this ability, and whether those limits are attentional in nature. To address this, I will draw on the steady-state visual evoked potential (SSVEP) technique -- an EEG-based frequency-tagging method that allows the strength of attentional enhancement to be measured continuously. I will demonstrate that SSVEPs are a versatile tool for studying covert and overt spatial attention as well as feature-based attention, and I will then present data from a series of experiments applying this approach to multiple object tracking. These experiments examine how various task demands affect attentional allocation to tracked targets and reveal that bottom-up display characteristics and top-down attentional control contribute independently to tracking performance, with implications for how we understand attentional limits in dynamic visual environments.
