Thesis title: Perceptual cycles and transient attention captured by motion

Supervisors: Irina HARRIS , Alexander HOLCOMBE

Thesis abstract:

Studies using paradigms that enable the examination of the time course of attentional selection have found two components-transient and sustained attention. A robust finding is that transient attention deploys quickly when summoned by a stationary cue, rapidly rising to peak performance after which it declines. This pattern is consistent with perceptual cycles—the intrinsic rhythm of visual attention that results from a regular cycle of neural oscillations. However, our recent preliminary research suggests that motion produces a different and more sustained pattern of performance after the initial peak. My thesis will investigate how this is reflected in the perceptual cycles and whether the patterns found differ depending on the type of motion.
