Executive control, action monitoring, selective attention
My lab investigates the neural underpinnings of, and interplay between, action monitoring and selective attention. A current focus is on how the commission of errors impacts the processing of sensory stimuli and associated behavioral consequences. My research takes advantage of electroencephalography, event-related potentials (ERPs) and brain stimulation techniques such as transcranial alternating current stimulation (tACS) to examine the neural correlates of these cognitive processes.
