Ger’s research is focused on perceptual decision-making and attention, and how these functions interact in the human brain. This currently involves the measurement of behaviour, EEG, and eye-tracking in response to visual stimuli. The goal of this research is to discover how the brain initiates and facilitates the process of making perceptual decisions. Another research interest of Ger’s is the extent to which visuospatial attention is biased to the left or right hemifield and how this can be used as an indicator of Attention Deficit Hyperactivity Disorder and Alzheimer’s disease.
