My current research focuses on how the neurotransmitter dopamine influences attention and vigour. Rewards and penalties can motivate us to move faster and to be more accurate. I use eye tracking, reaction times, and distraction to measure reward processing. I am investigating how reward processing is affected by dopaminergic drugs, Parkinson's disease, and focal damage to the frontal lobe of the brain.
I am also studing how we sequentially search for information with our eyes, and how we retain information in visuospatial working memory.
