Research interests
I am a first year PhD student in Clinical Neuropsychology, conducting research on the underlying neural mechanisms of cognitive control and reward learning in the laboratory of Dr. Clay Holroyd. Currently my research is focusing on how children with ADHD use rewards to modify their behaviour. To do this, we are using event-related brain potentials (ERPs) obtained while children navigate their way through a virtual maze in search of rewards. Based on the recent theory that the event-related negativity (ERN) is modulated by dopamine reward predication signals, we are looking at the amplitude of the ERN as a measure of how these reward prediction signals may be impaired in children with ADHD. Additionally I am interested in how individual differences in traits like risk-taking and empathy may affect the ERN.
