Tim Murphy

Professor Tim Murphy holds a PhD from the University of Waterloo and is affiliated with the Department of Psychology at Brock University. His primary research focuses on understanding how sleep deprivation and sleepiness affect cognitive performance, electrophysiological markers (e.g., ERPs), and risk assessment behaviors. Key areas of exploration include EEG and ERP indices of brain function during sleep deprivation, habituation effects on attention, and risky decision-making in alert vs. sleep-deprived states. Future research directions aim to investigate combined effects of sleep deprivation and mild intoxication, alongside potential countermeasures like caffeine and napping.

His work integrates behavioral, EEG, and ERP methodologies to study topics such as sleep inertia, performance monitoring, and the neural correlates of error awareness. Notable studies examine how sleep loss impacts reward processing in gambling tasks and the reliability of medial frontal negativities during learning tasks.
