Geoffrey White is an experimental psychologist with research interests in memory and discrimination processes. His published research examines the environmental conditions governing the ability of humans and animals to retrieve memories of past events, and includes studies of the effects of drugs on memory performance in animals. His theoretical models emphasize the quantitative measurement of behaviour. His model for memory involving decisions based on the individual’s history of pay-offs for successful performance won an award for the best integrative published paper from the American Psychological Association. Geoffrey White has also won distinguished research awards from the New Zealand Psychological Society of which he has been President. At present he is Deputy Vice-Chancellor (Research) at the University of Otago.
