Harlene Hayne has had a significant international impact in the field of developmental psychobiology. Her research findings on the development of memory have influenced the direction of research in other laboratories around the world. Her work has examined infantile amnesia and the way in which preverbal memory in infants translates into language. She has also furthered our understanding of deferred imitation in infancy, in age-related changes in memory, and in the way children are able to provide accurate eyewitness reports. In addition to her personal research achievements, Professor Hayne has been an effective research leader and ambassador for science.
