Professor Hale conducted research that focused on developmental changes in speed of information processing across the life span and on the role of age-related and other individual differences on other aspects of cognition. Currently, she is beginning a two-year phased retirement during which she will be teaching and finishing up a few research projects.
In particular, Hale developed a line of research that examined the cascade of developmental changes in processing speed on the development of working memory and higher level reasoning abilities. Other research projects included examination of how sensory and cognitive abilities affect lip reading and listening comprehension in both children and adults.
