My main research interests are in memory and memory disorders, particularly in those kinds of memory problems that occur as a result of normal or pathological aging or as a consequence of brain damage or injury. My students and I are particularly interested in understanding the relation between memory and executive functions and how they interact during different cognitive tasks. We are also developing rehabilitation techniques to help people with memory impairments improve their memory performance by taking advantage of preserved processes to compensate for those that have been damaged or lost. Current projects include studies of source memory, prospective memory, and self-referential processing. We are also studying the effects of social interaction and mindfulness on memory in older adults, and the effects of age-related hearing loss and hearing aids on cognitive function. We have a long-standing and continuing longitudinal study of changes in memory and executive function as people age and of the individual difference variables that might affect these changes. I teach courses in memory and memory disorders and in cognitive aging.
