Professor Timothy Rickard's research interests include human memory and performance, skill learning and transfer, and numerical cognition. He investigates these topics with cognitive laboratory studies, neuroimaging studies, patient studies, and quantitative modeling techniques. Current projects explore: 1) the changes in cognitive processing and representation that occur with practice, 2) memory impairment in patients with damage to the medial temporal lobe, 3) the role of attention in memory retrieval, and 4) the cognitive and neurological structures involved in numerical cognition.
