Assistant Professor of Psychology
"My primary research interest is on cognitive aging, especially on how language and memory processes change over time. I am particularly interested in understanding how cognitive processes change with healthy aging, so we can better understand how these processes generally work and we can work on dispelling misconceptions about growing older. I specialize in an everyday memory failure known as the tip of the tongue (TOT) experience (when you know you know a word but when you try to say it, it’s just a bit out of reach and feels like it’s on the tip of your tongue) and other real-world retrieval problems. I also investigate influences on everyday financial decision making, especially in the context of real-world problems like elder financial exploitation and mass marketing scams."
