Biography and Research Interests

I completed my Ph.D. in Cognitive/Experimental Psychology at Stony Brook University in 2010. Since then, I have worked as a postdoctoral fellow in the Davis School of Gerontology at the University of Southern California. Here, I have received multidisciplinary training in how aging affects cognition, physiological change, and mental health.

In general, my research focuses on how social context influences memory across the adult lifespan. In answering this broad question, I have two main lines of research.

In my first main line of research, I examine how socio-cultural stereotypes about aging influence older adults? memory. Previous research has shown that negative stereotypes can adversely affect memory in older adults via stereotype threat. In my own research I have shown that this is due to changes in motivational orientation. When older adults encounter stereotype threat it induces a risk-averse, prevention motivational focus. Interestingly, because of this, my research shows that stereotype threat can not only impair older adults? memory, it can also enhance it. Stereotype threat can improve older adult?s memory when losses (rather than gains) are emphasized. It can also reduce older adults? memory errors. Some of these results have been covered in media outlets, such as Newsday, The Daily Mail, Headlines and Global News, and The Observer (from the Association of Psychological Science).

In my second main line of research I examine how collaboration modulates memory in both younger and older adults. My research to date suggests that 1) collaboration is associated with a decrease in the quantity of information that both younger and older adults learn and recall; 2) despite these decrements, collaborative recall also serves benefits, such as creating collective memories within groups; 3) collaborative recall may also lead to emotional benefits, particularly for older adults.

When stereotype threat can improve older adults' memory performance
Barber and Mather's in-press Psychological Science paper shows that stereotype threat can actually improve older adults' memories if the task is framed as avoiding losses.
