Our memories define us as individuals, they record our personal histories on an autobiographical timeline. Memory is also central to our intellectual lives, as almost every cognitive task requires retrieving information from memory. Thus, memory is among our most important cognitive faculties. But some individuals are better at searching memory than others. And we all tend to get worse at searching memory as we grow older. I want to understand the source of these age-related and individual differences. In studying these age-related and individual differences, I combine behavioral experiments, computational modeling, and multivariate analyses of neural representations.
