Prof. Castelli’s research interests lie in the areas of cognitive development and psychology and law. Specifically, she is interested in understanding the development of psychological processes underlying children’s memory accuracy. Her work focuses on the memorial and metamemorial processes involved in the formation and rejection of false memories, and aims to clarify the conditions through which existing memories are more (or less) likely to become distorted. Results from this line of investigation also help highlight the conditions under which children’s accuracy as witnesses can be compromised, or maintained.
