I am interested in people's perception of environmental statistics and how they affect judgments and decisions. One line of research examines bias in memory for how long things have taken in the past and how that relates to predictions of when tasks will be finished. Specifically, when and how prediction of duration is likely to be incorrect. A second line of research examines people's perceptions of their own abilities. Previous research indicates that people often overestimate their ability on a number of different tasks, with a majority believing themselves to be above average. I am interested in whether or not people are truly biased in their self-perceptions.
Dr. Roy joined Dr. Karendra Devroop (assistant professor of music) and students from the departments of psychology and music established an instrumental music program at two disadvantaged schools in South Africa using donated instruments. I will be returning to South Africa later this year to examine impact of the intervention.
