Research Focus

Professor Vazire's research examines people's self-knowledge of their own personality and behavior. She uses a combination of methods, including self-reports, informant reports, experience sampling and naturalistic behavior observation using the Electronically Activated Recorder (EAR). Her goal is to measure how people differ from one another not just at the trait level but also in their patterns of fluctuations across different roles and situations. She examines how much insight people have about their own and close others' traits and patterns. She is also interested in how personality and social relationships (e.g., friendship) influence well-being. Finally, she is interested in research methods, and factors that affect the vailidty and replicability of psychological research.
