Research Interests

Dr. Joshua Weller's (Health/Decision Making) research broadly focuses on how affective and cognitive processes contribute to decision-making and risk perceptions. Dr. Weller's lab is currently conducting research addressing four specific questions: (1) How do decision-making abilities change from childhood to older age? (2) In what ways may child maltreatment impact the development of these abilities? (3) How does stress impact decision making? and (4) To what degree do individual differences in personality correlate with decision-making processes and risk perceptions?
