Welcome to the Positive Emotions and Psychophysiology Laboratory

We study people’s emotions, particularly their positive emotions.

We are interested in how positive emotions affect people’s thinking patterns, social behavior, health, and physiological reactions. Our ultimate goal is to understand how positive emotions might accumulate and compound to transform people’s lives for the better.

Our techniques include analyzing reactivity in people’s autonomic nervous systems and facial muscles. We also assess the breath of attention and cognition using various computerized reaction time tests. We are also expert in asking people to report on their subjective experiences of emotions and emotion-related experiences using both on-line and retrospective techniques.

This site is intended to appeal to scientists, students, as well as the interested public. If you would like information beyond what this website provides, please contact Professor Barbara Fredrickson.
