Broaden-and-Build Theory of Positive Emotions

The Broaden-and-Build Theory of Positive Emotions was developed from the Positive Psychology movement. It analyzed mental health in two levels: positive experiences (i.e., involving happiness) and positive traits (e.g., courage and wisdom).

According to this theory, positive emotions offer 3 benefits for the development of our mental health:

1. Positive emotions broaden people's mindsets. For example, the positive emotion of joy brings about an urge to play; and the positive emotion of interest brings about the urge to explore.
2. Positive emotions increase our physical, intellectual, social, and psychological resources.
3. Positive emotions fuel the growth of positive traits, like resilience.
