Trait-Consistent Mood State

The idea that both personality traits and mood states convey information about the self in the world. When traits and states mismatch, epistemic uncertainty results, causing a delay when a person is asked to encode new events with reference to his or her feelings or motivations. As such, a trait-consistent mood state is when one’s trait mood (i.e. dispositional mood) and state mood (momentary mood) match.
