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.

The idea that personality and mood states help people make sense of their worlds. When a person whose default' mood mismatches their personality (e.g., an extraverted person who is by default more likely to experience positive mood, but instead experiences negative mood), this results in a delay in how quickly people make sense of their situation.
