Mood congruence

In psychiatry, mood congruence is the congruence between feeling, or the emotion that a person is experiencing, and affect, or the manner in which that emotion is "presenting", or being expressed.

Examples:
 * Congruent mood - smiling while feeling happy.
 * Non-congruent mood - smiling while feeling anxious.
 * Inappropriate affect - laughing while describing a loved one's funeral, for instance.
