Classification of Emotions

[lpetrich]

 Emotion classification and  Contrasting and categorization of emotions list several schemes, along with problems of definition.

A simple one is the circumplex model or the valence-arousal model. It may be illustrated with this table:
[table="class: grid"]
[tr][td]Anger[/td][td]Active A+E+[/td][td]Happiness[/td][/tr]
[tr][td]Unpleasant V-N+[/td][td][/td][td]Pleasant V+N-[/td][/tr]
[tr][td]Sadness[/td][td]Inactive A-E-[/td][td]Relaxation[/td][/tr]
[/table]
A = arousal, V = valence.

It is closely related to these dimensions of personality:
E = extroversion, N = neuroticism,
two of the dimensions of the OCEAN five-factor model of personality.

There are some other schemes, though they are more complicated.
