Dimensional models of core affect: A quantitative comparison by means of structural equation modeling

The present article compares dimensional models of affect with each other. The article focuses on the pleasure-arousal model, the energetic and tense arousal model, and a three-dimensional model with separate pleasure-displea sure, awake-tiredness, and tension-relaxation dimensions. The results show that the three-dimensional model cannot be reduced to a tl;two-dimensional model. Problems of the two-dimensional models' reductionism are discussed. I We conclude that a three-dimensional description of affect is necessary. However, the three-dimensional model is not sufficient to account for all a spects of the structure of affect.
