Abstract Emotions vary in intensity. But what is it that vanes? There are many parameters that can be considered parameters of emotional intensity, and it is unclear how these parameters are related. The main question of this study is: Is the subjective intensity of emotion one dimensional, and, if not, what are its dimensions? We sampled 222 instances of emotions, and for each instance subjects completed a questionnaire. The subjects also drew a diagram of the course of their emotion over time. A factor analysis of the intensity questions and the diagram variables yielded six factors: (1) duration of the emotion and delay of its onset and peak; (2) perceived bodily changes and strength of felt passivity; (3) recollection and re-experience of the emotion; (4) strength and drasticness of action tendency, and drasticness of actual behaviour; (5) belief changes and influence upon long-term behaviour; and (6) overall felt intensity. Most specific dimensions correlated moderately with overall felt intensity. Special attention is given to the relation between intensity and the duration of emotion.
