Situation Variations Activity Variations
Manipulation Variations Fixed Attitude Variations
Perhaps the easiest way to get a feel for one's theme is to take each quad by itself, and experience the four Variations all at once to get a sense of the relationships between them.
In the Morality/Self-Interest quad, for example, the other two Variations are Approach and Attitude. It is the nature of these Variations that the other pair measures the good or bad nature of one pair. In this case, if we select either Morality or Self-Interest as the focus, we measure the contrast between them in terms of Attitude and Approach. If we explore Attitude and Approach, they would be measured by Morality and Self-Interest.
