Decision making particularly regarding life-issues does involve emotions. We could categorize emotion into two classes namely positive emotions and negative emotions for the practical purposes in the context of decision making. Most often final decision is our response to our emotions/feelings (positive or negative). If positive we affirm the decision if not we discard the decision.
It is in this context, APPRAISAL THEORY could help us in assessing the intensity of emotions - I assume.
