A Logical Model for Narcissistic Personality Disorder

In this paper, the authors propose logic for the specification of some types of feelings, emotions and behaviours related to Narcissistic Personality Disorder disease. The targeted feelings here are Grandiosity, Truly/Wrongly Better Feeling, and Wrongly Right/Wrong Feeling, while the emotions are Envy and Admiration, and finally Exploitativeness is the unique behaviour studied. This research is multidisciplinary since it invokes both psychology and logic. Therefore, the authors had to draw the sources of this study in psychology to build a logical model that they used as a framework to represent some characteristics of the narcissistic personality. The logical model built allows expressing and recognizing the targeted feelings, emotions, and behaviours. They coupled it with an inference engine in order to use it as an aid in diagnosing whether a person is suffering from NPD, based on emotional, behavioural, and feeling information.
