The discipline of psychology and its sub-disciplines of social, cognitive, and industrial psychology undertake to identify taxonomies that help to identify, understand, and explain human behavior. In consideration of the traumatic effects of narcissistic parenting, this paper will discuss a single case analysis of patient A. In light of this patient’s upbringing, I will discuss two main personality theorists, Freud and Jung, to describe patient A’s self-reported personal identity, as he understands himself. I will describe the milestones that helped to formulate his beliefs, values and behaviors, familial and interpersonal relationships. The goal I will accomplish is to formulate a developmental assessment to support my theoretical perspectives of patient A.
