Final answer:
The concept of 'the self' in psychology is best aligned with Rogerian Theory, which concerns the self-concept and focuses on individual perceptions and growth within the self.
Step-by-step explanation:
The structure of the self is a concept that has been explored through various theoretical frameworks in the discipline of psychology. The offered options include Cognitive Development, Rogerian Theory, Social Environment, and Emotional Intelligence. While each of these can relate to the self, the closest fit for the 'STRUCTURE: THE SELF:_____________' would likely be Rogerian Theory. Carl Rogers' Humanistic approach to psychology, and specifically his Rogerian Theory, emphasizes the self-concept, which is key to one's personal identity and self-structure.
Rogerian Theory focuses on the individual's subjective view of the world and posits that the self-concept has three different components: the view of oneself (self-image), the value associated with that view (self-esteem), and the ideal self (what one wants to be). It is concerned with how individuals perceive and interpret their experiences and emotions to develop a robust and well-adjusted sense of self. Rogerian Theory aligns closely with seeking to understand the structure of the self.
