Final answer:
The psychological structure that interprets the world and compares one's actual self to one's ideal self is known as Self-concept. It encompasses our beliefs, abilities, and personal characteristics, influencing all areas of our life.
Step-by-step explanation:
The psychological structure through which people interpret their world and make a comparison between their actual self and ideal self is known as C) Self-concept. Self-concept is a broad term that refers to the overall idea of who a person is, their self-identity, and how they perceive their abilities and attributes. This subjective perception comprises various beliefs one holds about oneself, including one's abilities, personal characteristics, and the comparison between the perceived actual self (who one believes oneself to be at present) and the ideal self (who one wishes to become or believes one should be).
This self-concept influences how we see ourselves and our roles in society. It is closely related to self-esteem, which is the level of confidence in our own abilities, and can affect a multitude of aspects in our lives, from our performance at work or school to interpersonal relationships. Congruence, a term often used in psychological discussions, describes a state of being where thoughts about our real and ideal selves are very similar, indicating a harmonic self-concept.
