Final answer:
Khloe's behavior of judging herself based on comparisons to others exemplifies self-comparison, which ties into one's self-esteem as defined by social theories.
Step-by-step explanation:
Khloe often judges every aspect of herself based on how she thinks she compares to others. This is an example of self-comparison. The concept of self-comparison is closely related to Charles Herbert Cooley's theory of 'the looking-glass self,' where individuals shape their self-concepts based on how they believe others perceive them. Furthermore, social theories suggest that self-comparison can play a significant role in the development of one's self-esteem.
Self-esteem refers to the overall value one places on oneself as a person. High self-esteem is associated with a positive self-concept and vice versa. A person with high self-esteem generally feels confident in their own abilities and is thus less likely to persistently compare themselves to others, while someone regularly engaging in self-comparison might reflect lower self-esteem or certain insecurities.
