The term that describes our understanding and evaluation of who we are is self-concept. Self-concept encompasses the beliefs, feelings, and perceptions that we hold about ourselves and is fundamental to our identity. It includes various dimensions, such as our self-esteem (how we feel about ourselves), self-identity (how we see ourselves in the context of societal roles), and self-knowledge (what we know about our traits and characteristics).
Self-image relates more specifically to how we perceive our physical appearance or outward qualities, while self-confidence pertains to our belief in our abilities and judgments. Self-awareness, on the other hand, involves recognizing our own emotions, thoughts, and behaviors, but it does not fully capture the broader understanding and evaluation that characters self-concept. Thus, self-concept is the most comprehensive term in this context, reflecting our overall understanding and evaluation of who we are at a fundamental level.
