Final answer:
An individual with a fully developed superego is characterized as morally conscious and guilt-prone, reflecting the internalized societal norms that guide their sense of morality.
Step-by-step explanation:
An individual with a properly developed superego is best described as morally conscious and guilt-prone. The superego plays a critical role in our personality, acting as our moral compass and it is responsible for our sense of right and wrong. It develops through social interactions and internalizing societal norms, leading us to feel pride when we meet these ideals and guilt when we do not.
The superego's emergence is a pivotal aspect of Sigmund Freud's psychoanalytic theory, emphasizing the internalized moral standards we acquire from our surroundings. An overly dominant superego can lead to excessive guilt and restrict socially acceptable pleasures, while a weak superego may permit psychopathic behaviors.
