Final answer:
Freud's model of the mind describes the difference between the immature and mature mind. The immature mind is driven by the unconscious id and seeks immediate gratification, while the mature mind is influenced by the ego and superego, striving for rationality and balancing instincts with social rules.
Step-by-step explanation:
Freud's model of the mind suggested that the immature mind is driven by the unconscious id, which contains our most primitive drives or urges, such as hunger, thirst, and sex. The immature mind operates on the pleasure principle, seeking immediate gratification. On the other hand, the mature mind is influenced by the development of the ego and superego, which help control the id and balance the demands of instincts and social rules. The mature mind operates on the reality principle, striving for rationality and realistic ways to satisfy desires.
