What develops when the id interacts with reality, coping with external demands?

The ego develops when the id interacts with reality, as it is responsible for managing the demands of the id while also considering the constraints of the external world. The id is driven by primal instincts and desires, seeking immediate gratification without regard for reality. The ego, on the other hand, serves as a mediator that helps navigate these desires in a socially acceptable manner. It employs various defense mechanisms and strategies to cope with external pressures and the demands of reality, ensuring that individuals can function effectively within their environment. This balancing act is essential for mental health and well-being, as it allows for the adaptation to real-world situations without succumbing solely to impulsive urges or external authority.
