 One of the most enduring and important ideas of Sigmund Freud was that the human mind can be divided into three levels of consciousness, the unconscious, pre-conscious and conscious minds. My name is Robin Wallast, I'm a doctor in psychology and in this video we will explore three personality structures which are the Eid, Ego and Super Ego. The Eid operates in our unconscious mind which means that it is not accessible to our consciousness. The Eid is often pictured as a little devil whispering on your shoulder. He is selfish, instinctual, impulsive and refers to an unconscious psychic energy that strives to satisfy basic needs such as sex, eating and aggression. Specifically, the Eid is based on the pleasure principle which demands immediate gratification by gaining pleasure and avoiding pain. Think about a newborn child who is crying because he seeks pleasure through food and attention with no regard to the consequences. He demands immediate gratification regardless of the burden caused to his parents. Next, the second personality structure is the Super Ego which is mostly unconscious and often pictured as the little angel smiling on your shoulder. He is like an internal judge who is based on the moral principle. He tells you what is right and wrong, what is socially acceptable to do, think and feel according to real-world rules, moral and norms. Finally, the third personality structure is the Ego which is basically our conscious self. The Ego is who we think we are, it has the ability to make decisions. The Ego operates on the reality principle. It is like an executive mediator who tries to satisfy both the needs from the Eid and Super Ego in a realistic way. Let me give you a concrete example. Imagine that you have to study for an exam or you have homework to do. The Eid is based on the pleasure principle and immediate gratification so when you will start studying you will have thought like this is boring or am I doing this and the Eid will put pressure on you to do something pleasurable like watching a TV series, going on social media, anything that will give you immediate gratification. Then, the Super Ego is based on the moral principle and will act like a judge by giving you thoughts like doing my homework is the right thing to do. I should do it for my career and the Super Ego will pressure you by rewarding or punishing you. For instance, you will feel proud like a good student if you study or ashamed like a terrible student if you quit your task before finishing it. Between the Eid and the Super Ego you have the Ego which is based on the reality principle. The Ego will find a compromise by analyzing both sides. That's right, this homework is a bit boring and I want to do something more pleasurable but if I don't make it, I might fail my exam or my class and so the Ego will find a decision in a realistic way. This is how the three personality structures work. Thank you for watching.
