Explain what is meant by the imaginary audience, the personal fable, and the illusion of invulnerability. Give an example of each

What will be an ideal response?

A good answer will be similar to the following:
- The imaginary audience is the feeling of many adolescents that they are, in effect, an actor whose performance is watched constantly by their peers. For example, a teenager who got a haircut she didn't like might insist on staying home from school, because she thinks all the kids at school will stare at her funny haircut and make fun of her.
- The personal fable refers to teenagers' tendency to believe that their experiences and feelings are unique, that no one has ever felt or thought as they do. For example, a teenager whose parents didn't allow him to attend a concert with his friends might think his parents are being so unreasonable because they could never understand what it feels like to have to miss out on something all your friends are doing.
- The illusion of invulnerability refers to the common tendency of teenagers to believe that misfortune only happens to others. This might explain the tendency of teenagers to engage in risky behaviors, such as driving too fast or having unprotected sex, because they don't think the possible negative consequences of these acts will happen to them.
