Final answer:
A script is a guide to expected behaviors in certain events, based on past experiences and social roles, and is influenced by cultural norms.
Step-by-step explanation:
A script guides our expectations of how an event will go, based on our previous experience. This concept, also known as event schema, refers to a person's knowledge about the sequence of events expected in a specific setting. Scripts are formed through our social roles and are fundamental in guiding behavior in various situations, like entering an elevator or visiting a restaurant. They can be influenced greatly by cultural differences, indicating that what is considered normal behavior in one culture can be perceived very differently in another.
