This document discusses a video presentation assignment in social psychology. It describes 5 concepts illustrated in 5 scenes of a story about a prefect abusing his power towards a student. The concepts are: 1) Schema - How the student develops a negative schema of prefects due to one prefect's behavior. 2) Ingroup bias - How the prefect favors other prefects over normal students. 3) Explicit attitude - How the prefect is aware of his different treatment of teachers vs students. 4) Optimistic bias - How the prefect thinks bad consequences won't happen to him. 5) Confirmation bias - How the teacher ignores negative information about the prefect due to already seeing him as a good student.
