Jody is a psychology major and her friend Sarah is an exercise science major. Both are currently taking Intro Psych they both forgot to take Exam 2. The professor tells Jody that she may have a week extension on her test for full credit because she is in the "psychology club;" meanwhile, the professor tells Sarah that she may take the exam for 80% credit just like the rest of the students who forgot to take the exam. This is an example of: 1)stereotyping
2)prejudice
3)discrimination
4)group polarization
