Answer:
Normative social influence.
Step-by-step explanation:
- Normative social influence is when people conform or act a certain way because everyone else is doing it and fear the consequences of going against the group. Ex: One laughing at a joke they didn't find funny because everyone else is laughing. This is the best answer given the context of the Stanford Prison Experiment.
- Group polarization is when the viewpoints of a particular movement or group become more extreme than the original intended motives of the movement, with time. Ex: A group of people who hold moderate views about the Shrek movie tends to demonstrate heightened beliefs about the movie following group discussion.
- Obedience is compliance with an order, request, law, or submission to another's authority. Ex: A person is against certain content being allowed in film and on TV due to religious obedience.
- Informational social influence is when people follow the actions or advice of others due to a lack of information or confusion they may have. Ex: People follow the advice of experts during a crisis because of the oversaturation of opinions in the media.
- Social loafing is when people exert less effort due to more people being involved. Ex: As soon as my friend came to move the heavy boxes, I primarily move the lightest ones.
