Group Dynamics/Persuasion

altruism

the likelihood of engaging in helping behavior

social facilitation

people perform better on a task when they are in the presence of others

social inhibition

people perform worse when they are in the presence of others

social loafing

the tendency to put less effort in a group effort than we would if we were working alone

diffusion of responsibility

people won’t take responsibility to help when they’re in a big group because they think that someone else will take action

deindividuation

tendency for people to behave in groups that they normally would not because no one would know about their actions

groupthink

tendency for highly cohesive groups to not think critically in order to be in unanimous agreement

group polarization

tendency for a group to adopt more extreme versions of their initial opinions because more people lean towards that idea

3 major factors that influence a situation

source, audience, message

foot-in-the-door

making a small initial request increases the likelihood of someone agreeing to a larger, subsequent request

door-in-the-face

initially making a large, unreasonable request to manipulate the person into agreeing to a smaller more reasonable request

central route to persuasion

being persuaded by information that is relevant to the argument/content

peripheral route to persuasion

being persuaded by information that is not relevant to the argument/content
