Social Influence

When a person or group uses any type of social power to change the attitudes or behavior of others in a particular direction, they have used social influence. For example, a persuasive argument might be even more effective if your teacher (an authority figure with social power) is an expert on a topic as opposed to just having some knowledge about the topic. If the teacher is able to change your attitude in the direction of the argument, they have used a type of social influence.
