Social influence Psychology manifests through different mechanisms that shape human behavior in group settings. The two primary types of social influence are Informational Social Influence (ISI) and Normative Social Influence (NSI), each leading to distinct behavioral changes.
Definition: Informational Social Influence (ISI) occurs when individuals conform due to cognitive reasons, believing others know better than them, especially in ambiguous situations. This typically results in permanent behavioral change through internalization.
The process of conformity under ISI involves accepting others' behavior as correct and incorporating it into one's belief system. Research by Lucas et al. demonstrated that students showed greater conformity when faced with difficult mathematical problems, supporting the ISI theory. This indicates that uncertainty drives people to look to others for guidance.
Psychology A Level mind maps often highlight how NSI differs from ISI, as it involves conforming due to emotional reasons like fear of rejection or desire to be liked. This typically results in temporary change where individuals may publicly agree while privately maintaining different beliefs.

The Asch conformity experiments provide crucial insights into Social influence Psychology. The study involved participants making visual judgments about line lengths while surrounded by confederates giving incorrect answers.
Example: In the original setup, one genuine participant sat among 7-8 confederates who deliberately gave wrong answers. The conformity rate reached 37% when participants faced unanimous incorrect responses from the group.
Key variations in the study revealed important factors affecting conformity:

The Stanford Prison Experiment, conducted by Zimbardo, demonstrates how Social influence Psychology operates in institutional settings. The study transformed ordinary college students into guards and prisoners, revealing the powerful impact of social roles on behavior.
Highlight: The experiment had to be terminated after just 6 days, instead of the planned 2 weeks, due to the escalating psychological distress among participants and increasing guard brutality.
The study involved 24 male volunteers randomly assigned to roles as either guards or prisoners in a simulated prison environment. Guards were given uniforms, clubs, and reflective sunglasses, while prisoners wore uniforms with identification numbers. The rapid deterioration of participants' psychological well-being demonstrated how situational forces can override individual personalities.

The concept of obedience in Social influence Psychology involves complex interactions between personality traits and situational factors. The Authoritarian Personality theory, proposed by Adorno, suggests that certain individuals are more predisposed to obey authority figures due to their upbringing and personality structure.
Vocabulary: The Agentic State refers to a condition where individuals act as agents for authority figures, feeling no personal responsibility for their actions while following orders.
Research supports this through the F Scale questionnaire, which measures authoritarian tendencies. Studies show that individuals who scored higher on the F Scale were more likely to demonstrate obedient behavior in Milgram's experiments. However, this explanation has limitations as it doesn't fully account for why some people resist authority despite having similar personality traits.

Social influence is a core topic in AQA A Level Psychology, focusing on how individuals' behaviors and beliefs are affected by others. This page introduces key concepts and types of social influence.
Definition: Social influence refers to the ways in which individuals change their behavior to fit in with a group or society.
The main types of social influence discussed are:
Highlight: Understanding the differences between these types of social influence is crucial for answering AQA A Level Psychology social influence questions.
The page also introduces two key explanations for conformity:
Vocabulary:
- NSI: Normative Social Influence
- ISI: Informational Social Influence
These concepts form the foundation for understanding more complex ideas in social influence, which are essential for creating a comprehensive Social influence mind map for revision purposes.
