Understanding Social Influence in Psychology: Core Concepts and Theories
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.
