Final answer:
The Sherif study, known as the Robbers Cave experiment, supports informational social influence. It involved creating two groups of boys, observing their intergroup conflict, and demonstrating the power of informational social influence when they worked towards a common goal.
Step-by-step explanation:
The Sherif study that supports informational social influence is the Robbers Cave experiment conducted by Sherif, Harvey, White, Hood, and Sherif in 1961. This study sought to understand the effects of intergroup conflict and cooperation. The experiment involved creating two groups of boys and observing how the groups formed distinct identities and engaged in conflict.
The study found that when the two groups were brought together and given a common goal, such as fixing a water supply issue, they were able to overcome their conflict and cooperate. This demonstrated the power of informational social influence, as the boys relied on the group's information and learned from their behaviors to work towards their common goal.
The Sherif study is a classic example of informational social influence, showing how people conform and rely on the group's information in ambiguous situations to influence their behavior.
