Description
Social Psychology Part 2 Lecture Notes - Social Influence - The Nature of Groups o Group living is an important part of human evolutionary history o Increased safety o Cooperation o Help childrearing o Definition of a group:  Two or more people who interact and are interdependent (shared goals cause them to rely on one another) - Groups and Performance o How does the presence of others affect performance? o Triplett (1897-1898)  Examined bicycle competition times for those alone and with  Observed performance of simple tasks alone and with others (fishing reel studies) o Social facilitation: an increase in a person’s performance of a task because of the presence of others o Social Interference (Social inhibition): a decline in a person’s performance of a task because of the presence of others o How can Social facilitation and social interference both occur? - The Zajonc Solution: Social Facilitation - Cockroach Studies on Social Facilitation o Cockroaches run away from lights o Two independent variables:  Maze: simple vs. complex  Social condition: alone vs. with another cockroach vs. with an “audience”  Complex maze = social interference  Simple maze = social facilitation - Groups and Performance o But what happens when we perform a task with others?  Pulling a rope or pushing a cart?  Individual output decline when working together  Why?  Less individual effort? Poor group coordination? o Ingham et al. (1974)  All participants blind-folded and told to pull rope as hard as they could  Assigned to one of two conditions:  Thought they were pulling with others (which they weren’t)  Thought they were pulling alone (which they were)  Results: pulled ~20% harder when pulling alone - Social Loafing: a group produced reduction in individual output on tasks where contributions are pooled o How can social loafing be reduced?  Believe performance can be identified  Believe own efforts necessary for successful outcome  Group expects to be punished for poor outcome  Task is meaningful/important  Group is small  Group is cohesive - Although everyone is vulnerable to social loafing, some people less prone to it than others: high on conscientiousness - Deindividuation o How can we explain “mob behaviour”? o Deindividuation: the loss of a person’s sense of individuality and the reduction of normal constraints against deviant behaviour  Arousal
