Document Summary
Psyc 1103 lecture 26: group influence, social identity. Deindividuation : loss of perceived responsibility and identity in a group setting. Why individuals may perform destructive acts in a group setting that they would not otherwise do alone. Social contagion : the spread of behavior, thoughts, ideas, etc. Groupthink : the process in which individuals are more motivated by sense of group cohesion (trying to avoid conflict or disagreement), and desire for agreement and group harmony. Overconfidence, excitement about coming to an idea and making progress. Ignoring counter-arguments or problems with the idea. Being in a group presents group pressure for each individual to conform (reduces chance of speaking up) Social facilitation: performance is enhanced when in the presence of others. Due to increased arousal when in front of others. Applies more to well-learned tasks (when an individual is already skilled in the task) Social loafing: exerting less effort when in a group.
