Document Summary

Intergroup: processes that happen between groups of people. Turner states: a group exists when two or more individuals perceive themselves to be members of the same social category. Rupert brown: a group exists when two or more people define themselves as members of it and when its existence is recognized by atleast one another. Social facilitation: when people do better on a task in the presence of others than when they are alone. Presence of people can lead to poorer performance. People who perform a difficult task do more slowly in front of other people than when they are alone this is social inhibition. Social inhibition: when people do worse on a task in presence of others than when they are alone. Mere presence of people increases our physiological arousal (energy, excitement). This arousal enhances whatever a persons dominant tendency is on a particular task. High arousal therefore leads to better performance on tasks that are simple/well learned.
