ABSTRACT
This chapter explores some of the key principles in group psychology, in particular focusing on how we interact with one another. Psychologist Holly Arrow and colleagues argue that another way of discriminating between groups is to consider common bonds versus common identity groups. The former are based on interpersonal relationships, while the latter rely on how much one is attached to the concept of the group itself. Many groups which we are a part of have existed since long before we were born, and will continue to exist long after we have died. The idea of such a group life cycle is typically perceived as involving 'forming, norming and storming'. One of the key ways in which groups generate shared understanding and influence group members is through social norms. Social norms can cover both attitudes and behaviour, and are usually something that we will be reasonably conscious of.
