PSYB10 – Lecture 6 notes
-How ppl around us actually affect us
-different types of groups: social, and nonsocial.
-group members should have the ability to interact w/ each other
-interdependence: need to in some ways have some kind of shared goals, shared space, in a
way in which you need each other to depend on one another. Nonsocial group -> social
group; ex. standing in line for a book, not talking to anyone, but suddenly someone does
smthg (social object involved), and then the group interacts.
-groups have social norms to guide behaviour
-groups have well-define social roles
-vary in level of group cohesiveness
-Social norm: prescription for your behaviour (naked guy)
-Social roles: a group’s expectations for the behaviour and responsibilities of various subgroups of its
-constitute a strong situation that could bowl over an ind’s personality (prison/guard exper)
-Group cohesiveness: the degree to which a group IS or IS PERCIEVED TO BE close knit and similar to
one another (ex. sorority/frat members)
-what does cohesiveness do > promotes liking and ingroup favouritism
-outsiders: ^ stereotyping to the group.

grace. While other prisoners did push ups.
-prisoners got so pissed and started to rebel and breaking down emotionally forcing them to release
them (4 of them) and others started becoming model prisoners. -there were 3 types of guards > sympathetic, tough but followed rules, and guards that humiliated
