- what is a group?
- 2 or more people having awareness of shared meaning & identity
- behaviour in accordance with shared values
- task performance function (task group): can do tasks that individuals cannot do by themselves
- socio-emotional function (intimacy group): social support
- social identity function (social category): social identity - defines “location in society” +
social meaning
- social brain hypothesis
- group & brain = evolutionary linked
- group living - evolutionary pressure for brain evolution = made possible the maintenance of
larger group
- neocortex size = correlated w average group size of the species
- ^ larger relative to the rest of the brain, esp higher order information processing
- properties & structures of groups
- group properties:
- norms - attitudinal & behavioural pattern characteristic of a group (agreed upon standards
of behaviour) - causes uniformity
- descriptive (what people DO do & think) & injunctive (what people SHOULD do &
think)
- norms become apparent when violated
- shared ideologies, values & attitudes
- shared frame of reference; Sherif’s auto-kinetic effect experiment - conformity
- cohesiveness - “a force field” (Lewin) keeping individuals in the group
- attractiveness of group & group members (pro)
- interdependent for individual goals (pro)
- members tend to follow group norms & stay in group (cons)
- intra-group differentiation:
- roles: who does what, when? division of labour
- expectation of behaviour
- self-definition within group
- e.g. The Stanford Prison Experiment

Document Summary
2 or more people having awareness of shared meaning & identity. Task performance function (task group): can do tasks that individuals cannot do by themselves. Social identity function (social category): social identity - defines location in society + social meaning. Group living - evolutionary pressure for brain evolution = made possible the maintenance of larger group. Neocortex size = correlated w average group size of the species. ^ larger relative to the rest of the brain, esp higher order information processing. Norms - attitudinal & behavioural pattern characteristic of a group (agreed upon standards of behaviour) - causes uniformity. Descriptive (what people do do & think) & injunctive (what people should do & think) Shared frame of reference; sherif"s auto-kinetic effect experiment - conformity. Cohesiveness - a force field (lewin) keeping individuals in the group. Attractiveness of group & group members (pro) Members tend to follow group norms & stay in group (cons)
