cooperation & competition/group dynamics

group dynamics - refers to the processes that occur within the group that we belong to (ingroup) & the interactions between ingroup & outgroup (inter-group processes)

important to remember that a group’s behaviour is influenced by the ppl within the group

  • but some ppl believe that individuals’ behaviour changes once they’re in a group

  • so group behaviour is the result of interaction between group members & the importance they provide to group’s membership

group mind - is a phenomenon where the power of the group is so strong that it shapes individual’s behaviour & causes them to engage in actions and behaviours they previously never would hv engaged with

  • everyone basically acts as one, and each group member loses individuality


being part of a group could also free members from social responsibility & the need to act in a socially responsible manner


social exchange theory - ppl want to join groups that provide them with maximum reward

past experiences are also a factor in choosing ingroup - positive experiences with similar groups in the past, would encourage individuals to select similar groups in the future

choosing groups is important to us, cuz groups construct our identity & self-esteem


if goals aren’t shared between groups, competition & conflict are more likely to occur


realistic group conflict theory - inter-group conflict can arise when groups hv conflicting goals & are competing for limited resources

  • if one group succeeds in obtaining the resources, the other group is affected

  • if groups are pursuing a subordinate (common) goal & they need to cooperate in order to succeed, this cooperation can help overcome prejudice & discrimination


theory of group position - when members of an ingroup believe they’re entitled to certain resources & they perceive an outgroup trying to make claims to these resources, conflict & competition can arise


social dominance theory - i think its smthg about how ppl want to be able to dominate a society

terror management theory - can textbook for this


cooperation - refers to groups or individuals working together for mutual benefit

  • both parties win in some way

  • built on communication & trust

competition - refers to groups or individuals working against each other for selfish motives

  • there is a clear winner & a clear loser (victory of one party comes at the expense of another party)

  • could involve competition over limited resources


theories of cooperation

Kin Selection Theory - individuals are more likely to cooperate with family than anyone else

Reciprocal Altruism theory - individuals may expect repayment if they help someone “i scratch your back you scratch my back” kind of mindset

Mutualistic collaboration - individuals cooperate for mutual benefit


people may be collaborative because they need to do so in order to survive

  • collaborating with others means individuals can access resources or information they may not be able to, and therefore would have a greater chance of survival
