Chapter 12 - Social psychology Flashcards
Social brain hypothesis
Humans belong to the order primates, which includes great apes and monkeys
According to the social brain hypothesis, brain hypothesis, primates have large brains in particular, large prefrontal cortices because they live in complex social groups that change over time
People are especially likely to organise themselves into groups when two conditions are met. What are they?
Reciprocity
Transitivity
Reciprocity
Meaning that people treat others as others treat them
Transitivity
Pople generally share their friends’ opinions of other people
Outgroup homogeneity effect
The tendency to view outgroup members as less varied than in-group members
Social identity theory
The idea that in-groups consists of individuals who perceive themselves to be members of the same social category and experience pride through their groups membership
In-group favouritism
The tendency for people to evaluate favourably and privilege members of the in-group more than members of the outgroup
Minimal group paradigm example
Turner (1979) randomly assigned volunteers to two groups using meaningless criteria such as flipping a coin
Why do people favour members of their own groups?
One possibility is that people who work together to keep resources within a group and deny resources to outgroup members have a selective advantage over these two are willing to share with outgroup
Another possibility is that group membership is as important to us that we are willing to hurt people in outgroups as a way of signalling how much we value the people in our in-group
Brain activity associated with thinking about other people
The middle region of the prefrontal cortex, called the medial prefrontal cortex, is important for thinking about other people
Thinking about them generally or specifically, whether they are in in-groups or outgroups
When is the medial prefrontal cortex less active?
When people consider members of out-groups, at least members of extreme out-groups such as people who are homeless or drug addicts
Explanation for differences in the medial prefrontal cortex brain activity
One explanation for these differences in brain activity is that people see in-group members as more human than outgroup members
Risky shift effect
Group often make riskier decisions than individuals do
Group polarisation
The process by which initial attitudes of groups become more extreme over time
Groupthink
The tendency of a group to make a bad decision as a result of preserving the group and maintaining its cohesiveness
Especially likely when the group is under intense pressure, is facing external threats, and is biased in a particular direction
How to prevent groupthink
Leaders must refrain from expressing their opinions too strongly at the beginning of discussions
The group should be encouraged to consider alternative ideas, either by having someone play devil’s advocate or by purposefully examining outside opinions
What does Zajonc’s model predict?
That social facilitation can either improve or impact performance. The change depends on whether the response that is required in a situation is the individual’s dominant response.
If the required response is easy or well learned, so that the dominant reponse is good performance, the presence of others will enhance performance. If the required response is novel or less well learned, so that the dominant response is poor performance, the presence of others will further impair performance
Social facilitation
The idea that the presence of others generally enhances performance
Social loafing
The tendency for people to work less hard in a group than when working alone
Deindividuation
A state of reduced individuality, reduced self awareness, and reduced attention to personal standards
This phenomenon may occur when people are part of a group
Individuated
We walk around with a sense of ourselves as individuals who are responsible for our own actions
Conformity
The altering of one’s behaviours and opinions to match those of other people or to match other poles expectations
Normative influence
The tendency for people to conform in order to fit in with the group
Informational influence
The tendency for people to conform when they assume that the behaviour of others presents the correct way to respond
