Week 23: Social Thinking and People in Groups Flashcards
Groups
3+ people
- shared goals + needs
- permenant - familyy
- temporary - school team
- natural - family
- deliberate - employees
specific social norms in groups
- unwritten rules governing behaviour
- enhance survival/reproduction
- Can facilitate or inhibit various processes
Social Facilitation
Happens when people are working alone
* but in the presence of an audience
Performance is enhanced on simple, well-learned tasks
Diminished on novel, complex tasks
Triplett (1898)
Co-action effect
Cycling: Individual times slower than group times
He observed same thing with kids
reeling in fishing lines
*When people doing the same thing, most people perform faster
Limitation:
Sometimes we do worse in groups than alone
Zajonc (1965)
Dominant Response
Reformulation in terms of facilitation of one’s dominant response
Dominant Response Strong
- anything practiced and really well learned is a dominant response
Dominant Response Weak
- first time learner or less practiced
Yerkes-Dodson Law
Arousal due to mere presence of others affects performance
Dominant Response Strong will make us perform really well in presence of others
Dominant Response Weak will make us even more stressed and perform not well
*Optimal arousal is medium
* high will cause anxiety, stress
* low will cause boredom, sleepiness
Zajonc’s modified Yerkes-
Dodson Law
- Different types of tasks have
different optimal levels of arousal
ORIGINAL YERKES-DODSON LAW
- Optimal arousal actually on lower end when less practiced
- Optimal arousal actually on higher end when more practiced
Ex. Pool players example
- good players got better with audience
- bad players got worse with audience
Evaluation Apprehension - arousal
worried about other people judging our performance
Distraction - arousal
less focus on task, due to other stimuli
Competition - arousal
others doing same task effect our performance
Social Loafing
&
Diminished Performance
Happens when people are working together towards some goal
- The more people in the group, the less each individual contributes
Ringelmann’s (1880s)
research on pulling strength and diminished performance
Mechanism Question
- Coordination loss vs. loss of motivation?
participant pulling rope by themselves
IV - researchers would either be present not pulling rope (pretending to pull) or not present at all
DV - pulling power diminished
Diffusion of evaluation
people think their one individual self has less impact
How to deal with social loafing
monitor each individual output in the group
stats on who aloafs
men more than women
boring less than interesting tasks
strangers more than friends
individualistic cultures vs. collective cultures
Group think
Social cohesion is favoured over factual information
“Go along to get along”
Occurs when group is
- Homogenous
- Isolated from contradictory opinion
- Lead by directive leader
- High stress
- Poor procedures
Results in
- Perception of invulnerability
- Belief in correctness
- Elimination of dissenters
▪ Creates illusion of unanimity
- Self-censorship
- Mindguarding the leader
Titanic Situation
“Even God Himself would not sink this ship”
- Illusion of invulnerability
- Belief in correctness
- Elimination of dissenters (binocular guy continued his job without tool)
- Self-censorship
- Mindguards (people didn’t warn captain of shit going on)
Avoiding group think
- Impartial leadership
- Consulting outside sources
- Creating sub-committees
E.g. “red teaming” - Soliciting anonymous feedback
Group Polarization
“risky shift” phenomenon
- individuals after consulting with group would make more risky or extreme choices
- Enhancement of individual members’ initial
position
Positive (on its own) or negative
E.g. judges took extreme action in 30% of cases
when alone vs. in 65% when in group of 3
Myers & Bishop 1970
Test on Racial prejudice for group polarization
All students filled out racial attitude survey
First time: on their own
Then grouped together with similar scoring people
Second time: racial attitudes measured again
Less prejudice people became EVEN LESS so
More prejudice people became EVEN MORE so
Learning Objectives:
Define social psychology.
Review the history of the field of social psychology and the topics that social psychologists study.
Summarize the principles of social psychology.
Describe and provide examples of the person-situation interaction.
Review the concepts of (a) social norms and (b) cultures.
Kurt Lewin
Father of Social Psychology
*systematically and formally measure the thoughts, feelings, and behaviors of human beings
Leon Festinger
Wrote: Research Methods in the Behavioral Sciences
stressed the need to measure variables and to use laboratory experiments to systematically test research hypotheses about social behavior.
Adolf Hitler’s role in Social Psychology
Researchers wanted to understand how such extreme obedience and horrendous behaviors in his followers during the Second World War
Philip Zimbardo
Standford Prison Experiment
found that ordinary male college students who were recruited to play the roles of guards and prisoners in a simulated prison became so involved in their assignments, and their interaction became so violent, that the study had to be terminated early
*powerful role of the social situation on human behavior
John Darley and Bibb Latané
model that helped explain when people do and do not help others in need
