What is Social Psychology
An attempt to understand and explain how the thought, feeling, and behavior of individuals are influenced by the actual, imagined, or implied presence of others
-
What makes social psychology a science?
the use of systematic methods
-
What is a theory
An organized system of ideas that tries to explain why two or more events are related
-
What makes a good hypothesis
- specific statements about a behavior
- they can be tested
- test a small amount of evidence related to the theory
-
What are the social psychology methods
- correlational method
- experimental method
-
correlational method
- The method whereby two or more variables are systematically measured and the degree of covariation between them is assessed
- ex.Does satisfaction with SUNYA increase with GPA?
-
types of correlational methods
- positive correlation (height and shoe size)
- negative correlation (year in school and writing home)
- no correlation (year in school and height)
-
What is good about correlational research
- easy to collect data
- easy to quantify the results
- easy to communicate the results to the public
-
What is bad about correlational research
results are easy to misinterpret
-
how can correlations be misinterpreted
- A may seem to cause B but instead B causes A
- Using condoms predicts STDs or STDs predicts use of condoms
- Interpret: A > B
- In truth: B > A
- Third variables
- Interpret: A > B
- In Truth: A < C > B
-
experimental method
- Research designed to examine the cause-effect relationships between variables
- The experimenter randomly assigns participants to different levels of an independent variable and then tests its influence on a dependent variable
-
independent variable
the experimental variable that the researcher manipulates
-
dependent variable
the experimental variables that is measured because it is believed to depend on the manipulated changes in the independent variable
-
random assignment
everyone in the population has an equal chance of taking part in any condition of an experiment
-
Kitty Genovese
brutally murdered on the streets near her house, none of the apartment residents called the cops
-
Latané and Darley (1968)
- theory: diffusion of responsibility caused lack of helping
- hypothesis: as the number of bystanders increases, the amount of helping should decrease
-
External Validity
the extent to which results from the study can be generalized
-
two types of realism
- mundane realism
- experimental realism
-
mundane realism
Does this study "look like" the real world
-
experimental realism
does this study "feel like" the real world
-
Was the Darley and Latané more mundane or experimental realism
experimental, felt real but did not look like the real world
-
how do you attain internal validity
- nothing other than the independent variable changes from condition to condition
- requires: random assignment to condition, identical procedures across conditions
-
what is social influence
- "pressures" created by other people
- is the attempt to change the attitudes or behaviors of others in a particular direction through the exercise of social power
-
forms of social influence
- conformity
- compliance
- obedience
-
conformity
the pressure to be similar to otheres
-
compliance
the pressure to yield to an appeal by others (persuasion)
-
obedience
the pressure to yield to a command by others
-
why do people bend to social pressure
- normative influence
- informational influence
-
normative influence
- conformity to gain a reward or avoid punishment - need to be accepted
- follow social norms because it is expected from us
-
informational influence
- conformity due to a desire to gain information (ambiguous situations)
- ex. is that scream someone getting mugged or fooling around
-
norm
social rule or standard telling individuals how they should or should not behave
-
descriptive norm
a norm that simply indicate what most people do in a given situation
-
injunctive norm
norms specifying what ought to be done - what is approved or disapproved behavior in a given situation
-
private acceptance
conforming to other people's behavior out of genuine belief that what they are doing or saying is right
-
public compliance
conforming to other people's behavior publicly, without necessarily believing in what is being said or done
-
what increases conformity pressure
- size (up to a point)
- cohesiveness
- lack of social support
- unanimity
- status within the group
-
Sherif's autokinetic effect
- visual illusion
- how much did the light move
- individually, people had wildly divergent opinions
- when people were put together and had them announce how much the light moved, everyone agreed on a standard established by the group
-
ambiguous reality
- look to group to help them define reality
- example of informational influence
- private acceptance; most people denied that the group played any role at all
- keep norms even when alone
-
when is informational influence the strongest?
- when the situation is ambiguous
- during crisis
- when others are experts
-
resisting conformity
- related to our values and self-concept
- desire for personal control
- ex. if your parents don't like your partner, you may like them more
-
obedience to authority
the most coercive type of social influence
-
how many people reached the 450v in shocks for milgram experiment
- 62.5%
- 80% continued after first plea
-
variation with three teachers in milgram experiment
- one ally quits at 150
- one ally quits at 210
- one continues to 450
- percentage: 10%
-
variation when experimenter leaves room and 2nd teacher comes in a introduces 15-shock increment
percentage: 20%
