Social perception  
Biases in physical object perception can lead to errors (e.g., optical illusions}. Biases in social perception likewise lead to errors (e.g., underestimating the role social factors and overestimating the effect of personality and attitudes on behavior).

Argued that the order people put on their perceptions followed the rule of psychological balance. positive and negative sentiments need to be represented in ways that minimize ambivalence and maximize a simple, straightforward affective representation of the person. 

Initiation rites improve group evaluations
Existing groups don’t let others join for free: the cost is sometimes monetary, sometimes intellectual, sometimes physical—but usually there is an initiation rite, even if it’s well disguised.

Aronson and Mills (1959) tested the effect of initiation rites by making one group of women read passages from sexually explicit novels. Afterwards they rated the group they had joined much more positively than those who hadn’t had to undergo the humiliating initiation. So, not only do groups want to test you, but they want you to value your membership.

Herbert Blumer
(1900 – 1987)
Symbolic Interactionism
Interaction has a role in the formation of meanings for individuals.  Three core principles: (meaning, language and thought) lead to conclusions about the creation of a person’s self and socialization into a larger community (Griffin, 1997).

The inspiration for this theory came from John Dewey, who believed that human beings are best understood in a practical, interactive relation to their environment.

Conformity experiments
Showed that social pressure can make a person say something that is obviously incorrect. Laboratory studies showed that under certain circumstances, a large percentage of people will conform to a majority position even when the position is clearly incorrect.  seminal studies on the primacy effect and halo effect, and helped inspire Stanley Milgram’s research on obedience to authority.

1951: Asch’s classic experiment on conformity:
Subjects:  7-9 subjects
One (naive) subject remained unaware of study’s purpose while other participants collaborated with the researcher.

Subjects were asked to compare three line segments and say which one matched a standard.
The collaborators in the group deliberately gave false answers [unanimously] on some trials in front of the subject.

Result:  In many cases, the naive subject gave an obviously wrong answer that matched the response of the other subjects, even though it contradicted the subject’s own initial judgment.

Conclusions: Conformity increases proportional to the number of people who agree.
Even one dissenting vote decreases conformity If a dissenter appears in the group, most subjects are “freed” from the conformity effect. When a single individual stands up, others feel released from group think and are free to follow their conscience.  This also applies to the Bystander effect

Muzafer Sherif 
(1906-1988)
Robbers’ Cave Experiment 
[with wife Carolyn Sherif]
Boys were divided into two competing groups to observe how hostility and aggression would emerge through competition over limited resources. Later, the groups were remixed and identity and loyalty changed. Inclusve group identification occurred when boys banded together against the “authorities.” Findings indicated that group cohesion and identification can be situational.

(1919-1989)

Cognitive Dissonance Theory
According to Festinger’s Cognitive Dissonance theory, people seek to avoid discrepancies between their attitudes and their actions, because they produce unpleasant feelings such as guilt, discomfort or confusion. In the attempt to reduce dissonance and to achieve cognitive consistency, people will seek to change either their attitudes or behavior in order to conform, often without reflecting their actual feelings. Often changing an attitude is easier than changing a behavior and the individual rationalizes the newly acquired view by discounting the earlier view. 

Classic cognitive dissonance experiment
Subjects were asked to perform a boring task. They were divided into 2 groups and given two different pay scales. At the end of the study, some participants were paid $1 to say that they enjoyed the task and another group of participants was paid $20 to say the same lie. The first group ($1) later reported liking the task better than the second group ($20). People justified the lie by changing their previously unfavorable attitudes about the task

Henri Tajfel 
(1919-1982)
Picture
Social Identity Theory
The desire to form and join social groups is extremely powerful and built into our nature. Groups help us develop our social identity, which contribute to our sense of self. People form and join groups  (1971)  

Minimal groups paradigm 
Boys who were strangers to each other were given only the slightest hint that they were being split into two groups. Even without knowing or seeing who else was in their group they favored members of their own group over the others. Group behavior, then, can arise from almost nothing.

Clark' Doll Experiment
Kenneth Clark and his wife Mamie conducted research suggesting that Black children preferred to play with White dolls, a result that the U.S. Supreme Court later cited as evidence that segregation "generates a feeling of inferiority... that may affect the childrens' hearts and minds." He was also the first African American to be elected President of the American Psychological Association.

In 2006 filmmaker Kiri Davis recreated the doll study and documented it in a film entitled A Girl Like Me. Despite the many changes in some parts of society, Davis found the same results as did the Drs. Clark in their study of the late 1930s and early 1940s.


Stanley Milgram 
(1933-1984)

Godfather of modern social psychology.
1963: Milgram’s classic Behavioral Study of Obedience. 
Subjects:  2 people
  • 1 collaborator (learner)
  • 1 naive subject (teacher)
The collaborator pretends to be a learner, and is taken into a room and hooked up to electrodes. The teacher is set up at a machine that he/she is [falsely] told generates shocks, voltage labels ranging from low to “danger - severe shock”. The teacher is instructed to deliver a shock each time the “learner” makes a mistake and to increase the voltage each time.

Result:  65% complied until the end of the experiment
Although the teachers felt distressed by the apparent suffering of the learner, most of them continued to raise the intensity of electrical shock until the “danger” level, at the urging of the experimenters.
When surveyed prior to the experiment, most teachers said they would stop at the first indication of pain. They were surprised by their own behavior.

Stanford Prison Experiment 1972: 
The Power of Social Roles
An example of how social environments can alter the behavior of “normal” citizens can be seen in the classic 1977 experiment conducted by Stanford University psychologist Philip Zimbardo.  The experimenter randomly divided participating students into “prisoners” and “gatekeepers” and instructed them to play their roles accordingly.  What transpired in a few days frightened the students and Zimbardo himself.  Most “gatekeepers” started treating their fellow students, who played the role of prisoners, with sadistic cruelty. And most of the “prisoners” showed signs of learned helplessness or responded with defiance. The results of this experiment and subsequent research demonstrate that people who are not ordinarily cruel can be influenced to act in sadistic ways, through a simple change of social role and position.
