Zimbardo's goals[ edit ] The archived official website of the Stanford Prison Experiment describes the experiment goal as follows: We wanted to see what the psychological effects were of becoming a prisoner or prison guard.
By Saul McLeodupdated Purpose of the Study Zimbardo and his colleagues were interested in finding out whether the brutality reported among guards in American prisons was due to the sadistic personalities of the guards i.
For example, prisoner and guards may have personalities which make conflict inevitable, with prisoners lacking respect for law and order and guards being domineering and aggressive. Alternatively, prisoners and guards may behave in a hostile manner due to the rigid power structure of the social environment in prisons.
Zimbardo predicted the situation made people act the way they do rather than their disposition personality. Procedure To study the roles people play in prison situations, Zimbardo converted a basement of the Stanford University psychology building into a mock prison. He advertised asking for volunteers to participate in a study of the psychological effects of prison life.
The 75 applicants who answered the ad were given diagnostic interviews and personality tests to eliminate candidates with psychological problems, medical disabilities, or a history of crime or drug abuse.
Participants were randomly assigned to either the role of prisoner or guard in a simulated prison environment. There were two reserves, and one dropped out, finally leaving ten prisoners and 11 guards. Prisoners were treated like every other criminal, being arrested at their own homes, without warning, and taken to the local police station.
Here the deindividuation process began.
When the prisoners arrived at the prison they were stripped naked, deloused, had all their personal possessions removed and locked away, and were given prison clothes and bedding.
They were issued a uniform, and referred to by their number only. The use of ID numbers was a way to make prisoners feel anonymous.
Each prisoner had to be called only by his ID number and could only refer to himself and the other prisoners by number. Their clothes comprised a smock with their number written on it, but no underclothes.
They also had a tight nylon cap to cover their hair, and a locked chain around one ankle. All guards were dressed in identical uniforms of khaki, and they carried a whistle around their neck and a billy club borrowed from the police.
Guards also wore special sunglasses, to make eye contact with prisoners impossible. Three guards worked shifts of eight hours each the other guards remained on call. Guards were instructed to do whatever they thought was necessary to maintain law and order in the prison and to command the respect of the prisoners.
No physical violence was permitted. Zimbardo observed the behavior of the prisoners and guards as a researcherand also acted as a prison warden. Findings Within a very short time both guards and prisoners were settling into their new roles, with the guards adopting theirs quickly and easily.
Asserting Authority Within hours of beginning the experiment some guards began to harass prisoners. More importantly, they provided a regular occasion for the guards to exercise control over the prisoners.THE STANFORD PRISON EXPERIMENT: of the experiment by Professor Zimbardo, interspersed with sound effects from the study and other sources.

The Stanford Prison Experiment (SPE) was a social psychology experiment that attempted to investigate the psychological effects of perceived power, focusing on the struggle between prisoners and prison caninariojana.com was conducted at Stanford University between August 14–20, , by a research group led by psychology professor Philip Zimbardo using college students.

Some took the part of prisoners and some the part of the guards.
