332 Male volunteer via newspaper ad.

15 chosen for ranges of age, social class, ethnicity.

They had to go through a three phase screening which included:
Psychometric tests- to measure personality, emotions and intelligence
Full weekend assessment- conducted by psychology
Medical, character reference and police checks

They were divided into 5 groups of three matched for personality, out of each group one was randomly selected to be a guard and the other two were prisoners.

Independent Variables

Day 1 Permeability- ppcs were told that the guards were selected on specific traits
                            such as reliability, trustworthiness and initiative, and that  these may
                            have been missed in some prisoners, thus a promotion had become available.

Day 3 Legitimacy- After the one and only promotion took place, PPC's were then informed that in                             fact there was no difference in qualities between guards & prisoner. This meant                             that what was previously thought to be based on qualities now seen to be                                     random, the groups had become impermeable (unmovable)

Day 5 Cognitive Alternatives - A new prisoner was introduced because of his experience as a trade                                            union official. It was expected that he would introduce a new                                                       alternative plan of action based on negotiation and equal rights. He was                                        also expected to hav e the skills necessary to organise groups that                                                would allows prisoners to turn on the guards to see a way of acheiving                                         more equality.

Day 6

The guards had been overthrown by day 6, and it had been decided that a self-governing commune was to be created. Some former prisoners and guards attempted to impose much harsher rules on the others which lead to the experiment being cut short as it would have went on to break ethical guidelines.

Reicher and Haslam

-Both argued that the guards failed to identify with their roles, making them reluctant to impose their authority and lead to them being overcome by the prisoners
