the 3 situational variables are: proximity, location and uniform.
PROXIMITY - SAME ROOM VARIATION:
teacher and learner are in the same room - original they could not see one another, only hear eachother.
obedience rate = 40%.
why? - being able to see the learner humanises them, makes the decision more morally conflicting.
PROXIMITY - TOUCH PROXIMITY:
teacher has to force the learner's hand onto an electroshock plate when they didn't answer a question, or got it wrong.
obedience rate = 30%
why? - they will physically feel any resistence made by the learner, more of a forceful action.
PROXIMITY - ORDERS OVER THE PHONE:
experimenter leaves the room, gives intructions over the phone.
called remote instruction.
often gave weaker shocks than they were meant to or pretended to give shocks.
obedience rate = 20%
why? - less intimidated by an authoritarian if they cannot see them.
LOCATION VARIATION:
changed the setting from a university to a run down building.
obedience rate = 47.5%
why? - yale gives a higher sense of authority.
UNIFORM VARIATION:
experimenter is called away by a phone call, role of experimenter was taken by an 'ordinary member of the public' played by a confederate - wearing everyday clothes.
obedience rate = 20%
why? - uniform itself is a symbol of authority.
STRENGTH - RESEARCH SUPPORT:
Bickman.
has 3 confederates dress in 3 different outfits, stand in the street and ask passers to perform tasks like picking up litter.
outfits: jacket and tie, milkman's outift and security guard uniform.
passers were twice as likely to obey security guard than jacket and tie.
STRENGTH - CONTROL OF VARIABLES:
Milgram's variations is that he changed one variable at a time, like proximity to see the effect on obedience.
everything else in the study remained the same over and over.
it means we can be sure that the change in situational variable was the factor that affected obedience.
STRENGTH - CROSS-CULTURAL REPLICATIONS:
Miranda et al - obedience rate over 90% in spanish students.
suggests Milgram's findings are not limited to just americans.
