40 American male pps (supposedly for a study on memory) - each pp draw lots for their role
a confederate was always the 'learner' while the true pp was the 'teacher', and an 'experimenter' (confederate) wore a lab coat
teacher could hear but not see the learner
Milgram's obedience baseline procedure
the teacher had to give the learner an increasingly severe electric 'shock' each time he made a mistake on a task
the shocks increased in 15-volt steps up to 450-volts
the shocks were fake but the shock machine was labelled to make them look increasingly severe
if the teacher wished to stop, the experimenter gave a verbal 'prod' to continue
baseline findings
12.5% (5 pps) stopped at 300 volts
65% continued to 450 volts (highest level)
observations (qualitative data) - pps showed signs of extreme anxiety
3 had "full-blown uncontrollable seizures"
before the study Milgram asked 14 psych students to predict how they thought the naiive pps would respond
they estimated no more than 3% would continue to 450 volts (=> baseline findings were unexpected)
after study, pps were debriefed, follow up questionnaire showed 84% were glad they participated
baseline conclusions
we obey legitimate authority even if that means that our behaviour causes harm to someone else
certain situational factors encourage obedience
strength = replications have supported findings
French TV documentary/game show = contestants were paid to give (fake) electric shocks when ordered by the presenter to other pps (actors)
80% gave the maximum 460 volts to an apparently unconscious man - their behaviour was like that of Milgram's pps (eg many signs of anxiety)
=> supports milgram's original findings about obedience to authority
limitation = study lacked internal validity
Orne and Holland = argued that pps guessed the electric shocks were fake, so they were 'play-acting'
this was supported by Perry's discovery that only half of the pps believed the shocks were real
suggests that pps may have been responding to demand characteristics
strength = supporting study
Sheridan and Kings pps = gave real shocks to a puppy
54% of males and 100% of females delivered what they thought was a fatal shock
suggests the obedience in Milgram's study might be genuine
limitation = findings are not due to blind obedience
Haslam et al = found that every pp given the first 3 prods obeyed the experimenter but those given the 4th prod disobeyed
according to social identity theory, the first 3 prods required identification with the science of the research but the 4th prod required blind obedience
shows that findings are best explained in terms of identification with scientific aims and not as blind obedience to authority
extra evaluation = ethical issues
pps were deceived (thought shocks were real) - Milgram dealt with this by debriefing pps
Baumrind = felt this deception could have serious consequences for pps and researchers (eg no informed consent possible)
=> research can damage the reputations of psychologists and their research in the eyes of the public
