Procedure
Type of experiment and design
Lab experiment and independant group design
Procedure
Sample size
70 adults
29 male
41 females
ages 20 to 81
Procedure
What sampling method was used
Volunteer sampling
Procedure
What were some ethical guidlines Burger used to protect his participants
Maximum V was only 150V instead of 450V
Participants were given 3 reminders that they had a right to withdraw
Participants debriefed immediatly after experiment ended
Procedure
When did the experiment stop
When the participants refused to continue or they administered the final 150V shock
Findings
Findings of obedience rates compared to milgrams
70% went to 150V compared to 82.5% in Milgrams
Findings
Obedience rate different gender
Women 72.7% pressed 150V
Male 66.7% pressed 150V
Conclusions
Findings show Milgrams results were not era bound nor was there a significant difference of obedience in males and females
Strength internal validity
None of the participants had any knowledge of Milgram’s original study
Strength internal validity
How did Burger make sure participants weren’t aware of Milgram’s study
Burger asked if participants took 2 or more psychology classes, thoe who did were excluded from the study
Strength internal validity
How can removing participants who were aware of Milgram’s study be good for validity
It decreases demand characteristics and increases internal validity
Strength of generalisability
Burger used 70 participants while milgram used 40.
Burger covered a wider age range than milgram and used females in his experiment where as Milgram’s were all male
Weakness of ecological validity
Milgrams study was critisied for lacking ecological validity
Weakness of ecological validity
Why was milgrams study critisied for ecological validity
Tsk is artificial, teachers aren’t asked to deliver electric shocks to learners - this same criticism applies to burgers study
