burger Flashcards
Issue and debate: How has psych knowledge dev over time? (link to burger)
Milgrams study was controversial due to its ethics. ppts in his study under high levels of stress. 150v crucial point- where learner protests and demands to be realised (point from pilot study where they guessed how far they would go) 6/14 ppts who stopped before 450v stopped at150v. 79& of the people who went past 150v went all the way to the end suggests knowing what people do at 150v predicts continuation. Burger also points out after ppts decides whether to go forward from 150v when they stop the study ppts still experience extreme stress which Milgrams ppts exp in the later part
What was the aim of Burgers study?
To find out if the same results as Milgram’s 1963 study re-occur when the study is replicated with modern participants in 2009. Also, to see if personality variables like empathy and locus of control influence obedience. Finally, to see if the presence of a disobedient “model” makes a difference to obedience levels.
What was the IV in Burgers study?
Base condition compared to model refusal condition
What is the independent measure?
Independent group design- compares 2009 ppt with 1960s ppp and compares control group with disobedient model group
What was the DV in Burgers study?
Obedience is measured by how many volts the last shock to be delivered was - before the participant refused to go on, exhausted all the “prods” or reached 150V (whichever happened first)
What was Burgers sample and sampling technique?
Volunteer sampling, ad in paper and online, ppts paid $50 before study took place,(more ppt before screening + psych students immediately excluded) 29 m and 41f age range 20-81 and mean age of 42.9 and range of occupations and ethnicities
Key differences between Burgers and Milgram’s study
Complicated screening which improved ethics, male and females, winder age range and ethnicities, Milgram gave a sample shock of 45v wheras Burger gave 15v
Describe Burgers screening process
Psych students x because validity of Burgers results would be affected as they would know what Milgram found and may alter their behaviour. Questionnaire about Ppts physical, mental health and childhood trauma 30% excluded. Questionnaires demographic, empathy, locus of control, anxiety, control, depression. Then a structured interview- neuropsychiatric interview
Procedure of Burgers study (baseline)
Initial set up same between 2 conditions, told they could withdraw and keep money, told it was to ‘investigate the effect of punishment on learning’, drawing of rigged lots, both sign consent forms. Learner was put into adjacent room and teacher witnessed electrode on learners wrist and told to read 25 words and each wrong answer will get a shock and increases with every wrong answer. Confederate reveals they have a heart problem like variation 5. Sample shock of 15v and same 4 verbal prods
Results of Burgers BC
75v pre-recorded grunts heard, 150v pre-recorded learner voice says ‘Get me out of here please my heart is bothering me’. 12 ppt/30% stopped at 150v and 28 ppts/70% said they would continue. Obedience in Milgram’s V5- 82% no statistical difference between this condition and Milgram’s similar condition
Procedure in modelled refusal condition
2 confederates, one is teacher 1 and other is learner, ppt is teacher 2. Teacher 1 takes lead same audio script from baseline. At 75v grunting heard teacher 1 hesitates, 90v teacher 1 says ‘ Idk about this’, experimenter uses a prod and teacher 1 refuses and pushes a chair back and teacher 2 carries on
Results of modelled refusal
11ppts /36% stopped at 150v , 19ppts /63% prepared to continue. No statistical difference between 2 conditions
Individual differences results;
-Gender= none
-Empathy=Higher empathy more reluctance to continue, didn’t decrease obedience
-*hypothesis high internal= decrease obedience, correlation only in base condition. Presence of dissenting model reduced effect perhaps triggered a me vs him between ppt and confederate teacher
Burgers conclusions:
Milgram’s results still stand- people are influenced by situational factors to obey authority figure even if it goes against their morals. Burger makes assumption if they’re willing to go past 150v they would go to 450v. Model refusal results similar to BC against SIT suggest impact of authority figure lessened if teacher had an ally
Ethics in Burgers study
2 step screening process excluding vulnerable people ,told twice they could withdraw and keep money, monitored by a clinical psychologist who was told to end the study if any signs of excessive stress and approved by Santa Clara uni review board
