Data collection process/ type of data collected

Quantative: level of voltage Qualitative: signs of anxiety, body language, and nervous giggling. Both

the 4 IV

-type of victim "drunk or ill"

-race of victim    "black or white"

-behavior of a "model"    "model really close or too distant to help/early or late to help"

Conspecific definition 

-member of the same species; in this study the conspecific refers to the chimpanzees

what were the risks about the sample in pavilion et al

thay could of dubble dipped in the sample because of the same route they took

300

Research Method

Not a true experiment, Quasi experiment

300

Dependent Variables (DV)

-level of bystander helping

-time taken for 1st passenger to help

-total number of passengers who helped

-race, gender, and location of carriage

-whether people moved away/any comments made

-which victim helped the most

300

Independent Variable (IV)

300

pro social behavior and instrumental helping 

yamamoto et al

300

what ethics did Milgram experiment brake 

deception 

400

Results characteristics

mean voltage 368v    all p's gave al least 300v

65% gave max shock of 450v


400

Conclusions

-no diffusion responsibility found

-someone who appears drunk is LESS likely to receive help than someone ill

-men more likely to help

-drunk less helped due to higher chance of embarrassment, disgust, harm

-women less likely due to strength or roles

-cost-benefit model discovered

400

Dependent Variable (DV)

-targeted helping behavior (providing the correct tool)

400

behavior and emotions  can be influenced by other individuals

was the sample in milgram et  al generalizable 

no, its not its all men from the same area

500

Conclusions

-individuals are much more obedient towards authoritative figures than we may expect

-despite high levels of obedience, people find the experience stressful 

500

Sample

estimated about 4,450 people

-45% black and 55% white

-average number in car was 43

-average number in critical area was 8.5

-opportunity sample

500

Conclusions

-when chimps are able to see the situation of a conspecific, they can offer targeted helping behavior (often by direct request not altruistic behavior)

-chimps can understand conspecifics goals

500

behavior and emotions can be influenced by social context
