SOCIAL AREA: Piliavin et al. Flashcards
Piliavin et al.: Aims
- aimed to investigate what factors affected helping behaviour, including things such as race
Piliavin et al.: Sample
- opportunity sample
- 4450 people’s data analysed
- people travelling on the Harlem-Bronx train from 11AM to 3 PM on weekdays from April 15th to June 26th 1968
- 55% white and 45% black
Piliavin et al.: Procedure
- two female observers, a male model and victim boarded the train
- victim conditions either drunk or with a cane, and black or white
- model conditions either helping after 70s in critical area, 150s in critical area, and either displaying help in adjacent area after 4th or 6th station
- after one of these amounts of time occurred, the victim staggered and collapsed and remained motionless until they received help
- model only intervened if no ps helped within given time
- if model did assist they would depart the train to board another going in the opposite direction
Piliavin et al.: Quantitative results
- observers recorded what help was received, how quickly and how many helped
- 62/62 ‘cane’ trials had help
- 19/38 ‘drunk’ trials had help
- 90% of helpers were male, despite all victims being male
- 64% of helpers were white
Piliavin et al.: Qualitative results
- ‘It’s for men to help him’
- ‘I’m not strong enough’
- ‘You feel so bad that you don’t know what to do’
Piliavin et al.: Conclusions
- concluded that state of victim affected how likely people were to help him; many more people helped on cane trials than on drunk trials
Piliavin et al: Ethics
Deception: scenario was faked without telling participants
Not debriefed
Informed consent not given; didn’t know they were in a study
Withdrawal; not told they could withdraw, on a moving train, could only go to next carriage, may not be able to get through crowd, still not able to fully remove self from situation
Competence: researchers were students and ‘didn’t like’ doing the drunk experiment, hence why there were fewer trials
Confidentiality upheld, no names or photos released
Piliavin et al.: Internal Reliability
- set controls and layout of adjacent and critical area etc.
- however should have had same no. drunk and cane trials
Piliavin et al.: External Reliability
- over 100 trials; high
- 4450 ps, 80% of time got help; consistent result, same with cane trials; 62/65 received help
- sample large enough to confirm consistent effect (4450)
Piliavin et al.: Internal Validity
- weren’t aware of situation so reactions were genuine; not affected by bias or any sort
- likely they might have already seen trial during other journeys; demand characteristics
Piliavin et al.: External Validity
- low; large sample with different races and mix of genders but only in New York; know from Levine et al.’s research that NYC is not a helpful city so cannot be an overly accurate representation of helping behaviours across humans as a race, only in NYC
Piliavin et al.: Ecological Validity
- high as it was conducted on a public subway
- situation very feasible
- however, may well have seen study happen on another journey
Piliavin et al.: Ethnocentrism
- only conducted in NYC
- however NYC is a heterogenous city and 45% of ps were black
- different racial backgrounds but still same culture
Piliavin et al.: Areas and Perspectives
Social area: invesigating impact of other people on our behaviour and if likelihood of helping is affected by known witnesses to event (diffusion of responsibility)
Biological area: observation of an emergency will create an emotional arousal state which the observer would find unpleasant; may determine our actions
Cognitive area: emphasis on cost-reward calculation as determining how witnesses to emergencies act to remove their arousal; actions clearly influenced by mental calculation that implies a cognitive component to their model
Piliavin et al.: Key Theme
Likelihood of being helped in an emergency does not have to be reduced by there being many witnesses present, although this may be affected by bystanders being able to see how other witnesses are behaviour
Also suggests people are more likely to be helped if they seem to need help due to factors beyond their control (cane as opposed to being drunk)
First helpers likely to be male
