Piliavin Flashcards
Aim
To investigate bystander behaviour in a natural setting.
To investigate the effect of the following variables on helping:
* type of victim
* race of the victim
* model behaviour
* size of bystander group.
Research method, design
Field experiment, independent groups design
IV
- type of victim - either drunk or ill
- race of victim - either black or white
- the model behaviour - close or distant proximity and helping early or late.
- size of bystander group (naturally occurring)
DV
- time taken for a passenger to help.
- total number of passengers who offered help.
- verbal remarks were also recorded.
Sample
opportunity sample, passengers travelling by subway between Harlem and Bronx on weekdays between 11:00 AM and 3:00 PM. The number of passengers was estimated to be 4450 people with 45% being black and 55% being white. There were around 43 passengers per carriage and 8.5 in the critical area.
Procedure
4 teams of student researchers from the University of Columbia carried out the study. On each trial, 2 males and 2 females boarded the train through different doors. Females were observers. The male confederates took the role of the victim and the model.
Observer
Both females were confederates who observed and recorded data. Females sat in the area adjacent to the immediate critical area.
Victim
he victim was played by four different men — 1 black and 3 white people. They were aged 26 - 35 years. They dressed in identical casual clothing — an Eisenhower jacket, old trousers, and no tie. On 38 of 103 trials, the victim smelled of alcohol and carried a bottle of alcohol wrapped in a brown bag. On the other 65 trials, they appeared sober and carried a black cane.
Model
They were white males aged 24 – 29 and were dressed informally. They raised the victim to the sitting position and stayed with him till the next stop.
Scene
Females observed passengers and recorded the race, gender, and location of each helper. The victim stood at the pole at the centre of the critical area. The model remained standing throughout the trial. Each trial used the same route as it included a 7.5-minute gap between 2 stations. At approximately 70 seconds, the victim staggered forward and collapsed. He laid on the floor looking upwards. If he received no help, the model would help him at the next stop. When ‘modelling’ helping, the model helped the victim to a sitting position and stayed with him until the next stop.
Trials
- Critical/early: the model stood in the critical area and waited 70 seconds to help the victim.
- Critical/late: the model stood in the critical area and waited 150 seconds to help the victim.
- Adjacent/early: the model stood in the adjacent area and waited 70 seconds to help the victim.
- Adjacent/late: the model stood in the adjacent area and waited 150 seconds to help the victim.
- No model condition: the model did not help the victim until after the trial was over and the train reached the next stop.
Results
- The frequency of helping was much higher than previously reported in laboratory studies. The majority of helpers were males.
- 80% of victims received spontaneous help. 60% of victims received help from more than one person. Participants are more likely to help victims with a cane (62/65 trials) than the drunk victim (19/38 trials). spontaneous helping was earlier for cane victims.
- Both black and white cane victims received equal help. In drunk conditions, same-race helping behaviour was found. Black drunk victims received less help overall.
- Early model intervention at 70 seconds slightly received more helping behaviour than waiting till 150 seconds.
- The research does not support the diffusion of responsibility. In fact, 7 person groups responded faster than 3 person groups.
- In 20% of trials, people moved away from the critical area during the incident. A high number of comments during the trials where help wasn’t given was recorded. More comments were recorded during drunk victim trials.
Conclusion
- In a natural setting, many people would offer spontaneous help to a stranger, even in a group situation.
- No diffusion of responsibility was found.
- Factors that may determine the decision to help:
- Type of victim (people with canes are more likely to be helped rather than a drunk victim)
- Gender of helper (men are more likely to offer help)
- Similar race (more help is given to a similar race, especially for drunk victims)
- The longer the emergency continues, the less likely it is for someone to help. They would cope with arousal in other ways.
Strengths
- High ecological validity
- High reliability
Weakness
- Ethics
- Low generalisability
