psychology being investigated
- bystander apathy
- diffusion of responsibility
bystander apathy
The presence of other people discourages a person from helping in an emergency. People are more likely to help when they are alone
diffusion of responsibility
Responsibility to help is shared between the number of bystanders present; the
more bystanders, the less responsible each person feels and the less guilty felt for
not helping.
background
-Interest in bystander apathy increased after the murder of Kitty Genovese
- A newspaper claimed that none of the 38 witnesses telephoned the police.
- Psychologists began to conduct lab experiments into ‘bystander behaviour’.
-The findings showed that, as group size increased, the amount of helping decreased. This was termed diffusion of responsibility.
aim
To investigate how the following factors affect helping behaviour in a real-life setting:
- type of victim (drunk or ill)
- race of the victim (black or white)
- modelled help
- group size
research methods
field experiment
research design
independent measures design
(participants experienced either an ill/black, an ill/white, a drunk/black or a drunk/ white trial).
data collection techniques
Covert observation
Observer 1 recorded:
– sex, race and location of passengers (seated or standing) in the critical area
– total no of pplin the car
– total no of ppl who went to help (including race, sex and location).
Observer 2 recorded:
- sex, race and location of passengers in the adjacent area
-time taken for the first passenger to help (the latency)
-Both observers recorded comments by passengers.
- Movement of passengers out of the critical area was also recorded.
independent variables
- type of victim, 65 ill (carried a cane) or 38 drunk (smelt of alcohol, carried a liquor bottle).
- race of victim (black or white)
- modeled help (from confederate): time (70 or 150 seconds after collapse) and
proximity (confederate helper was in the critical or adjacent area) - group size (naturally occurring, e.g. number of passengers in the carriage
dependent variables
- frequency of helping
- speed of helping
- race of helper
-sex of helper. - movement of passengers in and out of critical and adjacent areas.
- comments made by passengers
sample
Size: 4,450 unaware passengers.
Demographic: men and women; passengers on the New York subway; approximately 45 % black and 55 % white.
Sampling technique: opportunity sample consisting of passengers travelling on the 8th Avenue subway between 11 a.m. and 3 p.m. on weekdays.
procedure
- 2 male confederates (victim and model) and 2 female observers got on the express subway train via separate doors.
- The observers took separate seats while the male victim stood in the critical area. The male model stood in the adjacent or critical area.
-70 seconds after leaving the station, the victim staggered forward and collapsed. He lay still and looked upwards until he was helped. - The model helped the victim to his feet. None of the passengers helped.
controls
- The 7.5 train journey was used for all trials.
- Victims wore the same clothes (old trousers, jacket and no tie) and fell after 70 seconds in the same place and in the same way.
- Each team member started the journey in the same place
ethical issues
- Informed consent: participants were not informed that an observation was occurring
- Debriefing: lack of debrief. passengers moving out of the carriage when the subway stopped
meant debriefing was impossible. - Protection from harm: Passengers may have left the carriage in a negative psychological state
- Deception: passengers were unaware of the use of confederates
results
- Type of victim: a person appearing ill received more help than a person appearing
drunk (62/65 of trials vs. 19/38 of trials). - Race of victim: there was a tendency for same-race helping in the drunk condition.
- Modelled help: early models were more likely to prompt additional help than late
models. - Group size: there was an insignificant correlation between group size and helping,
- Males helped more than females: 90% of 1st helpers were male.
- People left the critical area in 20% of trials.
- Female comments included: ‘It’s for men to help him’, ‘I wish I could help him – I’m not strong enough.’
