VICTIMS

A

The four victims (one from each team) were males, aged between 26 and 35, three white and one black.

All were identically dressed in jackets, trousers and no tie.

Q

MODELS

A

The models (white males aged 24 to 29) were all dressed casually. There were 4 different model conditions used across both drunk and cane conditions.
Critical area early – helped 70 seconds after the collapse.
Critical area late – helped 150 seconds after the collapse.
Adjacent area early – helped after 70 seconds
Adjacent area late – helped after 150 seconds

Q

RESULTS

A

Diffusion of responsibility was not evident, in fact the quickest help came from the largest groups.

Helping behaviour was very high.

In the majority of trials, the victim was helped before the model acted.

Cane victim received spontaneous help on 62 out of 65 trials

Drunk victim received spontaneous help on 19 out of 38 trials

Q

Qualitative data

A

Female passengers said

“It’s for men to help him.”
“I wish I could help him – I’m not strong enough.”

Q

Describe how Piliavin’s study in bystander apathy links to the key theme of responses to people in need [4]

A

Who: approx. 4450 male and female adults travelling on a New York subway between 11am and 3pm weekdays during the months of April and June ‘68
What: To investigate different variables on helping behaviour
How: a drunk/cane male victim entered a subway carriage on a 7 ½ minute journey and collapsed after the first stop. The victim stood near a pole in the critical area. After about 70 seconds he staggered forward and collapsed. Until receiving help he remained supine on the floor looking at the ceiling. If he received no help by the time the train stopped the model helped him to his feet. At the stop the team disembarked and waited separately until other passengers had left the station. They then changed platforms to repeat the process in the opposite direction. The observers recorded the responses
Link: The cane victim received spontaneous help 95% of the time compared to 50% for the drunk victim, overall there was 100% help for the cane and 81% for the drunk victim and 90% of helpers were male. There was no diffusion of responsibility found. Therefore this links back to the key them of responses to people in need as it shows that people will help one another when in need (no evidence of diffusion of responsibility) but people are more likely to help when an individual is ill rather than drunk.

Q

Field experiment - strength

A

Field experiment
This means that it will have high ecological validity as it has taken place in a real life setting – Ps are behaving in their natural way.
The study took place on a subway in New York for a 7 ½ minute train journey
The field experiments were not subject to demand characteristics, as the travellers on the underground train did not know they were part of an experiment so their behaviour would have been a ntural

Q

Field experiment - weakness

A

Field experiment
There is low control over EV’s as this is taken place in a natural setting
Some of the passengers may have witnessed the collapsing on several occasions as therefore would have responded differently.

Q

Data - strength

A

Quantitative data was collected
This allowed the different victims to be easily compared
They found that 100% of cane victims received help and 81% of drunk victims

Q

Data - qualitative

A

Qualitative data was also collected
This allowed the observers to understand why people didn’t help
90% of the helpers were male. Females were heard to say that it’s for men to help him, or I wish I could help but I’m not strong enough

16
Q

ethics - weakness

A

There a number of ethical issues associated with Piliavin et al.’s study. Participants were unaware that they were taking part in an experiment, therefore they could not consent to take part and it was also not possible to withdraw from the study or be debriefed. Furthermore, seeing a victim collapse may have been stressful for the participants, they also may have felt guilty if they didn’t help, therefore leading to psychological harm.

17
Q

Reliabilty - strengnth

A

There were high levels of standardised procedures and controls
The study place over 3 months and 4450 people were tested over a number of trials
All the victims wore the same clothes, fell down at the same time, stood in the same area. The models also entered at the same time

18
Q

reliability - weakness

A

Because of methodological problems, there were more cane trials than drunk trials and more white victims than black victims. Therefore the results from each group’s trials cannot always be reliably compared with each other.

19
Q

sample - strength

A

The sample size was also very large and we would assume a fairly representative sample of New Yorkers
It included both males and females

Q

sample - weakness

A

However it was just p’s were rode the subway at that particular time
