Key Study: Piliavin (1969) – Field Experiment

In this video you might see some factors that influence bystanderism. But as these aren’t published studies, we can’t use these as evidence so following the video is a study that we can use as evidence.

What factors can you see influencing bystanderism the following field experiment by Piliavin’s?

Background Information

Much of Darley and Latane’s research into factors influencing bystanderism was conducted in the laboratory, so Piliavin et al wanted to see if similar results would be gathered in a real-life situation. Earlier research also focused on situational factors surrounding the would-be helpers, but what about the characteristics of the victim (i.e. the person in need)? Would you be more likely to help someone of your own race, or would it not matter? If you’re female, would be willing to help a male stranger, and vice-versa? Piliavin et al put some of these questions to the test in their field experiment in 1969.

The Study

Methodology

The research was conducted over a six week period in New York City in 1969. Four teams of researchers were assembled to gather data on a specific train line between Harlem and the Bronx between 11am – 3pm on weekdays. The typical demographic of race on this line at this time was 55% white and 45% black commuters. Over the six week period, the researchers conducted 103 trials.

The research teams consisted of four members:

  1. Victim (there were three white victims and one black, all dressed identically)
  2. Model (the person that would help after a designated period of time)
  3. Two observers (the researchers gathering the data)

A typical trial followed the same pattern: the research team would board a train carriage on the Harlem – Bronx line, two each at different doors. They would take the train between 59th – 125th street (and vice versa) which was a 7 ½ minute journey. 70 seconds into the journey the victim would collapse and lay on his back and stare at the ceiling, either waiting for someone to help or for the model to intervene. The model would wait either 70 seconds or 150 seconds (two different conditions) and if no-one had helped by that time they would help the victim into a seating position. If no-one else on the train had come to help the model by the time the train started to slow for the next stop they would help them to their feet and exit the train together. The researching team would then cross the platform and repeat the process going in the other direction (6 – 8 trials were run per day on average).

There were two different conditions for the victim besides their race:

Results

Drunk vs. Injured

Race (black and white)

Interestingly in the drunk condition victims were mainly helped by those of their own race.

Gender

Model

Number of bystanders
