  • 1) If an ill person would get more help than a drunk person
  • 2) If people would help someone of their own race more than some
  • 3) If the intervention of a model would influence others helping behaviour
  • 4) If size of group is influences helping behaviour
  • Field Experiment
    • Experiment conducted in a natural environment

  • 2) Race of victim

  • Model wearing the same thing
  • Time of day
  • Train route kept the same (59th > 125th)
  • Where they fell > Critical Area
  • Where the observers sat > Adjacent area
  • Four people in each group
  • Sampling Method
    • Opportunity Sampling
    • Observed people on the train at the train
  • Fairly Diverse - Even mixture of Black and White people
    • Strengths of the sample

      • Same train journey for 3 months.

              • If passengers see the experiment twice they may see demand characteristics
        • If passengers see the experiment twice they may see demand characteristics
  • Strengths of obtaining the sample this way
    • Quick and easy
      • Wider range of people
        • Less likely to see demand characteristics
  • Weaknesses of obtaining the sample this way
    • Breaking ethical guidelines
      • Didnt get their consent
