  • Piliavin et al
    • The aim of the study was to investigate factors affecting helping behavior
    • The sample was 4450 people travelling on the New York Underground from 59th-125th street between 11am-3pm
    • Average number of passengers per carriage was 43 & average number of passengers in the critical ares was 8.5
    • Procedure: a team of 2 male and 2 female confederates entered the train from different doors. Both female confederates sat outside the critical area and recorded data during the journey, while the male 'model' and 'victim remained standing.
      • 70 seconds after leaving the station, the 'victim' would collapse and remain motionless until he received help.
        • the model would either wait 70 or 150 seconds to help if the victim hadn't received help. He would make the victim sit up and sit with him
          • the female confederates would try to elicit comments from the passengers. One would record the speed of help and the other the age, sex and gender of the helper
    • 4 victims (one from each team) were dressed identically in Eisenhower jackets, old slacks and no tie. they were all male aged 26-35. The cane victim walked with a cane, the drunk victim  smelled of alcohol and carried a bottle in a brown paper bag 3 victims were white, one black.
      • the male models were dressed casually but not identically, all aged 24-29
    • Model conditions
      • Critical early (critical area 70 seconds)
      • Critical Late (critical ares 150 seconds)
      • Adjacent early (adjacent area 70 seconds)
      • Adjacent Late ( adjacent area 150 seconds)
    • RESULTS:               62/65 cane trials the victim received spontaneous help                         19/38 drunk victim trials, the victim received spontaneous help
      • 90% of helpers were male
      • slight tendency for same race helping in the drunken condition
      • Diffusion of responsibility not evident, it was observed that the quickest help came from larger groups of people
