    • Arousal cost reward model- We either choose to help or ignore the situation by deciding what the cost to ourselves is and reward of helping if we do
    • Diffusion of repsonsibilty- the more bystanders, the less likely for helping behaviour to occur. If it happen only individually we would feel personally involved but when others are present the responsibilty is diluted
      • Arousal cost reward model- We either choose to help or ignore the situation by deciding what the cost to ourselves is and reward of helping if we do
    • Aim: To investigate , under real conditions, helping behaviour in bystanders of an unambiguous emergency situation.
    • Sample: unsolicted opportunity of prox 4450 subway passengers
    • Method: feild experiment using participants observation
    • Design: assumed independent measures design because we cannot assume whether a participants has witnessed the event more than once
    • Independent variables: Victim- drunk/ill Victim- black/white Model-early-critical- late adjacent. Late-critical. Late-adjacent
    • Dependant Variables- Speed of help. Frequency of Help. Race of Helper. Sex of helper. Movement from critical area. Verbal comments
    • Procedure:Fpur teams of researchers made up of business studies students from Columbia uinversity. Each group consisted of two females who were the observers and two male who took the role of model and victim. They boarded a train by different doors and varied on the carriage on each trial. There was a total of 103 trials; 38 for the drunk condition and 65 for the ill condition. The journey between two stations was uninterrupted for 7 and half minutes. The victim waited 70 seconds before standing and collapsing. He then waited for help from a bystander or the model. The early model stepped in after the frist 70 seconds and the late model waited 150 seconds before helping. The victims were always indentically dressed. The ill victim used a cane and the drunk victim smelt of alcohol
    • Results: 95% of spontaneous help across all trials. No model was required. 95% response for ill victim. 50% spontaneous help for drunk victim. 90% were male. Same race helping for black/drunk victim
    • Conclusion:there were no diffusion of responsibilty found in the study. There is evdeince that supports the idea of an arousal cost- model
