In the Piliavin procedure, how soon after the subway left the station did the victim begin their act?

In the Piliavin procedure, the victim began their act approximately 70 seconds after the subway departed from the station. This timing is crucial as it allowed for a significant observation period during which the responses of passengers could be recorded in a realistic setting. The choice of 70 seconds allowed the researchers to capture the dynamics of helping behavior in a more naturalistic environment, as it was sufficiently long for passengers to settle into their commute while still being within a timeframe where they would likely respond to a perceived emergency. This timing also provided insight into situational factors that influenced bystander behavior, such as the gradual formation of social relations among passengers that might affect whether they chose to intervene.
