Darley and latane (1968) found that in potential emergency situations the more people that were present at a scene, the less likely it was that people would step in to . they found that the presence of other people affected the way people perceived the situation. this research would be conducted under which modern day perspective?

The correct answer is the bystander effect/ diffusion of responsibility. 

The bystander effect refers to the phenomenon where people are less likely to intervene and help victims in a crisis situation when a large people are present at a scene. The bystander effect occurs due to diffusion of responsibility, where people see themselves as less responsible for helping victims when other people are also present as witnesses to an incident.
