Document Summary
Latane and darley: sought to understand the social mechanisms behind the murder that occured in queens, new york in the 1960s. There were a reported 38 witnesses of the tragedy, yet no one called the police or intervened in the situation. Put students in various room where they were told to speak about their problems. During the study, the person from the other side of the speaker started to have a seizure. Only 31% of people got up to seek help, while the other 69% remained in the cubicle. When they decreased the number of students in the group, a larger percentage of them sought help. We know that the number of bystanders product different effects due to internal validity---an instance where only the independent variable is causes the dependant variable to change. But did it satisfy the issue of external validity? (the extent to which the results in an experiment can be generalized to real situations and people)
