     When an emergency situation occurs, observers are more likely to take action if there are few or no
other witnesses. This phenomenon is referred to as the bystander effect.
     The bystander effect is also called the Genovese effect, which is named after Catherine "Kitty"
Genovese, a young woman who was cruelly murdered on March 13, 1964. Early in the morning,
28-year-old Genovese was returning home from work. As she approached her apartment entrance, she
was attacked and stabbed (刺) by a man later identified as Winston Moseley. Despite Genovese's
repeated cries for help, none of the dozen or so people in the nearby apartment building who heard her
cries called police for help. The attack first began at 3:20, but it was not until 3:50 that someone first
contacted police.
     Many psychologists were set thinking by the incident, as well as most Americans. As the conclusion,
the bystander effect came out and later proved by a series of studies and experiments.
     There are two major factors that contribute to the bystander effect. First, the presence of other people creates a division of responsibility. Because there are other observers, individuals do not feel as much
pressure to take action, since the responsibility to take action is thought to be shared among all of those
present. The second reason is the need to behave in correct and socially acceptable ways. When other
observers fail to react, individuals often take this as a signal that a response is not needed or not
appropriate.
     Other researchers have found that onlookers are less likely to take action if the situation is ambiguous
(not clear). In the case of Kitty Genovese, many of the 38 witnesses reported that they believed that they were witnessing a "lovers' quarrel", and did not realize that the young woman was actually being murdered.
