Transcript of Bystander Intervention Motivation

Bystander Intervention Motivation
History
In 1964, Kitty Genvese was murdered outside her apartment building while 38 people watched the event but failed to intervene.
Situational Model of Bystander Intervention
1. Diffusion of Responsibility
2. Pluralistic Ignorance
3. Evaluation Apprehension
Positive Bystander Effect
In dangerous situations or when more than one helper is needed the bystander effect is reversed and helping behaviour is actually increased in the presence of other bystanders
Expectancy Theory
Behaviour is influenced by the expected outcome. People are less likely to intervene when they expect:
John Darley and Bibb Latané investigated
this event and found that when people
are in the presence of others, the chance
of them helping decreases.
Bystander Effect
People are less likely to help in a situation when other bystanders are present
(Darley and Latané, 1968)
(Fischer et al., 2011)
(Rendsvig, 2014).
(Darley and Latané, 1968)
(Kohm, 2015)
their actions to be unhelpful/unnecessary
others to intervene/react
that they will be negatively evaluated by others
Social Cognitive Theory:
Self-Efficacy
Low self-efficacy prevents people from intervening because people do not believe they have the skills required to do so.
(Thornberg et al., 2012)
The Power of One
(Fischer & Greitemeyer, 2013)
One person is all it takes to create a social change.
When one person decides to intervene, others will follow.
(Fischer et al., 2011)
