AP PSYCHOLOGY

Detailed explanation-1: -The bystander effect, or bystander apathy, is a social psychological theory that states that individuals are less likely to offer help to a victim in presence of other people.

Detailed explanation-2: -For example, when other people act calmly in the presence of a potential emergency because they are unsure of what the event means, bystanders may not interpret the situation as an emergency and thus act as if nothing is wrong.

Detailed explanation-3: -Altruism refers to prosocial behaviors that are carried out without expectation of obtaining external reward (concrete reward or social reward) or internal reward (self-reward). An example of altruism would be anonymously donating to charity.

Detailed explanation-4: -The bystander effect occurs when the presence of others discourages an individual from intervening in an emergency situation, against a bully, or during an assault or other crime. The greater the number of bystanders, the less likely it is for any one of them to provide help to a person in distress.
