Prosocial behavior is another major research area in social psychology. Prosocial behaviors are those that involve helping and cooperating. Researchers often look at why people help others, as well as why they sometimes refuse to help or cooperate. This case captured national attention when reports revealed that neighbors had witnessed her attack and murder, but failed to call the police for help. Research inspired by the case produced a great deal of information on prosocial behavior and how and why people choose - or sometimes refuse - to help others.
