Prosocial and Antisocial Behaviour

This topic investigates the factors that lead people to help others (prosocial behaviour) or to act in ways that are harmful or indifferent (antisocial behaviour). Students explore the 'bystander effect' and the famous case of Kitty Genovese, alongside modern Australian examples. They look at the biological, psychological, and social factors that influence our decision to intervene in an emergency, such as the 'diffusion of responsibility'.

Role Play: The Bystander Dilemma

Students are given various 'emergency' scenarios (e.g., someone falling in a busy mall). They role-play the scene with different numbers of bystanders to see how the 'diffusion of responsibility' affects the speed of help.

Think-Pair-Share: Why Do We Help?

A few notes on teaching this unit


Watch Out for These Misconceptions

  • People don't help because they are 'cold' or 'uncaring'.

    Students often blame personality. Teachers should use the 'bystander effect' research to show that even very kind people are less likely to help if they are in a large crowd, due to situational pressures like 'audience inhibition'.

  • Altruism is always 100% selfless.

    Psychologists debate if 'pure' altruism exists. Using a structured debate on the 'social exchange theory' helps students explore the idea that we often help because the benefits (like feeling good) outweigh the costs.
