Supporting research evidence

• How did Katrina Gospic et Al (2011) study amygdala activity and aggression?

  • used the Ultimatum Game, where rejecting an unfair offer is seen as aggressive behaviour

  • MRI scans showed heightened amygdala activity when participants rejected their offers
• What happened when participants were given a sedative drug?

  • reduced amygdala activity

  • fewer rejections, showing reduced aggression
• What does this study suggest?

  • there is a strong link between reactive aggression and increased amygdala activity
