Supporting evidence

• multiple studies show that increased amygdala activity is linked to aggression
• Gospic et al


  Used the ultimatum game to measure aggression.

  The pp underwent fMRI brain scans,those who rejected unfair offers were considered aggressive.

  They found heightened and quicker amygdala activity in those who rejected unfair offers.

  Those given a sedative drug before the game,it reduced amygdala activity and aggression(half the amount of rejections).
