Melbourne: A study has revealed that consuming a little sugar or using the non-dominant hand could reduce outbursts and control people's impulse to fight when they get aggressive.
Studies presented at the University of New South Wales found that the unusual treatments worked by improving the self-control of aggressive people.
Psychologist Tom Denson, the study leader and an associate professor at the university, said that self-control is like a muscle, so it requires an energy source - that's the sugar - and practice; "that's why we ask people to use their non-dominant hand".
After the treatments, the aggressive participants felt less desire to act aggressively to others when provoked with an insult or taunt.
Dr Denson said while more research was needed, the therapies could form the basis of interventions for incarcerated violent offenders.
