  1. Origins of Bullying

  2. Eley et al. (1999) Is antisocial behaviour genetic? • 1500 pairs of British and Swedish twins were studied. • Findings: Identical (MZ) twins showed a higher correlation of aggressive antisocial behaviour than fraternal (DZ) twins.

  3. Leiu & Raine (2004) Does malnutrition lead to violence? • A 14 year study of 1000 children living on the island of Mauritius. • At age 3, researchers selected children suffering from malnutrition. A control group who did not suffer from malnutrition were also studied. • At age 8, 11, and 17 researchers investigated how the children were behaving in school and at home based on either teacher or parent evaluations.

  4. Findings: Children suffering from malnutrition showed an increase in aggressive behaviour (e.g. 51% increase in violent behaviour by the age of 17).

  5. Dodge (1980) How do bullies think? • Design: Aggressive and non-aggressive boys were given a hypothetical story to read. • Each boy imagined that a classmate spilled a lunch tray all over his back. • The boys were then asked about the classmate’s intentions and how they would respond if this really happened to them.

  6. Findings: The aggressive boys read hostile intent into the story 50% more frequently than the others and responded more aggressively. • Negative attributions led to negative attitudes.

  7. Eron (1987) Parenting and violence • Findings: Parents of bullies were found to be often authoritarian-using very strict and often physical methods of punishment.

  8. Totten (2003) Parenting and Girlfriend abuse • 30 abusive adolescent males from a large city in Canada were studied with semi-structured interviews. • Mean age of the boys was 15.6 years, 6 belonged to an ethnic minority , and the rest were white. • Many were gang members and most had dropped out of school early.

  9. Findings: the boys had all been exposed to violent behaviour in the family. The fathers all used violence to control family members or to defend their honor. • In some cases, the fathers had given them instructions on how to abuse women in particular situations.
