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.


Origins of bullying

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

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.


Origins of bullying

  • 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.
