Cards in this deck (7)
- 1Mann et al (1990)Gave 35 healthy subjects to dexfenfluramiune, which is known to deplete serotonin. Using a questionnaire to assess hostility and aggression levels, they found that dexfenfluramine treatment in males (but not females) was associated with an increase in aggression.
- 2Dabbs et al (1987)Measured salivary testosterone in violent and non-violent criminals. Those with the highest testosterone levels had a history of primarily violent crimes, whereas those with the lowest levels had committed only non-violent crimes.

5) The passivity of bystanders. - 6Hodgkinson et al (1985)Found that trainee nurses are more likely to suffer violent assault than experienced nurses.
- 7Raleigh et al (1991)Added support for the importance of serotonin in aggressive behaviour in a study on monkeys. They found that individuals fed on experimental diets high in tryptophan (which increases serotonin levels) exhibited decreased levels of aggression. Individuals fed on diets that were low in tryptophan exhibited increased aggressive behaviour. Suggesting that the difference in aggressive behaviour could be attributed to their serotonin levels.
