This reduces the validity and reliability of the findings. Raleigh et al also found that vervet monkeys that fed on diets high in tryptophane which increases levels f serotonin, exhibited low levels of aggression. Monkeys who fed on diets low in tryptophan exhibited an increase in aggressive behaviour. Although theses finding defend that of Mann et al, the use of monkeys makes it difficult to generalize to humans.

The link between dopamine and aggression is not as established as that of serotonin and aggression. Lavine found that an increase in dopamine via the use of amphetamines, absorb found to increase aggressive behaviour.
