However, self-report measurements were used, which are indispensable and so may not be valid. Raleigh et al. (1991) also supports the serotonin has an effect on behaviour. There conducted a require on vervet monkeys, they! found that the monkeys fed on data-based diets high in tryptophan, which increases serotonin levels, exhibited decreased levels of aggression. And monkeys fed on diets that were low in tryptophan exhibited increased aggressive behaviour. This audition has low bionomic validity as it was conducted in a lab below artificial conditions. It is also arguable that as the experiment was conducted on animals it is hard to compare to humans.
