of dopamine

small studies, as most are of men in prisons

- SOCIALLY SENSITIVE- may
not want to admit they are
aggressive
- ANIMALS- not generalisable.
bio and cognitively different
- ANDROCENTRIC- testosterone,
mostly conducted on males
- SOCIALLY SENSITIVE- may
not want to admit they are
aggressive
- Cortisol
- A01
- High levels inhibit
testosterone and so
aggression. Low levels
correlate with violence
