animals given amphetamines which cause excess dopamine and look to see if this reproduces the symptoms of schizophrenia in the animals. if it does, this supports dopamine hypothesis
3 of 8
how can genetic causes of schizophrenia be seen using this method?
use amphetamines to induce schizophrenia and then observe if this is transferred to their offspring

animals have shorter gestation periods which means that genetic causes can be studies more quickly than they could be with human participants
5 of 8
STRENGTH: can cause more harm
can cause more harm to animals and induce schizophrenia without breaking ethical guidelines whereas it would be unethical to give a human schizophrenia
6 of 8
WEAKNESS: generalisable
difficult to generalise findings from animals to humans
