biological

• highly reductionist as it reduces complex behaviours down to our biology eg. depression is low levels of serotonin which ignores many other important factors like social
• drug therapy is the most commonly used approach

  • Cole found that 75% of people with sz showed much improvement when treated with antipsychotics compared to 25% given a placebo
• a weakness is the appraoch can be critisied for being highly deterministic eg. depression is due to low levels of serotonin as it suggests people have no control over their mental health
• it is highly scientific as behaviour ca be explained in measurable biological influences eg. neurotransmitters and uses scientific methods like lab experiements and brain scans - Raine

  therefore it is based on objective, measurable, controlled research so its respected and trusted
