Document Summary
The study of the causes of abnormal behaviour (look up better definition): medical-disease models. Genetic model: schizophrenia and depression have genetic component to these. If parents or grandparents have these, its highly likely that they could too. Stress can make it so genetic dispositions more likely to happen (eg schizophrenia, etc). Depression has a concordance rate of 80% even though its not clearly genetically. Biochemical model: drugs that are most effective in treating depression effect serotonin (they have too little of it). Schizophrenia is when they have too much dopeamine. Social determinants stressors. (significant stressors: death in the family, loosing job, divorce (loosing a significant relationship), starting a significant relationship). More stress you have, the more likely you are to be depressed. Environmental moulds who we are from what we learn from that environment. This model stresses the individual"s reaction to themselves and to the external world. Interested in exploring the person"s interaction with itself an what is around it.
