| Question | Answer |
|---|---|
| Name 2 symptoms of schizophrenia | Delusions, Hallucinations, Disorganised Speech, Catatonic Behaviour |
| How many people are affected by schizophrenia | Affects roughly 1% of the population |
| What are the types of symptoms for schizophrenia | Positive, Negative, Cognitive |
| How does the dopamine hypothesis explain schizophrenia diagnosis | The hypothesis says that the brains of patients with schizophrenia produce more dopamine than those without schizophrenia. There is increased D2 receptor activity which links to positive symptoms like hallucinations and delusions. |
| One strength of the dopamine hypothesis | Supported by the fact that drugs given to schizophrenic patients work by blocking dopamine receptors. If the receptors are blocked less dopamine can be taken up. |
| One weakness of the dopamine hypothesis | Carlsson et al (2000) said that when undergoing scanning humans may feel under pressure and may respond differently to normal. This means that any findings, like those relating to brain activity linked to psychotic functioning, may lack validity. |
| In the genes explanation, what is the risk of developing schizophrenia if you have an identical twin with the disorder | 40-65% |
| One strength of the genes explanation | Heston (1966) compared children who had been adopted at birth as their natural mothers had schizophrenia with children with mentally healthy mothers. As adults, 10% of these children with mentally ill mothers developed disorder but none of the others did. |
