what is the treatment-aetiology fallacy?
It’s the false belief that since a treatment works, it was a lack of whatever the treatment was that caused the disorder
What are 3 strength of using brain scans to study schizophrenia?
Why is it a weakness that many schizophrenic patients in brain scan studies take antipsychotic medication?
Because antipsychotics may themselves cause structural brain changes, making it unclear whether the abnormalities are due to the illness or the treatment
Why is cause and effect unclear in structural brain abnormalities and schizophrenia?
It’s unknown whether brain abnormalities cause schizophrenia or are an effect of having the disorder or its treatment
Why can the presence of structural abnormalities be a weakness in diagnosis?
These abnormalities are not exclusive to schizophrenia—they are also found in bipolar and schizoaffective disorders
> making diagnosis less specific
are bio theories determinist or free will
Highly deterministic, no room for free will:
are bio theories idiographic or nomothetic
highly nomothetic:
- Sees a person as a list of symptoms
are bio theories scientific
Yes- Lots of evidence that schizophrenia is biological, particularly as it runs in families
Also responds well to biological treatments
> But be cautious of the treatment-aetiology fallacy
One day we might be able to use brain scans to diagnose
> Brain scans are also highly scientific
are bio theories hollistic or reductionist
Reductionist:
- Ignores social and cultural factors
