The Biological Approach - Evaluation Flashcards
(5 cards)
1
Q
Strength - uses scientific methods of investigation.
A
- Investigating genetic / biological basis of behaviour - approach uses range of precise / highly scientific methods.
- Scanning techniques (fMRI) / drug trials - accurately measures biological / neural processes in ways not open to bias.
- Biological approach based on reliable data.
2
Q
Biological approach has real-life application.
A
- Increased understanding of biochemical processes of brain lead to development of psychoactive drugs treating serious mental disorders like depression.
- Drugs not effective for all patients but revolutionised treatment for many.
- Strength as sufferers live normal lives.
3
Q
Casual conclusions about neurotransmitters difficult to establish.
A
- Role of neurotransmitters in mental illness comes form studies showing particular drug reducing symptoms of disorders assuming the neuro-chemical in the drug causes the disorder.
- Like assuming cause of headache is lack of paracetamol as it’s effective in relieving symptoms of headache.
- Limitation as biological approach claims to discover causes when only associations exist.
4
Q
Limitation - approach based on determinist view of behaviour.
A
- Sees human behaviour governed by internal, biological cause over which we have no control.
- Disagrees with legal system where offenders are responsible for actions - discovery of criminal gene may complicate principle.
- Research may have negative implications for wider society as criminals may be able to excuse their behaviour.
5
Q
Methodological problem is difficulty separating nature and nurture.
A
- Identical, non-identical twins and related family members have genetic similarities, so any similarity in behaviour must be genetic from a biological perspective.
- The fact family members are exposed to similar environmental conditions is a confounding variable.
- Problem for approach as findings could be interpreted as supporting nurture rather than nature.
