BIOLOGICAL MODEL( WJEC)
- ASSUMPTIONS
- Evolutionary approach
- adaptive
- EXAMPLE: altruism
- E.E.A
- Neurotransmitters
- nerve cells i.e neurons
- presynaptic vesicle
- post synaptic
- synaptic cleft
- examples:
- serotonin and depression
- dopamine and schizo
- localisation of
the brain
- outer cortex= cerebral
cortex for higher
cognitive functions
- split into 4 lobes
- frontal lobe
e.g.personality,problem
solving
- temporal lobe =
hearing
- occipital lobe = vision and colour
- parietal lobe = pain and touch
- DRUG THERAPY
- ANTI ANXIETY
- Stress, phobias
- reduce adrenaline and noradremanline
- BETA BLOCKERS reduce the above
- Benzodiazepines e.g. increase GABA which reduces anxiety.
- ANTIDEPRESSANTS
- depression
- SSRIS e.g. prozac
- increase reuptake of serotonin
- ANTIPSYCHOTICS
- psychotic disorders e.g schizo
- decrease dopamine in the brain to reduce hallucinations
- newer
atypical drugs
e.g. chlozaril
- KEY STUDY = RAINE
- METHOD
- 41(39/2) Age 34
- quasi experiment
- matched design
- age/ gender
- PROCEDURE
- opportunity sample
- PET SCAN compare NGRI/control
- injected with glucose tracer FDG
- given CPT task before test
- 10 corticol peels after 32 mins took
- FINDINGS
- 1. Reduced in corpus
collosum, prefrontal cortex
and LH with HAT
- 2. Increased in
cerebellum/occipital lobe and RH
with HAT( not previously linked to
violence)
- 3. no difference3. no difference bn NGRI and
control e.g. putamen and midbrain, not
previouslylinked
- CONCLUSION
- RELATIONSHIPS
- Assumption : neurotransmitters
- chemical messengers controlling behaviour and emotions
- neurons- presynaptic vesicle inhibit or stimulate receptor neuron
- example : oxytocin - hug hormone released during contact e.g.romantic relationships
- Evolutionary approach
- adaptive function
- e.g mother and child e.g. altruism
- EVALUATION
- SCIENTIFIC APPROACH
- Measured, tracked, objective e.g.
- PET scans in Raine study
- e.g. drug therapy
- DETERMINISITC
- predetermines behaviour so can be controlled
- e,g schizophrenia- dopamine
- SUCCESSFUL APPLICATIONS
- phamaceutical applications e.g. drug therapy
- Cherek and SSR
- drug therapy 60% improve with taking lithium ( Viguera et al)
- REDUCTIONIST
- NATURE RATHER THAN NURTURE
- INDIVIDUAL DIFFERENCES
