Biological Flashcards
Biological approach
Behaviour and experiences determined by the nervous system
Kayat
Physiological exp
Ontogenic exp
Evolutionary exp
Functional exp
Physiological exp
Structures + processes within controlling behaviour
Ontogenic exp
Development of behaviour down to external influences
Evolutionary exp
Gene inheritance - survival - EEA decided behaviour
Adaptive benefits passed down
Genetic
Role of inherited genes - malfunction = production of symptoms of disorders
Twin / family studies
Old way of measuring - test for CC
New = mapping specific genes + a focus on smaller units
Diathesis stress model
Some people may be biologically predisposed to a disorder but it may only develop through environmental triggers
Biological structures
Behaviours are shaped by physical structures of the brain
Damage = faults in brain’s pattern of development
Abnormality = damage / irregular structures
Neurochemistry
The signal passing between cells which inhibit / excite
Focus on chemical therapies
Genotype
Genetic makeup of an individual
Phenotype
Physical expression of a genotype
E.G blue eyes
Strengths of bio approach
- Scientific methodology (e.g brain scans)
- RL benefits (e.g drug therapies)
- Removal of patient blame
Weaknesses of bio approach
- Biologically reductionist
- Hard determinism
- Drug treatments = side effects
- Twin studies
- Cultural differences
