Biological Approach Flashcards
Genetics
Monozygotic twins - identical
Dizygotic twins - not identical
Family studies are useful due to genetics being shared and similar
Nature/nurture debate - whether behaviour is influenced more by our genetic inheritance or environmental factors like upbringing
Define concordance rate
The likelihood of one twin having something and the other twin also having it
Genes
Genes are passed down through the family
Phenotype - the phenotype is the physical expression or characteristics of that trait
Genotype - set of genes in DNA which is responsible for a particular trait
Brain structure
Damage to parts of the brain can cause serious changes to a persons ability to function normally
Structural changes could be physical such as neglect or an accident or also occur due to poor mental health and psychological damage such as depression
Clearly show physical changes
Evaluation of the biological approach
Positives:
Use of Brain scans and other modern technology has identified many biological aspects of psychopathologies
Research into genetics has identified a genetic or inherited component in many things like phobias
Negatives:
Drug treatments are never effective for all people
The approach is reductionist which means that it believes that the biological factors are most important which takes the nature debate
