a01 biological approache to psychopathology Flashcards
What are the 4 models of abnormality
The biological approach
Psychodynamic approach
Behavioural approach
Cognitive approach
What is its representing of mental disorders
As disease states equivalent to physical illnesses also makes it one of the most controversial
What are the 4 sections of outline of approach
Abnormality is caused by physical factors
Genetic inheritance
Certain genes lead to abnormal biochemistry an/or abnormal neuroanatomy
Viral infection
Talk about first intro section
Changes or illnesses may be caused by one of four possible factor
Genes
Biochemistry
Neuroanatomy
Viral infection
Talk about Genetic inheritance
The effects of genes om abnormality were demonstrated through High concordance rates for mental disorders in identical twins
Talk about another random factor
Claims that traits are inherited because at one time they may have been adaptive
Talk about certain genes lead to abnormal biochemistry and or abnormal neuroanatomy
Genes have been found to determine levels of hormones and neurotransmitters
Neurotransmitters have been associated with mental disorder (biochemistry)
Genes also determine the structure of the brain (neuroanatomy)
Who studied about viral infection
Torrey
What did Torrey do and find
Viral infection in thw womb linked with dev of abnormality
Link between influenza and schizo
What are the 2 sections fo rate methods of investigating the biological approach
Experiments
Correlational studies
Tall about experiments
They can be used to test effect of drugs and therefore support causal role of neurotransmitters
Talk about Correlation
Twin or family studies to produce concordance rates.
But doesn’t prove causation
