Biological Approach Flashcards
The central nervous system, especially the brain is essential for what?
thought and behaviour.
what is human behaviour strongly influenced by?
Genetic inheritance
chemical processes in the brain are responsible for?
psychological functioning, can affect the bipolar mood disorder
are the brain and mind the same?
Yes
What do philosophers and psychologists argue that the difference between the brain and mind is?
The brain is physical & the mind is mental.
what do humans have much in common with?
animals
what sort of method is the biological approach?
scientific & technological
The function of different structures in the brain are investigated using?
EEG & MRI scanners
what do they use to investigate brain function?
Animals
What are the case studies about?
people who have had brain damage to understand the role of a specific area of the brain for personality, behaviour and perception.
Selective breeding of animals determines what?
what the behaviours and characteristics may have a genetic basis
why do these use experimentations with chemicals to effect the brain?
to investigate human behaviour
what is the study of identical and non identical twins about?
genetic inheritance or human characteristics.
what is genetics?
make up of organisms, how genes influence physical and behavioural characteristics.
What is heredity?
the traits, characteristics and behavioural tendencies inherited from their parents
what is a genotype?
a personals actual genetic make up represented in the normal 23 pairs of chromosomes.
What is a phenotype?
the actual expression of the persons genetic make up: physical appearance, behavioural and psychological characteristics.
What is the difference between genotype and phenotype?
The visibility of them.
What is a dominant gene?
when either both gene pairs are dominant or one is dominant and one is recessive
What is a recessive gene?
Does not influence the expression of a physical characteristic
What is the disease PKU?
Where genotype can be influenced by environmental factors and thus influenced the phenotype. The recessive gene can produce sever learning difficulties: unable to metabolise.
(A01) -In twin studies what does monozygotic (MZ) mean?
exactly the same - share the same genetic make up.
(A01) -In twin studies what does Dizygotic (DZ) mean?
aka fraternal twins. Not alike.
(A01)- in twin studies what does it mean when they are concordant?
if both or neither of the twins exhibits the trait.
