Biological Approach
Brain Structure
parietal
perception of stimuli + attention
occipital
visual processing
frontal lobe
reasoning, emotions + decision making
temporal
memory + speech
enlarged ventricles in central brain are and prefrontal cortex are linked to schizophrenia
Assumptions
everything psychological has a biological explanation
to study the mind we need to study the brain
need to study physiology and biochemistry to understand behaviour
Neurochemistry
serotonin
inhibitory transmitter - maintains a stable mood - reduces aggression - reduces offending behaviour
dopamine
excitatory transmitter - associated with motivation - impulse
Genes
Gs + Ps
Genotype
inherited genes
genetic code in the DNA
Phenotype
expressed traits
physical appearance as a result of genotype
Twin Studies
concordance rate
probability of things shared between twins
monozygotic twins
identical twins
share 100% of genes
dizygotic twins
non identical twins
share 50% of genes
example
gottesman + shields
schizophrenia
mz 48%
