biological approach Flashcards
how do we understand human behaviour
we need to look at the biological structures and processes within the body. the mind lives in the brain so all thoughts, feelings and behaviour has a physical basis
how does genetics affect psychological characteristics
psychological characteristics such as intelligence is inherited similarly to our height and eye colour.
what research has been conducted in genetics
it has used monozygotic twins who share 100% dna compared to dizygotic who share 50%. recent research has found MZ twins have an increased concordance rate of developing schizophrenia compared to DZ
how does neural - neurochemistry play its role
chemicals can determine behaviour. at the synapse signals are sent between neurones by chemicals called neurotransmitters
how can imbalances in neurotransmitters affect behaviour
imbalances in the number of neurotransmitters are associated with atypical behaviour. for example low levels of serotonin is associated with depression and OCD
role of neural - brain structure
structure of organs such as the brain, central nervous system and peripheral nervous system can determine our behaviou
brain structure and functions
different lobes of the brain are linked with general functions such as the occipital love being associated with visual perception
what is evolution and behaviour
genes allow evolution to take place. natural selection by darwin ensures characteristics providing an evolutionary advantage pass from one generation to the next so useless genes die out
what are the scouts used
supporting evidence, opposing theory, usefulness (pete)
usefulness pete
p-useful due to having real world application - drug therapies
e-drug therapies developed for many mental illnesses based on research into neurotransmitters. Medications like antidepressants have been developed, helping people manage mental illnesses. it forms an explanation of why mental illnesses occur and helps people live a normal life
e-drugs like antidepressants may be successful for some patients but not for everyone. challenges value of the b.approach and suggests brain chemistry alone doesnt account for all cases of mental illness such as depression
pet supporting evidence
p - supporting evidence into how brain structure affects behaviour through phineas gage
e - what happened to him etc ratiu et al’s research
t - supports the approach’s theories of how behaviour is linked to the structure of our brain, shows how damage to the structure of the brain changed behaviour
pet - opposing theory
p-cognitive approach
e-believies behaviour is a result of thoughts and cognitive processes such as schema, it explains the process of how humans understand and react to information unlike b.approach
t-its better as biological approach’s research causes causation fallacy
