Biological approaches Flashcards
What do biological psychologist think
Human behaviour depends on nature and nurture
What is the biological approach
The influence of genes, biological structure and neurochemistry on behaviours
What is genotype
the set of genes that a person possesses
What is phenotype
Physical characteristics that are determined by genes and environment
What are dizygotic twins
non identical twins
What are monozygotic twins
Identical twins
What are twin studies used for
To investigate if certain psychological characteristics have a genetic base
How do they come to a conclusion about how twin studies
Using concordance rates which determine to what extent they share characteristics
How does Darwin’s theory link to biological approach
His theory of natural selection links because it shows that any genetically determined behaviour that enhances an individuals survival will continue throughout generation
Pros of this approach
There is a real word application
Highly scientific methods are used to study biological and genetic basis of behaviour ( fMRI scans)
What benefit is it learning about neurochemistry
increases understanding of neurochemical process that are associated with the use of psychoactive drugs
What treatment has this approach promoted
Promoted treatment of clinical depression by using anti depressant drugs
How do antidepressant drugs work
Increase levels of the neurotransmitter serotonin at synapses in the brain
which reduces the D symptoms
Counter argument for this approaches
Antidepressant drugs don’t work for everyone
What study proved that anti depressant don’t work
Andre Cipriani et al in 2018
studied 21 anti depressant drugs
