- biological approach
- influence of genes
- to determine the involvement of genetic factors. we use twin studies to compare the concordance rate of the mz twins to the dz twins
- concordance rate- the % rate/chance of one twin having a particular characteristic (schizophrenia) if the other twin already has it
- influence of biological structures
- these play an important role in behaviour. the nervous system carries messages from one part of the body to another by using neurons
- influences of neurochemistry on behaviour
- neurotransmitters are electrochemical impulses that transmit messages from one neuron to the next by travelling through synapses
- there are different types of neurotransmitter, some which trigger an impulse (excitatory) and some of which stops an impulse from firing (inhibitory)
- dopamine is an excitatory neurotransmitter associated with drive and motivation
- serotonin is an inhibitory neurotransmitter associated with mood
- dopamine is an excitatory neurotransmitter associated with drive and motivation
- there are different types of neurotransmitter, some which trigger an impulse (excitatory) and some of which stops an impulse from firing (inhibitory)
- neurotransmitters are electrochemical impulses that transmit messages from one neuron to the next by travelling through synapses
- influence of evolution
- psychologists believe that some human traits are passed from generation to generation because, at some point, they give survival advantages to humans
- examples are- aggression, attachment, flight or fight response
