Unit 3 - LAA2 - Approaches to Health (Bio, SLT, Behaviourism, Cognitive) Flashcards
What two things does the biological approach suggest causes ill health?
Genes and neurotransmitters
What are genes?
Biological information inherited from parents
What is meant by a genetic predisposition?
Having a risk to a behaviour due to an inherited gene
What are neurotransmitters?
Chemicals in the brain that send communications from one neuron to another
Chemicals in the brain that send communications from one neuron to another are known as…
Neurotransmitters
What 3 neurotransmitters are commonly found to be associated with mental disorders?
Serotonin
Dopamine
Noradrenaline
What is the role of serotonin?
Maintaining mood balance
What is the role of dopamine?
- Control brains reward and pleasure centres
- Regulate movements and emotional responses
When is noradrenaline produced?
In response to stress
Which neurotransmitter maintains mood balance?
Serotonin
Which neurotransmitter controls the brains reward pathways?
Dopamine
Which neurotransmitter is produced in response to stress?
Noradrenaline
What are two symptoms of depression?
Lowered mood
Disrupted activity levels
How do low levels of serotonin cause depression?
Leads to failure to regulate dopamine and noradrenaline
What does more recent evidence suggest about the cause of low levels of serotonin?
The presynaptic neuron reuptakes the neurotransmitter before it has time to reach the post synaptic neuron
How does an SSRI work?
Blocking the holes in the presynaptic neuron to prevent reuptake
What are the two types of learning suggested by the Behaviourist Approach?
Classical conditioning
Operant conditioning
