Q

Why does studying twins increase reliability of research into genetics

A

MZ twins - 100% similar, DZ only 50% (genetically), so if MZ is higher concordance rate, can suggest its due to genetics

Q

What was Raine et al’s study into neuroanatomy

A

PET scans to identify several areas of the brain in murderers which differed to matched controls -
Reduced activity in prefrontal cortex, amygdala and hippocampus
Abnormal asymmetries, reduced activity on left hemisphere and greater on right

Q

What is an example of brain plasticity

A

Maguire et al - studied brains of London taxi drivers through MRI - found more grey matter in posterior hippocampus than control group. Area associated to spatial and navigational skills

Q

What are neurotransmitters

A

Chemical messengers released by pre - synaptic neuron to post synaptic neuron when they connect at a synapse. If correct receptors, NT dock via lock and key

23
Q

What is the effect of GABA on behaviour

A

Body’s primary inhibitory messenger. Regulates anxiety, vision and motor control.
Lack of GABA - poor impulse control, brain seizures, bipolar/mania
Excess GABA - hypersomnia, lack of energy

24
Q

What are the effects of adrenaline on behaviour

A

Boosts oxygen and glucose to respond to stressor quickly. Increases HR and blood pressure

25
What are the effects of serotonin on behaviour
Control mood - regulate anxiety and happiness Lack of serotonin - depression, sadness, fatigue, suicidal thoughts, anxiety Excess serotonin - restlessness, hallucinations, confusion
26
What are positive evaluation points for the biological approach
Accessible ways to treat mental health problems Extremely scientific Research support - Maguire et al
27
What are negative evaluation points for the biological approach
Research on non human animals - validity, ethical issues Methodological issues - cause and effect
28
What does CIA stand for in the learning approach
Consequences (operant) Imitation (social learning) Association (classical)
29
What are the assumptions of the learning approach
All behaviour is learned and all we have at birth is the capacity to learn
30
Define a stimulus
Anything, internal or external, that brings about a response
31
Define a response
Any reaction in the presence of a stimulus
32
Define reinforcement
The process by which a response is strengthened
33
What is classical conditioning
Learning through association
34
What was Pavlov's involvement in classical conditioning
First to describe process by testing on animals - refers to conditioning of reflexes by associating new stimuli with innate body reflexes - dog, bell, food, salivation - little albert (watson and rayner)
35
Define extinction
If CS is continually presented without UCS the CR gradually dies out
36
Define spontaneous recovery
If a CR is not reinforced, it become extinguished, but may suddenly reappear
37
Define discrimination
The CR is only produced by presentation of the original stimulus, it doesn't extend to similar stimuli
38
Define generalisation
Extension of CR from original stimulus to similar stimuli
39
Define one trial learning
When conditioning occurs immediately
40
What is operant conditioning
Learning through consequences
41
What is Skinner's role in operant conditioning
Claimed all behaviour is learnt through environmental consequences - past and future. Tested this on rate with food and lever in a box
42
Define a primary reinforcer
Anything that fulfils a basic biological need e.g food fulfils hunger
43
Define a secondary reinforcer
Only becomes a reinforcer when associated with a primary reinforcer e.g caregiver gives food that fulfils hunger
44
What are the 2 methods to schedule reinforcement
Continuous and partial reinforcement
45
What is continuous reinforcement
Desired behaviour is reinforced every single time it occurs
46
What is partial reinforcement
Desired behaviour is reinforced only part or some of the time. Fixed ratio schedule - rat gets food every 5 presses. Variable ratio schedule - rat gets food after changeable number
47
What are the 3 types of reinforcement
Positive, negative, punishment
48
What is positive reinforcement
Increases the likelihood of a response occurring as use of reward to strengthen behaviour
49
What is negative reinforcement
Increases the likelihood of a response occurring because it involves the removal of, or escaping from unpleasant consequences to strengthen behaviour e.g crying stops when given milk
50
What is punishment
Decreasing the frequency of a desired behaviour by giving unpleasant consequences - Skinner, rat shocked when pressed lever so never pressed again
51
What are positive evaluation points for behaviourism
Credible evidence - little albert Extremely scientific - objective and falsifiable methods practical applications to society - phobias can be unlearned
52
What are negative evaluation points for behaviourism
Methodological issues - Pavlov studied dogs Environmental determinism - incomplete explanation
53
What is the Social Learning Theory
Learning through imitation
54
What is imitation
Copying behaviour observed in a role model, may or may not have gained reward
