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

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
Q

What are the effects of serotonin on behaviour

A

Control mood - regulate anxiety and happiness
Lack of serotonin - depression, sadness, fatigue, suicidal thoughts, anxiety
Excess serotonin - restlessness, hallucinations, confusion

26
Q

What are positive evaluation points for the biological approach

A

Accessible ways to treat mental health problems
Extremely scientific
Research support - Maguire et al

27
Q

What are negative evaluation points for the biological approach

A

Research on non human animals - validity, ethical issues
Methodological issues - cause and effect

28
Q

What does CIA stand for in the learning approach

A

Consequences (operant)
Imitation (social learning)
Association (classical)

29
Q

What are the assumptions of the learning approach

A

All behaviour is learned and all we have at birth is the capacity to learn

30
Q

Define a stimulus

A

Anything, internal or external, that brings about a response

31
Q

Define a response

A

Any reaction in the presence of a stimulus

32
Q

Define reinforcement

A

The process by which a response is strengthened

33
Q

What is classical conditioning

A

Learning through association

34
Q

What was Pavlov’s involvement in classical conditioning

A

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
Q

Define extinction

A

If CS is continually presented without UCS the CR gradually dies out

36
Q

Define spontaneous recovery

A

If a CR is not reinforced, it become extinguished, but may suddenly reappear

37
Q

Define discrimination

A

The CR is only produced by presentation of the original stimulus, it doesn’t extend to similar stimuli

38
Q

Define generalisation

A

Extension of CR from original stimulus to similar stimuli

39
Q

Define one trial learning

A

When conditioning occurs immediately

40
Q

What is operant conditioning

A

Learning through consequences

41
Q

What is Skinner’s role in operant conditioning

A

Claimed all behaviour is learnt through environmental consequences - past and future. Tested this on rate with food and lever in a box

42
Q

Define a primary reinforcer

A

Anything that fulfils a basic biological need e.g food fulfils hunger

43
Q

Define a secondary reinforcer

A

Only becomes a reinforcer when associated with a primary reinforcer e.g caregiver gives food that fulfils hunger

44
Q

What are the 2 methods to schedule reinforcement

A

Continuous and partial reinforcement

45
Q

What is continuous reinforcement

A

Desired behaviour is reinforced every single time it occurs

46
Q

What is partial reinforcement

A

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
Q

What are the 3 types of reinforcement

A

Positive, negative, punishment

48
Q

What is positive reinforcement

A

Increases the likelihood of a response occurring as use of reward to strengthen behaviour

49
Q

What is negative reinforcement

A

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
Q

What is punishment

A

Decreasing the frequency of a desired behaviour by giving unpleasant consequences - Skinner, rat shocked when pressed lever so never pressed again

51
Q

What are positive evaluation points for behaviourism

A

Credible evidence - little albert
Extremely scientific - objective and falsifiable methods
practical applications to society - phobias can be unlearned

52
Q

What are negative evaluation points for behaviourism

A

Methodological issues - Pavlov studied dogs
Environmental determinism - incomplete explanation

53
Q

What is the Social Learning Theory

A

Learning through imitation

54
Q

What is imitation

A

Copying behaviour observed in a role model, may or may not have gained reward

55

A
