Q

What does the two-process model state?

A

Phobias are acquired (learned in the first place) by classical conditioning and then continue because of operant conditioning

Q

What is operant conditioning?

Q

How does acquisition by classical conditioning occur?

A

We learn to associate something of which we initially have no fear with something that already triggers a fear response

Q

How did Watson and Rayner study acquisition by classical conditioning?

A

They created a phobia in 9-month-old Little Albert who showed no unusual anxiety at the start of the study
They showed him a white rat while making a loud, frightening noise by banging an iron bar close to his ear

Q

What were the findings of Watson and Reyner’s study?

A

Little Albert became scared of the rat even though he wasn’t initially scared of it and wanted to play with it

17
Q

How does a neutral stimulus produce a fear response?

A

When the neutral stimulus and the unconditioned stimulus are encountered close together in time, the neutral stimulus becomes associated with the unconditioned stimulus and they both produce a fear response

18
Q

What does the neutral stimulus become once it causes a fear response?

A

Conditioned (learned) stimulus

19
Q

What does a conditioned stimulus produce?

A

Conditioned response

20
Q

How did Watson and Reyner generalise their findings?

A

They tested Albert by showing him similar objects, such as a non-white rabbit, a fur coat, and Watson wearing a Santa Claus beard made of cotton balls, to which Little Albert responded with distress

21
Q

Why did Mowrer propose the idea of maintenance by operant conditioning?

A

Responses acquired by classical conditioning tend to decline over time but phobias are often long-lasting

22
Q

When does operant conditioning occur?

A

When behaviour is reinforced (rewarded) or punished

23
Q

How does reinforcement affect behaviour?

A

It increases the frequency of a behaviour

24
Q

What are the two types of reinforcement?

A

Negative and positive

25
Q

What is the negative reinforcement in terms of phobias?

A

An individual avoids an unpleasant situation which produces a desirable consequence so the behaviour will be repeated

26
Q

How does Mowrer explain the negative reinforcement in phobias?

A

Whenever we avoid a phobic stimulus we successfully escape the fear and anxiety we would have suffered if we remained there

27
Q

How does negative reinforcement affect the phobia?

A

Reduction in fear reinforces the avoidance behaviour and so the phobia is maintained

28
Q

Why does the two-process model have good explanatory power?

A

It explains how phobias could be maintained over time, which has good implications for therapies because it explains why patients need to be exposed to the feared stimulus

29
Q

How is good explanatory power a strength?

A

It has a good real-life application to therapy

30
Q

What are the two limitations of the two-process model?

A

1) There is an alternative explanation for avoidance behaviour
2) It is an incomplete explanation of phobias

31
Q

What is the alternative explanation for avoidance behaviour?

A

Not all avoidance behaviour is the result of anxiety reduction - some avoidance behaviour appears to be motivated by positive feelings of safety

32
Q

Give an example of evidence to support the alternative explanation for avoidance behaviour?

A

Buck (2010) explained that some agoraphobic patients were able to leave their house with a trusted person with little anxiety but not alone - person was their safety factor

33
Q

Why is the alternative explanation for avoidance behaviour a problem for the two-process model?

A

The model only suggests that avoidance is motivated by anxiety reduction, which is clearly not true

34
Q

Why is the two-process model an incomplete explanation of phobias?

A

Bounton (2007) points out that evolutionary factors may have an important role but the model doesn’t mention this

35
Q

How do evolutionary factors affect phobias?

A

We easily acquire phobias of things that have been a source of danger in our evolutionary past, such as snakes and the dark

36
Q

How does Seligman (1971) call this effect?

A

Biological preparedness

37
Q

What is biological preparedness?

A

The innate predisposition to acquire certain fears

38
Q

How does biological preparedness apply to current phobias?

A

It is rare to develop phobias of more dangerous things such as cars and guns because they have only existed very recently so we’re not biologically prepared to learn fear responses towards them

39
Q

Why is the phenomenon of preparedness a serious problem for the two-process model?

A

It shows that there is more to acquiring phobias than simple conditioning

40
Q

Why does the two-process model not apply to all phobias?

A

Some phobias don’t follow a trauma so no conditioning could have taken place
