Q

Outline the cognitive characterises of phobias?

A
  • irrational thoughts
  • Person knows there fear is excessive

Example - phobia of spiders is irrational as they are mostly harmless however you can not see beyond the immediate fear and think rationally

Q

Outline how phobias are learnt according to the two process model?

A

Acquired through association between a neutral stimulus (NS) and something that already triggers a natural fear response (UCR)

  • classical conditioning involved with formation
  • eg little Albert becoming conditioned so that he would cry when presented with furry white objects

Q

Outline how phobias are maintained according to the two process model?

A

Behaviour more likely to be repeated if the outcome is rewarding - the avoidance of the phobia stimulus reduces fear thus reinforcing (example of negative reinforcement)

Q

Give an example of how a phobia is learnt through association - focus on little Albert?

A

11 month old boy (little Albert) showed no fear to white furry objects, eg white rat (neutral stimulus) Watson and Rayner created a conditioned response by producing a loud sound when he reached out to the rat caused him to be started and cry

  • associated the white rat with fear of the loud noise and would cry when seeing it

Q

Give an example of how a phobia develops through classical conditioning - use them example of someone being bitten by a dog?

A

Being bitten (UCS) creates fear (UCR)
Dog (NS) associated with being bitten (UCS)
Dog (becomes CS) produces fear response (CR)

Q

Outline the social learning component of behaviourist explanation?

A
  • not part of two-process model
  • suggests phobias may be acquired through modelling behvaiour of others
  • eg seeing a parent respond to a spider with extreme fear may lead to child to acquire a similar behaviour because it appears rewarding (fearful person gets attention)

Q

Outline research to support social learning theory of phobias?

A

Mineka (1984) found that monkeys could develop snake phobias just by watching another monkey fear snakes - with the monkeys watching never having seen a snake

Q

Outline a weakness of using classical conditioning as an explanation of phobias?

A

Does not show that ‘real life’ phobias develop this way, as we could be biologically wired/prepared to associate things which are harmful to us with fear for our own survival

  • for example we could be evolutionary prepared to fear heights

Q

Outline how the two-process model is supported by evidence that classical conditions is involved in the development of phobias?

A
  • people with phobias often do recall a specific incident when their phobia appeared (eg being bitten by a dog)
  • sue et al suggests that different phobias are result of different processes - agoraphobics associated with specific incident where as arachnophobia’s can attribute it to modelling

Q

Outline why the behavioural explanation can be viewed as incomplete?

A

NS being associated with fear should result in phobia but its not always the case - not everyone that’s bitten by dogs develops a phobia of them

  • could be explained by diathesis-stress model, we inherit genetic vulnerability for developing disorder but it will only manifest if triggered by life event

Q

Explain why the two-process model is accused of ignoring cognitive factors?

A
  • cognitive aspects of phobias that are not explained by behaviourist framework are hard to treat with behavioural treatments - may be better treated with CBT (cognitive therapies)
  • cognitive approach proposes that phobias develop as the consequence of irrational thinking (eg being trapped in a lift and thinking your going to suffocate and die) could create extreme anxiety and trigger a phobia
17
Q

Explain how phobias developing could be explained by biological preparedness - why is this a weakness of behavioural approach?

A
  • Behavioural can not explain all phobias
  • Martin seligman argued that animals/humans are genetically programmed to rapidly learn association between potentially life-threatening stimuli and fear (‘ancient fears’, like height,strangers and snakes)
  • this increases your likelihood of survival so are passed on (evolutionary)
18
Q

Give behaviourist approaches for treating phobias?

A
  • systematic desensitisation (SD)
  • flooding
19
Q

Outline systematic desensitisation (SD)?

A
  • based on principals of classical conditioning
  • therapy aims to extinguish undesirable behaviour by replacing it with a more desirable one
  • there are stages to the therapy
20
Q

How many session of systematic desensitisation are required?

A

Number of sessions vary depending on the strength of the phobia - usually 4-6 sessions but can be up to 12

21
Q

Outline and explain stage 1 of systematic desensitisation?

A

Therapist trains client in deep relaxation techniques (eg practicing deep breathing using the diaphragm or muscle relaxation)

  • the aim is to replace fear response with relaxation
22
Q

Outline and explain stage 2 of systematic desensitisation?

A

Therapist asks client to create fear hierarchy, from the least feared situation to the highest level of fear associated with their phobia

Example:
Least fearful - thinking about a spider
Medium fearful - looking at a spider in a box
Most fearful - holding a spider with bare hands

23
Q

Outline and explain stage 3 of systematic desensitisation?

A
  • client starts to work way through hierarchy, performing their relaxation techniques they have previously learned
  • once they feel comfortable at each level, they move up to the next stage of the hierarchy, if at any stage the fear becomes to much they move down to the previous one until they feel in a relaxed state
24
Q

What is the goal of systematic desensitisation?

A

Client starts to associate their phobia with relaxation, eg looking at a spider where they are relaxed and calm

25
Q

Outline Gilroy’s research support for Systematic desensitisation?

A

Followed up on 42 patients who had been treated with SD their phobia was assessed including using spider questionnaire and by assessing their response to a spider - A control group was treated by relaxation without exposure

followed up 3 months after treatments the SD group was less fearful then the relaxation group

26
Q

Outline the behavioural technique of flooding for phobias?

A

more intense therapy that is immediate and uses unavoidable exposure to the feared object or situation - you naturally start to calm down as fight or flight starts to reduce

27
Q

Outline how flooding prevents avoidance behaviour during treatment?

A

Patient can not leave the situation until they are calm and anxiety has reduced - this allows the client to learn that the stimulus is harmless so they no longer produce the conditioned fear response

28
Q

Outline how flooding treatment can change areas of the brain?

A

Amygdala (area of brain that is the centre of brains emotional response) can be re-trained to stop overreacting

29
Q

How many session of flooding are usually required?

A

One long session

30
Q

Define extinction in regard to treating phobias?

A

involves learning to associate the thing you fear with something neutral - exposure to phobia but without gradual build up in an anxiety hierarchy way

Can be done in two ways - vitro or vivo

31
Q

Outline the two ways extinction can be done?

A

Vitro - the client imagines the exposure to the phobic stimulus

Vivo - the client is actually exposed to the phobic stimulus

32
Q

Outline research support for flooding?

A

Studied 24 Vietnam veterans with PTSD, soldiers received 14 to 16 sessions of flooding - they were tested before, after and 6 months later for symptoms of PTSD

Compared to a control group (who didn’t receive any therapy) the flooding group have fewer terrifying flashbacks

33
Q

Outline 3 strengths of flooding for the treatment of phobias?

A
  • quick compared to systematic desensitisation which takes up to 12 sessions where as flooding is usually one session
  • has research evidence which shows its effective - Keane 1989
  • cheaper - can be offered by NHS
34
Q

Outline 2 strengths of systematic desensitisation for the treatment of phobias?

A
  • you are able to go at your own pace, can be more comfortable compared to flooding
  • has research evidence that shows it’s effective - gilroy 2003
35
Q

Outline 2 weaknesses of systematic desensitisation for the treatment of phobias?

A
  • have to be committed as it can take up to 12 sessions, may be doing 2 a week
  • cost - due to the number of sessions, probably wont be offered on NHS
36
Q

Outline 2 weaknesses of flooding for the treatment of phobias?

A
  • can be highly distressing for the individual undergoing treatment - could increase anxiety
  • unethical compared to systematic desensitisation as the individual has no control and cannot leave if they are too scared - put under immense distress and can be left with lasting effects of this distress
37
Q

Outline why flooding can be a risky option for treatment of phobias - provide research evidence for this?

A

individual has no control and cannot leave if they are too scared - put under immense distress - Barrett (1969) gave a girl a session of flooding who was scared of snakes. She associated the snakes with closing her eyes and could never sleep again after the session (she saw snakes when her eyes were closed)
