The Behavioural Approach to Explaining and Treating Phobias

Cards (30)

  • what are the main assumptions of the behavioural approach
    ->psychologists should only study observable, quantifiable behaviour
    ->all behaviour is learned
    ->humans are no different than humans and should not be regarded as complex
    ->research on animals behaviour is directly relevant to humans
  • what are the key explanations of phobias using the behaviourist approach?
    ->phobias can be learned through classical and operant conditioning
  • explain the two-process model
    ->proposed by Hobart Mowrer (1960)
    ->the acquisition (onset) of phobias is seen as occurring directly through classical conditioning
    ->e.g, by the experience of traumatic event, like being bitten by a dog
    ->the maintenance of phobias is seen as occurring through operant conditioning, where avoiding or escaping from a feared object/situation acts as a negative reinforcer (the reward being the reduction of anxiety)
    ->this reinforces the avoidance response (makes it more likely to occur again)
  • explain the acquisition of a phobia through classical conditioning
    ->classical conditioning is learning through association
    ->classical conditioning involves learning to associate something which we initially have no fear of (called neutral stimulus/NS) with something that already triggers a fear response (unconditioned stimulus/US)
  • case study for classical conditioning
    ->Little Albert
    ->Watson and Rayner (1920) conditioned Little Albert to be scared of a white rat
    ->They noticed he was naturally frightened of a loud banging noise and he was unafraid of the rat
    ->they then paired together the loud noise with the white rat lots of times
    ->eventually, they learnt to associated the two together until the white rat only was enough to produce a fear response
    ->Albert also became scared of other white fluffy things like sheep and Santa's beard- this is known as stimulus generalisation
  • What makes the Little Albert case highly unethical and controversial?
    ->Watson and Rayner never removed this conditioning and it damaged Little Albert permanently
  • what is a strength of the two-process model
    ->it has real-world application in exposure therapies (such as systematic desensitisation)
    ->the distinctive element of the two-process model is the idea that phobias are maintained by the avoidance of the phobic stimulus
    ->once the avoidance behaviour is prevented, it ceases to be reinforced by the experience anxiety reduction and avoidance therefore; it declines
    ->in behavioural terms, the phobia is the avoidance behaviour so when this avoidance is prevented, the phobia is cured
  • why is the fact that the two-process model having a lot of real-world application a strength?
    ->it shows the value of the two-process approach because it identifies a means of treating phobias
  • what is another strength of the two-process model?
    it has evidence for a link between bad experiences and phobias
    ->W&R found how Little Albert was conditioned into having a phobia of the white rat by pairing the rat (UCS) with a loud noise (NS) which produced an UCR of fear
    ->the rat over time is now a learned stimulus (CS) that produces a conditioned response (fear)
  • case study by Ad De Jongh
    ->(2006) found that 73% of people with a fear of dental treatment had experienced a traumatic experience
    ->mostly involving dentistry when compared to a control group (21% experienced a traumatic event
  • why is the fact that the two-process model having evidence for a link between bad phobias a strength ?
    it's a strength because it increases the validity of the two-process model, proving that traumatic experiences can lead to phobia
  • give a counter-argument of the two-process model
    ->not all phobias appear following a bad experience
    ->infact, some common phobias such as snake phobias occur in populations where very few people have any experience of snakes let alone traumatic experiences
    ->also, not all frightening experiences lead to phobias
    ->this means that the association between phobias and frightening experiences is not as strong as we would expect if behavioural theories provided a complete explanation
  • what is a limitation of the two-process model
    ->it doesn't account for the cognitive aspects of phobias
    ->behavioural explanations, including the two-process model, are geared towards explaining behaviour
    ->in case of phobias, the key behaviour is avoidance of the phobic stimulus
    ->however, we know that phobias are not simply avoidance responses-they also have a significant cognitive component
    ->e.g, people hold irrational beliefs about the phobic stimulus (Such as thinking that a spider is dangerous)
    ->it explains avoidance but doesn't offer adequate explanation of phobic cognitions
  • why is the lack of account of the cognitive aspects of phobia limitation of the two-process model?
    ->it doesn't completely explain the symptoms of phobias
  • what are the two different ways proposed by the behaviourist approach of treating phobias?
    ->systematic desensitisation
    ->flooding
  • explain systematic desensitisation
    ->it's a behavioural therapy designed to gradually reduce phobic anxiety through the principle of classical conditioning
    ->if a person learns to relax in the presence of the phobic stimulus, they'll be cured
    ->a new response to the phobic stimulus is learned and so the phobic stimulus is paired with relaxation instead of anxiety
  • define counter-conditioning
    the learning of a different response
  • describes the stages of sytematic desensitisation
    ->clients are taught relaxation techniques e.g breathing exercises and clients can be taught to imagine themselves in relaxing situations
    ->with the help of a therapist, clients construct an anxiety hierarchy- a list of feared objects or situations from the least to the most feared
    ->in the presence of the therapist, the client then confronts each item in the hierarchy while they are in a state of deep relaxation- they start with the least feared item and move on once they feel relaxed and unafraid in it's presence
  • what is a strength of using systematic desensitisation to help get rid of phobias?
    ->there's supportive evidence for it's effectiveness
    ->Gilroy (2003) followed 42 people who had SD (systematic desensitisation) for spider phobia in three 45-minute sessions
    ->at both three and 33 months, the SD group were less fearful than a control group treated by relaxation without exposure
    ->in a recent review, Wechster (2019) concluded that SD is effective for specific phobia, social phobia and agoraphobia
  • why is the availability of supporting evidence for using systematic desensitisation a strength?
    it's a strength because SD is likely to be helpful for people with phobias and people can be treated through counter-conditioning
  • what is a limitation of using systematic desensitisation as a treatment for phobias?
    ->it's not effective in treating all phobias
    ->patients with phobias which have not developed through a personal experience (classical conditioning), such as fear of snakes, are not effectively treated using SD
    ->some psychologists believe that certain phobias have an evolutionary survival benefit and are not the result of learning
  • why is it a limitation that SD cannot be effective in treating all phobias?
    ->it's a limitation of SD it's ineffective in treating evolutionary phobias which have an innate basis
  • what is flooding?

    ->it's an approach that directly exposes clients to the object or situations they fear but without a gradual build up in an anxiety hierarchy
    ->it involves immediate exposure to a very frightening situation
  • example of flooding
    ->someone with a fear of heights is taken to the top of a tower and encouraged to stay there
    ->in theory, flooding the client-exposing them repeatedly to the feared stimulus will allow them to see that there's no basis for their fear
  • what happens when flooding works?
    extinction of the fear happens
  • explain how flooding works
    ->flooding stops phobic responses very quickly
    ->this may be without the option of avoidance behaviour, the patient quickly learns that the phobic stimulus is harmless
    -> a learned response is extinguished when the conditioned stimulus (e.g dog) is encountered without the unconditioned stimulus (e.g being bitten)
    ->the result: the conditioned stimulus no longer produces the conditioned response (fear)
    ->in some cases, the patient achieves relaxation in the presence of the phobic stimulus simply because they become exhausted by their own fear response
  • what's a strength of using flooding as a method to get rid of a phobia?
    ->it's highly cost-effective
    ->clinical effectiveness means how effective a therapy is at tackling symptoms
    ->however when we provide therapies in health systems like the NHS, we also need to think about how much they cost
    ->a therapy is cost-effective, if it's clinically effective and not expensive
    ->flooding can work in as little as one session, opposed to 10+ SD sessions to achieve the same results even allowing for a longer session (perhaps 3 hours)
  • why is the method flooding being cost-effective a strength?
    ->it means that more people can be treated at the same cost with flooding than SD or other therapies
  • what is a limitation of using flooding to treat phobias?
    ->it's a highly unpleasant experience
    ->confronting one's phobic stimulus in an extreme form provokes tremendous anxiety
    ->Schumacher (2015) found that participants and therapists rated flooding as significantly more stressful than SD
    ->this raises ethical issues for psychologists of knowingly causing stress to their clients, although this isn't a serious issues provided they obtain informed consent
    ->more seriously, the traumatic nature of flooding means attrition (dropout) rates are higher than SD
  • why is flooding being an highly unpleasant experience a limitation of this type of treatment?

    ->It means overall, therapists may avoid using this treatment
