Phobias - characteristics, explanations and treatment Flashcards
What is a phobia?
A persistent, extreme and irrational fear of a specific object or situation which disrupts everyday life. The fear is disproportionate to the actual danger.
What are the 3 categories of phobias
Specific - fear and avoidance of a particular object or situation
Social - fear of humiliation/embarrassment and being judged in social situations
Agoraphobia - fear of being outside or in a public place
Behavioural characteristics of phobias
Panic - people may panic which activated fight or flight response. Show behaviours like crying and screaming
Avoidance - going into a lot of effort to avoid coming into contact with their phobia - causes disruption to a normal everyday life
Emotional characteristics of phobias
Anxiety - phobias are classified as anxiety disorders and involve emotional responses like anxiety and fear.
Fear - response produced when a person thinks about their phobic stimulus. These emotional responses are often unreasonable
Cognitive characteristics of phobias
Selective attention - only concentrating on the phobia and nothing else
Irrational beliefs
Cognitive distortions- perception of phobic stimulus may be distorted and inaccurate
Behavioural approach to explaining phobias - what are the key assumptions of the behaviourist approach
Only actions/behaviour that can be observed and measured objectively should be studied
The basic processes of learning occur in all species
All behaviour is determined by environmental stimuli and behaviour is learned through classical and operant conditioning
How does the two process model explain all phobias
Phobias are initially caused through classical conditioning and maintained over a persons lifetime by operant conditioning
Classical conditioning explanation example using phobia of dogs
Pain (UCS) causes Fear (UCR)
Dog (NS) causes no response
Pain (UCS) + Dog (NS) causes Fear (UCR
Dog (CS) causes Fear (CR)
Key research - Watson and Rayner ‘Little Albert’
Aim - to establish whether emotional responses such as fear could be conditioned
Procedure - Albert at 9 months old was presented with various stimuli to see his reaction such as a dog, a rabbit, a monkey, masks with and without hair, cotton wool, burning newspapers and a hammer striking a steel bar behind his head. Only the last of these frightened him and the rest were neutral as fear wasn’t produced.
Results - At 11 months the rat and the hammer striking the steel bar were presented together which occurred seven times in total over the next 7 weeks and at this time the rat alone produced fear. The dear response transferred to the rabbit, the dog, cotton wool showing generalisation but not to building blocks and the hair of observers showing discrimination.
Conclusion - classical conditioning caused fear and this was still evident one month later
Classical conditioning equation for Little Albert study
Before conditioning
Steel bar with hammer (UCS) causes fear (UCR)
During conditioning
Steel bar with hammer (UCS) + rat (NS causes fear (UCR)
After conditioning
rat (CS) causes fear (CR)
Operant conditioning explanation of phobias
According to operant conditioning, phobias can be negatively reinforced. The behaviour is strengthened because an unpleasant consequence is removed which is rewarding. For example a person with a phobia of dogs may avoid parks or cross to another side of the road when they see a dog to avoid the unpleasant situation of anxiety and fear
Evaluation of behaviourist explanation of phobias
STRENGTHS
- research support from little Albert
- useful in developing therapies
- practical applications to flooding and systematic desensitisation
LIMITATIONS
- two process model doesn’t account for the cognitive processes associated with phobias
- not all phobias occur after a bad experience
- deterministic and ignores free will
- we may be predisposed to so,e phobias eg snakes to give human ancestors a survival advantage - hard wired and not learned
3 steps of systematic desensitisation as a treatment to phobias
1 - relaxation eg breathing techniques, meditation, progressive muscle relaxation
2 - anxiety hierarchy - formed with patient and therapist from most frightening and least frightening stimulus
3 - exposure - gradually exposed to anxiety hierarchy whilst doing relaxation techniques. Each stage must be mastered before moving to the next.
Difference between in vivo and in vitro
In vivo - person exposed to real feared stimulus
In vitro - non contact, uses pictures and images
Flooding as a treatment of phobias
This approach directly exposes clients to the objects or situations they fear - there is no gradual exposure it is immediate. The patient is exposed to the phobia without any option for avoidance, patient is initially overwhelmed but this feeling subsides, patient recognises anxiety levels have dropped and realise phobic stimulus is harmless and are no longer scared
