9. Saavedra and Silverman (2002) - Learning Approach - done Flashcards
Aim of SS (2)
understand the causes of button phobia
to treat the phobia using disgust and fear responces
Research method/ design of SS (2)
case study - one participant
data was collected using self report measures
Sample of SS (3)
9 year old Hispanic american boy
phobia developed when he was 5 years old when he knocked over the bowl of buttons in front of his class
opportunity sampling - both mother and child gave consent
methodology of SS (2)
DSM-IV was used to diagnose his phobia
Feeling thermometer was used 9 point scale of disgust was used throughout the treatment
Procedure and interventions of SS (4)
- disgust/fear hierarchy was made - 0 large denim buttons and 8 - small plastic buttons –> then asked to rate scenarios with buttons (on the feelings thermometer)
Intervention:
Positive reinforcement therapy –> based on operant conditioning. Boy was rewarded for showing less fear and handling them. The mother would provide the positive reinforcement
Imagery exposure –> based on classical conditioning. Imaging the buttons falling on him and consider how they looked and felt etc. the imagining went with the fear hierarchy from 0 to 8
they used self control methods and cognitive strategies to change his way of thinking
Results of SS (3)
PRT - he approached the buttons more as sessions went –> his distress levels went higher Despite the behavioural change, evaluative reactions are unchanged or have increased.
IE - successful in reducing the level of distress. In the beginning he rated the experience 8 then middle 5 then 3.
They did follow up after 6 months then 12 and his results on DSM – he did not meet the criteria for phobias
Conclusion of SS (2)
Emotions and cognitions relating to disgust are important in the development and maintenance of a phobia.
Imagery exposure has a long-term effect on reducing distress relating to specific phobias as it tackles negative evaluations
Strengths of SS (5)
+ high validity – was studied for a long period of time
+standardised measures – feeling thermometer
+Quantitative data – feeling thermometer
+Qualitative data – interview with mom and kid
+Got rid of phobia (high ethics –> better than they came)
Weakness of SS (4)
- hard to generalise as it is one boy and a specific phobia
- subjective –> created his own hierarchy and personal ratings
- worked with the experimentors – may contain experimentor bias
- boy may show demand characteristics – was aware he was doing therapy etc may have affected the results
