Exposure therapy
9 important questions on Exposure therapy
Give an example of the classical conditioning of social fear
NS --> groep mensen
CS (groep mensen) - UCS (pesten) --> UCR (angst)
CS (groep mensen) --> CR (angst)
What is operant conditiong?
How can you apply the principles of UCS, UCR, CS and CR to exposure therapy?
(exposure instead of avoidance = negative reward)
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What does the Mowrer Two-process model state?
- Fear is origionally learned through classical conditioning
- Fear is maintained by operant conditioning
- Therapy must focus on extinction of CS --> CR, but also on breaking the cycle of avoidance of the feared stimuli, which would prohibit extinction.
What does the emotional process theory of (Kozak and Foa) state?
- Make a distinction between normal and pathological fear structures.
- Stress the importance of the 'meaning' element in the fear structure, for determining whether a fear structure leads to avoidance.
- A pathological fear structure is a fear structure in which the association between the stimulus, response and meaning representations doesn't reflect reality.
- Effective exposure = forming a correct fear structure
- Correct fear structure is changed, through activation + the introduction of new information that is incompatable with the old information.
- Fear structure is changed after exposure
- Caused by fear habituation (fear reduction during sessions and over course of therapy)
What does the inhibitory learning theory state?
- Effective exposure = the formation of a new, competing non-fear structure
- New information, incompatible with old info must be introduce to form a new structure.
- Enhancing the accessibility and retrievability of non-threat associations.
- Fear structure remains intact
- Fear toleration
- After exposure the new and old fear structure compete for retrieval.
What does the evidence indicate in relation to emotional processing theory and the inhibitory learning theory?
- Inhibitory learning: Inconclusive empirical evidence.
What are the most important differences between the emotional processing theory and the inhibitory learning theory?
ILT: nieuwe non-fear structure wordt gevormd. Huidige fear structure blijft bestaan maar leert men tolereren. Beide structureren strijden om voorrang bij herhaalde situatie.
Which three primary types of exposure exists?
- In vivo (real life) exposure
- Imaginal exposure
- Interoceptive exposure (stilstaan bij de somatische signalen van angst)
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
