Exposure therapy

9 important questions on Exposure therapy

Give an example of the classical conditioning of social fear

UCS (pesten) --> UCR (angst)

NS --> groep mensen

CS (groep mensen) -  UCS (pesten)  --> UCR (angst)

CS (groep mensen) --> CR (angst)

What is operant conditiong?

Theory that can help explain why a behaviour is maintained through the consequence of the behaviour, trough reinforcement (rewards) and punishments.

How can you apply the principles of UCS, UCR, CS and CR to exposure therapy?

Therapy in which and individually is repeatedly and purposefully exposed to an fear (CR) provoking stimuli (CS) , in the absence of the repeated aversive outcome (UCS) --> werethrough the CS --> CR developed. Leads to extinction of association between CS --> CR.

(exposure instead of avoidance = negative reward)

What does the Mowrer Two-process model state?

Model that can help explain how fear in anxiety disorders is maintained. Integrated the concept of avoidance into the concept of operant conditioning of Skinner.

  • 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?

- EPT: habituation is not predictive for treatment outcomes
- Inhibitory learning: Inconclusive empirical evidence.

What are the most important differences between the emotional processing theory and the inhibitory learning theory?

EPF: focus op aanpassen fear structure naar correcte variant, verminderde angst door gewennign

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?

  1. In vivo (real life) exposure
  2. Imaginal exposure
  3. Interoceptive exposure (stilstaan bij de somatische signalen van angst)
