Learning Objective
Describe behavioral modification techniques, including systematic desensitization, exposure therapy, flooding/implosion, and aversive conditioning, and explain their mechanisms and clinical applications.
Classical Conditioning–Based Techniques
Systematic Desensitization
- Used to treat anxiety disorders and phobias.
- Based on counterconditioning: pairing a feared stimulus with a relaxation response.
Steps:
- Create a hierarchy of fear-eliciting stimuli (least to most stressful).
- Pair each stimulus with relaxation techniques.
- Gradually progress up the hierarchy until the fear response is extinguished.
Example:
Imagine being in a spider-filled room while practicing deep breathing.
Activity
Exposure Therapy
Steps:
- Patient is directly exposed to the feared object or situation until fear extinguishes.
- A hierarchical approach is used (gradual exposure).
Example:
Climbing higher floors for fear of heights.
Flooding / Implosion
Steps:
- Flooding: Immediate exposure to maximal anxiety-provoking stimulus (no hierarchy).
- Implosion: Imagined version of flooding.
Example:
Locked in a room full of spiders to overcome arachnophobia.
Aversive Conditioning
Steps:
- Undesired behavior is paired with an aversive stimulus.
- Goal: Reduce or eliminate the undesired behavior.
Example:
- Alcoholism treatment with disulfiram → makes the patient sick if alcohol is consumed.
