The technique is based on the principle of extinction, which suggests that when a person is exposed to a feared stimulus repeatedly and for a prolonged period without any negative consequences occurring, their fear response will diminish.
Flooding aims to help individuals confront their fears directly and experience the absence of harm or negative outcomes, leading to the extinction of their anxiety response.
For example, a claustrophobic will be locked in a closet for 4 hours, or an individual with a fear of flying will be sent up in a light aircraft.
Flooding aims to expose the sufferer to the phobic object or situation in a safe and controlled environment for an extended period. Unlikesystematic desensitization, which might use in vitro or virtual exposure, flooding generally involves vivo exposure.
Fear is a time-limited response. At first, the person is in extreme anxiety, perhaps even panic, but eventually, exhaustion sets in, and the anxiety level decreases.
Of course, normally, the person would do everything possible to avoid such a situation. Now, they have no choice but to confront their fears, and when the panic subsides, they find they have come to no harm. The fear (which, to a large degree, was anticipatory) is extinguished.
Prolonged intense exposure eventually creates a new association between the feared object and something positive (e.g., a sense of calm and lack of anxiety). It also prevents the reinforcement of phobia through escape or avoidance behaviors.
Critical Evaluation
Flooding is rarely used, and it can be dangerous if you are not careful. It is not an appropriate treatment for every phobia.
It should be used cautiously as some people can increase their fear after therapy, and it is impossible to predict when this will occur.
Wolpe (1969) reported the case of a client whose anxiety intensified to such as degree that flooding therapy resulted in her being hospitalized.
This is a problem, as an existing treatment before completion will likely strengthen rather than weaken the phobia.
However, one application is for people who fear water (they are forced to swim out of their depth). It is also sometimes used with agoraphobia.
In general, flooding produces results as effective (sometimes even more so) as systematic desensitization.
