These pathways ...
The goal of the therapy is for the individual to learn how to cope with and overcome their fear in each level of an exposure hierarchy.

The least anxiety-provoking situations are ordered at the bottom of the hierarchy while the most anxiety-provoking situations are at the top. Exposure hierarchies typically consist of 10-15 items and will guide the client’s exposure practices. [1] An abbreviated example of an exposure hierarchy is pictured in Image 1.

[ 49 ] These responses are triggered by the sympathetic nervous system , but, in order to fit the model of fight or flight, the idea of flight must be broadened to include escaping capture either in a ...

In humans and other animals, fear is modulated by cognition and learning. Thus, fear is judged as rational and appropriate, or irrational and inappropriate.
