Cognitive theories of anxiety also illustrate how theory is applied to develop
a treatment. There are many different cognitive models of anxiety, but all
are similar in that they assume that there is a cognitive cause of the fear
state. This cognitive step is sometimes called an irrational belief. A cognitive
theorist might explain Little Hans’s fear in the following way: Hans is afraid
of horses because he has some irrational belief that horses are dangerous.
The specific belief might be “The horse will bite me” or “The horse might
get spooked and run into me” or even “Horses have germs, and if I go near
one, I’ll catch its germs and get sick.” The theory assumes that anxiety will
stop when the irrational belief is eliminated. Thus, a cognitive therapist
would first carefully question Hans to find out the specific irrational belief
causing his fear. Once that is determined, the therapist would use persuasion,
logical reasoning, and evidence to try to change the belief. (Little
Hans was used here only to continue with the same example. A therapist
probably would not try to reason with a five-year-old, and a different treatment
would be used. Cognitive therapies are more commonly used with
adults.)
