Pavlov’s extinction theory favors that extinction can inhibit individual’s
fear response to the conditioned stimulus. However, extinction scenario dependence
can induce the recurrence of Extinguished fear, which means that exposure therapy
based on extinction theory has limitations. Clinically, patients with anxiety disorders
who are treated with exposure therapy are likely to exhibit behavioral performance
of renewal or spontaneous recovery, which brings great difficulties to treatment. The
core theoretical basis of exposure therapy is the extinction of fear memory. Extinction
training can inhibit the individual’s fear response to a conditioned stimulus (CS).
However, extinction training forms context-dependent learning, which will lead to the
relapse of the fear response that already has extinguished. Therefore, how to reduce
patients’ fear relapse has become a key issue in the treatment of anxiety disorders.
Based on the possibility that drug intervention may have side effects on patients'
bodies, this paper focuses on the all-natural, non-invasive and effective methods of
fear relapse intervention, aiming to provide appropriate guidance and suggestions for
psychologists.
