![]() ![]() Exposure therapy, or the repeated presentation of a fear-evoking CS in the absence of aversive consequences, is currently the most effective treatment for anxiety disorders ( Foa, 2000). Ambient neutral stimuli that are present when an individual is exposed to a traumatic event (or unconditioned stimulus US) can become conditioned stimuli (CSs) that evoke conditioned fear responses. Thus, the results remain inconclusive regarding spontaneous recovery and the timing of extinction and are discussed in terms of performing translational studies of fear in humans.Īnxiety disorders such as specific phobia and posttraumatic stress disorder (PTSD) can be conceptualized as the result of fear conditioning in affected patients ( Bouton, Mineka, & Barlow, 2001). With differential conditioning, there were no differences in context conditioning and the Immediate group displayed less spontaneous recovery. In the single cue paradigm, the Immediate and Delayed groups exhibited differences in context, but not fear, conditioning. Testing for spontaneous recovery occurred 96 hr after acquisition. Using separate single-cue and differential conditioning paradigms, participants were fear conditioned and then underwent extinction either 10 min (Immediate) or 72 hr (Delayed) later. For this reason, we performed an in-depth parametric analysis of human fear extinction using fear-potentiated startle. However, a limited number of human extinction studies have shown that short interval extinction does not prevent the return of fear. Animal studies suggest that spontaneous recovery can be abolished if extinction occurs within minutes of acquisition. Extinguished fear often reappears after extinction through spontaneous recovery.
