Exposure Therapy with Retrieval
Participants will receive one-session exposure therapy (up to 92 minutes) for fear of spiders or fear of snakes. Thirty minutes prior to exposure therapy, participants will receive a fear retrieval trial, which is a brief exposure to the feared stimulus (snake or spider). Based on recent basic science research, the fear retrieval trial is expected to enhance the efficacy of exposure therapy.
Exposure Therapy with Compound Extinction
Participants will receive one-session exposure therapy (up to 92 minutes) for fear of spiders or fear of snakes. As a component of therapy, participants will receive compound extinction, which consists of exposure to two feared stimuli simultaneously (two spiders or two snakes). Based on recent basic science research, compound extinction is expected to enhance the efficacy of exposure therapy.
Exposure Therapy with Retrieval and Compound Extinction
Participants will receive one-session exposure therapy (up to 92 minutes) for fear of spiders or fear of snakes. Thirty minutes prior to exposure therapy, participants will receive a brief fear retrieval trial. As a component of therapy, participants will also receive compound extinction.
Therapist-guided Exposure Therapy
Participants will receive one-session exposure therapy (up to 92 minutes) for fear of spiders or fear of snakes.
