Background: Needle phobias are common in children and adults worldwide. One effective intervention for this phobia is exposure therapy where a participant is gradually exposed to increasing levels of the fear-evoking stimulus while differential reinforcement is applied. This intervention, however, may be difficult to implement with some medical…

Safety signals provide "relief" through predicting the absence of an aversive event. At issue is whether these signals also act as instrumental reinforcers. Four experiments were conducted using a free-operant lever-press avoidance paradigm in which each press avoided shock and was followed by the presentation of a 5-sec auditory safety…

Two studies using an ABA design examined the Extinction and renewal of conditioned barpress suppression. Following lights-off and foot shock pairings in Context A, rats were placed in Context B and were given either a standard counterconditioning procedure where the lights-off CS was paired with a novel food US delivered freely or a modified…

Stimulus fading in the form of gradually increased exposure to a fear-evoking stimulus, often combined with differential reinforcement, has been used to treat phobias in children who are otherwise normal and in children with autism. In this investigation, we applied stimulus fading plus differential reinforcement with an adolescent with autism and…

The subject-controlled graduated exposure of a snake with feedback of exposure times resulted in significantly less avoidance behaviors for snake-phobic subjects than for control snake-phobic subjects who did not receive therapy. (Author)

From 300 introductory psychology students, 40 female "snake phobics" were selected to test the hypothesis that distraction paired with fearful imagery is effective in alleviating the "phobia." Subjects were divided into three treatment groups and a control group: H+PI (fear hierarchy plus pleasant imagery as distraction), H+P…

Two autistic children were treated for specific fears. Children were exposed gradually to fearful situations, with mothers serving as therapists and reinforcers. Five-month and one-year follow-up assessments with one child showed maintenance of treatment effects. (Author/DB)

An undergraduate's problem consisted of recurrent, frightening, and uncontrollable visual sensations. The client cooperated in exercises which involved producing, maintaining, and dismissing the sensations at the verbal signals of the therapist. At both the 45- and 85-day follow-up, the client reported substantially reduced incidence of the…

Examined the relations among self-esteem, perceived competency to cope, and actual coping behaviors following a threat communication. Manipulated threat level of a tetanus communication and fear level of an antismoking film. Results indicated low-esteem subjects showed coping deficits in both experiments, with positive feedback reversing the…

This study of the outcomes of treatment of three children with autism, to reduce fear of dental examinations, found that the children could be trained through a combined desensitization, symbolic modeling, and reinforcement treatment package to undergo a dental exam in an analog setting, and the training could generalize somewhat to a clinical…
