Eight pairs of DSM-III-R snake phobic subjects (Ss) were exposed to a caged snake while seated in front of a package-conveyor apparatus during eight 4-minute trials. Heart rates and skin-conductance levels were recorded before and during each of the eight trials. Self-reports of fear were obtained after each trial. One S in each pair controlled the conveyor(More)
Factor analysis of the Dental Fear Survey disclosed three stable and reliable factors. The first factor related to patterns of dental avoidance and anticipatory anxiety. The second factor related to fear associated with specific dental stimuli and procedures. Factor three concerned felt physiologic arousal during dental treatment. Cross validation showed(More)
Two hundred randomly selected student participants (139 females, 61 males) responded initially to questionnaires that quantified variables such as state and trait anxiety, anxiety sensitivity, claustrophobia, and panic/agoraphobia. Later they were informed that a mock magnetic resonance imaging (MRI) procedure was upcoming, and were prompted to provide(More)
A conceptualization of claustrophobia [Rachman, S., & Taylor, S. (1993). Analyses of claustrophobia. Journal of Anxiety Disorders, 7, 281-291] was evaluated in the context of magnetic resonance imaging. One hundred eleven students responded to questionnaires that quantified fear of suffocation, fear of restriction, and sensitivity to anxiety symptoms.(More)
Fear sometimes returns after attenuation via exposure. Return of fear is poorly understood due to conflicting results from diverse experiments. This article reports on two experiments in which claustrophobic fear during mock diagnostic imaging was attenuated and allowed to return so the experiments could be evaluated and return of fear studied. Attentional(More)
Visual change detection mirrors conscious attention. In the flicker task, pairs of scenes are presented rapidly; the second scene differs from the first, and the participant identifies the change. Change occurs in either a central-interest region or marginal-interest region of the scene. Detecting change in a marginal-interest region requires that attention(More)
Heart beats, skin conductance, and subjective fear levels were recorded among eight pairs of DSM-III-R spider-phobic subjects (Experiment 1) and among eight pairs of DSM-III-R cockroach-phobic subjects (Experiment 2) who were exposed simultaneously to an approaching specimen during eight 4-minute trials. Control over the approach of the specimen alternated(More)
The hypothesis was tested that patients diagnosed with myofascial pain-dysfunction (MPD) syndrome display a stereotypic response to stress via increased activity in the facial muscles. Twenty MPD patients and 20 matched control subjects were seated and exposed to affectively neutral, then stressful, then affectively neutral film clips. During film viewing,(More)
Studied the effects of aversive imagery gradation and muscular relaxation as procedural variables within desensitization by using (pre-vs. posttreatment) peripherally cued electrodermal responsivity as the dependent-variable measure of fear. There was no evidence that experimental desensitization or any of its procedural components yielded attenuated(More)
Fear sometimes returns after successful fear attenuation via in vivo exposure to fear signals. Post-treatment return of fear is of considerable interest both practically and theoretically, but factors associated with return of fear are poorly understood due to conflicting results from procedurally diverse experiments. This paper reports two very similar(More)
