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)
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)
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)
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)
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)
Twenty carefully selected snake phobics were exposed to a caged snake for eight trials via a conveyor apparatus. During the first and eighth trials the subjects brought the snake toward themselves as closely as tolerable; records were kept of the end-of-trial distances remaining between the subject and the snake. For the six intervening trials the(More)
701 dental-school outpatients rated the degree of fear occasioned by each of 60 events that occur routinely during dental treatment. The 4,206 ratings then were subjected to principal components factor analysis with oblique rotation. Four meaningful factors were deduced: fear of pain and its antecedents, anticipatory fear, fear of negative evaluation, and(More)
Relationships between sleep-related bruxing, electroencephalographic phenomena, and other physiologic variables are reviewed. Bruxing occurs during all sleep stages but occurs disproportionately during stage 2 and REM. Bruxing during deeper sleep stages frequently is followed by a transition to lighter sleep. Bruxing occurs in conjunction with K-complexes(More)
This article reviews published research on the use of EMG-activated feedback paradigms to modify nocturnal bruxism. The first three sections review naturalistic trials, laboratory studies, and comparisons of feedback paradigms with alternative treatment/management approaches. The fourth section overviews several sources of theoretical guidance for further(More)
