Electroencephalographic cortical event-related potentials (ERPs) are affected by information processing strategies and are particularly appropriate for the examination of hypnotic alterations in perception. The effects of positive obstructive and negative obliterating instructions on visual and auditory P300 ERPs were tested. Twenty participants,(More)
On the bases of Hilgard's neodissociation theory and Spano's (1982) sociocognitive theory, volunteers stringently selected for high (N = 10) and low (N = 10) hypnotizability were exposed to a cold pressor pain test during counterbalanced conditions of waking relaxation, distraction, and hypnosis. To better discriminate between hypnosis and distraction(More)
Barabasz, Barabasz, Jensen, Calvin, Trevisan, and Warner (1999) showed that, when subjects are stringently selected for hypnotizability and responses are time locked to events, robust markers of hypnotic responding emerge that reflect alterations in consciousness that correspond to subjects' subjective experiences of perceptual alteration. To further test(More)
Visual memory recall in hypnosis was investigated. To address criterion shift problems in previous studies, both forced and non-forced recall procedures were used. Previous methodological weaknesses with regard to hypnotizability and hypnotic depth were also addressed. Over 300 volunteers were screened for hypnotizability using the Harvard Group Scale of(More)
BACKGROUND AND PURPOSE The sensitivity to the intoxicating effects of alcohol as well as its adverse medical consequences differ markedly among individuals, which reflects in part differences in alcohol's absorption, distribution, metabolism, and elimination (ADME) properties. The ADME of alcohol in the body and its relationship with alcohol's brain(More)
We sought to determine: 1) whether a simple hypnotic induction with an alprazolam experience derived suggestion could recreate the subjective effects of alprazolam (Xanax), 2) whether the effects of alprazolam are greater than the effects of hypnosis plus this suggestion, and 3) whether the effects of hypnosis plus this suggestion were greater than the(More)
Methylphenidate (MP) (Ritalin) is widely used for the treatment of attention deficit hyperactivity disorder (ADHD). It is a chiral drug, marketed as the racemic mixture of d- and l-threo enantiomers. Our previous studies (PET and microdialysis) in humans, baboons, and rats confirm the notion that pharmacological specificity of MP resides predominantly in(More)
In order to assist individuals with disabilities in education/employment settings, it may be necessary to provide special devices - either commercially available or custom made - so that the person will be able to conduct his/her work properly. In order to obtain these devices, an information retrieval system has been developed that presents the user with(More)
