An Investigation Of Some Electrophysiological Concomitants Of Hallucinations, Ronald S. Golemba

Theses and Dissertations (Comprehensive)

The present research was designed to determine if a single LSD experience produces a detectable change in the electrical potential of the brain, and if so, how long that change lasts, and to examine the changes in the electrical potential of the brain associated with chemogenic and hypnogenic hallucinations. Four studies were conducted measuring the electrical potential between the front and back of the head in monkeys and humans. The frontal potential was shown to shift negatively with the use of LSD-type psychedelics but not with marijuana compounds. LSD caused the potential in humans to shift into the range commonly …

Voluntary Control Of Gsr Using Continuous Visual Display And Simultaneous Changes In Other Autonomic Functions, Laurence E. Boyce

Masters Theses

Using 28 male undergraduate university students provided with continuous oscilloscope display of basal skin resistance, this study investigated voluntary control of the GSR and concurrent changes in respiration. It was found, given feedback, subjects could voluntarily raise or lower their GSR. Subjects instructed to increase their GSR (N-14) could do so within the first trial session. However, subjects instructed to decrease their GSR (N-14) required additional practice. With less than 20 minutes of practice all subjects were able to reach a criterion of 2,500 ohms change from their basal level. Subjects increasing their GSR were found to have a significant …

The Effects Of Cs Habituation And Duration Of The Directional Modification Of The Cardiac Response In The Guinea Pig (Cavia Procellus), Ray Charles Larson

All Master's Theses

The present experiment examined the effects of CS habituation and two different levels of CS duration (60 versus 6 sec) on the directional modification of the conditioned cardiac response in the guinea pig. The results indicated that the only reaction to the CS, regardless of prior habituation or CS duration, was a decelerative conditioned HR response. However, habituation to a CS prior to classical aversive conditioning was found to attenuate the magnitude of the bradycardia CR that developed. The bradycardia CR was discussed in terms of being a cardiac component of the orienting response.

Effects Of A Series Of Nurse-Patient Interactions On Multiple Sclerosis Patients, Lynne Campbell

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of the study was to learn whether a series of nurse-patient interactions would result in changed psychophysiologic functioning in multiple sclerosis patients.

Psychophysiologic relationships were described in the theoretical framework. Literature, reviewed in the areas of disease description and psychotherapeutic approaches to treatment, indicated that there is a high incidence of multiple sclerosis in the United States; that symptoms often include psychological alterations; that there is an emotional component to the illness; that these patients have a need for a psychotherapeutic relationship; and that psychotherapeutic approaches may have beneficial psychophysiologic effects.

Two groups of multiple sclerosis subjects were …

Conservatism In A Bayesian Probability Situation As A Function Of The Sex Of The Subject, Paul Frederick Miller

All Master's Theses

The present study was designed to examine whether the conservatism present in a Bayesian probability situation could be partially attributable to the sex of the subjects performing the task. The experimental design required that the subjects estimate the probabilities of occurrence of two independent events. They were then given an opportunity to revise their estimates as additional information was experimentally introduced into the situation. These estimates were compared to estimates calculated from Bayes’ theorem.

The Relative Effect Of Time Of Reinforcement And Pre-Reinforcement Activity On The Learning Of Meaningful Verbal Material, Daisuke Bill Nakashima

All Master's Theses

The present study was designed to compare the relative effects on learning and retention of (1) time of reinforcement, (2) pre-reinforcement activity, and (3) the interaction of the temporal interval and activity. The hoped-for criterion was the retention of six principles.

Development Of Circadian Sleep-Wakefulness Rhythm In A Healthy Boy Gauged By Circadian Quotients, Ellen Reeker, Michael Diffley

Journal of the Minnesota Academy of Science

The circadian quotient, briefly CQ, serves to estimate the prominence of a rhythm with a period of about 24 hours. The CQ may be computed from so-called variance spectrum analysis, among other procedures ( 1) . Computational details and some applications have been discussed earlier (1 , 2). We wish to illustrate herein the use of the CQ for gauging the development of a circadian sleep-wakefulness rhythm in the senior author's first-born child, FAR, also documented in general terms, elsewhere ( 3).

Food Intake As A Function Of Duration Of Food Deprivation In The Albino Rat, John H. Wright

Master's Theses

The present study is an attempt to investigate food intake as a function of hours of food deprivation for a wide range of deprivation values. On the basis of the existing evidence it is expected that intake will increase for the shorter deprivation values but subsequently decrease for the longer deprivation values. Additional interest lies in the secondary measures of weight loss during deprivation, water intake during the consumption period, and weight gained during the consumption period.
