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 …

An Investigation Of Three Aspects Of Cognitive Style In Young Children, Briar D. Gaudun

Theses and Dissertations (Comprehensive)

The purpose of the present study was to investigate the developmental concept of the process of differentiation as reflected in cognitive style with three and seven year old male and female Ss. The ideas underlying this study stemmed from the Witkin concept of an analytical versus a global cognitive style. The design, however, differed considerably from the studies of Witkin, Dyk, Faterson, Goodenough, and Karp (1962) by incorporating three aspects of psychological functioning which theoretically should be highly related, although they have never been investigated simultaneously. The three aspects of psychological functioning were perceptual articulation as measured by the Preschool …

False Physiological Feedback And Acceptance Of A High Fear Message, Michael T. Gray

All Master's Theses

This paper presents an attempt to differentiate between the drive reduction and parallel response theories as explanations of results obtained in fear communication research.

Forty-eight subjects were divided into four equal groups and while listening to a high fear message, three groups received false GSR feedback. The fourth group (control) received no feedback. The results failed to differentiate between the two theoretical models and also failed to support findings of an earlier study which used similar feedback techniques.

It was concluded that further research using false feedback techniques needs to be done.

The Role Of Stimulus And Label Familiarity In Concept Learning, David W. Philips

All Master's Theses

Performance on a concept learning task was investigated by employing familiar and unfamiliar stimulus patterns, three pretraining conditions, and two conceptual rules. Subjects were given either observation or preliminary paired associate practice in labeling shapes with meaningful or nonsense labels and were then required to solve a concept learning task to criterion. It was found that tasks involving familiar stimuli were learned more rapidly than those involving unfamiliar stimuli, and that meaningful verbal pretraining for unfamiliar stimuli resulted in more rapid learning than observation or nonsense label pretraining.

Interanimal Transfer Of A Learned Response Tendency With Control For Autonomic Arousal, Landgrave Thomas Smith

All Master's Theses

In three experiments using 180 rats, extracts of brain protein were used for interanimal transfer of an avoidance response from donors to recipients. In the first experiment it was found that avoidance learning in donors produced a response transfer, but autonomic arousal did not. The second experiment confirmed these results, and demonstrated a response transfer after a single donor training trial. The third experiment confirmed the results of the first two, and the recipient response strength showed evidence of extinction and spontaneous recovery.

The Course Of Amnesia Up To Twenty-Four Hours After Non-Contingent Treatment As A Function Of The Footshock-Electroconvulsive Shock Interval, Thomas C. Whitaker

All Master's Theses

This study tested specific predictions of the state-dependency hypothesis concerning the effects of footshock (FS)-electroconvulsive shock (ECS) treatment interaction on memory storage. Rats were trained in a water "T" maze to turn either left or right. Twenty-four hours later they received FS-ECS treatment. The FS-ECS intervals were .5 sec., 10 sec., 30 sec., and sham (no FS-ECS). Testing took place either 1, 6, 12, 18, or 24 hr. after treatment. Results indicated trends, but no significant evidence of the amnesia gradient being related to the FS-ECS interval.

Failure To Find A Memory Gradient In A State Dependency Paradigm, James Harold Thomson

All Master's Theses

Rats were trained in a passive avoidance task. Twenty-four hours later they were given a noncontingent footshock (FS) followed by electroconvulsive shock (ECS). ECS followed FS by different intervals ranging from .5 to 300 seconds in different groups. Subjects were tested 24 and 96 hours after the FS-ECS treatments for retention of the avoidance response. There were no statistical differences between the groups. This finding could not be taken as evidence that FS-ECS failed to produce amnesia since no evidence of passive avoidance conditioning in trained subjects not receiving FS-ECS.

Aldo Leopold's "Land Ethic": An Ecological Extension Of Albert Schweitzer's "Reverence For Life", John Lee Weaver

Undergraduate Honors Capstone Projects

As a member of the world community, and in the process of becoming a professional ecologist, I have begun a search for a personal ecological ethic to guide my actions. Two of the paths I have taken in my search are Albert Schweitzer's Reverence for Life ethic and Aldo Leopold's Land Ethic. They are relevant because each has extended the scope of ethics beyond Homo Sapiens. Their thoughts, with similarities and dissimilarities, form herein my travels.

Effect Of D-Amphetamine, Guanethidine, Disulfiram, And Stress On Gastric Ulceration In The Rat, Thomas M. Beall

Theses and Dissertations

Albino rats were injected with various doses of d-amphetamine (.02 mg/kg- 9 mg/kg) and subjected to 4 hours restraint in a cold (+5 degrees C) environment. Differential effects on ulceration were observed as a function ot the d-amphetamine dose level. Pretreatment with a .50 mg/kg injection of d-amphetamine significantly inhibited ulceration over that of saline injected, control animals, while a 9 mg/kg dose injection of the drug significantly facilitated it. Such results were explained in terms of a model interaction between sympathetic and parasympathetic nervous system activity, and the effect that such activity has on gastric conditions conducive to ulceration. …

Validation Of A Measure Of Aggression, Jack Edward Shook

Masters Theses

The study attempted to validate a questionnaire as a method of measuring aggression resulting from frustration. The method consisted of correlating aggression measured by the questionnaire with aggression produced by an actual frustrating situation. An insult-failure technique was used to produce the frustration during the administration of a bogus aptitude test. Evaluation of the experimenter was the direct expression and measurement of aggression. A control group was used to insure validity of the frustration technique. Eighty six students participated in the study. The correlation was significant for males. The correlation was not significant for females. Males were not more aggressive …

The Effects Of Two Types Of Frontal Lesions On Reversal Learning And Activity Level In Rats, Meredith Ann Davison

University of the Pacific Theses and Dissertations

The purpose of this experiment was to compare traditional frontal pole lesions (FP) with lesions of the median dorsal nucleus projection (MDNP) described by Leonard. First, a comparison was made on the retention of spatial discrimination learning and the new learning of spatial discrimination reversals between these two groups of frontally lesioned rats. It was hypothesized that the most severe deficits in spatial reversal learning would be shown in rats receiving MDNP lesions since this area of the rat cortex appears to be homologous to the frontal cortex of higher species according to Leonard’s results. Second, activity was measured on …

Personal Freedom And The Environment As Determinants Of Interpersonally Trusting Relationships According To The Views Of Martin Buber, Carl Rogers, Frederick Perls, B.F. Skinner, And Eric Berne, Mary Anna Tuma Mcadams

University of the Pacific Theses and Dissertations

Small group interaction, as observed and evaluated by five major spokesmen of the past decade, will be the focal point of this investigation. Martin Buber, Eric Berne, Carl Rogers, B. P. Skinner, and Frederick Perls will each be examined, compared, and contrasted in terms of their views concerning human freedom, the essence of man, and man's relationship to his environment. These ideas expressed by the authors will be reviewed in terms of the possibility and potential for interpersonal trust, the manner in which trust between individuals is initiated, and those variables considered most relevant for the emergence of trust. Each …

State-Dependent Learning As A Function Of The Temporal Relationship Between Noncontingent Footshock And Electroconvulsive Shock, T. Scott Shutt

All Master's Theses

Rats were given a noncontingent footshock followed at various intervals by electroconvulsive shock. Twentyfour hours later they were trained on a non-shock passive avoidance task and tested for retention 72 hours later. When the interval between NCFS and ECS was short the animals showed an amnesia which reduced as the interval was lengthened. An interval of .5 seconds produced the most pronounced amnesia and intervals greater than 10 seconds produced virtually no amnesia. The results were consistent with a state dependent retrieval failure hypothesis.

The Electrophysiological Correlates Of Learning In The Developing Kitten, A. Derick Dalhouse

Student Work

The objectives of this experiment were (a) to study the development of classical conditioning in the kitten using light as the conditioned stimulus (CS) , shock as the unconditioned stimulus (US), and leg flexion as the conditioned response; (b) to investigate physiological correlates of learning during the development of classical conditioning such as visual evoked responses (VER), visual following (VF), electrocardiogram (EKG), and galvanic skin response (GSR); and (c) to ascertain the relationship, during development, between physiological and behavioral changes associated with conditioning.

Four kittens were exposed to two classical conditioning paradigms. Two Ss received a continuous 10 sec. light …

The Cathartic Effects Of Aggressive Responses Directed Toward An Inanimate Object, Timothy William Creston

All Master's Theses

This study was intended to test the catharsis of aggression hypothesis which in part holds that aggressive responses directed towards an inanimate object will have a tension reducing effect and result in a lowering of residual hostility.

The Degree And Time-Course Of Stress In The Patient Undergoing Cardiac Surgery, Hulda Esther Serra, Patricia Jo Yvonne Tygret

Loma Linda University Electronic Theses, Dissertations & Projects

An important nursing objective is to assist patients through stressful experiences. It has been assumed that cardiac surgery constitutes such a stress situation. For this reason, twenty-two patients undergoing cardiac surgery at Loma Linda University Hospital studied for the purpose of exploring the degree and time-course of were psychological stress.

The methodology consisted of administration of psychological tests before and after surgery; determination of urine catecholamines (UCA) before, during and after surgery; administration of a coping assessment tool before surgery, and a recall interview on the fifth day after surgery. The Multiple Affect Adjective Check List (MAACL)-Today form, and the …

Duration Of State-Dependent Learning Induced By Ncfs-Ecs, Larry Wayne Morris

All Master's Theses

This paper investigated the course of the state-dependent function induced by NCFS-ECS at 24 hr. time intervals, beginning at 24 or 48 hrs. after NCFS-ECS treatment and terminating at 120 hrs. Results of both experiments indicate a state-dependent effect lasting up to 72 hrs., was absent at the 96 hr. retention test but, apparently returned by the 120 hr. retention test. Recommendations included investigation of fixed time intervals after the 120 hr. retention test.
