Physical Fatigue As A Discriminative Cue In Choice Learning In The T-Maze, Robert L. Detty

Theses, Dissertations and Capstones

It has been found that animals which have acquired a response while under the influence of a drug , fail to emit this response when subsequently tested while nondruggedo Likewise, animals which have acquired a response while nondrugged fail to emit this response when subsequently drugged. However, under both conditions, Ss emlt the response when retested in the original condition. either drugged or nondrugged. Thus, the presence of the response appears to be conditional upon the drug state of the organism during acquisition. This phenomenon has been called state dependent (StD) or dissociative learning (Overton, 1964). Dissociation apparently varies along …

Influence Of Behaviour Setting And Interaction On Patterns Of Successful Aging, George D. Macdonald

Theses and Dissertations (Comprehensive)

This study investigated the effects of behaviour setting and interaction on patterns of engagement and disengagement within a home for the aged. The purpose of the study was to illustrate that both patterns may be a function of situational and psychological factors and therefore should not be used as definitions of “successful aging.” Data were collected using an observational technique. Observations were made on five behaviour settings for a typical week. The results indicate that there is a relationship between patterns and the two factors specified. A similar finding was reported for staff patterns within the home. Implications of these …

Towards An Understanding Of Courage: An Exploratory Analysis Of Changing Definitional Conceptions, Gertrud Lavalley

Theses and Dissertations (Comprehensive)

The present paper was an exploratory attempt at examining changing definitional conceptions of courage. Traditional conceptions were found to abound in popular definitions and confusion with respect to both the meaning and origin of courage. Unconscious conformity to societal norms, symbolic attachment to national roles, a learning theory analogue and the broad conception of S-R (stimulus-response) behaviour were examined as possible explanatory frameworks. An analysis of courage and survival clarified the relationship between courage and hope. An interdependent rather than independent relationship between the two concepts was postulated. The S-O-R (stimulus-organism-response) model was employed as a general explanatory framework for …

Genetic And Ontogenetic Variation In Response To Scopolamine And D-Amphetamine In Three Strains Of Mice, Gary Remington

Theses and Dissertations (Comprehensive)

Highly inbred mice of three strains (A/J, DBA/2J and C57BL/6J) were tested in an acitivity task at 14, 21, or 28 days of age. Ten minutes prior to testing, mice received treatment of either saline, scopolamine (0.1 or 1.0 mg/kg) or d-amphetamine (0.5, 1.0 or 5.0 mg/kg). At 14 days of age DBA mice exhibited higher levels of activity than either A or C57 mice. However, the increase in activity in C57 was such that at 21 and 28 days no difference was observed relative to DBA mice, and activity was higher than that of A mice. With respect to …

A Comparison On The State Dependent Effects Of Electroconvulsive Shock And Physostigmine On A Choice Task, Candace Susanne Brown

All Master's Theses

Two experiments compared the state-dependent effects of electroconvulsive shock (ECS) and physostigmine relative to a normal state (saline or no injection). Rats were trained in a water T maze using a discrimination-training paradigm. In Experiment 1, discrimination was found between the ECS- and normal state. However, response control was strongest in the ECS-0 treatment-training order and on non-ECS training sessions. In Experiment 2, dissociation also occurred but was more pronounced in the P-0 (physostigmine-saline) treatment-training order and on the saline training sessions. Results from both experiments indicate learning is most rapid in the treatment-no treatment training order and that a …

The Effect Of Environmental Enrichment On Delayed Alternation, Passive Avoidance And Exploration Behavior, David L. Knobel

All Master's Theses

Long Evans Hooded rats were reared in either perceptually complex (EC) or simple (IC) environments. As adults, exploration, delated alternation and passive avoidance task performance was investigated. The exploration level of the EC and IC reared groups was identical on Day 1, but on subsequent days the IC rats on delayed alternation and passive avoidance tasks was not found, but the alternation response was acquired with significantly fewer trials by EC rats.

Spatial Orientation Of Children In Dyads With Female Adults, Susan Menig Karstetter

All Master's Theses

Subjects were requested to enter the experimental setting, choose a chair, and sit while speaking to an adult female who listened to the child for two minutes. The distance and angle of seating were measured and studied with regard to the age, sex, grade level, height, handedness, academic achievement, size of chair used, and the listener.

The results indicated that seating distance was influenced by the sex, age and height of the subject and size of chair chosen. The angle of seating chosen was influenced by the sex and height of the subject and the size of chair chosen. It …

The Generalizability Of Learned Helplessness, Ian J. Grabenhorst

All Master's Theses

While it has been experimentally demonstrated that "learned helplessness" can be conditioned in a number of species, the subjects commonly employed have been dogs. This paper presents an attempt to investigate "learned helplessness" in rats (a variant of the Long-Evans strain), and examine the question of its generalizability from shock as an aversive stimulus to noise. It also explores the possible generality of "helplessness" to exploratory behavior in an open field. The results demonstrated that the Ss were susceptible to "helplessness" conditioning across shock conditions; however, "helplessness" did not generalize across shock to noise conditions. The present study also showed …

The Effects Of N-Length And Iti On Resistance To Extinction In A Free-Operant Situation, Raymond Kenworthy Mulhern Jr.

University of the Pacific Theses and Dissertations

The prediction of Capaldi's sequential learning theory (i966, 1967, 1970) that resistance to extinction (Rn) increases as a function of the number of successive nonrewarded trials (N-length) conditioned to the instrumental response has recently been supported in a discrete-trials leverpress situation but not in a free-operant leverpress situation (Wolach & Ferraro, 1971). To investigate this discrepancy, 32 male albino rats were trained to leverpress in the presence of a visual s^D under one of two N-length conditions (8 or 16) and one of four intertrial interval (ITI) conditions (5, 10, 15, or 30 sec.), the lowest of which corresponded …

Facilitation Of Retrieval Of Words From Long Term Memory, Edward John Federman

University of the Pacific Theses and Dissertations

This paper investigated whether retrieval may be facilitated by a process in which one learns to retrieve in a manner analogous to learning to learn as demonstrated by both Harlow's (1965) work with monkeys and Postman's and Keppel's (1966; Keppel, Postman, & Zavortnik, 1968) work in verbal recall. While the major focus of this study was to demonstrate this phenomenon, and the analogies cited suggest that the process will remain unspecified, an attempt was made to indicate and analyze the processes involved in the facilitation.

The Effects Of Metrazol On Acquisition Of An Oddity Task In Squirrel Monkeys, Stephen Wilson

Masters Theses

Recent evidence indicates that Metrazol can enhance learning in rodents provided certain variables such as genetic strain, difficulty of problem to be learned, and dosage levels are considered and carefully controlled. The effects of Metrazol on oddity acquisition in four squirrel monkeys was investigated. The apparatus employed was a modified version of the Wisconsin General Testing Apparatus. The dosage level of Metrazol was 15 mg/kg of body weight. The results suggest that Metrazol had no effect on the learning of the oddity task by the squirrel monkeys.

The Effects Of Reward Magnitude Following Nonreward And Punishment, John Santoso

University of the Pacific Theses and Dissertations

Four groups of 12 rats each received constant medium size rewards of nine 45 mg Noyes pellets prior to nonrewarded (N) and nonrewarded punishment (P) (0.25 rna shock of 0.1 sec duration) trials and either large (L) size rewards of sixteen 45 mg pellets· or small (S) size rewards of two 45 mg pellets following N and P trials in a runway. Following acquisition each of the four groups was randomly subdivided into either continuous N or continuous P extinction conditions. This resulted in a two X two X two completely randomized factorial design with the variables and its levels …

A Multivariate Analysis Of The Factors Affecting Treatment In A Child Guidance Centre, Brian Charles Regan

Theses and Dissertations (Comprehensive)

Initially, all the children who had received treatment and been discharged from the West End Créche between 1962 and 1971 were selected for this study. These children were then sub-divided into groups according to where they had gone after discharge. This study considered only two of these groups, 32 children who went into the normal school system and 20 children who entered institutions after being discharged. Both groups were then examined with reference to a list of forty-two variables which provided information on the children’s background and the facilities of the treatment centre. An analysis of these variables demonstrated that …

The Protestant Ethic Effect: A Multiple Dependent Variable Analysis, Ronald Stephens

Masters Theses & Specialist Projects

When an organism is allowed to choose "between working for food or receiving "free" food, what will its decision "be? For years such a question would have been addressed within the framework proposed by Clark Hull (1943): the organism would choose the alternative requiring the least amount of effort and eat the free food. However, several recent investigations have cast doubt on the generality of this lav: of least effort. Typically these studies have involved training organisms to respond for a reinforcer, defined as a stimulus that increases the probability of a response (Hilgard ?z Bower, 1966), and subsequently allowing …

Differential Assessment Of Retrograde Amnesia Produced By Hypothermia Following One-Trial Avoidance Conditioning, Duane E. Brookhart

Master's Theses

Two different measures of the retention of avoidance conditioning, frequently used in the investigation of retrograde anmesia (RA), were examined. Rats were given a single training trial on either passive or active avoidance in a conventional black-white discrimination apparatus and step-through latencies were recorded. Task sequence, footshock and hypothermia were experimentally varied across eight groups of subjects. Each S was returned to the experimental apparatus 24 hours after training and given retention tests on both passive and active avoidance tasks. Test trial latencies failed to demonstrate any retention deficits attributable to RA, and both passive and active avoidance test latencies …

The Effects Of Emotionally Important Stimuli On Dissociated Learning In A Discrimination Paradigm, Stanley P. Scoville

Electronic Theses & Dissertations

Rats were trained to turn in one direction in a modified T-maze while in one drug state and in the opposite direction while in another drug state. Incorrect turns during training were punished with shock and for three of the transfer groups, shock was contiguously conditioned to a 10 KHz buzzer in the drug state and to a 1 KHz buzzer in the non-drug state. During no-shock testing, the dissociation subjects were tested for state-dependency while the transfer subjects were tested for transfer by reversing the buzzer previously associated with the particular drug state in training. The hypothesis, that the …

Anticholinesterase Action And Electroconvulsive Shock-Induced Disruption Of Taste-Illness Association, Terry J. Debriere

Electronic Theses & Dissertations

Electroconvulsive shock (ECS) interpolated temporally between the pairing of a novel taste and an induced gustatory illness prevents the taste from being associated with the illness (Kral, 1971). Physostigmine has been shown to protect against retrograde amnesic effects of ECS on learning of a passive avoidance task (Davis, Thomas, and Adams, 1971). Physostigmine protection of ECS induced disruption of a conditioned taste aversion was investigated using a 2 (physostigmine vs. saline) x 2 (ECS vs. sham shock) x 2 (conditioned vs. nonconditioned) x 2 (conditioning day vs. test day) factorial design with repeated measures over the last factor. Results indicated …
