Intradimensional Variability With Numbers And Alphabetical Letters In Conceptual Rules, Thomas Henry Clayton

All Master's Theses

Subjects were assigned to bidimensional rule problems that contained either 5, 10, or 15 levels of intradimensional variability. The stimuli consisted of numbers and alphabetical letters. There were no performance differences by either males or females when the number of levels within each rule was increased. There was a significant difference in performance among the three rules (disjunctive, conditional, and biconditional), however, the conditional was more difficult than the biconditional which is inconsistent with earlier research.

The Effects Of Truth Table Pretraining And Intradimensional Variability On Rule Learning And Attribute Identification Tasks, Eric S. Gebelein

All Master's Theses

Ss were required to sort geometrical patterns into positive or negative instances. According to (a) an attribute identification problem (wherein one of three conceptual rules was given: Disjunctive, Conditional, or Biconditional) or (b) Rule learning problem (wherein the two relevant attributes were given: either yellow, triangle or blue, circle). Intradimensional variability for each condition was either five, seven, or nine levels. The Rule effect was the only significant source of variance even though performance did worsen as intradimensional variability was increased.

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.

A Comparison Of Verbal And Geometric Stimuli In Concept Learning, Robert William Greenway

All Master's Theses

Subjects classified stimulus patterns into positive or negative instances of the concept according to either an attribute identification (AI) problem or a rule learning (RL) problem. Four types of stimulus materials were used: verbal stimuli (V), geometric stimuli (G), or two combinations of these modes, verbal geometric (VG) or verbal colored (VC). The only main effects that were significant were the Type of rule and Type of problem. Some interactions were obtained between these factors and the stimulus mode employed.

Experimenter Bias Effect At Varying Levels Of Motivation, Leslie Marie Slade Gray

All Master's Theses

This study examined the effects of experimenter motivation upon the experimenter bias effect on a person perception task. It was hypothesized that the experimenter bias effect would decrease as reward and threat of punishment increased.

Thirty-five experimenters were randomly assigned to five treatment groups including a control group, two reward groups, and two punishment conditions. Each experimenter administered the photo task to two subjects. The results failed to support the experimental hypotheses.

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 Relationship Of Dogmatism And Internal-External Control To Psychological Reactance, Edward J. Schau

All Master's Theses

One hundred ninety-two Introductory Psychology students volunteered for credit to complete the Rokeach Dogmatism Scale and the Rotter I/E Scale. The students were also asked to fill out a questionnaire, obstensibly from the administration, asking them to rate the favorability of the first five periods of the day on a scale of 1-100. Two weeks later 94 of the above students, serving as controls, were asked to fill out the identical questionnaire again. They were told that the previous ones had been lost. The 98 remaining students, serving as experimental subjects, received additional information. E said that he had heard …

Time Sampling Technique Applied To Counseling Practicum, William David Thomas

All Master's Theses

The analysis of interactions between individuals was developed primarily within the structure of classroom education. The historical development and refinement of educational interaction analysis was examined to set its use in the counseling situation into appropriate perspective. Many forms of interaction analysis have been used to investigate a wide range of variables. The review of the literature revealed discrepancies in the reported changes, if any, that took place in the verbal behavior of student counselors as a result of practicum training. To clarify this situation somewhat, this study attempted to observe student counselor verbal behavior change in association with practicum.

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.

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.

Sub-Aversive Response Contingent Foot Shock As A Positive Reinforcer, Robert Lea Fulwiler

All Master's Theses

Forty-eight rats were divided into 8 groups; four were maintained under normal conditions and the other four under sensory deprivation and tested at o, 3, 6, and 9 days after condition institution. The response was placing the head through a hole in the operant chamber and the stimulus (0, 1.2, 4, or 12 Vac) was contingent upon the response. Analysis ot variance disclosed significant differences (p<.01) between the deprived and the non-deprived groups at days 6 and 9; and a significant interaction between deprivation condition and time of test. No differences were shown between the stimulus intensities indicating that the stimulus did not have a reinforcing effect.

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.

A Correlation Between Self-Actualization And Communications Behavior, Joseph Whitney Alexander

University of the Pacific Theses and Dissertations

The planned, intensive group experience is the most rapidly spreading social invention of the century and, in the opinion of Carl Rogers, may be the most potent one. He recognizes such groups under varied labels such as T-groups, encounter groups, sensitivity training groups, and also as laboratories in human relations or as workshops in leadership, education, or counseling. Because of the emphasis on the fullest development of human potentials in most of these groups the theories and activities connected with them have come to be known as the Human Potential Movement.

The primary purpose of this investigation is to determine …

The Use Of Selected Films And Film Discussions In Modifying Social Distance In Elementary School Children, Stanton C. Baker

All Master's Theses

When conflicts involving interpersonal relationships arise within the school setting, it would appear appropriate to attempt to cope with these conflicts within the framework of the school; particularly the classroom. Many methods of modifying behavior through group procedures have been attempted with varying degrees of success. It was the purpose of this study to investigate the effectiveness of one such method; a fiIm-discussion technique. This program was developed to modify behaviors, attitudes and/or perceptions which interfere with the development of constructive interpersonal relationships within an elementary classroom.

Television-Mediated Aggression And Its Effects On Children’S Level Of Aggressiveness, Thomas M. Ferguson

All Master's Theses

It was hypothesized that subjects viewing film-mediated aggressive models would perform more aggressive behaviors in the test situation, than either of the other two groups, despite the low similarity factor. Results failed to confirm this hypothesis. It was found that boys were more aggressive than girls across all treatment levels.

Mmpi Characteristics Of Students Showing Conduct Infractions At Utah State University, Carl S. Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the personality characteristic as measured by the Minnesota Multiphasic personality Inventory (MMPI) was made of an experimental group of students brought before the Standards Committee at Utah State University for infractions against the school's code of conduct. It was then compared with personality characteristics of a control group representing the remaining student body.

The result was no significant difference between the two groups on any of the MMPI scales.

After checking the activities of the two groups, it was found that the experimental group was lower in grade point average than the general student body, but this …

Effects Of Nurturance On Incidental Imitative Behavior, Ronald Raymond Monti

All Master's Theses

The purpose of the present study was twofold. It was hypothesized that a prior nurturant interaction with an adult model (M) would significantly increase incidental imitation in a child subject (S) receiving this positive relationship over Ss who interacted with a non-nurturant M, or Ss who received no interaction with M. Secondly, the length of the experimental nurturant relationship was manipulated in an attempt to determine its importance in obtaining increased imitative behavior.

Use Of The Pals Test To Differentiate Between High Achieving And Low Achieving Fifth Gradestudents: A Validity Study, Mickey H. Parson

All Master's Theses

The purpose of this investigation was to determine if the PALS Tests (Williams, 1958, 1961, 1964) would significantly differentiate between low achieving and hie;h achieving 5th-grade students. The basic design was the same basic design as used by Williams (1961), except that high achieving and low achieving students were used instead of acting-out and normal children. It was intended that this research supplement existing data concerning validity of the PALS Tests. The test author (Williams 1958, 1961, 1964) seems to be the only person who has conducted research regarding the PALS.

The Effects Of Motivation Level And Task Difficulty On Performance On A Vigilance Task, Donald C. Johnston

All Master's Theses

Although many variables affecting vigilance behavior have been identified, there has not been substantial agreement on the importance of these variables as contributors either to performance decrements often found in laboratory research or to performance levels in industrial inspection tasks. Two variables of presumed importance are level of motivation and task difficulty. The purpose of the present experiment was to assess the main and interactive effects of these variables on performance on a task which approximated more closely an industrial inspection task than have the bulk of traditional vigilance studies.

A Study Of Early Reasoning Skills In The Trainable Mentally Retarded : As Related To Piaget's Seriation Theory, Robert William Ginther

University of the Pacific Theses and Dissertations

In terms of Piaget's theory of cognitive development and the relationship he attributes between reasoning and the development of classification and seriation skills, the following questions arise: can early reasoning ability be enhanced through training? If IQ tests are accepted as measures of intellectual function, do they then contain a significant number of seriation type questions? If so, will the seriation test be an accepted measure of intellectual function?

Concept Identification As A Function Of Three Semantic Dimensions, Richard Eugene Edwards

All Master's Theses

It is the purpose of the present study to determine the differential effects of the three primary semantic dimensions on the ability of Ss to solve a concept identification problem. It was hypothesized that the performance level, as measured by a criterion of learning ten successive responses containing no more than one error, time to completion, and the total number of errors, will be higher for Ss working on the evaluative dimension than for Ss working on the potency or activity dimensions. Two additional hypotheses were formulated in an attempt to answer the following questions: 1) Is the ability to …

Verbal Conditioning With Vicarious Reinforcement As Related To Peer Attitudes In Grade-School Children, Margaret Mccutcheon Lauterbach

All Master's Theses

The purpose of the present study was to determine the effects of peer attitudes toward performers in a verbal conditioning experiment using vicarious reinforcement, and to determine whether birth order or need for social approval had any effect on conditioning. Fifth grade and sixth grade students served as subjects, with performers (those to be directly reinforced) from the same grades as the observers.

The Effect Of Dominance Level When Using Mediated Generalization To Facilitate Concept Formation, Delbert Smith Mchenry

All Master's Theses

This investigation was concerned with demonstrating differences in order of concept attainment as a function of the degree of association between a concept instance and concept response, using mediated generalization.

An Experimental Analysis Of Superstitious Behavior In College Males, Nancy Alice Metzler

All Master's Theses

The possibility that superstitious responses would occur when aversive stimulation was randomly presented was investigated. There were three groups of 20 male introductory psychology students each. The Shock Group (SG) was given 45 unavoidable shocks. The Reinforcement Shock Group {RSG) was given 100 positive reinforcements and then 45 unavoidable shocks. The Reinforcement Punishment Group received 100 positive reinforcements and then 45 response contingent shocks and served to test the effectiveness of the shock as a punishing stimulus. Superstitious responses seemed to occur, but Ss of SG showed response patterns typical of punishment, while Ss of RSG showed increases in rates …

The Effects Of Positive And Negative Reinforcement On A Learning Task In Hospitalized Patients, Gary Robert Lancaster

University of the Pacific Theses and Dissertations

A number of writers have suggested that in comparison to normals, schizophrenics are less responsive to positive records or reinforcers (e.g., Hunt & Cofor, 1944) and overly sensitive to punishment or social censure as compared to normals (Fromm-Reichman 1954). Garmezy & Rodnick (1957) have proposed that schizophrenics are highly sensitive to any censure or disapproval, arising from their interpersonal contacts. They further say that such intolerable levels of anxiety are aroused that schizophrenics are held to be much more strongly motivated than normals to reduce the anxiety by acting to avoid or escape the censorious aspects of the situation.

Operantly Conditioning A Boy’S Classroom Behavior, Daniel Lee Mcivor

All Master's Theses

It was hypothesized that (a) if attending and correct responses were followed by approving attention from the staff, then the rates of attending and giving correct responses would significantly increase; (b) if yelling, rocking, and hitting were immediately followed by a command to stop, or by placement in a time-out room, then the rates of those behaviors would significantly decrease; and (c) if the above conditioning procedures were dropped, then the rates of all behaviors under study would return toward their operant levels.

Suggestibility And Its Relationship To Instructional Set In Serial Learning, Richard Walter Giroux

All Master's Theses

The purpose of this study was to attempt to determine the influence of two variables, suggestibility and instructional set, upon the individual's performance in a serial learning task. The attempt was made to find whether it is the instructional set that affects the outcome of a serial learning task or whether it is suggestibility that is the primary variable. The approach to this problem was based upon past studies in three different areas of psychological research. These were the areas of set, serial learning, and suggestibility.

The Effect Of Electroconvulsive Shock Following One-Trial Avoidance Learning In The Rat, Richard H. Lovely

All Master's Theses

It is hypothesized that (1) If rats are given electroconvulsive shock, following a footshock to condition an avoidance response, they will display initial retrograde amnesia and that this amnesia will diminish over time as manifested by recovery of the avoidance response; (2) This recovery is not a pure function of time but involves re-exposure to the original learning situation.
