The Effect Of Overlearning And The Associative Value Of The Stimuli Upon Reversal Learning, Ralph Daniel Marken

All Master's Theses

In this experiment the relevance of the associative value of the stimuli in an overlearning reversal task will be examined as well as the persistence to respond to the former positive stimulus after reversal. That is, (1) Does the associative value of the stimuli have an effect upon the occurrence of the ORE, and (2) Do human Ss who have received overlearning tend to respond to the former positive stimulus upon reversal for more trials than do subjects receiving no overlearning as has been found for animals?

Delayed Auditory Feedback And Retention Testing Time, Wayne K. Miller

All Master's Theses

There have been many studies exploring variables that contribute to the appearance of the phenomenon, but strikingly few studies attempting to relate DAF to learning. Since sensory feed back is very important to behavior and especially learning, it would seem that the DAF phenomenon could yield some significant information for learning.

The Relative Efficiency Of Auditory (Social) Reinforcement Vs. Food Reinforcement With The Squirrel Monkey (Saimiri Sciureus) In An Operant Situation, David R. Mcmurray

All Master's Theses

Research using non-deprivation and sensory or food reinforcement has received little attention to the present time. It is possible that, at least in the laboratory, sensory reinforcement under non- deprived conditions may be a much more economical and efficient reinforcer than food reinforcement under deprived conditions, which is traditionally used.

A Comparison Of Two Non-Verbal Intelligence Tests As Predictors Of Academic Success Of Navajo Students, Stanford S. Larson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was a search for a valid and reliable tool for the measurement and appraisal of the Navajo student at Intermountain School whose cultural and bilingual background make many highly verbal tests untrustworthy. The two tests chosen for the study were the Chicago Non-verbal Examination and the Cattell Institute for Personality and Ability Testing Culture Free Test. It was assumed that these tests would call attention to students who had good intellectual ability but were below standard in reading and verbal development and had been overlooked because of their lack of verbal fluency.

The two tests were administered to …

A Method For Quantifying The Effects Of Apomorphine Upon The Gnawing Syndrome Of The Rat, Paul Robinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Various methods were tried in an attempt to obtain a technique for quantifying the gnawing effects of apomorphine on rats. A technique using a restraining tube was developed.

Under a 2 milligram per kilogram intraperitoneal injection of apomorphine, four female Long Evans hooded rats were placed on continuous and fixed reinforcement schedules using a gnawable pine block. Subjects would learn to turn their heads away from the gnawable object in order to obtain 15 seconds of gnawing time. The rate of response increased from less than one response in 5 minutes to over 3 responses per minute in 10 one-half …

The Effects Of Response Set On The Structured-Objective Rorschach Test, Richard Y. Moody

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The normal forced-choice Structured-Objective Rorschach Test (SORT) and a modified free-choice SORT were administered to sixty high school students to determine the effects of response set (e.g. social desirability). The results were inconclusive. The following trends, however, were observed: (1) The free-choice modification was more resistant to response set distortion than the normal forced-choice SORT. (2) The free-choice administration showed greater flexibility in enhancement and resistance to social desirability. (3) There was little sex difference in factor scores with respect to choice administration. Females, however, gave more responses than males on the free-choice SORT.

A Comparison Of Intellectually Normal Children, Mentally Retarded Adolescents, And Mentally Retarded Adults On A Three Dimensional Concept Formation Sorting Task, James C. Kamprud

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purposes of this study were: (1) to compare nine groups of subjects composed of intellectually normal children, mentally retarded adolescents, and mentally retarded adults on a three dimensional concept formation task; (2) to determine the effects of discrimination training on the sortings of the nine groups on the experimental task.

The 207 subjects of this study were divided into nine groups. Seven of the groups, consisting of high average and low average grade 3, superior high average, and low average grade 6, and high and low adolescent retardates were chosen on the bases of school grade level (3, 6, …

Variation In The Order Of Presentation Of Cues As One Variable In Concept Organization, John E. Genasci

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the experiment, with forty-eight students as subjects, a series of nonsense syllables (DAX, MEF, TOV, VIC, YOP, ZIP, and ZIL) were to be associated with four geometric figures. The task was so arranged that Zip applied to all figures, Dax and Vic to subsets of two figures each, and the remaining were individual labels. In each of three experiments there was an experimental group that received pre-response cueing by means of an analogy which involved hierarchic concepts in the same general form, i. e ., animal, wild, tame, and individual names.

The results suggest that the order and timing …

Relationship Between Self-Concept Discrepancies And The Expression Of Need Achievement In Children, Ian Griggs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study was designed to test the hypothesis that a significant relationship exists between self-concept discrepancies and expressed need for achievement.

A self-concept discrepancy score was obtained and a low and high discrepancy group was isolated.

Expressed need for achievement was measured by the use of the Thematic Apperception Test and scored according to the Atkinson method.

Mean comparisons of need achievement scores of subjects whose discrepancies between actual and ideal self-concept were in the upper or lower one-third of the distribution were found not to be significant at the 5 percent level of confidence.

Control Of Behavior Through Reinforcement Menus, Gary Lyndle Holt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reinforcement menus were used to change response probabilities while maintaining control over two ''trainable," female, mentally retarded children.

An empirically determined reinforcement menu representing high probability behaviors, five for S₁ and four for S₂, was used in a contingency management system. Instructions were given concerning the contingencies for obtaining reinforcement. Subjects were allowed the opportunity to engage in a high probability behavior only after successful completion of fixed units of reading or arithmetic tasks. After stable performance was established, four additional menus were prepared to approximate in increasing degree, low probability behavior. Measurements were taken of task …

The Development Of A Tree Drawing Test: A Feasibility Study, Garry Lee Edwards

Theses, Dissertations and Capstones

The analysis of drawings has long been recognized as a method for investigating varied aspects of the psychology of child development. Goodenough {1926) cites studies by Cooke in 1885 and Ricci in 1387 as being the earliest accounts of interest in children's drawings. These early collections and observations were mainly descriptive in nature. They generally included such areas of investigation as single child longitudinal observations; longitudinal group observations; observations on the drawings of primitive peoples; observations on selected groups of artistically talented children; and later, observations made on groups of psychopathic subjects.

The Relationship Between Food And Fear, Henry Tjahjono

University of the Pacific Theses and Dissertations

Traditionally, the procedure of feeding an organism in a fear-producting situation has been viewed as having a fear-reducing effect, called counterconditioning. English and English define counterconditioning as the procedure of conditioning a second and conflicting response to a conditioned stimulus that is not simultaneously being reinforced. Fear is reduced by conditioning to the fear-producing stimuli the incompatible emotional responses associated with eating (e.g.--Miller, 1951)

The strength of fear was illustrated by Miller in 1951. He found that albino rats, trained to run down an alley to secure food at a distinctive place and motivated by a 46-hour hunger, would pull …

The Interaction Of Delay And Magnitude Of The Reward On Acquisition And Extinction In The Straight Alley Runway, Peter Charles Habley

University of the Pacific Theses and Dissertations

The purpose of this study is to clarify and accurately describe the interactive effects of several amounts of reward and delay on acquisition and extinction or rats in a straight runway. A factorial study involving several levels of reward and delay is presented to further describe and possibly predict what effects these independent variables have on learning curves.

The major purpose of this paper, then, is to determine the interactive effects of delay and magnitude of reward, and to present the results in a clarifying and informative manner.

Classically Conditioned Licking And Acquired Orienting As A Function Of Qualitatively Different Ucs Values : Acquisition, Shifting And Extinction, Jerry Weeks Rudy

Master's Theses

The purpose of the present study was twofold: (A) to study classically conditioned licking in rats as a function of a qualitative UCS difference, defined as 15% sucrose concentration and 0% concentration (plain tap water); (B) to study acquired orienting as a function of these UCS values. Several aspects of conditioned performance were investigated: (1) the effect of UCS intensity on level of responding during acquisition; (2) the effect of UCS intensity on rate of approach to terminal level of responding; (3) a possible learning performance distinction in appetitive classical conditioning; (4) rate of extinction as a function of the …

Pain Elicited Aggression As A Function Of Withdrawal From Morphine Addiction, Brian G. Teel

Masters Theses

One branch of aggression research has concentrated on the elicitation of aggressive behavior by means of exteroceptive stimulation. Electric shock or similar painful stimuli (Ulrich & Azrin, 1962) are well known to produce fighting in the laboratory rat. This basic method has allowed experimental analysis of a wide scope of associated variables.

Ulrich and Azrin (1962) investigated several different parameters. They found that laboratory rats increased their fighting behavior as the frequency of shocks increased from 0.1 to 38 shocks per minute. With frequency fixed, the fighting response rate resembled an inverted U-shaped curve when shock intensity was increased from …
