There have been few investigations employing the level of aspiration as a motivational independent variable. The problem of the present study was to investigate the effect of an expressed level of aspiration on a subsequent level of performance on a cancellation task and to relate this effect to socio-economic classifications.

The purpose of the present investigation was to investigate the relationship of cognitive complexity, as measured by a quantitative index of human movement responses, and the number of different constructs in one psychological system.

The purpose of this study is to investigate the relationship between personality and certain characteristics of decision-making behavior in a modified two-choice probability learning situation. More specifically, this study addresses itself to the following questions: (1) Can personality correlates of the decision-making process be demonstrated? (2) Are personality factors related to individual differences in maximizing tendency, risk-taking, and decisiveness? (3) If such relationships, exist, who do they fit into the framework of existing decision-making theory?

The purpose of the present study was to determine the effects of certain demographic factors upon attitude formation. The attitudes of Texas registered nurses toward trade unionism and their own right to strike were measured in terms of the effects of these selected factors.

The purpose of this thesis is to see if a significant change in the self concept of college students can be brought about through short term group counseling.

The purpose of this study was to investigate the relationship among the need to achieve, field independence, and grade-point average.

It was the purpose of this present study to investigate the effects of two types of music, tonic and sedative, on the gross motor activity of profound mental retardates. The primary objective was to determine if therapeutic benefits resulting from the application of music could be extended to profound retardates as has already been demonstrated with other levels of retardation.

It was the purpose of this study to investigate the nature of the relationships among anxiety, achievement, and intelligence. It was deduced that anxiety and intelligence work together mainly at the level of average intelligence. At this level, the addition of drive in the form of anxiety increases performance level, while a lack of drive or anxiety decreases that level. The influence of anxiety on academic achievement is insignificant at other levels due to the overriding effects of intelligence.

The purpose of the present study is to compare the 1959 revision of the Columbia Mental Maturity Scale (CMMS) with the Wechsler Intelligence Scale for Children (WISC) for use as a psychometric instrument for determining the mental ability of mentally retarded male children.

The present study was an attempt to measure the direction of aggression among three diverse groups, namely, policemen, narcotic-addicts and Seventh Day Adventists. The second aspect of this investigation was to determine the group conformity tendencies of the three basic groups. The Rosenzweig Picture-Frustration Study was used as the measuring instrument.

This study was conducted in order to investigate the hypothesis that the vocational rehabilitation training situation is itself therapeutic. The training situation is of course attempting to complete the final phase of rehabilitation by actually helping the handicapped individual to go out into the world again as a productive human being.

It is the intent of this study to investigate an aspect of the accuracy of first impressions and the stability of attitudes formed on the basis of these impressions. The study of first impressions and their influence on behavior is one aspect of the general topic of person perception.

One purpose of this study was to determine of the actual physical dimensions of an individual are related to the dimensions of his human figure drawings. The specific physical dimension used in this study is that of stature of height. Another purpose of this study was to determine if college males majoring in Physical Education might be superior to college males majoring in Industrial Arts in terms of their clarity of body image.

The present study deals with the application of various measures of intratest and intertest scatter to the items and subtests of the Wechsler Adult Intelligence Scale, or WAIS, in an attempt to improve the WAIS as a psychodiagnostic indicator of schizophrenia.

The study is an attempt to measure psychopathic tendencies in the girl who becomes pregnant out of wedlock compared with the average non-pregnant college co-ed. This characteristic, when evidenced in a subject's personality, may be reflected in a High T score on the Pd scale of the 1MPI.

The problem with which this investigation was concerned was to determine whether or not fear of death was related to positive future time perspective and self-esteem.

The problem of this research may be stated as a study of the relationship between successful weight reduction on the part of people involved in a group program, and the two variables of ego strength and social participation.

The purposes of the present study are to try to establish whether perception and motor skill are determinant factors of performance on the Bender-Gestalt Test and to investigate the degree of relationship and importance of each factor on the B-G-T.

The purpose of this study is to investigate, empirically, the response of the severely mentally retarded to different types of music, tonic and sedative, as well as responses during "quiet" periods.

The purpose of the present study was to further investigate the effects of frustration on the reward value of a goal object. Under the assumption that animals will learn to take the shortest path to a goal and that the reward value of an object will increase as effort increases, the following hypothesis was proposed: If rats are frustrated in the short path of a single choice maze (experimental group) then the experimental group's running time for the long path will be less than that of a control group not frustrated in the short path.

The problem of this study was to determine the relationship between the nature of an individual's self-concept and belief system to his orientation toward internal versus external control of reinforcement. This study was designed to investigate the relationship of two variables, self-concept and open versus closed belief system, to a third variable, locus of control.

Since much of the existing research which points to the low validity of the Draw-a-Person technique has used differentiation of diagnostic categories as a criterion, this study will be restricted to a consideration of the Draw-a-Person technique as a means for discriminating between a group of individuals who manifest conflicts in the area of sexual adjustment and a control group which does not show these conflicts in any appreciable amount.

The present study is an attempt to determine which of several different types of reinforcers is most effective in discrimination learning using institutionalized mentally retarded boys of different intellectual levels as subjects. If one type of reinforcement works more effectively in conditioning one level of institutionalized mentally retarded subject, then that type of reinforcement could be used to greater advantage in controlling behavior than some other, less effective kind of reinforcer.

It has not yet been demonstrated that music can be used therapeutically with profoundly retarded children. One way these children might be helped to respond to music, and therapeutically benefit from it, would be to use operant conditioning in an effort to enhance gross motor activity and then progressively shape responses until more complex behavior patterns are formed. Once these children can respond motorically in the presence of musical stimuli, continuation of responding may be possible by pairing motor activity with musical stimuli. This experiment investigated the effects of operant conditioning and music on the motor activity of profoundly retarded children in an effort to determine the therapeutic usefulness of music with such children.
