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 …

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, …
