Unidirectional Mazes for Studying Human Learning

The purpose of this study was to determine if academic performance affects locus of control scores. Twenty-one college students were randomly assigned to either a treatment or control group by sex. The treatment group received mnemonic training enabling them to score better than the control group. The treatment group had significantly more internal scores than the control group with the Rotter Locus of Control Scale but not with the Nowicki-Strickland I-E Scale.     

The Force/Force-Variability Relationship Under Controlled Temporal Conditions

Previously, an inverted U relationship between force and force variability was demonstrated in both static and dynamic responses. Recent research suggests that the inverted U function may be due to a lack of control of the temporal aspects of the response. To investigate this hypothesis, we examined the relationship between force and force variability in rapid movements under controlled temporal conditions. Subjects (N = 4) made rapid reversal responses with a horizontal lever (using elbow flexion and extension) such that the time to reversal (160 ms) and the distance to reversal (45°) were held constant in each of six load conditions (either 0, .260, .520, .780,1.040, or 1.560 kg added to the lever). When time to reversal and time to peak acceleration were held constant, a curvilinear relationship between force and force variability resulted, suggesting that the inverted U function is related to control of the temporal aspects of the response.     

Personality Variables in Rorschach Scoring

Twenty-three clinical trainees scored a standardized list of 150 Rorschach responses and were administered the EPPS. Ten directional hypotheses were advanced which predicted certain personality attributes of those making scoring errors in various determinant categories. Results showed significant differences between high and low error groups on scores on several EPPS scales, supporting four of the ten hypotheses. Scoring errors in the color, human movement, texture, and vista determinant categories were related to scores on the Exhibition, Affiliation, Autonomy, and Abasement scales, respectively. Implications of these results are discussed regarding the reliability of Rorschach interpretations.     

A Method for the Evaluation of Affective Associations to Figure Drawings

Usual scoring systems for figure drawing techniques are based on structural and content aspects of the drawing, and ignore the affectively toned associations that occur when an observer first sees a drawing. A system for measuring two components of judgment, (a) emission of affective associations (b) evaluation of affective associations, has been developed. This method was applied with some success in studying individuals who had represented in their drawings an image that corresponded to their actual physical appearance. The research so far suggests that the evaluation component of judgment may contribute more to discrimination than the emission component.     

Effects of A Training Program on Teacher Behavior and Handicapped Children's Self-Concepts

The purpose of this research was to assess the effectiveness of the revised Utah State University Self-Concept Protocol Program in changing teacher behaviors presumed to be related to pupil self-concept. This program was focused on teachers with handicapped pupils in mainstreamed classrooms (grades 4 through 6). Ten volunteer teachers were trained in the self-concept behaviors as part of an inservice course. Eight additional volunteer teachers served as a no-treatment control group. Program-related teacher behaviors were observed and a pupil self-concept measure was administered before and after the inservice course. Results indicated that, although no changes occurred in program-related behaviors for the control group teachers, experimental group teachers showed significant increases on six of the 12 program-related behaviors. No gains in self-concept were made by handicapped children; however, there was some evidence for differential effectiveness of the program for learning disabled and emotionally handicapped children.
