Beyond the high point code in testing Holland's theory

This study was designed to test and expand Holland's vocational development theory by utilizing more than a single high point code in classification of personality patterns of jobs. Significant positive results were obtained to support Holland's premise that people search out environments and, hence, vocations that are compatible with their personalities. A more “refined” and/or “subtle” difference was shown in the personality-job relationships when two high point codes were used.     

Semantic organization in deaf and hearing subjects

Hierarchical cluster analysis of data from the sorting of noun words was used to compare semantic structures in 63 profoundly deaf and 63 hearing adolescents. In the first study, performance differed only for a set of words referring to sounds, where deaf persons have no experience, and not for a set of common noun words and pictures. In the second study, differences between matched sets of high- and low-imagery words were comparable for 63 deaf and 63 hearing subjects. It is concluded that deaf subjects manifested abstract hierarchical relations and were not dependent on visual mediators or hindered by the absence of acoustic mediators.This investigation was supported in part by National Institutes of Health Research Grant NS-09590-03 from the National Institute of Neurological Diseases and Stroke and in part by a Faculty Research Grant from Bowling Green State University.Portions of Study 1 were previously reported at the Eighty-first Annual Convention of the American Psychological Association, Montreal, 1973.     

A self-administered program for public speaking anxiety.

Therapist-administered desensitization was compared with a take-home manual for self-administering desensitization, where the self-administering subjects had varying degrees of contact with therapists. These treatments were compared with an attention-placebo procedure and no-treatment controls. None of the treatment procedures had any effect on behavioural manifestations of anxiety in public-speaking phobics, but all treatment subjects showed greater reductions in subjective anxiety than either of the control groups. The drop-out rate was greatest for the no-contact manual group indicating the value of brief supervision in its use. The implications of the failure to change overt behaviour in view of Paul's (1966) earlier findings, are discussed.     

Skills training and self-administered desensitization in the reduction of public speaking anxiety.

The aim is to test the following hypotheses. Since desensitization targets only “feelings” of anxiety, and skills training targets only overt behaviors, the predictions based on the earlier findings (Marshall, Presse and Andrews, 1976; Paul, 1966) are as follows: (a) the combination of skills training and desensitization will be more effective than desensitization alone, but no more effective than skills training alone, in reducing behavioral manifestations of anxiety; (b) the combination will be more effective than skills training alone, but no more effective than desensitization alone, in reducing subjective distress; (c) skills training will be more effective than desensitization in reducing behavioral manifestations of anxiety; and (d) desensitization will be more effective than skills training in reducing subjective distress.     

Induction of Relational Schemas: Common Processes in Reasoning and Complex Learning

Five experiments were performed to test whether participants induced a coherent representation of the structure of a task, called a relational schema, from specific instances. Properties of a relational schema include: An explicit symbol for a relation, a binding that preserves the truth of a relation, potential for higher-order relations, omnidirectional access, potential for transfer between isomorphs, and ability to predict unseen items in isomorphic problems. However relational schemas are not necessarily coded in abstract form. Predictions from relational schema theory were contrasted with predictions from configural learning and other nonstructural theories in five experiments in which participants were taught a structure comprised of a set of initial-state,operator → end-state instances. The initial-state,operator pairs were presented and participants had to predict the correct end-state. Induction of a relational schema was achieved efficiently by adult participants as indicated by ability to predict items of a new isomorphic problem. The relational schemas induced showed the omnidirectional access property, there was efficient transfer to isomorphs, and structural coherence had a powerful effect on learning. The “learning to learn” effect traditionally associated with the learning set literature was observed, and the long-standing enigma of learning set acquisition is explained by a model composed of relational schema induction and structure mapping. Performance was better after reversal of operators than after shift to an alternate structure, even though the latter entailed more overlap with previously learned tasks in terms of the number of configural associations that were preserved. An explanation for the reversal shift phenomenon in terms of induction and mapping of a relational schema is proposed. The five experiments provided evidence supporting predictions from relational schema theory, and no evidence was found for configural or nonstructural learning theories.     

Fatalism as a barrier to cancer screening among African-Americans: Philosophical perspectives

Fatalism has been identified as a crucial barrier to participation in cancer screening among African Americans. The essence of fatalism is woven throughout the lived experience for some African Americans. Therefore, to fully understand its impact, fatalism must be viewed within its broadest historical and sociocultural context. This article explores the philosophical origins and the practical significance of fatalism with regard to cancer screening among this population. Health care professionals must position themselves to promptly identify fatalistic persons. Interventions to successfully negate the influence of fatalism are needed.     

Visual form discrimination: Multidimensional analyses

Nonmetric multidimensional scaling techniques were used to evaluate discrimination latency as a similarity measure. A three dimensional Euclidian solution was found for a sample of random polygons. The dimensions were labeled compactness, jaggedness, and elongation. The spatial configuration was highly similar to results obtained from similarity estimates and the dimensions were systematically related to physical shape measures.     

Effects of moderating variables on product managers' behavior

This study examined the moderating effects of role autonomy, need for affiliation, and tolerance of ambiguity on the relationships between role pressures of conflict and ambiguity and personal outcomes of job satisfaction, job-related tension, and perceived performance. Data from 166 product managers indicate that role autonomy and need for affiliation do have moderating effects unlike tolerance of ambiguity. Managerial implications are discussed.
