THE EFFECTS OF COMMUNICATION APPREHENSION ON COMMUNICATION EFFECTIVENESS1

This study investigated the following hypothesis: physiological, psychological, and verbal behavior indices of communication apprehension can predict comprehension, perception of speaker credibility, and ratings of speech effectiveness. The stimulus materials were videotapes of the first minute of 85 different students expressing their views on women's liberation. Measurement on all the indices of communication apprehension had been taken on these students as the videotapes were being prepared. Each of these one-minute videotapes was shown to a single receiver who then filled out forms measuring comprehension, perception of source credibility, and rating of speech effectiveness. Results supported the hypothesis that the indices of communication apprehension could predict all the communication effects save one, perception of character. The strongest relationship between the set of communication apprehension variables and the set of communication effectiveness variables indicated that individuals who reported high apprehension experienced much silence in their speech and received low ratings on language facility, vocal characteristics, and general effectiveness.     

THE EFFECTS OF COMMUNICATION APPREHENSION ON INTERPERSONAL ATTRACTION

Two studies are reported which indicate that high communication apprehensives are perceived as less interpersonally attractive than low communication apprehensives by members of the opposite sex. Effects of physical appearance and attitude similarity on interpersonal attraction, consistent with previous research, were also observed. It was also found that, in general, the more communication apprehensive the subject the less the subject was attracted to other people.     

STUDIES OF THE RELATIONSHIP BETWEEN COMMUNICATION APPREHENSION AND SELF-ESTEEM

This paper reports research conducted as a part of a continuing program designed to provide empirical delineation of the communication apprehension construct. Five studies are reported which indicate a substantial correlation (r =?.52 to r =?.72) between oral communication apprehension and self-esteem. Results from two college student samples (N = 192 and N = 272), two samples of elementary and secondary teachers (N = 202, N = 384), and a sample of federal employees (N = 211) indicate highly consistent relationships across age groups and occupational types.     

PSYCHOLOGICAL SEX TYPE AND ANDROGYNY IN THE STUDY OF COMMUNICATION VARIABLES: SELF-DISCLOSURE AND COMMUNICATION APPREHENSION

This study extended the investigation of gender differences in two communication variables, self-disclosure and communication apprehension, by shifting the conceptual focus from the biological sex dichotomy to the more discriminating psychological sex-role designations: masculine, feminine, and androgynous. Using the Bern Sex-Role Inventory (BSRI) as a measure of psychological sex type, the study showed that psychological sex type is superior to biological sex categories in identifying patterns of self-reported self-disclosure and communication apprehension. A number of hypotheses were considered with regard to total disclosure to same-sex friend or opposite-sex friend, and communication apprehension.     

THE RELATIONSHIP BETWEEN COMMUNICATION APPREHENSION AND ACADEMIC ACHIEVEMENT AMONG COLLEGE STUDENTS

A series of studies are reported which indicate that high communication apprehensives have lower academic achievement in traditional interaction-oriented educational systems than low communication apprehensives, but that no similar relationship exists in a communication-restricted educational system. Data are also reported indicating that high communication apprehensives prefer mass lecture classes over small classes while moderate and low communication apprehensives' preferences are the reverse. The implications of these results for choosing or designing instructional systems are discussed.     

COMMUNICATION APPREHENSION AND ACHIEVEMENT IN A PERFORMANCE-ORIENTED BASIC COMMUNICATION COURSE

The study of communication apprehension (CA) impact in the instructional environment is extended through examination of all three CA levels relative to various performance situations in a basic communication course. Results indicate significant differences in achievement indices between all three CA groups on final course grade and the first two of four performance assignments. Moderate and high CA groups were not significantly different from each other on the third and fourth performance tasks. Low and high CA groups were significantly different in all performance areas. No differences were indicated between CA groups on the final examination. Results are discussed relative to the naturalistic nature of the study.     

AN ASSIMILATION THEORY PERSPECTIVE OF COMMUNICATION APPREHENSION

In this study, both the dynamic and stable qualities of communication apprehension are examined from an assimilation theory perspective. Based upon assimilation theory, PRC A scores obtained after an intervening speech performance are predicted from initial levels of communication apprehension and discrepancies between those initial levels and the levels of state anxiety experienced during speech performance. The results of multiple regression analysis indicate that both initial apprehension levels and the discrepancy variable contributed significantly to the prediction of post-intervention PRCA scores, a finding that supports an assimilation theory perspective of communication apprehension.

THE RELATIONSHIP BETWEEN TRAIT AND STATE COMMUNICATION APPREHENSION AND INTERPERSONAL PERCEPTIONS DURING ACQUAINTANCE STAGES

The primary purpose of the research was to examine the effect of trait and state communication apprehension on interpersonal perceptions (credibility, attraction, and opinion leadership) during initial and later acquaintance stages of dyadic linkages. The results of the investigation indicated that the results of previously reported simulated studies may not generalize to real, interacting dyads. Trait CA was found to account for little variance in interpersonal perceptions. However, state CA was found to be a potent predictor of such perceptions, particularly in a later stage of acquaintance. It was found that trait and state CA were significantly correlated in the early acquaintance stage, but were unrelated at a later stage. It was also found that state CA did not decline as a function of length of acquaintance, nor did interpersonal perceptions become more positive as a function of increased interaction.     

TRUST AND THE COMMUNICATION OF PERFORMANCE APPRAISAL INFORMATION: THE EFFECT OF FEEDBACK ON PERFORMANCE AND JOB SATISFACTION

The feedback of performance appraisal information is a critical communication activity in organizations. Research on the topic, however, has generally been limited to (1) treating feedback as an undifferentiated construct, and (2) not examining the important moderating impact of trust of the receiver in the sender. Using a sample of 100 managers, this study explores the dimensionality of the feedback construct, the relationships of feedback to individual performance and satisfaction, and the moderating effects of trust on these associations. Results indicate that various aspects of feedback are differentially related to performance and satisfaction under conditions of high and low trut. Importantly, the communication of performance appraisal information is found to be a more important correlate of satisfaction and performance for subordinates who express low trust in their superiors.     

AN EMPIRICAL APPRAISAL OF THE PRCA FOR MEASURING ORAL COMMUNICATION APPREHENSION

Since 1970 about 80% of the research on oral communication apprehension has used one of two versions of McCroskey's Personal Report of Communication Apprehension. The original 20-item PRCA was introduced for the purpose of measuring apprehension beyond the traditional public speaking context. Although the PRCA-20 is reliable, some serious criticism of it has centered on its ability to tap interpersonal behavior outcomes. In an attempt to bolster its interpersonal applicability, five “interpersonally-oriented” items were added to form the PRCA-25. The studies reported herein demonstrate that both versions fail to possess sufficient reliable variance to be applicable to contexts other than public settings. In addition, it was found that the interpersonal items are a separate component of the PRCA, and as such, do not justify being treated equal in terms of additivity and, therefore, reduce the construct integrity of the PRCA.     

PERSONALITY CORRELATES OF COMMUNICATION APPREHENSION: A RESEARCH NOTE

Research is reported indicating significant relationships between communication apprehension and 18 of 21 personality variables studied. High communication apprehension was found to be associated with a wide range of socially maladaptive personality characteristics.     

THE INFLUENCE OF MOTHER-DAUGHTER RELATIONSHIPS ON WOMEN'S SENSE OF SELF AND CURRENT ROLE CHOICES

This study investigates the relationship of women's current role choices, role satisfaction, and self-esteem to their perceptions of the earlier relationship with their mothers and to their perceptions of their mothers' role choices and role satisfaction. Sixty-seven married women with preschool children were interviewed and completed self-report inventories. Results indicated that the women's primary role decisions of career, non-career work, or homemaking did not parallel those of their mothers but was related to their mothers' messages to them. In addition, career women and women at home reported having more choice in their decisions than did non-career working women. Women's self-esteem and role satisfaction were significantly enhanced ( p <.05) when the relationship with the mother was perceived as loving and accepting, with low hostility and low psychological control. In contrast, women's self-esteem and role satisfaction were generally unrelated to the retrospective reports of the mothers' roles and role satisfaction.     

COMMUNICATION APPREHENSION AND BEHAVIOR: APPLYING A MULTIPLE ACT CRITERIA1

Operating from a model derived from research on the attitude-behavior relationship, a conceptualization is presented which indicts current attempts to select a specific behavior and examine its relationship with a personality characteristic relevant to the field of communication. Evidence is presented demonstrating that the characteristic should predict well a multiple act criteria but not a single act criterion. In addition, an empirical distinction is predicted between apprehension and attitude and a comparison is made between three self-report measures of apprehension.     

THE EFFECT OF GAMING ON ATTENDANCE AND ATTITUDE

Gaining, as an approach to reducing absenteeism and tardiness, has been used successfully by a number of firms. Our research has shown that the impact of gaming on these two areas may be minimal. However, statistically significant improvement in employee attitude and cooperation has resulted when gaming was used as a vehicle for employee communication.     

EXPLICATION AND TEST OF A COGNITIVE MODEL OF COMMUNICATION APPREHENSION: A NEW LOOK AT AN OLD CONSTRUCT

A cognitive model of the processes underlying the arousal of a state of communication apprehension is proposed. This model draws upon current work in cognitive science to specify the nature of the relevant structures and the nature of the processes that operate over those structures. An empirical test of the model indicates strong support in that the interaction of long-term memory contents and perceived evaluative ness of the situation was a significant predictor of anxiety. Additionally, the model allowed the prediction of changes in physiological arousal (heart rate) over time that closely paralleled observed heart rate.

THE EFFECT OF TELEVISION AND RADIO ON CHILDREN'S CREATIVITY

The literature on creativity posits that creative abilities are stable and relatively impervious to short-term interventions. Several studies have, however, reported differential effects of media on children's imaginative play and thinking. The results of these studies are difficult to interpret owing to their reliance on nonstandardized measures of creativity. The present study examines the relative effects of television versus radio on children's creativity. Third and sixth graders were presented a story on television or radio and were then given an adapted version of the “Just Suppose” test of divergent thinking developed by Torrance (1974). Responses were scored in terms of ideational fluency, flexibility, and originality. The results indicated that the two media did not have a differential effect on children's creativity.
