Relational Communication in Computer-Mediated Interaction Revisited: A Comparison of Participant–Observer Perspectives

Studies of online environments estimate that the majority of members in online forums do not contribute to ongoing discussions and only observe or “lurk” (e.g., Nonnecke & Preece, 2000). Despite the prevalence of this form of information acquisition, direct comparisons between the experiences of these “observers” (or “lurkers”) and active participants are lacking. The present research draws on previous research examining perceptual differences between participants and observers as well as social information processing theory (Walther, 1992) and reports on three studies examining such differences in computer-mediated communication (CMC). Study 1 examined the effects in the context of interpersonal interaction in synchronous CMC. Study 2 examined the effects in the context of group interaction in both synchronous and asynchronous CMC. Study 3 replicated and extended the results of the previous studies across two time periods. The overall results (a) support the presence of participant–observer differences in CMC, (b) show that the presence of anticipated future interaction moderates said differences, and (c) provide mixed evidence that participant and observer interpretations of relational messages converge over time.     

Contradictions and Praxis Contextualized by Wartime Deployment: Wives' Perspectives Revealed through Relational Dialectics

With the continued US military presence throughout the world, it is important to understand the struggles of family members left behind during war, because they are important to the “success” of military marriages and potentially deployments. We asked 50 Army wives to discuss their experiences before, during, and after their husbands’ most recent deployment. Using relational dialectics as the theoretical framework for understanding marriage and deployment, we identified three contradictions (uncertainty–certainty during predeployment, autonomy–connection during the deployment, and openness–closedness during reunion) and several praxis patterns within them, some of which reflect potentially problematic dynamics for these military partners.     

Family communication patterns,sex of subject,and communication competence

Two hundred ninety‐nine subjects completed the Revised Family Communication Patterns instrument (Ritchie & Fitzpatrick, ) and the Interpersonal Competence Questionnaire (ICQ; Buhrmester, Furman, Wittenberg, & Reis, ). Results indicate that both family communication patterns and sex of subject influence the ability to enact certain communication skills in both same‐sex friendships and romantic partnerships. Those growing up in a strong conversation‐oriented family are more likely to report the ability to enact a greater number of interpersonal skills in both types of relationships. Women were more likely to report the ability to self‐disclose in a same‐sex friendship; however, a family communication environment that stresses a lower conversation orientation (consensual) diminishes the likelihood of acquiring that skill for women. Women were also more likely to report being able to offer emotional support in both same‐sex friendships and romantic partnerships. Men were more likely to report being able to assert themselves negatively in a same‐sex friendship, and to self‐disclose and manage conflict in a romantic partnership. Additionally, this study found that men and women employ different communication skills depending on the sex of their relational partner. Implications and future research directions are discussed.     

Maltreatment type and behaviors: Does listening matter?

This article presents an exploratory assessment of whether children's perceptions of caseworker support (e.g. feeling listened to) moderates the relationship between the type of maltreatment and problematic behaviors. Relying on data collected for the National Survey of Child and Adolescent Well-Being (NSCAW I), this research measures how often children felt listened to by their caseworkers and the effect on the relationship between two types of maltreatment (e.g. physical abuse and neglect) and problematic child behaviors. Results indicate that whereas children reported feeling listened to most of the time, there are significant differences in the probabilities of problematic behavior scores between physically abused and neglected children according to how often they felt listened to. With the exception of those children who felt listened to all of the time, physically abused children have a higher probability of problematic behaviors than neglected children. Comparisons between the two maltreatment types indicate a greater impact of listening on physically abused children across the continuum of feeling listened to (e.g. never to all of the time), than for neglected children, except for at the highest level of listening, as results indicate a small, but significant difference indicating neglected children are more positively impacted by listening than physically abused kids. Implications for practice are that children's perceptions of support from caseworkers may influence behavioral outcomes differently according to maltreatment type. Additionally, these findings encourage the inclusion of children's perspectives regarding the relationships they have with caseworkers.     

Evaluation fidelity: An examination of criterion‐based assessment and rater training in the speech communication classroom

The purpose of this study was to further investigate the effectiveness of speech evaluation procedures and measures. Specifically, this study examines the relationship between rater training and evaluation fidelity— a concept which focuses on the shared understanding of meaning between speech raters and students in terms of what is expected and what is performed. To do so, two studies were conducted. Study one hypothesized that evaluation fidelity would be associated with rater training such that inter‐rater (instructor‐instructor) reliability would be higher after training. The findings suggest that participants in Study one increased their evaluation fidelity in terms of total scores. The variance and frequency reports confirmed that the range of scores decreased (higher evaluation fidelity) after training. Study two hypothesized that instructors who provided their students with training in using the “Criteria for Evaluating Speeches” form would achieve higher evaluation fidelity than those instructors who do not. Results support this hypothesis and reveal higher evaluation fidelity between instructors and students in the group where students received a copy and explanation of the criterion‐based assessment tool.     

Relational Maintenance and the Influence of Commitment in Online and Offline Relationships

The study of relational-maintenance behaviors has sometimes included the impact of medium as a peripheral variable, but rarely has the impact of medium been tested directly. Participants (N = 1336) delineated themselves into four separate groups depending on the initial and continued use of mediated communication. They reported their use of relational-maintenance behaviors, as well as feelings of commitment towards the relationship. The medium had an impact on the use of relational-maintenance behaviors, primarily between people who had only met their partners in a mediated environment and those who had met them face-to-face. However, commitment level appears to strongly moderate the relationship between group and use of maintenance behaviors.     

Feeling Valued Matters: An Examination of Instructor Confirmation and Instructional Dissent

This study explored the relationship between effective instructor behavior—instructor confirmation—and a potentially negative student behavior—instructional dissent. Previous studies demonstrate that student characteristics provide a limited explanation for how students express dissent (e.g., Goodboy & Myers, 2012 Goodboy, A. K. & Myers, S. A. (2012). Brief report: Instructional dissent as an expression of students’ verbal aggressiveness and argumentativeness traits. Communication Education, 61, 448–458. doi:10.1080/03634523.2012.699635[Taylor & Francis Online] , [Google Scholar]). Thus, scholars have begun to investigate the influence of instructor behaviors along with student characteristics to understand why students express dissent (LaBelle, Martin, & Weber, 2013 LaBelle, S., Martin, M. M. & Weber, K. (2013). Instructional dissent in the college classroom: Using the instructional beliefs model as a framework. Communication Education, 62, 169–190. doi:10.1080/03634523.2012.759243[Taylor & Francis Online] , [Google Scholar]). This study revealed that instructor confirmation negatively related to expressive and vengeful dissent, but not rhetorical dissent. Further, the three dimensions of instructor confirmation functioned differently in accounting for variance in expressive and vengeful dissent. Future research should build towards a model of instructional dissent model that reflects the unique characteristics of the instructional context and modifiable instructor behaviors.     

Playing With Dialectics: Black Female Friendship Groups as a Homeplace

Female friendships are significant to many Black females because they represent a homeplace, or a safe space. This study uses Baxter and Montgomery's (1996 Baxter , L. A. , & Montgomery , B. M. ( 1996 ). Relating: Dialogues and dialectics . New York , NY : The Guilford Press . [Google Scholar], 1998 Baxter , L. A. , & Montgomery , B. M. ( 1998 ).

Black feminist thought: Knowledge, consciousness, and the politics of empowerment ( ed.) , 2nd . New York , NY : Routledge . [Google Scholar]) Black feminist thought to understand the interplay of contradictions in the stories that Black females tell in their friendship groups. The contradictions embedded in the stories were finances (spending/saving), language (“good”/“bad” English), appearance (satisfaction/dissatisfaction), and race (acceptance/rejection of otherness). The interaction of these tensions showed that the friends engaged in group segregation and integration, which ultimately enabled them to freely express their culturally based truths without fear of marginalization.     

Formal features in children's science television: Sound effects,visual pace,and topic shifts

This study analyzes the auditory, visual, and information‐presentation pace of children's science television programs. These half‐hour programs averaged more than 19 sound effects per minute, 14 visual changes (cuts, wipes, and fades/dissolves) per minute, and more than 27 topic shifts per program. These results indicate that the current crop of programs presents content at a pace that may reduce their effectiveness.
