THE EFFECT OF MEDIUM AND TASK ON DYADIC COMMUNICATION

A controlled laboratory study examined dyadic communication in face-to-face, telephone, and computer mediated text modes using high and low equivocal tasks. The dependent variables were decision time, consensus, change and communication satisfaction. The study failed to support media richness theory. While the findings support the hypothesis that decision time varies as a function of medium, they do not support similar hypotheses for consensus change and communication satisfaction. No support for hypothesized differences in decision time and consensus change as a function of the interaction of medium and task was found. However, there were consistent significant differences in all dependent measures based on task

Fostering shared knowledge with active graphical representation in different collaboration scenarios

This study investigated how two types of graphical representation tools influence the way in which learners use shared and unshared knowledge resources in two different collaboration scenarios, and how learners represent and transfer shared knowledge under these different conditions. Moreover, the relation between the use of knowledge resources, representation, and the transfer of shared knowledge was analyzed. The type of graphical representation (content-specific vs. content-unspecific) and the collaboration scenario (video conferencing vs. face-to-face) were varied. 64 university students participated. Results show that the learning partners converged in their profiles of resource use. With the content-specific graphical representation, learners used more appropriate knowledge resources. Learners in the computer-mediated scenarios showed a greater bandwidth in their profiles of resource use. A relation between discourse and outcomes could be shown for the transfer but not for the knowledge representation aspectIn dieser Studie werden die Wirkungen von verschiedenen Arten graphischer Repräsentation auf die Nutzung geteilter und ungeteilter Wissensressourcen in zwei verschiedenen Kooperationsszenarien untersucht. Des Weiteren wird analysiert, wie Lernende geteiltes und ungeteiltes Wissen unter diesen verschiedenen Bedingungen repräsentieren und transferieren. Schließlich wird die Beziehung zwischen der Nutzung von Wissensressourcen auf der einen Seite sowie der Repräsentation und dem Transfer geteilten Wissens auf der anderen Seite geprüft. Mit der Art der graphischen Repräsentation (inhaltsspezifisch vs. inhaltsunspezifisch) und dem Kooperationsszenario (Videokonferenz vs. face-to-face) werden zwei Faktoren experimentell variiert. 64 Studierende nahmen an der Studie teil. Ergebnisse zeigen, dass die Lernpartner in ihren Profilen der Ressourcennutzung konvergierten. Lernende, die durch die inhaltsspezifische graphische Repräsentation unterstützt wurden, verwendeten angemessenere Wissensressourcen. Lernende in den computervermittelten Szenarien weisen eine größere Bandbreite in ihren Profilen der Ressourcennutzung auf. Eine direkte Wirkung vom Diskurs der Lernenden auf die Entwicklung geteilten Wissens konnte für den Transfer, aber nicht für die Wissensrepräsentation gezeigt werde

Relationship Quality in the Context of Computer-Mediated Communication - A social constructionist approach

This paper contributes to possible answers to the question: What are the effects of computermediated communication on relationship qualities in organizations? To answer this question without oversimplifying the phenomena an adequate research methodology has to be found. First, the interrelationship between computer-mediated communication (CMC) and relationship quality is reviewed. CMC-theory will be described from three main perspectives and the risks and chances for relationship quality will be shown. The review indicates that most studies in the field are founded on a positivistic basis. Relationships are treated as static dyads neglecting contextual factors. Thus, the insight into relational processes in computerized environments remains limited. As an alternative a research methodology based on the epistemological stance of social constructionism is proposed. It will be explained, how the researchers’ view can be broadened by applying the method of the ‘narrative interview’ in practice based studies in computer-mediated contexts. In the concluding part, the contribution of this approach to research and practice will be discussed.Computer-mediated communication, relationship quality, social constructionism

A review of the empirical studies of computer supported human-to-human communication

This paper presents a review of the empirical studies of human-to-human communication which have been carried out over the last three decades. Although this review is primarily concerned with the empirical studies of computer supported human-to-human communication, a number of studies dealing with group work in non-computer-based collaborative environments, which form the basis of many of the empirical studies of the recent years in the area of CSCW, are also discussed. The concept of person and task spaces is introduced and then subsequently used to categorise the large volume of studies reported in this review. This paper also gives a comparative analysis of the findings of these studies, and draws a number of general conclusions to guide the design and evaluation of future CSCW systems

Building the Infrastructure: The Effects of Role Identification Behaviors on Team Cognition Development and Performance

The primary purpose of this study was to extend theory and research regarding the emergence of mental models and transactive memory in teams. Utilizing Kozlowski et al.’s (1999) model of team compilation, we examine the effect of role identification behaviors and argue that such behaviors represent the initial building blocks of team cognition during the role compilation phase of team development. We then hypothesized that team mental models and transactive memory would convey the effects of these behaviors onto team performance in the team compilation phase of development. Results from 60 teams working on a command and control simulation supported our hypotheses

Support-seeking, support-provision and support-perception in distressed married couples : a multi-method analysis

An emerging consensus argues for the importance of spousal support in our understanding of how relationships succeed or fail. This report covers two studies that examined support seeking, support provision and support perception in distressed married couples. In Study 1 a total of seventy distressed and seventy non-distressed couples participated in a survey study; in Study 2 twenty distressed and twenty non-distressed couples participated in an observational study. Global self-reports were used in both studies to assess spouses' support behaviour and perceived support. These measures were supplemented in Study 2 with measures of observed support behaviour and interaction-based perceived support as assessed during specific support interactions. Our self-report and observational measures consistently indicated that distressed marital couples display lower levels of positive support-seeking and emotional or instrumental support provision than non-distressed couples. We also found evidence for higher levels of negative support-seeking and provision behaviour in distressed couples, as compared to non-distressed couples. Distressed spouses also reported lower levels of global and interaction-based perceived support than non-distressed spouses

Depression, Relationship Quality, and Couples’ Demand/Withdraw and Demand/Submit Sequential Interactions

This study investigated the associations among depression, relationship quality, and demand/withdraw and demand/submit behavior in couples’ conflict interactions. Two 10-min conflict interactions were coded for each couple (N = 97) using Structural Analysis of Social Behavior (SASB; Benjamin, 1979a, 1987, 2000a). Depression was assessed categorically (via the presence of depressive disorders) and dimensionally (via symptom reports). Results revealed that relationship quality was negatively associated with demanding behavior, as well as receiving submissive or withdrawing behavior from one’s partner. Relationship quality was positively associated with withdrawal. Demanding behavior was positively associated with women’s depression symptoms but negatively associated with men’s depression symptoms. Sequential analysis revealed couples’ behavior was highly stable across time. Initiation of demand/withdraw and demand/submit sequences were negatively associated with partners’ relationship adjustment. Female demand/male withdraw was positively associated with men’s depression diagnosis. Results underscore the importance of sequential analysis when investigating associations among depression, relationship quality, and couples’ interpersonal behavior

Examining the components of children's peer liking as antecedents of school adjustment

Children’s social interactions with their peers influence their psychosocial adjustment; consequently, the relationship between class-wide peer liking, same-gender peer liking, and school adjustment was explored in two age groups. Peer liking was analysed using the social relations model (SRM). In Study 1, 205 children (103 female and 102 male, Mage = 7.15, SD = 7 months) completed measures of peer liking and school adjustment, and teachers completed the Short-Form TRSSA. In Study 2, 197 children (98 female and 90 male, Mage = 9.87, SD = 5.9 months) completed measures of peer liking and school adjustment. Both studies yielded evidence of reciprocal liking and individual differences in the ratings of liking awarded to, and elicited from, both peer groups. Multigroup path analysis, with groups created according to gender, revealed that elements of liking predicted different aspects of school adjustment with some variation according to age and gender. Together, these findings suggest that the SRM can be used to examine peer liking and underscore the importance of children’s peers for school adjustment
