Groups who share information in computer-mediated settings often have to deal with the issue of anonymity. Previous research has shown that only people with a prosocial orientation--that is, those whose main interest is to add to the benefit of the group as a whole--are willing to share information in anonymous situations. The willingness to share information by those people with a proself orientation--that is, those who put more emphasis on their personal benefit--can be increased by providing photographs of the other group members. The information-sharing behavior of prosocials, however, suffers from such a deletion of anonymity. In an online experiment, we examined how information-sharing behavior of proselfs may be increased without negatively influencing the information-sharing behavior of prosocials in an online setting. It was shown that even proselfs share information if the group members are visualized in a homogeneous way, while prosocials' information-sharing behavior is not impaired by this visualization. In addition, the results suggest that people's perceived homogeneity of the online group, as well as the importance of the collective goal, are the underlying processes of this effect. These results have important practical implications for the design of online information-sharing settings. Source

For effective communication and collaboration in learning situations, it is important to know what the collaboration partners know. However, the acquisition of this knowledge is difficult, especially in collaborating groups with spatially distributed members. One solution is the Knowledge and Information Awareness approach developed by Engelmann and colleagues. This approach provides spatially distributed collaborating group members digital visualizations of the knowledge and the information underlying the knowledge of their partners. The current article gives an overview regarding the empirical studies that have demonstrated the efficacy of the Knowledge and Information Awareness approach: A first set of experimental studies confirmed the effectiveness of this approach to foster both knowing what the collaborators know and knowing to which information they have access. A second set of experimental studies identified the underlying impact factors of the Knowledge and Information Awareness approach. The third set of experimental studies showed the potential of the approach to overcome arising collaboration barriers. The article concludes with a discussion regarding the limits of the approach and its applicability in real learning settings, such as in schools. © 2014, Baywood Publishing Co., Inc. Source

Group awareness has become an important concept since it was introduced into the field of computer-supported collaborative learning. This paper discusses current trends and future directions in this research field. It is argued that the development and implementation of tools should be complemented by systematic explorations into the mechanisms that moderate the relationship between group awareness and learning. It is suggested that variations in tool design features are a starting point for furthering our understanding of the processes involved in group awareness. Based on the contributions in this special issue, eight areas for future empirical investigations are identified. The paper concludes with some theoretical considerations on the nature of group awareness. © 2010 Elsevier Ltd. All rights reserved. Source

How can social network sites (SNS) foster relationships when most status updates on SNS are mainly entertaining and not very intimate? This finding cannot be explained by classical social psychological theories such as social penetration theory which regard disclosure intimacy as the main driver of relational outcomes. By building on literature on the role of capitalization and humor in relationship formation and maintenance, this paper suggests two alternative paths from public self-disclosure to relational outcomes. Respondents judged the content and relational effects of own and friends' status updates as well as private conversations. In general, all types of messages were mainly positive and entertaining. The more intimate communication took place in private conversations; here, the classical link between disclosure intimacy and feeling connected still held. However, positive and entertaining self-disclosures also increased the feeling of connection, especially when reading friends' updates. Interestingly, interaction partners' responsiveness did not play a significant role, indicating that results from dyadic face-to-face interactions do not hold for public communication on social media. The study contributes to the development of a more differentiated model on the role of self-disclosure on SNS. © 2014 Elsevier Ltd. All rights reserved. Source

Although film, television, and video play an important role in modern societies, the extent to which the similarities of cinematographic images to natural, unmediated conditions of visual experience contribute to viewers' comprehension is largely an open question. To address this question, we compared 20 inexperienced adult viewers from southern Turkey with groups of medium- and high-experienced adult viewers from the same region. In individual sessions, each participant was shown a set of 14 film clips that included a number of perceptual discontinuities typical for film. The viewers' interpretations were recorded and analyzed. The findings show that it is not the similarity to conditions of natural perception but the presence of a familiar line of action that determines the comprehensibility of films for inexperienced viewers. In the absence of such a line of action, extended prior experience is required for appropriate interpretation of cinematographic images such as those we investigated in this study. © 2010 The Author(s).
