Meinungsführer in Online-Diskussionsforen
(2016) Scheiko, Ljewin; Schenk, Michael
The study deals with opinion leaders in internet forums. Questions and hypotheses of classical opinion leader studies are transferred and adapted to the specific characteristics of the communication process in internet forums. Due to the width of the field of research, the study is divided into three research areas, each with a specific objective. In the first research area general findings on users of internet forums are obtained. In the second research area opinion leaders are profiled in detail and the relevance of shared information in internet forums is evaluated as well as the degree of influence of opinion leaders on other users is measured. In the third research area, the network structure of internet forums is analyzed and the network positions of opinion leaders are identified. To meet the different objectives optimally, a complex study design, consisting of an Internet-representative online survey and a triangulation of online survey and network analysis, is used.
Older adults’ internet use, outdoor activity, and the urban environment : empirical analysis
(2021) Schehl, Barbara; Kirn, Stefan
In an ageing society, information technology (IT) can be a powerful tool to support older adults in staying physically, mentally, and socially active. A growing number of studies show positive effects of Internet use on active ageing. Specifically, understanding the relationship between older adults’ Internet use and their participation in outdoor activity has gained attention. However, little is known about the role of specific online activities, as previous research mainly considered general Internet use, e.g., writing emails and browsing the Web, which does not provide a rationale for increased outdoor activity. Another important factor affecting outdoor activity is the urban environment in which older adults live, especially as the environment can either motivate or hinder participation in outdoor activity. Against this backdrop, the aim of this thesis is to get a better understanding of the association between Internet use, the urban environment, and participation in outdoor activity. By adopting an ecological perspective, this dissertation is first in comprehensively assessing this association. Three studies provide empirical insights into patterns of factors and contribute an enhanced understanding of the association between older adults’ Internet use, the urban environment, and outdoor activity. In summary, this thesis contributes to a relevant growth of knowledge on older adults’ Internet use and outdoor activity. The approach in this thesis uncovered important differences in the roles of individual factors as well as environmental factors in explaining older adults’ outdoor activity. Based on this contributions, important implications for research can be identified. For instance, future research can use the conceptual framework as a basis to investigate further types of outdoor activities and further types of online activities, such as social networks and messaging services which attain increasing relevance for the group of older adults. Further, this dissertation also has some practical implications, for example, as all three studies showed that socio-demographic predictors play important different roles, the findings are specifically relevant to identify specific groups of older adults. For instance, developers and providers can tailor their services to the needs of older adults, e.g., by designing responsive and barrier-free interfaces that adapt to individual capabilities in cognition, vision, and motor function. Concluding, older adults should be encouraged to go online because the Internet increasingly provides information about opportunities and offerings in the city. The findings of this dissertation provide a rationale for the development of online services that offer neighborhood information and ultimately support older adults to be active outdoors.
The psychology of privacy: Analyzing processes of media use and interpersonal communication
(2017) Dienlin, Tobias; Trepte, Sabine
What is the psychology of privacy? How do people perceive privacy? Why do people disclose personal information on the Internet, and what does this reveal about our their personalities? With four studies, this cumulative dissertation discusses potential answers to these questions. Study 1 (“The Privacy Process Model”) proposes a new privacy theory, the so-called Privacy Process Model (PPM). The PPM states that privacy consists of three major elements: the privacy context, the privacy perception, and the privacy behavior. In order to balance the three elements people constantly engage in a privacy regulation process, which can be either explicit/conscious or implicit/subconscious. Through concrete examples of new digital media, several implications of the PPM are demonstrated. Study 2 (“Is the Privacy Paradox a Relic of the Past?”), which is co-authored by Prof. Dr. Sabine Trepte, analyzes the privacy paradox through the results of an online questionnaire with 579 respondents from Germany. By adopting a theory of planned behavior-based approach, the results showed that self-disclosure could be explained by privacy intentions, privacy attitudes, and privacy concerns. These findings could be generalized for three different privacy dimensions: informational, social, and psychological privacy behaviors. Altogether, Study 2 therefore suggests that the privacy paradox does not exist. Study 3 (“An Extended Privacy Calculus Model for SNSs”), co-authored by Prof. Dr. Miriam J. Metzger, builds upon the results of Study 2 and investigates whether psychological antecedents can explain not only online self-disclosure but also online self-withdrawal. Using a privacy calculus-based approach, the study analyzes data from a U.S.-representative online sample with 1,156 respondents. The results showed that self-disclosure could be explained both by privacy concerns and expected benefits. In addition, self-withdrawal could also be predicted by both privacy concerns and privacy self-efficacy. In conclusion, Study 3 demonstrates that perceived benefits, privacy self-efficacy, and privacy concerns together predict both online self-disclosure and online self-withdrawal. Study 4 (“Predicting the Desire for Privacy”), also co-authored by Miriam J. Metzger, analyzes the relationship between the desire for privacy and different facets of personality. In Study 4a, an online questionnaire with 296 respondents was conducted and in Study 4b, a laboratory experiment with 87 participants was run. The results of the questionnaire showed several significant relationships: For example, respondents who reported lacking integrity and being more shy, less anxious, and more risk averse were all more likely to desire privacy. The experiment showed a statistical trend that participants who had written an essay about past negative behaviors were more likely to express an increased desire for privacy from other people; in addition, an implicit association test (IAT) showed that participants whose IAT results implied higher lack of integrity also desired more privacy from government surveillance. In conclusion, the results evidence that the desire for privacy relates with several aspects of personality and, notably, also with personal integrity. In the overarching discussion, the results of the aforementioned studies are combined in order to provide an updated picture of privacy. This picture suggests that online self-disclosure is not paradoxical but explainable. Being able to understand online privacy behaviors is important; however, this is not only because the Internet has paramount importance in social and professional contexts, but also because people’s desire for privacy can reveal central aspects of personality, such as one’s own personal integrity. Finally, several societal implications are discussed. It is argued that modern societies should try to design new cultural artifacts about privacy, update old and obsolete behavioral patterns with regard to privacy, foster a better understanding of the conceptual nature of privacy, work toward new and more protective privacy laws, and aim to leverage overall privacy literacy.
VERZERRT. SCHRILL. GESPALTEN. Meinungsklima und Diskursqualität im Internet und ihre Wirkungen auf den Journalismus
(2022) Fulda, Stefanie; Schweiger, Wolfgang
Journalists play a dual role in shaping public opinion. On one hand, they influence public opinion through their publications. At the same time, they themselves continuously monitor public opinion and orient themselves to it. It seems obvious that the way journalists perceive the world can also influence their work. In fact, it has not yet been studied in terms of the perceived climate of opinion. It is similar with the perceived digital debate culture. Quality, tone and content of online discourses are already widely addressed under keywords such as incivility and hate speech. Effects on journalism are also mentioned, but they don´t focus on how journalists perceive the combined climate of opinion and quality of discourse and how this affects their work. In fact, user comments, individual opinions and opinion leaders are of particular importance to journalists in this perception. Due to the still incomplete state of research on the perception effects of public opinion and discourse quality on journalism, qualitative, guideline-supported interviews were therefore set up on the question "How do journalists perceive opinion climate and discourse quality on the Internet and how does this affect their work?" in order to approach the possible manifestations of this topic in an explorative manner. For these interviews, which lasted 1 - 1.5 hours, 20 journalists from all over Germany were interviewed. The net sample of participating journalists differed according to department, type of employment, age, location, gender, subject areas and degree of position, with the aim of obtaining answers from as many different journalists as possible and being able to compare the answers of certain groups with each other. In addition, a website was created as a central information point for the project. With the help of a repetitive change of perspective in the survey, which addresses the approach and considerations of the interviewees, but also inquires how, from the interviewees point of view, other journalists deal with the same issue, it was possible to identify some hidden perceptual effects. Beginning with the question about the central sources of public opinion perception, via processing and the mechanisms in this process, to the recognizable effects on journalistic work, it was thus possible to trace the path of perception of opinion climate and discourse quality to the effects on journalistic topic selection and topic processing. A key finding of the survey is that it remains unclear to the group of journalists surveyed whether the perceived climate of opinion on the Internet is representative of society as a whole - many do not rule out parallels of digital and general public opinion. At the same time, it is rationally clear to many journalists that they should not be too impressed by the experiences on the Net, since these represent only a small section of society, but emotionally it does happen - because the quality of the experienced, digital discourse is so impressive. On the other hand, almost all of the journalists surveyed assume that the perceived climate of opinion influences their journalistic work, but show a lack of clarity about the extent to which they are personally affected by this in their work. They do not know the concrete effects. Finally, it became obvious that journalists base their perception of public opinion quite significantly on the perceived quality of discourse. This is an understandable approach, but one that harbors the risk of misperceptions due to third person, negativity or false uniqueness effects, to name just a few of the most important potential distortions of perception. This has consequences: If those who report on public opinion are subject to a distorted perception, then they bring this into their reporting, which reinforces the tendency for recipients to also be subject to a distorted perception of public opinion. Citizens, in turn, express themselves in social media or below journalistic articles in the comments. These are read by editorial teams and in turn used for journalistic reporting. This is where the circle closes, because this is how recipients and journalists influence each others distorted perceptions and draw conclusions about public opinion in society. Minority opinions are perceived as majority opinions, the emotionally heated discourse on the Internet shapes the impression of a growing polarization of society, and journalism carries this idea into its reporting. The consequence is a possible misinterpretation of public opinion by journalistic media, so that journalism runs the risk of arguing past the actual public opinion of society through a distorted perception of public opinion and discourse quality on the Internet.
Vom Glauben, Berge versetzen zu können : subjektive Beurteilung von Medienqualität und Selbstwirksamkeit als Wegbereiter politischen Wissens
(2016) Schmitt, Josephine B.; Trepte, Sabine
The Internet has become a significant source for political information especially for younger generations. However, the evaluation and selection of relevant information becomes increasingly difficult as a growing number of diverse sources and content are available. Based on this observation, the present study aims to get to the bottom of the questions (1) how adolescents navigate through the vast amount of available information on the Internet (i.e., evaluation and selection of information sources) and (2) how they acquire political knowledge. More precisely the study analyzes which psychological factors contribute to adolescents’ political learning from online information sources and how these processes may be supported by media literacy programs in school. The book draws from and connects different lines of existing theoretical and empirical research: studies on perceived information quality (Wolling, 2009), social-cognitive theory (Bandura, 1986; Niemi, Craig, & Mattei, 1991) as well as research from learning psychology (e.g., Salomon, 1984). I propose that perceived information quality, media self-efficacy, internal political efficacy, and political knowledge should be understood as consecutively linked. To address the mentioned questions, I conducted a three-wave panel study with adolescents (9th to 13th grade). Moreover, a subsample participated in a media literacy intervention that took part before the second wave. Results demonstrate that perceived information quality of online news sources influences media self-efficacy, which, in turn, is related to internal political efficacy. Furthermore, internal political efficacy is being shown to positively influence political knowledge. Perceived information quality engenders trust in an individual’s media-related and political abilities, which leads to a more successful processing of political information among young adults. However, results regarding the effectiveness of the media literacy intervention are mixed. I found no direct effect of the media literacy intervention, nevertheless, a significant improvement in knowledge of the experimental group may indicate some indirect effects. All in all, these findings underline the importance of analyzing not only news media exposure but also perceived information quality as a predictor of political knowledge. Moreover, the results shed some light on the mediating role of media self-efficacy and political efficacy in the context of political knowledge acquisition. It can be concluded that not only exposure to qualitatively good sources for political information leads to an increase in political knowledge but also giving young adults the feeling that they are using sources of high quality.
