Mobile apps are very popular. However, this is not true for every app, with some apps receiving millions of downloads, while other apps are mostly ignored. We investigate the popularity of apps in terms of downloads by focusing on two salient cues: (a) online recommendations (e.g., presence and valence of online reviews) and (b) visual characteristics of app icons (e.g., use of visual metaphors and anthropomorphism). Study 1 was a field study in which we content-analyzed 500 apps from the "transportation" subcategory of the Google Play Store. We found that the presence and valence of online reviews, as well as the presence of visual metaphors in app icons were positively related to the number of app downloads. Study 2 was an experiment in which we presented participants with different app icons containing different types of visual metaphors. We again found that app icons with visual metaphors led to more positive attitudes towards the apps and behavioral intentions. Combined, our studies show that both online consumers (through online reviews) and app designers (through visual design) impact an app's popularity.

This study examines startups' social media communication practice in China through the theoretical lens of dialogic communication. Drawing interdisciplinary insights from public relations and computer-mediated communication, this study explored conversational human voice and social presence as antecedents of startups' dialogic communication with publics on social media and explored publics' trust and positive word-of-mouth as potential outcomes of this process. Results from an online survey with 1061 social media users in China who had followed at least one startup organization revealed that startups' conversational human voice and social presence on social media helped drive organization–public dialogic communication, which in turn fostered publics' trust and positive word-of-mouth toward startups. Theoretical and practical implications are discussed.

The power of app-driven mobile phones was first unleashed in 2011 when they were used to mobilize protesters and gain support for political movements in the United States and abroad. Mobile devices have since become the bedrock of political activism. To examine the influence of app reliance on offline and online political participation, this study builds on the Orientation-Stimulus-Reasoning-Orientation-Response (O-S-R-O-R) model by (a) applying the model to mobile apps, (b) testing whether trust in, and reliance on political discussion are mediators between reliance on apps and political participation, and (c) using trust in both offline and online discussion as measures of cognitive elaboration. This study's path model suggests that app reliance is related to online political discussion, which, in turn, is related to online political participation, but not offline participation. Although both offline and online discussion are linked to offline and online trust in political discussion, trust in political discussion does not influence either offline or online political participation.

Research on language development suggests that children from low-income families hear nearly 30 million words less than their higher income counterparts (Hart & Risley, 1999). This paper explores parent perceptions and attitudes toward two mobile interventions (Text4baby and Univision Contigo) designed to support parents' engagement with their young children as a way of reducing the language gap and improving child outcomes. We conducted eight focus groups with parents who were users of either service. Using general inductive analysis of the transcript data, we found that parents enrolled in the Text4baby service were relatively unaware of the video text messages and almost never clicked the links. Univision Contigo users, on the other hand, more frequently recalled seeing videos encouraging parent–child interaction and particularly liked that these videos came as multimedia messages (MMS). We interpret findings through a social cognitive theory lens and provide recommendations for incorporating video into parent-targeted mobile interventions.

Phubbing—ignoring another person in order to use a smartphone instead—is an increasingly common behavior that disrupts interactions and harms relationships. Using the frameworks of the theory of planned behavior and an interaction value approach, we examined the driving factors of phubbing frequency. Four preregistered predictors were tested: attitudes toward phubbing, subjective norms of phubbing, interaction value, that is, the extent of valuing a social interaction, and the perceived interaction value of the partner. After having had lunch together, a total of 128 participants in 64 dyads filled out a survey assessing the four predictors. Dyadic linear mixed model analyses confirmed that a more positive attitude toward phubbing increases phubbing, as well as being phubbed. Moreover, we disentangled screen-sharing time (i.e., using a phone together), phone use, co-present phone use (i.e., using a phone alone), and phubbing: we found that valuing the social interaction more decreased phone use, but not phubbing, and holding more accepting subjective norms on phubbing increased co-present phone use, but not phone use in general. We further found that the person that used their phone first, phubbed more. Overall, this research extends our understanding of the factors driving phubbing and may be fruitfully harnessed to reduce phubbing.

This study uses co-orientation theory to examine the impact of mobile phone use on relational quality across three copresent contexts. It investigates the relationship between perceived similarity, actual similarity, and understanding of mobile phone usage on relationship outcomes, and uses a new measure of mobile relational interference to assess how commitment, satisfaction, and liking are affected by perceptions of relational partners' mobile phone use. Contrary to popular belief, the results from this study of 69 dyads reveals that, at least within a sample of young Americans, failing to adhere to injunctive (i.e., societal) norms regarding mobile phone usage does not impact relational quality. Rather, results indicate that perceived adherence to participants' own internal standards—by both the participant, and the participant's relational partner—and perceived similarity between partners were more influential.

Visual aesthetics is an essential part of our experience of mobile devices, but the ways in which it is accounted for in design have largely been overlooked. We investigate whether an aesthetization of mobile design is taking place and, if so, how it is being pursued through institutional practices in organizations. We conduct a visual analysis of all Nokia phone releases between 1992 and 2013 complemented by an interview series with key actors. The study reveals a continuous increase in aesthetic variation between 1998 and 2008, which is visible in the variation of colors, forms, and materials. The period between 2003 and 2008, which we term the "Grand" period, marks the peak of aesthetization of Nokia's devices. It exhibits great variation, and is visibly similar to aesthetics in the fashion industry. With the introduction of the slate form, we see a decrease in visual variation between 2009 and 2013. The interviews reveal how the visual design was driven by organizational strategies, such as customer segmentation in general, and an orientation toward the fashion industry, for example, in the creation of a fashion segment. The study reveals how aesthetic variation is weaved into a complex innovation system with sometimes conflicting demands deriving from, for instance, technology and user interaction.
