  abstract  = {In the last decade, mobile device ownership has largely increased. In particular, smartphone ownership is constantly rising (A. Smith, 2015; Statista, 2016a), and there is a real hype for luxury brand smartphones (Griffin, 2015). These observations raise the question of which functions smartphones serve in addition to their original purposes of making and receiving calls, searching for information, and organizing. Beyond these obvious functions, studies suggest that smartphones express fashion, lifestyle, and one's economic status (e.g., B{\o}dker et al., 2009; Statista, 2016b; Vanden Abeele, Antheunis, \& Schouten, 2014). Specifically, individuals seem to purchase and use conspicuous luxury brand smartphones to display and enhance status (D. Kim et al., 2014; M{\"u}ller-Lietzkow et al., 2014; Suki, 2013). But how does owning a conspicuous, high-status smartphone contribute to status, and which benefits may these status boosts provide to their owners? From an evolutionary perspective, status carries a lot of advantages, particularly for males; high status grants them priority access to resources and correlates with their mating success (van Vugt \& Tybur, 2016). In this sense, research suggests that men conspicuously display their cell phones to attract mates and to distinguish themselves from rivals (Lycett \& Dunbar, 2000). In a similar vein, evolutionarily informed studies on conspicuous consumption indicate that the purchase and display of conspicuous luxuries (including mobile phones and smartphones) relate to a man's interest in uncommitted sexual relationships and enhance his desirability as a short-term mate (Hennighausen \& Schwab, 2014; Saad, 2013; Sundie et al., 2011). Drawing on these findings, this doctoral dissertation investigated how a man is perceived given that he is an owner of a high-status (vs. nonconspicuous, low-status) smartphone as a romantic partner and male rival. This was done in three experiments. In addition, it was examined how male conspicuous consumption of smartphones interacted with further traits that signal a man's mate quality, namely facial attractiveness (Studies 1 and 2) and social dominance (Study 3). Study 1 revealed that men and women perceived a male owner of a conspicuous smartphone as a less desirable long-term mate and as more inclined toward short-term mating. Study 2 replicated these results and showed that men and women assigned traits that are associated with short-term mating (e.g., low loyalty, interest in flirts, availability of tangible resources) to a male owner of a conspicuous smartphone and perceived him as a stronger male rival and mate poacher, and less as a friend. The results of Study 2 further suggested that specifically more attractive men might benefit from owning a conspicuous smartphone in a short-term mating context and might be hence considered as stronger male rivals. Study 3 partially replicated the findings of Studies 1 and 2 pertaining to the effects of owning a conspicuous smartphone. Study 3 did not show different effects of conspicuous consumption of smartphones on perceptions of a man dependent on the level of his social dominance. To conclude, the findings of this doctoral dissertation suggest that owning a conspicuous, high-status smartphone might not only serve proximate functions (e.g., making and receiving calls, organization) but also ultimate functions, which relate to mating and reproduction. The results indicate that owning a conspicuous smartphone might yield benefits for men in a short-term rather than in a long-term mating context. Furthermore, more attractive men appear to benefit more from owning a conspicuous smartphone than less attractive men. These findings provide further insights into the motivations that underlie men's purchases and displays of conspicuous, high-status smartphones from luxury brands that reach beyond the proximate causes frequently described in media and consumer psychological research. By applying an evolutionary perspective, this doctoral dissertation demonstrates the power and utility of this research paradigm for media psychological research and shows how combining a proximate and ultimate perspective adds to a more profound understanding of smartphone phenomena.},

  abstract  = {Previous research found that men conspicuously consume luxury products to attract a mate and to signal their mate value. However, these studies have yet neglected to investigate the function of male conspicuous consumption in same-sex competition. Given that intersexual selection and intrasexual selection are closely related processes, it stands to reason that a further function of male conspicuous consumption could be to impress and deter same-sex rivals. An 2 (intrasexual competition context vs. control) × 2 (conspicuous luxury vs. inconspicuous nonluxury) between-subjects experimental study conducted with an Amazon Mechanical Turk sample (N = 160) revealed that men reported both higher liking of and an intent to purchase a conspicuous luxury car compared to an inconspicuous nonluxury car due to increased feelings of social status. This effect was stronger in the intrasexual competition than in the control context. An additional perception study using a single-factor between-subjects design (conspicuous luxury vs. inconspicuous nonluxury car) among German men (N = 405) indicated that male participants rated a man who displayed a conspicuous luxury car more as a rival and mate poacher and less as a friend. They further perceived him to be superior on various mate value characteristics (i.e., attractiveness, intelligence, ambition, and status) and rated him as more oriented toward short-term mating. In sum, our findings add to previous research in the field of evolutionary consumer psychology by suggesting that male conspicuous consumption of luxuries may also serve a function in male-male competition.},
