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) Â 2 (conspicuous luxury vs. inconspicuous nonluxury) between-subjects experimental study conducted with an Amazon Mechanical Turk sample (N ¼ 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 ¼ 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. Relative to women, men are more likely to purchase and register conspicuous sports cars in the United States and cars of well-known luxury brands (Bowling, 2013;Macesich, 2014). Previous research has demonstrated that men may use these luxury cars to impress women, given that they may function as a signal of mate value (Griskevicius et al., 2007). And indeed, a man who was seated in a luxury car was perceived as more attractive by women compared to the same man seated in a nonluxury car (Dunn & Searle, 2010). Hence, men appear to use showy spending to attract women in intersexual competition contexts. Sundie et al. (2011) further revealed that men's flaunting of luxury goods signals their desirability as a shortterm (rather than long-term) mate. In addition, the study of Saad and Vongas (2009) indicated that men who drove a luxury sports car yielded higher testosterone levels compared to when they drove a nonluxury car. Moreover, Saad and Vongas found that male testosterone levels also rose when confronted with other men who displayed luxury (vs. nonluxury goods) in the presence of a female confederate. These latter results suggest that intrasexual competition processes may also incite men's

Recent evolutionary experimental psychological research found that high verbal proficiency (VP) increased the perceived attractiveness of individuals (more so for males than females), especially in the context of a long-term relationship. Our study had the objective of replicating and extending this research. Similar to previous studies, audio files in which speakers performed scripted self-presentations that had equal content but varied on VP were used as stimuli for opposite-sex participants. VP was found to increase attractiveness ratings. The effects were mostly small for numerous variables relating to short-term mating, whereas they were moderate to large for long-term mating. Our participants attributed more future income, but not more total number of mates to speakers with higher VP. Female menstrual cycle effects on attractiveness ratings were not found. Contrary to former research, being more verbally proficient was not found to be more beneficial for one sex over the other.

We provide a literature overview of 30 years of research on the amount of invested mental effort (AIME, Salomon, 1984), illuminating relevant literature in this field. Since the introduction of AIME, this concept appears to have vanished. To obtain a clearer picture of where the theory of AIME has diffused, we conducted a literature search focusing on the period 1985–2015. We examined scientific articles (N = 244) that cite Salomon (1984) and content-analyzed their keywords. Based on these keywords, we identified seven content clusters: affect and motivation, application fields, cognition and learning, education and teaching, media technology, learning with media technology, and methods. We present selected works of each content cluster and describe in which research field the articles had been published. Results indicate that AIME was most commonly (but not exclusively) referred to in the area of educational psychology indicating its importance regarding learning and education, thereby investigating print and TV, as well as new media. From a methodological perspective, research applied various research methods (e.g., longitudinal studies, experimental designs, theoretical analysis) and samples (e.g., children, college students, low income families). From these findings, the importance of AIME for further research is discussed.

By applying the handicap principle, researchers have investigated men’s conspicuous purchases of high-status products as part of sexual signaling systems. Studies have suggested that, as part of short-term mating strategies, men are particularly willing to engage in conspicuous consumption to attract mates. Yet, this research has neglected to examine how relationship status influences conspicuous consumption. In our web-based study involving 352 participants (229 women), men tending towards short-term mating reported greater purchase intentions for a high-status smartphone only when single or in uncommitted relationships, while no association surfaced between mating strategy and conspicuous consumption among men in committed relationships. Results also revealed that, independent of mating strategy and income, single men and men in uncommitted relationships were more willing to purchase a low-status smartphone. Relationship status did not affect women’s conspicuous consumption. With these findings, we argue that relationship status significantly moderates men’s conspicuous consumption, as well as discuss purchases of low-status products as possible signals of men’s interest in long-term mating.
