Current evolutionary research on human mating has largely ignored the fact that mating decisions may be heavily influenced by parents. Recent research, however, shows that parents and children may have conflicting mate preferences. Specifically, parents tend to have a relatively stronger preference for children to pair with mates with characteristics signaling high parental investment and cooperation with the in-group, whereas children tend to have a relatively stronger preference to pair with mates with characteristics signaling genetic quality. The present research among 242 young adults from Argentina showed that in this country the same parent-offspring conflict was observed as had been found previously in North America, the Netherlands, Uruguay, and Kurdistan. This result provides additional support for the universal character of this type of conflict. In addition, the present research expanded previous work by showing that the two conflict dimensions were indeed psychometrically independent, and that more conflict was reported by older and married participants. In addition, more conflict was reported among women who were more in favor of parental control over mate choice and among men who were higher in social comparison orientation.

In this study (N = 96), the role of social comparison in evaluating the quality of one's friendships and social relationships was examined. Participants who were exposed to a comparison target with a very dissatisfying social life evaluated their own social life as better than participants who were exposed to a comparison target with a very satisfying social life. However, this effect was only found among individuals high in the individual characteristic social comparison orientation. It is concluded that only individuals with a dispositional tendency to compare themselves with others will base the evaluation of their social life to an important extent on what they see in others.

This study examines gender differences in the jealousy-evoking nature of rival characteristics in two Spanish-speaking countries (Argentina and Spain). A total of 388 Spanish students and 444 Argentinean students participated in the study. First, the cross-cultural validity of a Dutch scale containing 56 rival characteristics was examined. A factor analysis distinguished four dimensions (i.e., social power and dominance, physical attractiveness, physical dominance, and social-communal attributes). After the analysis, the final scale contained in total 24 items. Results showed that in Argentina and Spain combined, men experienced more jealousy than women when their rival was more physically dominant. In contrast, women experienced more jealousy than men when their rival was more physically attractive, had more social-communal attributes, and had more social power and dominance. In both genders, social-communal attributes was the most jealousy-evoking characteristic, followed by physical attractiveness in women and by social power and dominance in men. In addition, in Argentinean participants but not in Spanish participants, those high in social comparison orientation found the rival characteristics more jealousy evoking.These results provide strong support for the evolutionary hypothesis of gender differences in the rival characteristics that may evoke jealousy. Small size effect differences were found between the two countries and only regarding social-communal attributes.

This study addressed the question whether the affect evoked by social comparisons and individual differences in social comparison orientation (SCO) may predict the development of burnout over a period of one year. The participants were 93 nurses (25 males and 68 females) who filled out a questionnaire twice, with an interval of about one year. Comparisons with others performing better than oneself (upward comparisons) were reported to occur more often, to evoke more positive affect, and to invoke less negative affect than comparisons with others performing worse than oneself (downward comparisons). Those who responded at Time 1 (T1) with more positive affect to upward comparison and with less negative affect to downward comparisons, showed a decrease in burnout at Time 2 (T2). In addition, those who responded with relatively more negative affect to upward comparisons at T1, showed an increase in burnout at T2, but only when they were high in SCO. It is concluded that in this population upward comparisons were more prevalent than, and evoked more favorable responses than, downward comparisons. The most important conclusion is that the affect evoked by social comparisons may predict future changes in burnout.
