The long‐term effect of social comparison on academic performance

The present study was part of a large‐scale cohort study among several thousand students in the Netherlands. The purpose of the study was to investigate the long‐term effects of comparison choice, i.e., comparison with a target performing better or worse than oneself, and academic comparative evaluation, i.e., the extent to which one thinks one's performance is better or worse than that of others, on scores on standardized tests for reading comprehension and mathematics. While controlling for earlier performance, the results showed that both comparison choice and academic comparative evaluation positively predicted test scores over a period of 2 years. Moreover, it was found that the positive effect of comparison choice only applied to students with a favorable comparative evaluation. Copyright © 2009 John Wiley & Sons, Ltd.     

Age and Gender Differences in Mate Selection Criteria for Various Involvement Levels

The present study investigated mate preferences for five different levels of relationship involvement—marriage, serious relationship, falling in love, casual sex, and sexual fantasies–among individuals of 20, 30, 40, 50, and 60 years of age. Consistent with an evolutionary perspective, men preferred mates who were higher in physical attractiveness than themselves, whereas women preferred mates who were higher in income, education, self–confidence, intelligence, dominance, and social position than themselves. The lower the level of relationship involvement, the lower were the preferred levels of education, physical attractiveness, and, particularly for males, preferred intelligence in comparison to oneself. For sexual fantasies, men and women preferred mates who were higher in physical attractiveness than those they preferred for real partners. There were few age differences in mate preferences, although older individuals set higher standards for a potential mate’s education.     

Examining a model of dispositional mindfulness, body comparison, and body satisfaction

The present study examined the links between dispositional mindfulness, body comparison, and body satisfaction. It was expected that mindfulness would be associated with less body comparison and more body satisfaction. Two models were tested: one exploring body comparison as a mediator between mindfulness and body satisfaction and an alternative model exploring mindfulness as a mediator between body comparison and body satisfaction. In an online survey, 1287 Dutch women answered questions concerning dispositional mindfulness, body comparison, and body satisfaction. Results showed that body comparison was related negatively to both dispositional mindfulness and body satisfaction, whereas the two latter variables were related positively. Body comparison partially mediated the relation between mindfulness and body satisfaction. However, a stronger indirect effect was noted in the alternative model, where mindfulness partially mediated the link between body comparison and body satisfaction.     

Self and partner personality and responses to relationship threats

Two studies examined the relations between three different types of jealousy and personality characteristics of self and partner in two large heterogeneous community samples of heterosexual couples (459 and 230 couples, respectively). It was expected that partners would resemble each other to some extent in both the experience of different types of jealousy and personality characteristics, and that self-reported levels of neuroticism (+) and extraversion (−) would be related to higher levels of jealousy. Moreover, it was expected that partner extraversion would be related positively to levels of jealousy, and that similarity with regard to personality characteristics would be related to lower levels of jealousy. Results largely supported our expectations with regard to both partner similarity and self-reported personality characteristics. However, our expectations with regard to partner extraversion and similarity were not supported.     

The Effect of Target's Physical Attractiveness and Dominance on STD-Risk Perceptions

Utilizing a 2 × 2 design, the present study examined the effect of a female's physical attractiveness and dominance on men's sexual motivation and sexually transmitted disease (STD) risk perceptions in a sample of 72 heterosexual male college students. As predicted. participants were more motivated to have sex with more physically attractive women. Nonetheless, they also believed that the more physically attractive women had been more promiscuous in the past, and believed that unprotected sex with a physically attractive woman implied a relatively somewhat higher risk of contracting an STD. In contrast, the more socially dominant women were perceived as having practiced safer sex more regularly and as having had less risky sexual partners in the past. Practical implications of this study are discussed.     

Empathic concern: Distinguishing between tenderness and sympathy

The present research proposes that empathic concern, as assessed by six items of the ERQ, consists of two separate emotions, i.e., tenderness and sympathy. To test this assumption, nine studies were conducted among, in total, 1,273 participants. In these studies participants were presented with a hypothetical scenario of someone in need, after which empathic concern was assessed. Factor analyses showed that, indeed, the ERQ items that assess empathic concern can be split up in two factors, that is, one reflecting sympathy and one reflecting tenderness. In addition, in line with previous studies, our research showed that, in response to a need-situation that reflects current needs, individuals scored higher on the ERQ factor reflecting sympathy than on the ERQ factor reflecting tenderness. Findings are discussed in terms of the practical and theoretical implications of distinguishing between sympathy and tenderness.     

Empathy in intimate relationships: The role of positive illusions

Previous studies have shown empathy to be an important aspect of a high quality intimate relationship. Likewise, positive illusions about a partner's characteristics have been shown to contribute to relationship quality. The present study connects these issues by examining the degree to which individuals hold positive illusions about a partner's level of empathy, and the extent to which these positive illusions are related to relationship quality and adjustment in a sample of 55 couples. Results showed that positive illusions concerning a partner's level of empathy were only held by women. In addition, people's evaluation of relationship quality and adjustment was consistently related to both their own and their partner's positive empathy illusions. Finally, an interaction effect was found between participant sex and the partner effect of positive empathy illusions: the illusions held by the partner (only for men) were related to relationship quality. Results and implications for theory and relationship counseling are discussed.     

Jealousy in response to online and offline infidelity: the role of sex and sexual orientation

The goal of the present study was to examine the emotional content and intensity of jealousy in response to different types of infidelity (both online and offline unfaithful partner behaviors) among Dutch heterosexuals (n = 191) and homosexuals (n = 121). Based on previous research (Dijkstra, Barelds & Groothof, 2010), participants were presented with ten jealousy‐evoking situations following which the intensity of two different emotional aspects of jealousy was assessed (betrayal/anger and threat). Results showed that scenarios describing a partner having sex with someone else or falling in love with someone else primarily evoked betrayal/anger‐related jealousy, whereas scenarios describing an emotional connection between a partner and someone else primarily evoked threat‐related jealousy. In addition, women experienced more jealousy than men in response to scenarios in which a partner engaged in potentially extra‐dyadic online (but not offline) behaviors. Finally, compared to same‐sex heterosexuals, homosexuals, both male and female, responded with less intense jealousy to scenarios describing a partner having sex with someone else. Implications for the treatment of (internet) infidelity are discussed.     

Women's meta-perceptions of attractiveness and their relations to body image

The present study examined meta-perceptions of attractiveness among women. More specifically, ratings were collected about how women thought their partner, family and friends, and strangers would view their physical attractiveness. In an online survey, 1287 Dutch women (aged 19-80 years) answered questions concerning meta-perceptions of attractiveness, demographic data, body mass index (BMI), body image (Body Areas Satisfaction Scale, self-rated general physical attractiveness, and actual-ideal weight discrepancy), and self-esteem. Results showed that women's meta-perceptions of attractiveness reflected the level of closeness of the relationship with the other person, with the most positive meta-perceptions reported for the partner, followed by those for family and friends, and the least positive meta-perceptions for strangers. Meta-perceptions were strongly related to body image, self-esteem and BMI. Self-ratings of attractiveness appeared to be lower than all meta-perceptions of attractiveness, suggesting that women are aware of their own negative self-bias and/or other people's positive bias.
