Marital satisfaction and break-ups differ across on-line and off-line meeting venues.

Marital discord is costly to children, families, and communities. The advent of the Internet, social networking, and on-line dating has affected how people meet future spouses, but little is known about the prevalence or outcomes of these marriages or the demographics of those involved. We addressed these questions in a nationally representative sample of 19,131 respondents who married between 2005 and 2012. Results indicate that more than one-third of marriages in America now begin on-line. In addition, marriages that began on-line, when compared with those that began through traditional off-line venues, were slightly less likely to result in a marital break-up (separation or divorce) and were associated with slightly higher marital satisfaction among those respondents who remained married. Demographic differences were identified between respondents who met their spouse through on-line vs. traditional off-line venues, but the findings for marital break-up and marital satisfaction remained significant after statistically controlling for these differences. These data suggest that the Internet may be altering the dynamics and outcomes of marriage itself.

Sexual regret: evidence for evolved sex differences.

Regret and anticipated regret enhance decision quality by helping people avoid making and repeating mistakes. Some of people's most intense regrets concern sexual decisions. We hypothesized evolved sex differences in women's and men's experiences of sexual regret. Because of women's higher obligatory costs of reproduction throughout evolutionary history, we hypothesized that sexual actions, particularly those involving casual sex, would be regretted more intensely by women than by men. In contrast, because missed sexual opportunities historically carried higher reproductive fitness costs for men than for women, we hypothesized that poorly chosen sexual inactions would be regretted more by men than by women. Across three studies (Ns = 200, 395, and 24,230), we tested these hypotheses using free responses, written scenarios, detailed checklists, and Internet sampling to achieve participant diversity, including diversity in sexual orientation. Across all data sources, results supported predicted psychological sex differences and these differences were localized in casual sex contexts. These findings are consistent with the notion that the psychology of sexual regret was shaped by recurrent sex differences in selection pressures operating over deep time.

What is shared, what is different? Core relational themes and expressive displays of eight positive emotions.

Understanding positive emotions' shared and differentiating features can yield valuable insight into the structure of positive emotion space and identify emotion states, or aspects of emotion states, that are most relevant for particular psychological processes and outcomes. We report two studies that examined core relational themes (Study 1) and expressive displays (Study 2) for eight positive emotion constructs--amusement, awe, contentment, gratitude, interest, joy, love, and pride. Across studies, all eight emotions shared one quality: high positive valence. Distinctive core relational theme and expressive display patterns were found for four emotions--amusement, awe, interest, and pride. Gratitude was associated with a distinct core relational theme but not an expressive display. Joy and love were each associated with a distinct expressive display but their core relational themes also characterised pride and gratitude, respectively. Contentment was associated with a distinct expressive display but not a core relational theme. The implications of this work for the study of positive emotion are discussed.

Similarity, convergence, and relationship satisfaction in dating and married couples.

The current work investigates how personality and interpersonal processes combine to predict change in relationship quality. Measures of personality and emotion similarity were collected during laboratory interactions from a cross-sectional sample of dating couples (Study 1) and a 1-year longitudinal study of newlywed married couples (Study 2). Results showed that emotion similarity mediated the association between personality similarity and relationship quality (Studies 1 and 2) and that emotion convergence mediated the association between personality convergence and relationship satisfaction (Study 2). These results indicate that similarity and convergence in personality may benefit relationships by promoting similarity and convergence in partners' shared emotional experiences. Findings also lend support to models that integrate partners' enduring traits and couples' adaptive processes as antecedents of relationship outcomes.

Culture and teasing: the relational benefits of reduced desire for positive self-differentiation.

The authors hypothesized that teasing, a social interaction that benefits relational bonds at the expense of the self, should be viewed as more affiliative, and experienced as more pleasurable, by members of cultures that deemphasize positive self-differentiation. In four multimethod studies, Asian Americans attributed more affiliative intent to teasers and reported more positive target experience than did European Americans. Teaser behavior, attribution biases, and personality did not account for culture-related differences in teasing experience. Rather, childhood teasing may better prepare Asian American children to overlook a tease's affront to the self in favor of its relational rewards. Implications of deemphasizing positive self-differentiation in social interaction are discussed.

Relation of oxytocin to psychological stress responses and hypothalamic-pituitary-adrenocortical axis activity in older women.

OBJECTIVE: Animal research suggests that oxytocin (OT) plays a role in stress responses and that in females, this role is modulated by estrogen. Yet little is known about the relation of OT to human stress responses. This study was conducted to examine the relations between estrogen activity and OT, identify stressors distinctively associated with elevations in OT, and investigate whether OT is related to cardiovascular and hypothalamic-pituitary-adrenocortical (HPA) activity in a laboratory challenge paradigm. METHODS: Seventy-three postmenopausal women who were on hormone therapy (HT) or not completed questionnaires assessing psychological distress and social relationships and then participated in a laboratory stress challenge (Trier Social Stress Task), during which OT, cortisol, and blood pressure were assessed. RESULTS: HT was significantly associated with higher plasma OT. Controlling for HT, elevated plasma OT was significantly associated with gaps in social relationships, with less positive relationships with a primary partner, and with elevated cortisol levels. OT was not associated with stress reactivity or recovery. CONCLUSION: In women, plasma OT signals relationship stress and is associated with elevated cortisol; it does not appear to significantly affect cortisol or blood pressure responses to acute stress.

Will you be there for me when things go right? Supportive responses to positive event disclosures.

Close relationship partners often share successes and triumphs with one another, but this experience is rarely the focus of empirical study. In this study, 79 dating couples completed measures of relationship well-being and then participated in videotaped interactions in which they took turns discussing recent positive and negative events. Disclosers rated how understood, validated, and cared for they felt in each discussion, and outside observers coded responders' behavior. Both self-report data and observational codes showed that 2 months later, responses to positive event discussions were more closely related to relationship well-being and break-up than were responses to negative event discussions. The results are discussed in terms of the recurrent, but often overlooked, role that positive emotional exchanges play in building relationship resources.

Romantic love and sexual desire in close relationships.

Drawing on recent claims in the study of relationships, attachment, and emotion, the authors hypothesized that romantic love serves a commitment-related function and sexual desire a reproduction-related function. Consistent with these claims, in Study 1, brief experiences of romantic love and sexual desire observed in a 3-min interaction between romantic partners were related to distinct feeling states, distinct nonverbal displays, and commitment- and reproductive-related relationship outcomes, respectively. In Study 2, the nonverbal display of romantic love was related to the release of oxytocin. Discussion focuses on the place of romantic love and sexual desire in the literature on emotion.

Online dating across the life span: Users' relationship goals.

Utilizing data from an eHarmony.com relationship questionnaire completed by new users (N = 5,434), this study identifies prioritized goals in new romantic relationships and whether importance of these goals differs by participants' age and gender. Overall, users valued interpersonal communication more than sex appeal. Older users rated sexual attraction as slightly less important than younger users did, but they still highly valued the goal. Women placed even greater emphasis on communication over sexual attraction compared to men. However, although men valued sexual attraction more than women at all ages, only the youngest women valued interpersonal communication more than young men.

Effect of fresh fruit availability at worksites on the fruit and vegetable consumption of low-wage employees.

OBJECTIVE: To examine the impact of fresh fruit availability at worksites on the fruit and vegetable consumption and related psychosocial determinants of low-wage employees. DESIGN: A prospective, randomized block experimental design. SETTING: Seven apparel manufacturing and 2 food processing worksites. PARTICIPANTS: A convenience sample of 391 low-wage employees in 6 intervention worksites and 137 low-wage employees in 3 control worksites in Los Angeles, CA. INTERVENTION: Fresh fruit deliveries with enough for 1 serving per employee, 3 days a week for 12 consecutive weeks. The control worksites did not receive the fruit deliveries. MAIN OUTCOME MEASURES: Participants' fruit and vegetable consumption, fruit and vegetable purchasing habits, self-efficacy, job satisfaction, and overall health were measured at baseline, weeks 4 and 8, and following the 12-week intervention. ANALYSIS: Descriptive statistics and growth curve analysis using hierarchical linear modeling were employed to analyze the data. RESULTS: Participants in the intervention worksites showed a significant increase in fruit, vegetable, and total fruit and vegetable consumption, purchasing of fruit, family purchasing of vegetables, and self-efficacy toward eating 2 servings of fruit each day compared to the control worksites. CONCLUSIONS AND IMPLICATIONS: Improving access to fruit during the workday can improve fruit and vegetable consumption, purchasing habits, and self-efficacy of low-income employees.
