Need Fulfillment and Stay-Leave Behavior: On the Diagnosticity of Personal and Relational Needs.

Need fulfillment has been found to be associated with numerous positive relationship outcomes, but its impact on stay–leave behavior is less clear. In the current study, we considered whether the fulfillment of different needs might differentially affect stay–leave behavior. We distinguished between needs that are personal in nature and those that are relational in nature. Central to our theoretical analysis is the interdependence-based contention that the fulfillment of different kinds of needs provides diagnostic information regarding a partner’s motives and intentions regarding a relationship. Using two-wave longitudinal data obtained from romantically involved participants, we tested the relative fit of two alternative models that specified the associations between the fulfillment of different kinds of needs, commitment, and stay–leave behavior. Consistent with an interdependence approach, we found that the influence of the fulfillment of personal needs on stay–leave behavior was mediated by commitment, whereas the fulfillment of relational needs directly influenced stay–leave behavior. Implications for relationship functioning are considered

Peer Influence and Attraction to Interracial Romantic Relationships

The present research examined the effect of social influence on White, heterosexual individuals’ attraction to targets of varying races (White vs. Black) in two college student samples from the United States (one that leaned politically liberal and one that leaned politically conservative). Using a within-subjects experimental design, participants were given artificial peer evaluation data (positive, negative, or none) before providing ratings of attractiveness and dating interest for a series of targets. In both samples, positive information was associated with greater levels of attraction and dating interest than negative information, regardless of target race. Within the conservative sample, participants reported greater attraction toward and more dating interest in White targets relative to Black targets, while in the liberal sample, participants’ ratings of targets did not significantly differ from one another. These findings suggest that social influence can affect perceptions of attractiveness even in very different political climates.Psycholog

Chemiosmotic Coupling in Methanobacterium thermoautotrophicum:Hydrogen-Dependent Adenosine 5'-Triphosphate Synthesis by Subcellular Particles

Hydrogenase and the adenosine 5'-triphosphate (ATP) synthetase complex, two enzymes essential in ATP generation in Methanobacterium thermoautotrophicum, were localized in internal membrane systems as shown by cytochemical techniques. Membrane vesicles from this organism possessed hydrogenase and adenosine triphosphatase (ATPase) activity and synthesized ATP driven by hydrogen oxidation or a potassium gradient. ATP synthesis depended on anaerobic conditions and could be inhibited in membrane vesicles by uncouplers, nigericin, or the ATPase inhibitor N,N'-dicyclohexylcarbodiimide. The presence of an adenosine 5'-diphosphate-ATP translocase was postulated. With fluorescent dyes, a membrane potential and pH gradient were demonstrated

On the Benefits of Valuing Being Friends for Non-Marital Romantic Partners

Romantic relationships are, at their core, friendships. As such, it may be the case that valuing that aspect of the relationship fortifies the romantic relationship against negative outcomes and serves as a buffer against dissolution. We explored the role of valuing friendship within romantic relationships in two two-wave studies examining whether investing in the friendship aspect of the relationship (Study 1; N = 190) and placing importance on affiliative need fulfillment (Study 2; N = 184) were associated with positive concurrent outcomes and positive outcomes over time. Results revealed that valuing the friendship aspect of a romance is a strong positive predictor of concurrent romantic relationship qualities (i.e., love, sexual gratification, and romantic commitment), is associated with increases in these qualities over time and is negatively associated with romantic dissolution. Furthermore, evidence suggests that these benefits come from valuing friendship specifically, rather than any other aspect of the relationship (e.g., the sexual aspect)

Whose Intentions Predict? Power over Condom Use within Heterosexual Dyads

According to major theories of behavioral prediction, the most proximal psychological predictor of an individual’s behavior is that individual’s intention. With respect to interdependent behaviors such as condom use, however, relationship dynamics influence individuals’ power to make decisions and to act. Objective: The current study examines how relationship dynamics impact 3 condom use relevant outcomes: (a) the individual forming his or her own intention to use condoms, (b) the couple forming their joint intention to use condoms, and (c) actual condom use behavior. Method: We conducted a 2-wave longitudinal study of young heterosexual adult couples at high risk for HIV infection involving the collection of both individual- and couple-derived data. Results: Results demonstrate the importance of both person (e.g., biological sex and dispositional dominance) and relational (e.g., relational power and amount of interest in the relationship, operationalized as commitment and perceived alternatives to the relationship) factors in predicting condom use intentions and behavior. Individuals who are lower in dispositional dominance are likely to incorporate their partner’s intentions into their own individual intentions; the intentions of individuals who have less interest in the relationship are more highly predictive of the couple’s joint intention; and the intentions of men and individuals higher in relationship power are more likely to exert a direct influence on condom use. Conclusions: These findings have implications for improving the health of high-risk individuals, including suggesting situations in which individuals are highly influenced by their partners’ intentions

Examining affective-motivational dynamics and behavioral implications within the interpersonal context of pain

Emotional, motivational, and interpersonal dimensions are considered integral to pain experience but have largely been examined separately. In this focus article, we argue that an integrative theoretical account that acknowledges each of these elements is a critical next step to capture the complexity and nuance of interpersonal pain dynamics and to shape future research. The aim of this focus article is to provide a foundation for such an account by drawing upon established insights from appraisal theory of emotion, influential behavioral models, empathy/interpersonal pain research, and social psychology literature to highlight conceptual relationships, potential mechanisms of action, and avenues of inquiry that have not previously been examined in the context of pain. Specifically, we highlight the interpersonal nature of pain and the conceptual relationship between emotion and motivation in pain experience. We discuss an affective-motivational tension between self- and other-oriented goals that can arise within the interpersonal pain context, and how such dynamics may affect the nature and effectiveness of care giving behavior. We then describe the role of emotion regulation and strategies that may facilitate optimal interpersonal pain dynamics and caregiving within a multiple goal context. Finally, we outline a foundation for an integrative theoretical model and directions for future research. Perspective: Drawing upon insights from appraisal theory of emotion, empathy/interpersonal pain research, influential behavioral models, and social psychology literature, this focus article provides a foundation for an integrative affective-motivational account of interpersonal pain dynamics as a basis for theoretical and clinical advancement.

The “I” in us, or the eye on us? Regulatory focus, commitment and derogation of an attractive alternative person

When individuals are highly committed to their romantic relationship, they are more likely to engage in pro-relationship maintenance mechanisms. The present research expanded on the notion that commitment redirects self-oriented goals to consider broader relational goals and examined whether commitment interacts with a promotion and prevention focus to activate derogation of attractive alternatives. Three studies used cross-sectional and experimental approaches. Study 1 showed that romantically involved individuals predominantly focused on promotion, but not prevention, reported less initial attraction to an attractive target than single individuals, especially when highly committed to their relationship. Study 2 showed that romantically involved individuals induced in a promotion focus, compared to those in prevention focus, reported less initial attraction, but only when more committed to their relationship. Regardless of regulatory focus manipulation, more committed individuals were also less likely to perceive quality among alternative scenarios and to be attentive to alternative others in general. Finally, Study 3 showed that romantically involved individuals induced in promotion focus and primed with high commitment reported less initial attraction, than those primed with low commitment, or than those induced in prevention focus. Once again, for these latter no differences occurred according to commitment prime. Together, the findings suggest that highly committed promotion focused individuals consider broader relationship goals and activate relationship maintenance behaviors such as derogation of attractive alternatives to promote their relationship

The relational consequences of personal goal pursuits

In daily life, individuals must balance the tasks necessary to fulfill goals spanning several domains of life. In the current studies, we examined what impact ongoing personal goal pursuits have on how individuals attend to and process information relevant to relational goals. In four experiments, we employed a manipulation that evokes the cognitive tuning and biased processing associated with the mindsets that arise naturally during goal striving (Gollwitzer, 1990), and examined the consequences of these mindsets for the relationship. Results indicated that when an individual focused on pursuing a personal goal, they failed to attend to their relational goals (Study 1), were unwilling to engage in pro-relationship behavior that incurred cost for the personal goal (Study 2), and processed their relational goal achievement in a one-sided (i.e., without nuance or variability; Study 3), evaluatively polarized (Study 4) fashion. Together, these findings provide a greater understanding of how pursuing a personal goal can undermine relationship maintenance
