Article Synopsis
  • Ideal partner preferences shape key insights in human mating research, but recent studies face issues such as inconsistent analysis methods and varying findings across different populations.
  • A large-scale study involving 10,358 participants from 43 countries revealed significant effects of preference matching, particularly when analyzing traits collectively, with some traits showing minimal impact on partner evaluations.
  • The research also highlighted gender differences, where both men and women misjudged the importance of traits like attractiveness and earning potential in their stated preferences compared to actual revealed preferences.

Article Synopsis
  • This study investigates out-of-hospital cardiac arrest (OHCA) data in Türkiye, focusing on prognostic outcomes and influencing factors for patients aged 18 and older who were treated at 28 medical centers.
  • It found a survival rate upon hospital discharge of only 4.4%, with a significant majority of patients not receiving bystander CPR, which was only performed in 2.9% of cases.
  • Key predictors for better outcomes included male gender, initial shockable heart rhythms, shorter prehospital CPR duration, and no need for CPR in the emergency department, highlighting the importance of timely and effective CPR in emergencies.

Affective reactivity, defined as within-person increases in negative affect triggered by daily stressors, has well-established links to personal well-being. Prior work conceptualized affective reactivity as an intrapersonal phenomenon, reflecting reactions to one's own stressors. Here, we conceptualized reactivity interpersonally, examining one's responses to a daily stressors.

  • - The study compared standard rapid sequence intubation versus a rocuronium priming technique to assess their impact on procedure time and hemodynamic stability in emergency patients.
  • - Conducted with 52 patients, the results showed that the priming technique significantly reduced intubation time (68.4 seconds) compared to the standard method (121.2 seconds) and improved mean arterial pressure post-intubation.
  • - The findings indicate that using rocuronium priming enhances the efficiency of intubation while maintaining better hemodynamic stability.

Theoretical and empirical research on responsiveness focused mostly on cultural ecologies of independence. Emerging studies suggest that the responsiveness process may unfold differently in cultural ecologies of interdependence. We organize these studies into a working conceptual model.

Motivated by the Attachment Security Enhancement Model (Arriaga et al., 2018), the present research investigated the associations between positive relationship experiences and romantic attachment avoidance in three dyadic studies that combined multiple methods, including daily diaries, laboratory observations, and longitudinal follow-ups. Frequency of daily positive relationship events (but not external positive events) during a 21-day diary period predicted declines in romantic attachment avoidance (but not anxiety) from pre- to post-diary in fledgling couples (Study 1) and newlyweds (Study 2).

Increasing evidence suggests that heightened affective reactivity to daily stressors has implications for mental and physical health, yet little is known about the long-term repercussions of day-to-day stress reactivity for marital quality. This study examined associations between affective reactivity and two indicators of marital well-being (marital satisfaction and marital risk) over a 10-year period. An additional aim was to investigate the potential role of resting high-frequency heart rate variability (HF-HRV), an index of cardiac vagal regulation, in moderating the association between affective reactivity and marital quality.

Quality of marital relationships is consistently linked to personal well-being. However, almost all of the studies linking marital processes to well-being have been conducted in Western (particularly North American) countries. Growing evidence shows that perceived partner responsiveness is a central relationship process predicting well-being in Western contexts but little is known about whether this association generalizes to other countries.

Decades of research indicate that individuals adhere to existing states ("status quo bias") and value them more ("endowment effect"). The present work is the first to investigate status quo preference within the context of trade-offs in mate choice. Across seven studies (total N = 1,567), participants indicated whether they would prefer remaining with a current partner possessing a particular set of traits (e.

Past research on emotion regulation has provided evidence that cognitive reappraisal predicts reactivity to affective stimuli and challenge tests in laboratory settings. However, little is known about how trait reappraisal might contribute to affective reactivity to everyday positive and negative events. Using a large, life-span sample of adults (N = 1755), the present study addressed this important gap in the literature.

Motivated by attachment theory and recent conceptualizations of perceived partner responsiveness as a core feature of close relationships, the present study examined change in hedonic and eudaimonic well-being over a decade in a sample of more than 2,000 married adults across the United States. Longitudinal analyses revealed that perceived partner responsiveness- the extent to which individuals believe that their partner cares for, appreciates, and understands them-predicted increases in eudaimonic well-being a decade later. These results remained after controlling for initial hedonic and eudaimonic well-being, age, gender, extraversion, neuroticism, and perceived responsiveness of family and friends.

A defining feature of passionate love is idealization--evaluating romantic partners in an overly favorable light. Although passionate love can be expected to color how favorably individuals represent their partner in their mind, little is known about how passionate love is linked with visual representations of the partner. Using reverse correlation techniques for the first time to study partner representations, the present study investigated whether women who are passionately in love represent their partner's facial appearance more favorably than individuals who are less passionately in love.

Introduction: The end-tidal carbon dioxide (ETCO2) measurement was considered as an essential tool for the assessment of several conditions in emergency medicine. However, the diagnostic role of capnography in dyspneic patients still remains unclear. We aimed to analyze the alteration of the ETCO2 levels in chronic obstructive pulmonary disease (COPD) exacerbations and its role in the decision-making process.

Despite the simplicity of Kurzban et al.'s framework, we argue that important information is lost in their simplification. We discuss research on delay of gratification and self-regulation that identifies key situational and psychological factors affecting how people represent rewards and costs.

A growing literature shows that even the symbolic presence of an attachment figure facilitates the regulation of negative affect triggered by external stressors. Yet, in daily life, pernicious stressors are often internally generated--recalling an upsetting experience reliably increases negative affect, rumination, and susceptibility to physical and psychological health problems. The present research provides the first systematic examination of whether activating the mental representation of an attachment figure enhances the regulation of affect triggered by thinking about upsetting memories.
