Behavioral variability in physiological synchrony during future-based conversations between romantic partners.

Physiological synchrony-or similarity between two people's physiological responses-is thought to have important consequences for health and well-being and has been observed in social relationship contexts. The present study investigated variability in dyads' physiological synchrony as a function of both partners' behaviors during an emotionally salient discussion. We examined concurrent covariation in cardiac interbeat intervals in a sample of young adult romantic couples ( = 79 dyads) who discussed the coordination of a personal goal with the future of their relationship (data collected from 2013 to 2015).

Examining Dyadic Stress Appraisal Processes Within Romantic Relationships from a Challenge and Threat Perspective.

Unlabelled: The biopsychosocial model of challenge and threat emphasizes how individuals appraise stress. Close relationship theories emphasize the interpersonal context, communication, and outcomes that arise from stress. We integrate these approaches by examining the individual variability surrounding appraisals of sufficient (more challenge, less threat) or insufficient (more threat, less challenge) resources to cope with demands and examining how these appraisals are associated with couples' behavior and feelings toward each other.

Conflicting patterns of cardiovascular reactivity, self-report, and behavior associated with social anxiety during a conversation with a close friend.

Social anxiety (SA) is characterized by anxious symptomology and fear during social situations, but recent work suggests that SA may not necessarily be associated with negative interpersonal and intrapersonal outcomes in support contexts. The current research investigates the discrepancies between self-perceptions, behavior, and physiological responses associated with SA in social support conversations with close friends. Specifically, we examined the associations between SA and positive and negative affect, perceptions of demands and resources, and responsiveness.

Physiological synchrony in supportive discussions: An examination of co-rumination, relationship type, and heterogeneity.

During times of stress, we look to close others for support. Social support conversations are critical for relationship maintenance and well-being. Yet, certain ways of talking about problems-such as co-ruminating-can exacerbate stress.

"Let's go over it again": Examining the intra- and interpersonal processes that perpetuate co-rumination in close relationships.

Co-rumination is an interpersonal emotion regulation strategy characterized by extensive, cyclical conversations regarding the causes and consequences of problems and associated negative emotions. Theory posits that over time, interpersonal benefits of co-rumination such as emotional intimacy reinforce the behavior, outweighing the resulting negative impacts on mental health. However, our understanding of how co-rumination is perpetuated within conversations is limited.

Environmental DNA (eDNA) removal rates in streams differ by particle size under varying substrate and light conditions.

The use of environmental DNA (eDNA) as a sampling tool offers insights into the detection of invasive and/or rare aquatic species and enables biodiversity assessment without traditional sampling approaches, which are often labor-intensive. However, our understanding of the environmental factors that impact eDNA removal (i.e.

Suspended Materials Affect Particle Size Distribution and Removal of Environmental DNA in Flowing Waters.

Environmental DNA (eDNA) in aquatic systems is a complex mixture that includes dissolved DNA, intracellular DNA, and particle-adsorbed DNA. Information about the various components of eDNA and their relative proportions could be used to discern target organism abundance and location. However, a limited knowledge of eDNA adsorption dynamics and interactions with other materials hinders these applications.

Sense of power and markers of challenge and threat during extra-dyadic problem discussions with romantic partners.

Power, the capacity to influence others while resisting their attempts at influence, has implications for a wide variety of individual- and relationship-level outcomes. One potential mechanism through which power may be associated with various outcomes is motivation orientation. High power has been linked to greater approach-oriented motivation, whereas low power has been linked to greater avoidance-oriented motivation.

The intrapersonal and interpersonal consequences of a new experimental manipulation of co-rumination.

Co-rumination is a form of interpersonal emotion regulation wherein dyads engage in extensive, cyclical conversations regarding the causes and consequences of problems and associated negative emotions. In the present investigation, we leveraged the biopsychosocial model of challenge and threat to elucidate the intrapersonal costs and interpersonal benefits of co-rumination. To do so, we developed the first direct experimental manipulation of co-rumination using a multimethod, dyadic approach to test the effects of co-rumination on both dyad members.

Evil joy is hard to share: Negative affect attenuates interpersonal capitalizing on immoral deeds.

Capitalization is an interpersonal process in which individuals (capitalizers) communicate their accomplishments to others (responders). When these attempts to capitalize are met with enthusiastic responses, individuals reap greater personal and social benefits from the accomplishment. This research integrated the interpersonal model of capitalization with moral foundations theory to examine whether accomplishments achieved through immoral (vs.

When enhanced awareness threatens: Interactive effects of domain-specific awareness and acceptance manipulations on cardiovascular indices of challenge and threat.

Mindfulness includes acceptance and awareness subcomponents, and emerging theories imply that cultivating both acceptance and awareness may benefit health by diminishing stress reactivity. Yet, no prior work has examined the effects of mindful acceptance and awareness on cardiovascular markers of threat and challenge-cardiac output and total peripheral resistance-despite the unique insights these indices yield into stress-related evaluations and motivation. The current research integrates Monitor and Acceptance Theory with the Biopsychosocial Model of Challenge and Threat to elucidate how an awareness manipulation and a brief acceptance training are associated with cardiovascular stress responses underlying states of challenge and threat.

Attachment anxiety and the curvilinear effects of expressive suppression on individuals' and partners' outcomes.

Suppressing the expression of negative emotions tends to undermine individuals' and their partners' wellbeing. However, sometimes expressive suppression may be relatively innocuous given that individuals commonly withhold negative emotions in order to maintain close relationships, and this may be especially the case when expressive suppression is enacted by people who exhibit amplified expressions of negative emotions, such as those high in attachment anxiety. The current research examined when and for whom expressive suppression may be more or less costly by testing whether the curvilinear effect of individuals' expressive suppression on individuals' and partners' outcomes is moderated by individuals' attachment anxiety.

Anionic nanoparticle and microplastic non-exponential distributions from source scale with grain size in environmental granular media.

Nanoparticle and microplastic (colloid) transport behaviors impact strategies for groundwater protection and remediation. Complex colloid transport behaviors of anionic nano- and micro-sized colloids have been previously elucidated via independent experiments in chemically-cleaned and amended granular media with grain sizes in the range of fine to coarse sand (e.g.

Machine learning uncovers the most robust self-report predictors of relationship quality across 43 longitudinal couples studies.

Given the powerful implications of relationship quality for health and well-being, a central mission of relationship science is explaining why some romantic relationships thrive more than others. This large-scale project used machine learning (i.e.

Growing into retirement: Longitudinal evidence for the importance of partner support for self-expansion.

Retirement can be a turbulent time of life in which people must navigate changes in their identity from ending a career and beginning a new phase of life. However, retirement can also provide opportunities for growth or self-expansion. We examined the benefits of partner support for self-expansion by using longitudinal evidence (at 3 time points) in a sample of 73 couples.

The effects of dispositional restrictiveness on physiological markers of challenge and threat during a hypothetical transitional period in romantic relationships.

Restrictiveness, a component of relationship dominance associated with monitoring and regulating partners' behavior, is a risk factor and accelerant of Intimate Partner Violence (IPV). Few studies, however, have examined in vivo physiological responses associated with restrictiveness. Toward this end, 105 romantic couples (N = 210) completed measures of restrictiveness and had their physiological responses recorded in anticipation of and during a dyadic interaction in which they discussed a hypothetical transitional period in which one person (the discloser) revealed to their partner (the responder) that they had just gotten into their dream school or was offered their dream job.

Microbes and mental health: Can the microbiome help explain clinical heterogeneity in psychiatry?

Trillions of microbes cover the surfaces of our bodies and inhabit our gastrointestinal tract. In the past decade, research efforts examining the role of the microbiome in mental health have moved to the forefront of neuroscience and psychiatry. Based on a foundation of animal studies demonstrating the vital role for microbiota-brain communication in brain development, behavior, and brain function over the life span, clinical studies have started to consider the microbiome in psychiatric disorders.

Perceptions of romantic partners' emotional suppression are more biased than accurate.

The interpersonal consequences associated with emotional suppression (ES) may indicate that perceivers accurately detect targets' use of ES. However, ES involves hiding emotional experiences and expressions and consequently provides few explicit cues for perceivers. Thus, perceivers may exhibit relatively poor accuracy in detecting targets' ES and instead base perceptions of targets' ES on their own use of ES-a bias called projection.

Does expressing emotions enhance perceptual accuracy of negative emotions during relationship interactions?

Partners' negative emotions communicate social information necessary for individuals to respond appropriately to important relational events. Yet, there is inconsistent evidence regarding whether partners' emotional expression enhances accurate perceptions of partners' emotions. The current studies make methodological and theoretical extensions to the extant literature by directly assessing whether partners' emotional expression during relationship interactions predicts 2 types of accuracy relevant to the theorized interpersonal functions of negative emotions: tracking accuracy and directional bias.

Do habitual emotional suppression measures predict response-focused situational suppression during social interactions?

Greater habitual emotional suppression (ES)-assessed by the suppression subscale of the emotion regulation questionnaire (ERQ-ES; Gross & John, 2003) and the Courtauld emotion control scale (CECS; Watson & Greer, 1983)-is associated with a range of negative outcomes, which are assumed to arise because habitual ES measures capture the tendency to use ES in response to emotions. The current studies directly test whether habitual ES measures actually capture the response-focused use of ES when emotions arise within social interactions. We conduct these validation tests by integrating measures of habitual ES with naturalistic assessments of negative emotions and the situational use of ES during emotionally relevant interactions with romantic partners (Study 1, = 200; Study 3, = 170) and social interactions with close others in daily life (Study 2, = 430).

Habitat explains patterns of population decline for an invasive crayfish.

Invasive nonindigenous species are defined by their impacts: they substantially change native communities or ecosystems. Accordingly, invasive species might transform their habitats in ways that eventually become unfavorable to them, causing population declines or even extirpations. Here we use over 40 yr of systematically collected data on the abundance of the invasive rusty crayfish Faxonius rusticus from 17 lakes in northern Wisconsin, USA to explore whether population declines of this invader are related to the prevalence of rocky habitat, which shelters crayfish from predators and is unchanged by crayfish.

Cardiovascular indexes of threat impair responsiveness in situations of conflicting interests.

This research examined how situations in which self- and relationship-interests are misaligned can "get under the skin" to negatively impact cardiovascular and relationship processes. Interdependence theory was integrated with the biopsychosocial model of challenge and threat to better understand the biological processes that underlie relationship behavior in stressful circumstances. Couples engaged in a discussion in which one person (the discloser) revealed s/he had just gotten into her/his dream job or school and the other person (the responder) reacted to the news.

The consequences of having a dominant romantic partner on testosterone responses during a social interaction.

Testosterone reactivity has been conceptualized as a marker of social submission at low levels and social dominance at high levels. However, hormonal fluctuations in response to romantic partners remain largely unknown. Towards this end, 88 couples (N=176) discussed an emotional video.

The consequences of suppressing affective displays in romantic relationships: A challenge and threat perspective.

Emotion suppression is one of the most studied topics in emotion regulation. However, little is known about how response-focused regulation strategies unfold in romantic relationships from the perspectives of both emotion regulators and their interaction partners. Using the biopsychosocial (BPS) model of challenge and threat as an organizing framework, 2 experiments examined effects of expressive suppression (vs.
