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. Across three studies, 459 romantic couples (N = 918), and various potentially stressful in-lab conversations (extra-dyadic problem, dislikes about each other, dependability, and relationship conflict), we found evidence that stress appraisals indicative of more challenge and less threat were associated with more approach- and less avoidance-oriented behaviors within interactions. These approach- and avoidance-oriented behaviors were associated with greater feelings of relationship security and well-being after the conversation. However, whose (actors or partners) appraisals and behaviors were associated with security and well-being varied across the three studies. This work provides theoretical and empirical evidence for an interpersonal emphasis on intraindividual stress appraisal processes through a dyadic and close relationships lens. Our integrative theoretical framework breaks away from the idea that stress is inherently “bad” or “maladaptive” to show that appraising stress as more manageable (more challenge, less threat) is associated with more relationship behaviors that approach incentives and less that avoid threats and enhance feelings of relationship security and well-being.

Higher resting heart rate variability (HRV)—an index of more flexible response to environmental stressors, including noxious stimuli—has been linked to reduced perception of experimentally induced pain. However, as stress responses are adapted to one’s chronic environments, we propose that chronic exposure to threats captured by one’s subjective socioeconomic status (SSS) may shape different adaptations that produce distinct pain responses linked to higher resting HRV. Specifically, lower SSS individuals with more threat exposures may prioritize threat detection by upregulating sensitivity to stressors, such as acute pain. Therefore, higher HRV would predict greater perceived acute pain among lower SSS individuals. In contrast, higher SSS individuals with less threat exposures may instead prioritize affective regulation by downregulating sensitivity to stressors, producing lower pain perception with higher HRV. We examined this stress response moderation by SSS in 164 healthy young adults exposed to experimental pain via the cold pressor test (CPT). Resting HRV, indexed by the root-mean-square of successive differences in heart rate, and self-reported SSS were measured at rest. Pain perception indexed by self-reported pain and pain tolerance indexed by hand-immersion time during the CPT were assessed. Results revealed that among higher SSS individuals, higher resting HRV predicted lower pain reports and subsequently greater pain tolerance during the CPT. Conversely, among lower SSS individuals, higher resting HRV predicted higher pain reports and subsequently lower pain tolerance. These findings provide preliminary evidence that environmental stress exposures linked to one’s SSS may shape unique biological adaptations that predict distinct pain responses.

A key limitation of studying emotion regulation behavior is that there is currently no way to describe individual differences in use across a range of tactics, which could lead to investigations of intraindividual changes over time or interindividual differences as a function of personality, age, culture, or psychopathology diagnosis. We, therefore, introduce emotion regulation convoys. This research tool provides a snapshot of the hierarchy of emotion regulation tactics an individual favors across everyday life situations and how effective they are at regulating moods. We present data from a 3-month measurement burst study of emotion regulation behavior in everyday life in a sample (N = 236) of younger (18–39), middle-aged (40–59), and older adults (60–87), focusing on how individuals’ convoys may vary in how much they include tactics that involve upregulating-positivity, downregulating-negativity, upregulating-negativity, as well as acceptance, and how these may be differentially effective. Among the most frequently used tactics (top tactics), older adults used a lower proportion of negativity-downregulating tactics than younger adults (p < .001), and younger adults’ mood was more negatively affected by these tactics than middle-aged and older adults. Overall, using positivity-upregulating as a top tactic also predicted better mood post-regulation. Older adults’ emotion regulation convoys may be made up of more effective tactics; in general, they reported more positive mood post-regulation than the other age groups. Convoys help us see emotion regulation as a hierarchical configuration of potentially effective behaviors, allowing us to test for between-group differences and within-person changes more precisely.

One foundational distinction in affective science is between emotion reactivity and regulation. This conceptual distinction has long been assumed to be instantiated in spatially separable brain systems (a typical example: amygdala/insula for reactivity and frontoparietal areas for regulation). In this research, we begin by reviewing previous findings that support and contradict the neural separability hypothesis concerning emotional reactivity and regulation. Further, we conduct a direct test of this hypothesis with empirical data. In five studies involving healthy and clinical samples (total n = 336), we assessed neural responses using fMRI while participants were asked to either react naturally or regulate their emotions (using reappraisal) while viewing emotionally evocative stimuli. Across five studies, we failed to find support for the neural separability hypothesis. In univariate analyses, both presumptive “reactivity” and “regulation” brain regions demonstrated equal or greater activation for the reactivity contrast than for the regulation contrast. In multivariate pattern analyses (MVPA), classifiers decoded reactivity (vs. neutral) trials more accurately than regulation (vs. reactivity) trials using multivoxel data in both presumptive “reactivity” and “regulation” regions. These findings suggest that emotion reactivity and regulation—as measured via fMRI—may not be as spatially separable in the brain as previously assumed. Our secondary whole-brain analyses revealed largely consistent results. We discuss the two theoretical possibilities regarding the neural separability hypothesis and offer thoughts for future research.

Engaging in a wide range of pleasant activities may provide mental health benefits, particularly for those genetically predisposed to depression. This study examined associations between pleasant activity variety, mental health, and genetic vulnerability in two U.S. cohort studies (N = 2,088). Participants reported depressive symptoms, mental healthcare visits, and engagement in pleasant activities over the past month. Greater variety of pleasant activities was associated with fewer depressive symptoms in both study samples. Individuals engaging in more diverse pleasant activities also had fewer mental health visits. Individuals with a higher genetic risk for depression experienced a stronger negative association between variety of pleasant activities and depressive symptoms compared to those with a lower genetic risk. These results highlight the potential of diverse pleasant activities as a means to enhance well-being, particularly among individuals genetically susceptible to depression.
