Culture and Awe: Understanding Awe as a Mixed Emotion.

Recent work is establishing awe as an important positive emotion that offers physical and psychological benefits. However, early theorizing suggests that awe's experience is often tinged with fear. How then, do we reconcile emergent positive conceptualizations of awe with its more fearful elements? We suggest that positive conceptualizations of awe may partially reflect modern Western experiences of this emotion, which make up the majority of participant samples when studying awe. To test whether awe contains more fearful qualities outside of Western cultures, we compared participants' experiences of this emotion in China to those in the United States. In a two-week daily diary study (Study 1), Chinese participants reported greater fear than American participants during experiences of awe, but not a comparison positive emotion. In response to a standardized awe induction (Study 2), Chinese participants reported more fear, whereas American participants reported more positive emotions. Physiological changes in autonomic activity differed by culture only for heart rate, but not skin conductance or respiratory sinus arrhythmia. These findings reveal that awe may be experienced as a more fearful, mixed emotion in China than in the United States and suggest that current positive conceptualizations of awe may reflect a disproportionate reliance on modern Western samples.

I love you but I hate your politics: The role of political dissimilarity in romantic relationships.

Amid heightened political polarization in the United States, have politics worked their way into the bedroom? An increase in political similarity between romantic partners has consequences not just for romantic relationships but for society as a whole; political homophily increases our political echo chambers and affects future generations. We drew upon 11 data sets with over 4,000 individuals (including more than 500 couples) to test four preregistered research questions about the prevalence, correlates, consequences, and potential buffers of political dissimilarity in modern-day relationships. Across measures of similarity (overall perceptions, partisanship matching, shared political ideology), couples in our sample showed high levels of political similarity (e.g., 23% were cross-partisan, with fewer than 8% composed of one Democrat and one Republican). Examining 18 potential correlates of political dissimilarity, we found little evidence that certain factors predispose people to end up in a politically dissimilar relationship. When considering the potential consequences of political dissimilarity, we found a small association between political dissimilarity and relationship quality in general and in daily life. The effect was evident when examining perceived political dissimilarity (over and above perceptions of overall similarity) and, to a lesser extent, dissimilarity in terms of partisanship and political ideology. Prosocial processes such as appreciation and perspective-taking may moderate these effects. Taken together, these findings speak to the need to further consider the ways in which the sociopolitical context is shaping the formation and maintenance of close relationships.

The Good, the Bad, and the Variable: Examining Stress and Blood Pressure Responses to Close Relationships.

Social relationships influence physical health, yet questions remain regarding the nature of this association. For instance, when it comes to predicting health-relevant processes in daily life, few studies have examined (a) the relative importance of both positive and negative relational experiences, and (b) variability in relational experiences (in addition to mean levels). To address these gaps, we conducted a daily study (N = 4,005; ~ 30,000 observations) examining relationships, stress, and physiology in daily life. Heart rate and blood pressure were assessed using an optic sensor and integrated with an app-based study. Results demonstrated that higher mean levels of positive and lower mean levels of negative relational experiences predicted lower stress, better coping, and better physiological functioning in daily life, such as lower systolic blood pressure reactivity. Greater variability in negative (but not positive) relational experiences predicted lower stress, better coping, and lower systolic blood pressure reactivity.

Stress reduction experiments in daily life: Scaling from the lab to the world.

Paced breathing-longer exhalation than inhalation-can show short-term improvement of physiologic responses and affective well-being, though most studies have relied on narrow sample demographics, small samples, and control conditions that fail to address expectancy effects. We addressed these limitations through an app-based experiment where participants were randomly assigned to paced breathing or sham control (hand closure) conditions. We first validated the conditions in an online sample (N = 201; Study 1) and in a lab environment (N = 72; Study 2). In the primary app-based experiment, participants (N = 3,277; Study 3) completed 3 days of baseline assessments that included three check-ins each day in which we obtained heart rate and blood pressure responses using an optic sensor and assessed current stress and emotions. Participants were then randomly assigned to either the paced breathing or hand closure condition for the next 6 days. Relative to baseline days, both conditions were associated with increased positive emotions and perceived coping, and reduced blood pressure. Moreover, the increase in positive emotions and perceived coping was not evident among a comparison sample (N = 2,600) who completed check-ins but did not participate in either of the paced breathing or sham-control conditions. However, their blood pressure declined over time, suggesting that the continual monitoring of one's blood pressure may result in detectable decreases. Our results highlight the importance of designing experiments with appropriately matched control conditions and suggest that changes associated with techniques like paced breathing, in part, may stem from positive incidental features of the technique.

Shared Hearts and Minds: Physiological Synchrony During Empathy.

Empathy is a multidimensional construct that includes changes in cognitive, affective, and physiological processes. However, the physiological processes that contribute to empathic responding have received far less empirical attention. Here, we investigated whether physiological synchrony emerged during an empathy-inducing activity in which individuals disclosed a time of suffering while their romantic partner listened and responded (N = 111 couples). Further, we examined the extent to which trait and state measures of cognitive and affective empathy were associated with each other and with physiological synchrony during this activity. We found evidence for physiological synchrony in skin conductance reactivity and also in interbeat interval reactivity, though only when disclosers were women, but not for respiratory sinus arrhythmia reactivity. Physiological synchrony was not consistently associated with other well-established trait and state measures of empathy. These findings identify the nuanced role of physiological synchrony in empathic responding to others' suffering.

Age Differences in Physiological Reactivity to Daily Emotional Experiences.

How does physiological reactivity to emotional experiences change with age? Previous studies addressing this question have mostly been conducted in laboratory settings during which emotions are induced via pictures, films, or relived memories, raising external validity questions. In the present research, we draw upon two datasets collected using ecological momentary assessment methods (totaling 134,723 daily reports from 14,436 individuals) to examine age differences in heart rate (HR) and blood pressure (BP) reactivity to naturally occurring emotional experiences. We first examined how older and younger individuals differ in the prevalence of emotions varying in valence and arousal. On average, people reported experiencing positive emotions (high or low arousal) more than 70% of the time they were asked, and older (vs. younger) individuals tended to report positive emotions more frequently. In terms of physiological reactivity, we found that age was associated with reduced HR and BP reactivity. Some evidence was also found that the magnitude of such age differences may depend on the valence or arousal of the experienced emotion. The present findings have implications for understanding how emotions can contribute to physical health across the lifespan.

Feeling understood and appreciated in relationships: Where do these perceptions come from and why do they matter?

Perceptions of romantic partners (even inaccurate perceptions) are important determinants of initial liking and long-term relationship satisfaction. In the current article, we consider the role of perceptions in romantic relationships through the lens of felt understanding and appreciation. We first examine where perceptions of feeling understood and appreciated come from, considering partner, self, and dyadic influences. We then examine how feeling understood and appreciated shape relationship quality, focusing on these perceptions as buffers of negative relationship experiences and mechanisms through which couples can create positive upward cycles of responsiveness and appreciation. Finally, we theorize about the unique dyadic experience of feeling understood and appreciated, positing that moments of mutual understanding and appreciation play a critical role in increasing social connection.

Daily Sleep Quality and Support in Romantic Relationships: The Role of Negative Affect and Perspective-Taking.

Sleep is an important predictor of social functioning. However, questions remain about how impaired sleep-which is common and detrimental to affective and cognitive functions necessary for providing high quality support-is linked to both the provision and perception of support, especially at the daily level. We tested links between impaired sleep and provided and perceived support in romantic couples, and whether these links were mediated by negative affect and perspective-taking. In preregistered analyses of two 14-day diary studies (Study 1 N = 111 couples; Study 2 N = 100 couples), poor daily subjective sleep quality-but not duration-was associated with less self-reported support toward a partner (in both studies), less perceived support from a partner and less partner-reported support (in Study 1), and partner perceptions of receiving less support (in Study 2). Only greater daily negative affect consistently mediated the association between participants' impaired sleep (i.e., poor subjective sleep quality and duration) and their own support provision, as well as their partner's perceptions of received support. Our findings suggest that the effect of sleep on social processes may be strongest for self-reported measures of support and that unique aspects of sleep might be differentially associated with social outcomes given that sleep quality-but not duration-was consistently linked to support outcomes. These findings highlight the psychosocial influences of sleep and negative affect, and may inform approaches to promote supportive partner interactions.

Acute and Chronic Stress Associations With Blood Pressure: An Ecological Momentary Assessment Study on an App-Based Platform.

OBJECTIVE: This study examined the within- and between-person associations of acute and chronic stress with blood pressure (BP) and heart rate (HR) using an app-based research platform. METHODS: We examined data from 31,964 adults (aged 18-90 years) in an app-based ecological momentary assessment study that used a research-validated optic sensor to measure BP. RESULTS: Within-person associations revealed that moments with (versus without) acute stress exposure were associated with higher systolic (SBP; b = 1.54) and diastolic BP (DBP; b = 0.79) and HR ( b = 1.53; p values < .001). During moments with acute stress exposure, higher acute stress severity than usual was associated with higher SBP ( b = 0.26), DBP ( b = 0.09), and HR ( b = 0.40; p values < .05). During moments without acute stress, higher background stress severity than usual was associated with higher BP and HR (SBP: b = 0.87, DBP: b = 0.51, HR: b = 0.69; p values < .001). Between-person associations showed that individuals with more frequent reports of acute stress exposure or higher chronic stress severity had higher SBP, DBP, and HR ( p values < .05). Between-person chronic stress severity moderated within-person physiological responses to stress such that individuals with higher chronic stress severity had higher average BP and HR levels but showed smaller responses to momentary stress. CONCLUSIONS: Technological advancements with optic sensors allow for large-scale physiological data collection, which provides a better understanding of how stressors of different timescales and severity contribute to momentary BP and HR in daily life.

Examining Daily Associations Among Sleep, Stress, and Blood Pressure Across Adulthood.

BACKGROUND: Sleep can have consequential effects on people's health and well-being, and these effects may vary among younger and older adults. PURPOSE: The goal of the present study was to investigate how sleep relates to physiologic and stress responses in daily life across adulthood. METHODS: We used an Ecological Momentary Assessment method in a large sample of participants (N = 4,359; Mage = 46.75, SD = 12.39; 69.30% male, 29.85% female) who completed morning sleep diaries, reported subjective stress, and recorded their heart rate and blood pressure for 21 days. Sleep was assessed with self-reports of duration, efficiency, and quality. RESULTS: Using multilevel modeling, between-person analyses showed that sleep duration, efficiency, and quality were negatively related to morning heart rate and stress, such that people who slept longer, more efficiently, or better experienced lower heart rate and stress compared to those who slept shorter, less efficiently, or worse. Within-person analyses showed that sleep duration, efficiency, and quality predicted morning heart rate, blood pressure (though less consistently), and stress. That is, people experienced lower heart, blood pressure, and stress following nights when they slept longer, more efficiently, or better than they typically did. These within-person relationships were moderated by age, such that the effects of better and longer sleep on lower morning heart rate, blood pressure, and stress were stronger among younger than older adults. CONCLUSION: These findings suggest that daily variations in sleep show immediate associations with stress and physiologic responses, but these daily variations have a stronger relationship among younger compared to older adults.

We examined how sleep influences people's blood pressure and well-being among younger and older adults. Participants (N = 4,359) completed questionnaires in the morning over the course of 21 days and reported how well and how long they slept that night and how stressed they felt. They also recorded their heart rate and blood pressure using an optic sensor on their phones. Our analyses showed that people who slept longer, more efficiently, or better experienced lower levels of heart rate and stress on average compared to those who slept shorter, less efficiently, or worse. In addition, we examined how changes in sleep influenced stress, heart rate, and blood pressure for a given individual. These analyses showed that people experienced lower heart rate, lower blood pressure, and less stress following nights when they slept longer, more efficiently, or better than they typically did. These relationships varied by age such that the beneficial effects of sleep were more pronounced among younger than older adults. That is, receiving a particularly good night of sleep tends to be beneficial for younger adults, whereas older adults may not be influenced as strongly by the quality and duration of their sleep.

Indirect associations between infant sleep, parental sleep, and sexual well-being in new parent couples.

New parents' sexual frequency and desire fluctuate throughout the transition to parenthood (i.e., the first year after childbirth). Poorer infant sleep and parental sleep are each associated with lower sexual frequency and desire in cross-sectional research. According to the theory, infant sleep might shape new parents' sexual frequency and desire in so far as it disrupts parental sleep, though this pathway has yet to be examined. We examined the role of parental sleep in the indirect pathway between infant sleep and sexual frequency and sexual desire in couples, both within and between-person, during the first-year postpartum. In a dyadic longitudinal study, 203 first-time mothers and their partners reported on infant sleep quality, parental sleep, sexual frequency, and sexual desire at 3-, 6-, 9-, and 12-months postpartum. Poorer infant sleep was associated with mothers' (within-couple) and partners' (between-couple) poorer sleep and, in turn, lower sexual frequency for the couple. For both mothers (within-person) and partners (between-person), poorer infant sleep was associated with their own lower sexual desire through poorer parental sleep via the indirect pathway. Ongoing assessment of infant sleep and parental sleep may reveal opportunities to mitigate the negative effects of poor sleep on new parents' sexual relationships.

Sleep, Emotions, and Sense of Belonging: A Daily Experience Study.

Sleep has strong influences on affective and social experiences. However, less is known about the reciprocal effects of sleep, affect, and social experiences at a daily level, and little work has considered racial/ethnic minorities at high risk for social disconnection and discrimination. A 7-day daily experience study assessed the bidirectional relationships between daily sleep quality, affect, social experiences, and overall well-being among a sample of Latinx undergraduates (N = 109). Each morning, participants reported on their previous night's sleep. Each evening, they reported their positive and negative affect, experiences of belonging and unfair treatment, and overall well-being that day. Results indicate that, at a daily level, sleep quality predicts next-day affect, belonging, and well-being. Reciprocally, only daily well-being predicts sleep quality. Findings highlight sleep as a potentially powerful antecedent of affective and social experiences likely to be particularly potent for underrepresented minority groups.

Feeling Appreciated Buffers Against the Negative Effects of Unequal Division of Household Labor on Relationship Satisfaction.

Decades of research from across the globe highlight unequal and unfair division of household labor as a key factor that leads to relationship distress and demise. But does it have to? Testing a priori predictions across three samples of individuals cohabiting with a romantic partner during the COVID-19 pandemic (N = 2,193, including 476 couples), we found an important exception to this rule. People who reported doing more of the household labor and who perceived the division as more unfair were less satisfied across the early weeks and ensuing months of the pandemic, but these negative effects disappeared when people felt appreciated by their partners. Feeling appreciated also appeared to buffer against the negative effects of doing less, suggesting that feeling appreciated may offset the relational costs of unequal division of labor, regardless of who contributes more. These findings generalized across gender, employment status, age, socioeconomic status, and relationship length.

Comparing daily physiological and psychological benefits of gratitude and optimism using a digital platform.

Gratitude and optimism are positive psychological dispositions associated with beneficial outcomes. To examine their associations with physiological and psychological experiences in daily life, we examined data from an Ecological Momentary Assessment study (N = 4,825), including blood pressure, heart rate, and reports of stress, health behaviors, and thoughts. Trait gratitude and trait optimism both predicted lower heart rate and blood pressure, better sleep quality, more exercise, less stress, more positive expectations and reflections, and greater feelings of appreciation toward others. However, gratitude and optimism were not completely overlapping constructs: Gratitude was a stronger predictor of felt appreciation toward others and pleasantness when reflecting on the best part of the day, whereas optimism was a stronger predictor of sleep quality, lower stress, and lower unpleasantness when reflecting on the worst part of the day. These associations reveal both similar and differential influences of positive dispositions on psychological and physiological outcomes that provide insight into health consequences.

A large-scale study of stress, emotions, and blood pressure in daily life using a digital platform.

Stress is often associated with pathophysiologic responses, like blood pressure (BP) reactivity, which when experienced repeatedly may be one pathway through which stress leads to poor physical health. Previous laboratory and field studies linking stress to physiological measures are limited by small samples, narrow demographics, and artificial stress manipulations, whereas large-scale studies often do not capture measures like BP reactivity in daily life. We examined perceived stress, emotions, heart rate, and BP during daily life using a 3-wk app-based study. We confirmed the validity of a smartphone-based optic sensor to measure BP and then analyzed data from more than 330,000 daily responses from over 20,000 people. Stress was conceptualized as the ratio of situational demands relative to individual resources to cope. We found that greater demands were associated with higher BP reactivity, but critically, the ratio of demands relative to resources improved prediction of BP changes. When demands were higher and resources were lower, there was higher BP reactivity. Additionally, older adults showed greater concordance between self-reported stress and physiologic responses than younger adults. We also observed that physiologic reactivity was associated with current emotional state, and both valence and arousal mattered. For example, BP increased with high-arousal negative emotions (e.g., anger) and decreased with low-arousal positive emotions (e.g., contentment). Taken together, this work underscores the potential for expanding stress science and public health data using handheld phones to reliably and validly measure physiologic responses linked to stress, emotion, and physical health.

Sleep and social relationships in healthy populations: A systematic review.

Over the past decade, research linking sleep and social relationships has burgeoned. Researchers across the globe are trying to understand whether the quality and quantity of our social relationships matter for sleep, and vice versa. We conducted a systematic review of the literature, identifying over 200 relevant articles examining sleep and social relationships in healthy populations. Here, we summarize our findings by reviewing 1) links between sleep and broad social ties across the lifespan, and 2) links between sleep and specific social relationships identified in the literature search, including romantic relationships, family relationships, and work relationships. Taken together, the literature provides evidence that the quality and presence of social relationships, especially our closest relationships, play a role in how we sleep. Likewise, sleep appears to influence our social bonds. However, the majority of work is correlational, limiting conclusions about the directionality of these effects. We conclude by synthesizing the findings, considering the limitations of the present literature, and identifying key future directions for this emerging area of research.

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., Random Forests) to 1) quantify the extent to which relationship quality is predictable and 2) identify which constructs reliably predict relationship quality. Across 43 dyadic longitudinal datasets from 29 laboratories, the top relationship-specific predictors of relationship quality were perceived-partner commitment, appreciation, sexual satisfaction, perceived-partner satisfaction, and conflict. The top individual-difference predictors were life satisfaction, negative affect, depression, attachment avoidance, and attachment anxiety. Overall, relationship-specific variables predicted up to 45% of variance at baseline, and up to 18% of variance at the end of each study. Individual differences also performed well (21% and 12%, respectively). Actor-reported variables (i.e., own relationship-specific and individual-difference variables) predicted two to four times more variance than partner-reported variables (i.e., the partner's ratings on those variables). Importantly, individual differences and partner reports had no predictive effects beyond actor-reported relationship-specific variables alone. These findings imply that the sum of all individual differences and partner experiences exert their influence on relationship quality via a person's own relationship-specific experiences, and effects due to moderation by individual differences and moderation by partner-reports may be quite small. Finally, relationship-quality change (i.e., increases or decreases in relationship quality over the course of a study) was largely unpredictable from any combination of self-report variables. This collective effort should guide future models of relationships.

Anticipated and Experienced Ethnic/Racial Discrimination and Sleep: A Longitudinal Study.

The transition to college is a stressful experience. For members of underrepresented minority groups, the usual stresses are frequently accompanied by ethnicity-based stressors, including discrimination. This longitudinal study extends prior work on discrimination by examining the prospective associations between anticipated and experienced ethnic/racial discrimination and sleep, a ubiquitous and basic biological need critical for optimal functioning. In a sample of 274 low-income/first-generation Latinx students, results from a cross-lagged panel model revealed that both the anticipation and experience of discrimination at the beginning of college uniquely predicted worsening sleep quality over the second half of freshmen year, controlling for relevant covariates. There was also some evidence for bidirectionality, with poor sleepers experiencing more discrimination. These findings add to the literature linking discrimination and sleep, both of which play large roles in mental, physical, social, and academic outcomes.

Bidirectional Links Between Social Rejection and Sleep.

OBJECTIVE: This set of studies examines the bidirectional links between social rejection and poor sleep, a ubiquitous and increasingly problematic health behavior. METHODS: In study 1, a multiday field experiment, 43 participants completed a neutral task just before sleep on night 1 and a social rejection task on night 2. Objective and subjective sleep, postrejection affect, and physiological responses were measured. In study 2, 338 participants reported typical sleep quality before coming to the laboratory where they received social rejection or social acceptance feedback from a stranger. Physiological and affective responses were measured throughout the session. RESULTS: In study 1, after social rejection, participants took longer going to bed (M [SD] = 38.06 [48.56] versus 11.18 [15.52], t(42) = 3.86, p < .001) and had shorter sleep durations (6:46 [1:27] versus 7:19 [1:38], t(41) = 2.92, p = .006) compared with the baseline night. Trait rumination moderated these effects, with high ruminators taking the longest to go to bed postrejection (t(38) = 2.90, p = .006). In both studies, there was (inconsistent) evidence that sleep influences reactions to rejection: some sleep measures predicted physiological reactivity during the rejection task in study 1 and greater negative affect after social rejection in study 2. CONCLUSIONS: These studies provide evidence that social rejection may affect sleep outcomes, particularly for trait ruminators, and poor sleep in turn may exacerbate affective responses to social rejection. Given the mixed findings, small sample size, and no active control condition, more work is needed to confirm and build on these findings.

Awe and humility.

Humility is a foundational virtue that counters selfish inclinations such as entitlement, arrogance, and narcissism (Tangney, 2000). We hypothesize that experiences of awe promote greater humility. Guided by an appraisal-tendency framework of emotion, we propose that when individuals encounter an entity that is vast and challenges their worldview, they feel awe, which leads to self-diminishment and subsequently humility. In support of these claims, awe-prone individuals were rated as more humble by friends (Study 1) and reported greater humility across a 2-week period (Study 2), controlling for other positive emotions. Inducing awe led participants to present a more balanced view of their strengths and weaknesses to others (Study 3) and acknowledge, to a greater degree, the contribution of outside forces in their own personal accomplishments (Study 4), compared with neutral and positive control conditions. Finally, an awe-inducing expansive view elicited greater reported humility than a neutral view (Study 5). We also elucidated the process by which awe leads to humility. Feelings of awe mediated the relationship between appraisals (perceptions of vastness and a challenge to one's world view) and humility (Study 4), and self-diminishment mediated the relationship between awe and humility (Study 5). Taken together, these results reveal that awe offers one path to greater humility. (PsycINFO Database Record
