Dispositional negativity in the wild: Social environment governs momentary emotional experience

Neuroticism/negative emotionality is associated with increased reactivity to uncertain threat in the bed nucleus of the stria terminalis, not the amygdala

Neuroticism/Negative Emotionality (N/NE)-the tendency to experience anxiety, fear, and other negative emotions-is a fundamental dimension of temperament with profound consequences for health, wealth, and wellbeing. Elevated N/NE is associated with a panoply of adverse outcomes, from reduced socioeconomic attainment to psychiatric illness. Animal research suggests that N/NE reflects heightened reactivity to uncertain threat in the bed nucleus of the stria terminalis (BST) and central nucleus of the amygdala (Ce), but the relevance of these discoveries to humans has remained unclear. Here we used a novel combination of psychometric, psychophysiological, and neuroimaging approaches to rigorously test this hypothesis in an ethnoracially diverse, sex-balanced sample of 220 emerging adults selectively recruited to encompass a broad spectrum of N/NE. Cross-validated robust-regression analyses demonstrated that N/NE is preferentially associated with heightened BST activation during the uncertain anticipation of a genuinely distressing threat (aversive multimodal stimulation), whereas N/NE was unrelated to BST activation during certain-threat anticipation, Ce activation during either type of threat anticipation, or BST/Ce reactivity to threat-related faces. It is often assumed that different threat paradigms are interchangeable assays of individual differences in brain function, yet this has rarely been tested. Our results revealed negligible associations between BST/Ce reactivity to the anticipation of threat and the presentation of threat-related faces, indicating that the two tasks are non-fungible. These observations provide a framework for conceptualizing emotional traits and disorders; for guiding the design and interpretation of biobank and other neuroimaging studies of psychiatric risk, disease, and treatment; and for informing mechanistic research.

Visualizing Compassion: Episodic Simulation as Contemplative Practice

Contemplative interventions designed to cultivate compassion are receiving increasing empirical attention. Accumulating evidence suggests that these interventions bolster prosocial motivation and warmth towards others. Less is known about how these practices impact compassion in everyday life. Here we consider one mechanistic pathway through which compassion practices may impact perception and action in the world: simulation. Evidence suggests that vividly imagining a situation simulates that experience in the brain as if it were, to a degree, actually happening. Thus, we hypothesize that simulation during imagery-based contemplative practices can construct sensorimotor patterns in the brain that prime an individual to act compassionately in the world. We first present evidence across multiple literatures in Psychology that motivates this hypothesis, including the neuroscience of mental imagery and the emerging literature on prosocial episodic simulation. Then, we examine the specific contemplative practices in compassion-based interventions that may construct such simulations. We conclude with future directions for investigating how compassion-based interventions may shape prosocial perception and action in everyday life.

Perceived emotion invalidation predicts daily affect and stressors

BACKGROUND AND OBJECTIVES

Perceived emotion invalidation is linked to the development or worsening of a variety of emotional and physical health conditions. However, prior studies are largely cross-sectional and whether there are day-to-day effects of generally feeling invalidated is unknown.

DESIGN

We examined the relations between perceived emotion invalidation and momentary affect, average daily affect, and the experience of daily stressors among a sample of young adults using ecological momentary assessment (EMA).

METHODS

Participants (n = 86) completed measures of perceived emotion invalidation and emotional reactivity at baseline then completed one week of EMA including: (1) 7x/day reports of current affect and social context and (2) 1x/day index of experienced stressors and their intensity.

RESULTS

Higher perceived emotion invalidation predicted lower momentary positive affect. Perceived invalidation also interacted with social context such that higher emotion invalidation predicted greater negative affect when participants were with non-close others (i.e., co-workers, acquaintances). Only participants with high perceived emotional invalidation experienced increased stress alongside heightened daily negative affect.

CONCLUSIONS

These results provide preliminary evidence that feeling emotionally invalidated may predict affective experiences, including how emotions are momentarily experienced and how life stressors are interpreted when they are later reflected on.

Individual differences in naturalistic learning link negative emotionality to the development of anxiety

Organisms learn from prediction errors (PEs) to predict the future. Laboratory studies using small financial outcomes find that humans use PEs to update expectations and link individual differences in PE-based learning to internalizing disorders. Because of the low-stakes outcomes in most tasks, it is unclear whether PE learning emerges in naturalistic, high-stakes contexts and whether individual differences in PE learning predict psychopathology risk. Using experience sampling to assess 625 college students' expected exam grades, we found evidence of PE-based learning and a general tendency to discount negative PEs, an "optimism bias." However, individuals with elevated negative emotionality, a personality trait linked to the development of anxiety disorders, displayed a global pessimism and learning differences that impeded accurate expectations and predicted future anxiety symptoms. A sensitivity to PEs combined with an aversion to negative PEs may result in a pessimistic and inaccurate model of the world, leading to anxiety.

Daily social interactions and momentary loneliness: The role of trait loneliness and neuroticism

OBJECTIVES

Loneliness has been linked to poor mental and physical health outcomes in later life. Little is known about how daily social interactions relate to older adults' everyday experiences of loneliness. This study examined the dynamic associations between social interactions and the momentary feelings of loneliness in older adults' daily lives. We further examined whether individual differences in trait loneliness and neuroticism influenced the extent to which daily social interactions were related to moment-to-moment change in loneliness.

METHOD

Participants were 317 community-dwelling older adults (aged 70-90 years) who reported their social interactions and momentary feelings of loneliness 5 times daily for 14 consecutive days using smartphones.

RESULTS

Having more frequent, more pleasant, and in-person social interactions, as well as interactions with family and friends specifically, significantly predicted lower momentary loneliness a few hours later. Higher levels of momentary loneliness, in turn, predicted less likelihood of engaging in these types of social interactions subsequently. In addition, older adults with higher (vs. lower) trait loneliness and neuroticism experienced greater decreases in momentary feelings of loneliness after having more frequent or pleasant social interactions, or interactions with family members.

DISCUSSION

These results expand our understanding of the dynamic associations between daily social interactions and loneliness in later life and provide insights to inform future research, including the possibility of behavioral interventions that target social interactions to reduce the risk for loneliness.

Anxiety-Related Frontocortical Activity Is Associated With Dampened Stressor Reactivity in the Real World

Negative affect is a fundamental dimension of human emotion. When extreme, it contributes to a variety of adverse outcomes, from physical and mental illness to divorce and premature death. Mechanistic work in animals and neuroimaging research in humans and monkeys have begun to reveal the broad contours of the neural circuits governing negative affect, but the relevance of these discoveries to everyday distress remains incompletely understood. Here, we used a combination of approaches-including neuroimaging assays of threat anticipation and emotional-face perception and more than 10,000 momentary assessments of emotional experience-to demonstrate that individuals who showed greater activation in a cingulo-opercular circuit during an anxiety-eliciting laboratory paradigm experienced lower levels of stressor-dependent distress in their daily lives (ns = 202-208 university students). Extended amygdala activation was not significantly related to momentary negative affect. These observations provide a framework for understanding the neurobiology of negative affect in the laboratory and in the real world.

The role of interpersonal perceptions of social inclusion and personality in momentary self-esteem and self-esteem reactivity

Empirical research has demonstrated that self-esteem is significantly shaped by social interactions and perceptions of social inclusion; however, less is known about individual differences in the reactivity of momentary self-esteem to social inclusion. Zooming into social interactions, we used data from two adolescent samples (overall N > 200) in two different social settings (i.e., a standardized laboratory interaction vs. real-life interactions) to examine the associations between different interpersonal perceptions (i.e., self-, other-, and metaperceptions) of social inclusion and momentary self-esteem. Further, we investigated how these associations are shaped by an individual’s personality (i.e., neuroticism, extraversion, and agreeableness). Multilevel modeling revealed differential associations between interpersonal perceptions and momentary self-esteem, with perceptions formed by the individual (i.e., self- and metaperceptions) more consistently related to momentary self-esteem than perceptions of others. Personality did not emerge as a consistent moderator of these associations but displayed differential effects: Neuroticism dampened self-esteem reactivity in group interactions with unfamiliar interaction partners, but not in dyadic interactions with familiar others. In light of these findings, we discuss the role of the social context and the interaction partner for the dynamic interplay of interpersonal perceptions and the functionality of personality traits.

Emotional Linkage as a Moderator of Emotional Reactivity Effect on Partners' Depressive Symptoms

Introduction: Romantic partners’ emotions show a degree of interdependence, a process that is often described as emotional linkage. The current study sought to test the effects of emotional linkage in emotionally reactive individuals (i.e., those who easily become emotionally aroused and find it hard to regulate their emotions) and their partners. Specifically, we examined the interplay between emotional linkage and reactivity in predicting partners’ depressive symptoms over time. Method: To assess emotional linkage and reactivity, we collected daily diary data from two samples of cohabiting couples (Ncouples=76 and 84 in samples 1 and 2, respectively). Partners’ depressive symptoms were assessed before and after the diary. Results: In dyads with low emotional linkage men's emotional reactivity predicted their greater depressive symptoms in Sample 1, and women's greater depressive symptoms in Sample 2. Discussion: The study's results suggest that dyads’ emotional linkage can moderate the negative effects of men's emotional reactivity on their and their partners’ psychological distress.

Extended-amygdala intrinsic functional connectivity networks: A population study

Pre-clinical and human neuroimaging research implicates the extended-amygdala (ExtA) (including the bed nucleus of the stria terminalis [BST] and central nucleus of the amygdala [CeA]) in networks mediating negative emotional states associated with stress and substance-use behaviours. The extent to which individual ExtA structures form a functionally integrated unit is controversial. We utilised a large sample (n > 1,000 healthy young adult humans) to compare the intrinsic functional connectivity networks (ICNs) of the BST and CeA using task-free functional magnetic resonance imaging (fMRI) data from the Human Connectome Project. We assessed whether inter-individual differences within these ICNs were related to two principal components representing negative disposition and alcohol use. Building on recent primate evidence, we tested whether within BST-CeA intrinsic functional connectivity (iFC) was heritable and further examined co-heritability with our principal components. We demonstrate the BST and CeA to have discrete, but largely overlapping ICNs similar to previous findings. We found no evidence that within BST-CeA iFC was heritable; however, post hoc analyses found significant BST iFC heritability with the broader superficial and centromedial amygdala regions. There were no significant correlations or co-heritability associations with our principal components either across the ICNs or for specific BST-Amygdala iFC. Possible differences in phenotype associations across task-free, task-based, and clinical fMRI are discussed, along with suggestions for more causal investigative paradigms that make use of the now well-established ExtA ICNs.

Do people with elevated social anxiety respond differently to digital and face-to-face communications? Two daily diary studies with null effects

BACKGROUND

Retrospective studies have found that people with elevated social anxiety (SA) show a preference for digital/online communication, which may be due to perceptions of enhanced emotional safety. Whether these individuals prefer digital compared to face-to-face communication and experience emotional benefits naturalistically remains unclear.

METHODS

We recruited college students (N = 125) and community adults (N = 303) with varying levels of SA and sampled their emotions during digital and face-to-face communication using ecological momentary assessment (EMA) (Study 1) and a day reconstruction method (DRM) (Study 2). We preregistered our hypotheses (https://osf.io/e4y7x/).

RESULTS

Results from both studies showed that SA did not predict the likelihood of engaging in digital compared to face-to-face communication, and SA was associated with less positive and more negative emotions regardless of the communication medium. Study 2 showed that whether digital communication was synchronous (e.g., in real time via phone/video chat) or asynchronous (e.g., texting/instant messaging) did not impact the association between SA and emotions.

LIMITATIONS

EMA and DRM methods, despite their many advantages, may be suboptimal for assessing the occurrence of digital communication behaviors relative to more objective methods (e.g., passively collecting smartphone communication data). Using event-contingent responding may have also yielded more reports of digital communication, thus strengthening our power to detect small, cross-level interaction effects.

CONCLUSIONS

These results challenge beliefs that digital/online communication provides a source of emotional safety for people with elevated SA and suggests a greater need to address SA-related emotional impairments across digital communication platforms.

Off-task thinking among adults with and without social anxiety disorder: an ecological momentary assessment study

Although task-unrelated thinking (often conceptualised as "mind-wandering") has been increasingly investigated in recent years, the content and correlates of everyday off-task thought in clinical disorders, particularly anxiety disorders, remain poorly understood. We aimed to address this gap by using ecological momentary assessment to assess off-task and on-task thoughts in adults with social anxiety disorder (SAD) and demographically matched controls. Findings showed that individuals with SAD more frequently engaged in internally oriented off-task thinking than healthy controls, but not externally oriented off-task thinking. Compared to thoughts focused on the task at hand, adults with SAD rated their internal off-task thoughts as less controllable, more self-focused, and as associated with worse mood than controls. However, when the SAD group was focused on the task at hand, group differences disappeared. Daily findings were paralleled by higher scores in SAD on a trait measure of unintentional, but not intentional, mind-wandering. In sum, the content and mood correlate of internally oriented off-task thoughts depended on the presence of clinical anxiety. In addition, focusing on the task at hand normalised thought content and mood in SAD, highlighting a window for intervention.

Anxiety and the Neurobiology of Temporally Uncertain Threat Anticipation

When extreme, anxiety-a state of distress and arousal prototypically evoked by uncertain danger-can be debilitating. Uncertain anticipation is a shared feature of situations that elicit signs and symptoms of anxiety across psychiatric disorders, species, and assays. Despite the profound significance of anxiety for human health and wellbeing, the neurobiology of uncertain-threat anticipation remains unsettled. Leveraging a paradigm adapted from animal research and optimized for fMRI signal decomposition, we examined the neural circuits engaged during the anticipation of temporally uncertain and certain threat in 99 men and women. Results revealed that the neural systems recruited by uncertain and certain threat anticipation are anatomically colocalized in frontocortical regions, extended amygdala, and periaqueductal gray. Comparison of the threat conditions demonstrated that this circuitry can be fractionated, with frontocortical regions showing relatively stronger engagement during the anticipation of uncertain threat, and the extended amygdala showing the reverse pattern. Although there is widespread agreement that the bed nucleus of the stria terminalis and dorsal amygdala-the two major subdivisions of the extended amygdala-play a critical role in orchestrating adaptive responses to potential danger, their precise contributions to human anxiety have remained contentious. Follow-up analyses demonstrated that these regions show statistically indistinguishable responses to temporally uncertain and certain threat anticipation. These observations provide a framework for conceptualizing anxiety and fear, for understanding the functional neuroanatomy of threat anticipation in humans, and for accelerating the development of more effective intervention strategies for pathological anxiety.SIGNIFICANCE STATEMENT Anxiety-an emotion prototypically associated with the anticipation of uncertain harm-has profound significance for public health, yet the underlying neurobiology remains unclear. Leveraging a novel neuroimaging paradigm in a relatively large sample, we identify a core circuit responsive to both uncertain and certain threat anticipation, and show that this circuitry can be fractionated into subdivisions with a bias for one kind of threat or the other. The extended amygdala occupies center stage in neuropsychiatric models of anxiety, but its functional architecture has remained contentious. Here we demonstrate that its major subdivisions show statistically indistinguishable responses to temporally uncertain and certain threat. Collectively, these observations indicate the need to revise how we think about the neurobiology of anxiety and fear.

Individual differences in fear acquisition: multivariate analyses of different emotional negativity scales, physiological responding, subjective measures, and neural activation

Negative emotionality is a well-established and stable risk factor for affective disorders. Individual differences in negative emotionality have been linked to associative learning processes which can be captured experimentally by computing CS-discrimination values in fear conditioning paradigms. Literature suffers from underpowered samples, suboptimal methods, and an isolated focus on single questionnaires and single outcome measures. First, the specific and shared variance across three commonly employed questionnaires [STAI-T, NEO-FFI-Neuroticism, Intolerance of Uncertainty (IU) Scale] in relation to CS-discrimination during fear-acquisition in multiple analysis units (ratings, skin conductance, startle) is addressed (NStudy1 = 356). A specific significant negative association between STAI-T and CS-discrimination in SCRs and between IU and CS-discrimination in startle responding was identified in multimodal and dimensional analyses, but also between latent factors negative emotionality and fear learning, which capture shared variance across questionnaires/scales and across outcome measures. Second, STAI-T was positively associated with CS-discrimination in a number of brain areas linked to conditioned fear (amygdala, putamen, thalamus), but not to SCRs or ratings (NStudy2 = 113). Importantly, we replicate potential sampling biases between fMRI and behavioral studies regarding anxiety levels. Future studies are needed to target wide sampling distributions for STAI-T and verify whether current findings are generalizable to other samples.

Social context and the real-world consequences of social anxiety

BACKGROUND

Social anxiety lies on a continuum, and young adults with elevated symptoms are at risk for developing a range of psychiatric disorders. Yet relatively little is known about the factors that govern the hour-by-hour experience and expression of social anxiety in the real world.

METHODS

Here we used smartphone-based ecological momentary assessment (EMA) to intensively sample emotional experience across different social contexts in the daily lives of 228 young adults selectively recruited to represent a broad spectrum of social anxiety symptoms.

RESULTS

Leveraging data from over 11 000 real-world assessments, our results highlight the central role of close friends, family members, and romantic partners. The presence of such close companions was associated with enhanced mood, yet socially anxious individuals had fewer confidants and spent less time with the close companions that they do have. Although higher levels of social anxiety were associated with a general worsening of mood, socially anxious individuals appear to derive larger benefits - lower levels of negative affect, anxiety, and depression - from their close companions. In contrast, variation in social anxiety was unrelated to the amount of time spent with strangers, co-workers, and acquaintances; and we uncovered no evidence of emotional hypersensitivity to these less-familiar individuals.

CONCLUSIONS

These findings provide a framework for understanding the deleterious consequences of social anxiety in emerging adulthood and set the stage for developing improved intervention strategies.

Moody and thin-skinned? The interplay of neuroticism and momentary affect in older romantic couples

Neuroticism is associated with heightened reactivity to social stressors. However, little is known about the micro-processes through which neuroticism shapes - and is shaped by - affective experiences in close relationships. We examine the extent to which momentary affect is coupled with one's relationship partner, whether the strength of this coupling differs depending on levels of neuroticism, and whether this coupling and partner's overall level of positive or negative affect prospectively contribute to differential (rank-order) changes in neuroticism. Older couples (N = 82, aged 67-93 years) rated their momentary affect six times per day for one week and provided ratings of trait neuroticism at baseline and 18 months later. Multilevel models revealed that among individuals high in neuroticism, individual positive affect was more closely coupled with partner positive affect compared with individuals low in neuroticism. Moreover, neuroticism decreased over time in those participants who showed a higher degree of coupling with partner positive affect and also had a partner with higher overall positive affect. In contrast, neuroticism increased in individuals whose partner had lower overall positive affect. Similar effects were not observed for negative affect. Our findings highlight how relationship partners contribute to daily affective experiences and longer-term changes in neuroticism.

The momentary benefits of positive events for individuals with elevated social anxiety

Understanding how individuals with varying levels of social anxiety respond to daily positive events is important. Psychological processes that increase positive emotions are being widely used as strategies to not only enhance well-being but also reduce the symptoms and impairment tied to negative emotional dispositions and conditions, including excessive social anxiety. At present, it is unclear whether and how levels of social anxiety impact the psychological benefits derived from momentary positive events. We used ecological momentary assessment to examine the impact of trait social anxiety on momentary changes in emotions, sense of belonging, and social approach versus avoidance motivation following positive events in daily life. Over the course of a week, people with elevated social anxiety experienced greater momentary anxiety and social avoidance motivation and lower momentary happiness and sense of belonging on average. Despite these impairments, individuals with elevated social anxiety experienced greater psychological benefits-in the form of reduced anxiety and motivation to avoid social situations, and an increased sense of belonging-following positive events during the past hour that were rated as particularly intense. This pattern of findings was not specific to social anxiety, with evidence of similar effects for other forms of internalizing psychopathology (general anxiety and depression). These observations detail circumstances in which individuals with social anxiety, and other emotional disturbances, can thrive-creating potentially important targets for intervention.

Dispositional negativity, cognition, and anxiety disorders: An integrative translational neuroscience framework

When extreme, anxiety can become debilitating. Anxiety disorders, which often first emerge early in development, are common and challenging to treat, yet the underlying mechanisms have only recently begun to come into focus. Here, we review new insights into the nature and biological bases of dispositional negativity, a fundamental dimension of childhood temperament and adult personality and a prominent risk factor for the development of pediatric and adult anxiety disorders. Converging lines of epidemiological, neurobiological, and mechanistic evidence suggest that dispositional negativity increases the likelihood of psychopathology via specific neurocognitive mechanisms, including attentional biases to threat and deficits in executive control. Collectively, these observations provide an integrative translational framework for understanding the development and maintenance of anxiety disorders in adults and youth and set the stage for developing improved intervention strategies.

The emotional brain: Fundamental questions and strategies for future research

Emotions play a central role in human experience. Over time, methods for manipulating emotion have become increasingly refined and techniques for making sense of the underlying neurobiology have become ever more powerful and precise, enabling new insights into the organization of emotions in the brain. Yet recent years have witnessed a remarkably vigorous debate about the nature and origins of emotion, with leading scientists raising compelling concerns about the canon of facts and principles that has inspired and guided the field for the past quarter century. Here, we consider ways in which recent neuroimaging research informs this dialogue. By focusing attention on the most important outstanding questions about the nature of emotion and the architecture of the emotional brain, we hope to stimulate the kinds of work that will be required to move the field forward. Addressing these questions is critical, not just for understanding the mind, but also for elucidating the root causes of many of its disorders.
