The role of perceived negative partner behavior in daily snacking behavior: A dynamical systems approach.

Past work suggested that psychological stress, especially in the context of relationship stress, is associated with increased consumption of energy-dense food and when maintained for long periods of time, leads to adverse health consequences. Furthermore, this association is moderated by a variety of factors, including emotional over-eating style. That being said, few work utilized a dynamical system approach to understand the intraindividual and interindividual fluctuations within this process.

Perspectives of School Leaders on Supporting Learners With Special Education Needs During the COVID-19 Pandemic: An Ethic of Care Analysis.

The ethic of care is a moral philosophy that has been used to describe and guide the work of educators, especially those working with students with special education needs (SEN). In this study, 36 principals and vice principals from four provinces in Canada were interviewed about their work with students with SEN during the pandemic. Responses were analyzed using the ethic of care framework.

Interoceptive beliefs moderate the link between physiological and emotional arousal during an acute stressor.

Growing work suggests that interoception, that is, representations of one's internal bodily changes, plays a role in shaping emotional experiences. Past studies primarily examine how behavioral accuracy in detecting interoceptive signals ) relates to emotional states, with less work examining self-reported interoceptive facets such as the characterizations of one's interoceptive abilities () or evaluative beliefs about the value versus danger of interoceptive signals ). However, existing studies rarely examine physiological reactivity, behavioral, and self-reported dimensions of interoception together in the same sample.

Interoceptive ability moderates the effect of physiological reactivity on social judgment.

Social judgments-that others are kind or cruel, well intentioned, or conniving-can ease or disrupt social interactions. And yet a person's internal state can alter these judgments-a phenomenon known as . We examined the factors that contribute to, and mitigate, affective realism during a stressful interview.

The impact of sociality and affective valence on brain activation: A meta-analysis.

Thirty years of neuroimaging reveal the set of brain regions consistently associated with pleasant and unpleasant affect in humans-or the neural reference space for valence. Yet some of humans' most potent affective states occur in the context of other humans. Prior work has yet to differentiate how the neural reference space for valence varies as a product of the sociality of affective stimuli.

Psychophysiological and affective reactivity to vicarious police violence.

Little is known about how vicarious police violence, or instances of police violence observed but not directly experienced, impacts health among Black individuals. Using a lab-based paradigm in a sample of young adults (N = 101), this study examined: (a) psychophysiological reactivity to instances of vicarious police violence, particularly the assault and shooting of Black individuals; (b) affective reactivity to instances of vicarious police violence; and (c) how racial identity, one important moderator, influences psychophysiological and affective responses to vicarious police violence. Using electrocardiography and impedance cardiography, participants' cardiac sympathetic and parasympathetic physiological responses were continuously monitored.

The affective harm account (AHA) of moral judgment: Reconciling cognition and affect, dyadic morality and disgust, harm and purity.

Moral psychology has long debated whether moral judgment is rooted in harm versus affect. We reconcile this debate with the affective harm account (AHA) of moral judgment. The AHA understands harm as an intuitive perception (i.

Prosocial and Positive Health Behaviors During a Period of Chronic Stress Protect Socioemotional Well-Being.

Unlabelled: Behavior that helps, supports, or protects others-or prosocial behavior-has emerged as a health-relevant behavior that can promote the giver's well-being, yet whether prosocial behavior protects against the effects of a major, ongoing chronic stressor warrants further examination. Thus, in the context of the 2020 COVID-19 pandemic, we examined whether two types of behaviors-those enacted to prevent the spread of disease to the self and others (positive health behaviors) and those enacted to promote others' psychological and financial well-being (prosocial behaviors)-might protect well-being over time. Using a longitudinal survey method, 745 participants (  = 62.

β-Adrenergic Contributions to Emotion and Physiology During an Acute Psychosocial Stressor.

Objective: β-Adrenergic receptor signaling, a critical mediator of sympathetic nervous system influences on physiology and behavior, has long been proposed as one contributor to subjective stress. However, prior findings are surprisingly mixed about whether β-blockade (e.g.

Neurophysiological contributors to advantageous risk-taking: an experimental psychopharmacological investigation.

The ability to learn from experience is critical for determining when to take risks and when to play it safe. However, we know little about how within-person state changes, such as an individual's degree of neurophysiological arousal, may impact the ability to learn which risks are most likely to fail vs succeed. To test this, we used a randomized, double-blind, placebo-controlled design to pharmacologically manipulate neurophysiological arousal and assess its causal impact on risk-related learning and performance.

The neural underpinnings of intergroup social cognition: an fMRI meta-analysis.

Roughly 20 years of functional magnetic resonance imaging (fMRI) studies have investigated the neural correlates underlying engagement in social cognition (e.g. empathy and emotion perception) about targets spanning various social categories (e.

Beta-adrenergic blockade blunts inflammatory and antiviral/antibody gene expression responses to acute psychosocial stress.

Dysregulation of the immune system is one potential mechanism by which acute stress may contribute to downstream disease etiology and psychopathology. Here, we tested the role of β-adrenergic signaling as a mediator of acute stress-induced changes in immune cell gene expression. In a randomized, double-blind, and placebo-controlled trial, 90 healthy young adults (44% female) received a single 40 mg dose of the β-blocker propranolol (n = 43) or a placebo (n = 47) and then completed the Trier Social Stress Test (TSST).

Affect in the Aging Brain: A Neuroimaging Meta-Analysis of Older Vs. Younger Adult Affective Experience and Perception.

We report the first functional neuroimaging meta-analysis on age-related differences in adult neural activity during affect. We identified and coded experimental contrasts from 27 studies (published 1997-2018) with 490 older adults (55-87 years,  = 69 years) and 470 younger adults (18-39 years,  = 24 years). Using multilevel kernel density analysis, we assessed functional brain activation contrasts for older vs.

Aging bodies, aging emotions: Interoceptive differences in emotion representations and self-reports across adulthood.

Bodily sensations are closely linked to emotional experiences. However, most research assessing the body-emotion link focuses on young adult samples. Inspired by prior work showing age-related declines in autonomic reactivity and interoception, we present 2 studies investigating age-related differences in the extent to which adults (18-75 years) associate interoceptive or internal bodily sensations with emotions.

Feeling hangry? When hunger is conceptualized as emotion.

Many people feel emotional when hungry-or "hangry"-yet little research explores the psychological mechanisms underlying such states. Guided by psychological constructionist and affect misattribution theories, we propose that hunger alone is insufficient for feeling hangry. Rather, we hypothesize that people experience hunger as emotional when they conceptualize their affective state as negative, high arousal emotions specifically in a negative context.

Maternal emotion socialization differentially predicts third-grade children's emotion regulation and lability.

Numerous parental emotion socialization factors have been implicated as direct and indirect contributors to the development of children's emotional competence. To date, however, no study has combined parents' emotion-related beliefs, behaviors, and regulation strategies in one model to assess their cumulative-as well as unique-contributions to children's emotion regulation. We considered the 2 components that have recently been distinguished: emotion regulation and emotional lability.

The role of language in emotion: predictions from psychological constructionism.

Common sense suggests that emotions are physical types that have little to do with the words we use to label them. Yet recent psychological constructionist accounts reveal that language is a fundamental element in emotion that is constitutive of both emotion experiences and perceptions. According to the psychological constructionist Conceptual Act Theory (CAT), an instance of emotion occurs when information from one's body or other people's bodies is made meaningful in light of the present situation using concept knowledge about emotion.

Molecular epidemiology of norovirus gastroenteritis outbreaks in North Carolina, United States: 1995-2000.

Noroviruses (NoVs) are the most common cause of acute non-bacterial gastroenteritis outbreaks in the US. We investigated 16 gastroenteritis outbreaks in North Carolina (NC), from 1995 to 2000, to further characterize the epidemiology of NoV using RT-PCR on stool and ELISA on sera. NoV were identified in 14 outbreaks by RT-PCR.

Human and canine pulmonary blastomycosis, North Carolina, 2001-2002.

We investigated a cluster of blastomycosis in 8 humans and 4 dogs in a rural North Carolina community. Delayed diagnosis, difficulty isolating Blastomyces dermatitidis in nature, and lack of a sensitive and specific test to assess exposure make outbreaks of this disease difficult to study.

Outbreak of listeriosis among Mexican immigrants as a result of consumption of illicitly produced Mexican-style cheese.

Background: In 2000, an outbreak of listeriosis among Hispanic persons was identified in Winston-Salem, North Carolina. The objectives of the present study were to identify the source of, strains associated with, and risk factors for Listeria monocytogenes infection for patients affected by the outbreak.

Methods: Microbiological, case-control, and environmental investigations were conducted.

Economic and social impacts of La Crosse encephalitis in western North Carolina.

La Crosse encephalitis (LACE), a human illness caused by a mosquito-transmitted virus, is endemic in western North Carolina. To assess the economic and social impacts of the illness, 25 serologically confirmed LACE case patients and/or families were interviewed to obtain information on the economic costs and social burden of the disease. The total direct and indirect medical costs associated with LACE over 89.

Histamine poisoning associated with eating tuna burgers.

Context: Histamine poisoning occurs when persons ingest fish in which bacteria have converted histidine to histamine, a process that usually can be controlled by storage at low temperatures. From 1994 to 1997, North Carolina averaged 2 cases annually; however, from July 1998 to February 1999, a total of 22 cases of histamine fish poisoning were reported.

Objectives: To examine the increase in histamine case reports, identify risk factors for poisoning, and develop recommendations for prevention.

Transmission of Norwalk virus during a football game.

Background: During a college football game in Florida, diarrhea and vomiting developed in many of the members of a North Carolina team. The next day, similar symptoms developed in some of the players on the opposing team.

Methods: We interviewed those who ate the five meals served to the North Carolina team before the game and some of the players on the opposing team who became ill.
