#1
Uta-Susan Donges, Thomas Suslow
Alexithymia is a personality trait characterized by difficulties in recognizing and verbalizing emotions and the utilization of a cognitive style that is oriented toward external events, rather than intrapsychic experiences. Alexithymia is considered a vulnerability factor influencing onset and course of many psychiatric disorders. Even though emotions are, in general, elicited involuntarily and emerge without conscious effort, it is surprising that little attention in etiological considerations concerning alexithymia has been given to deficits in automatic emotion processing and their neurobiological bases...

Negative racial stereotypes tend to associate Black people with threat. This often leads to the misidentification of harmless objects as weapons held by a Black individual. Yet, little is known about how bodily states impact the expression of racial stereotyping. By tapping into the phasic activation of arterial baroreceptors, known to be associated with changes in the neural processing of fearful stimuli, we show activation of race-threat stereotypes synchronized with the cardiovascular cycle. Across two established tasks, stimuli depicting Black or White individuals were presented to coincide with either the cardiac systole or diastole...

BACKGROUND: The World Health Organization (WHO) stated in March 2016 that there was scientific consensus that the mosquito-borne Zika virus was a cause of the neurological disorder Guillain-Barré syndrome (GBS) and of microcephaly and other congenital brain abnormalities based on rapid evidence assessments. Decisions about causality require systematic assessment to guide public health actions. The objectives of this study were to update and reassess the evidence for causality through a rapid and systematic review about links between Zika virus infection and (a) congenital brain abnormalities, including microcephaly, in the foetuses and offspring of pregnant women and (b) GBS in any population, and to describe the process and outcomes of an expert assessment of the evidence about causality...

The current study examines the additive and joint roles of chronic poverty-related adversity and three candidate neurocognitive processes of emotion regulation (ER)-including: (i) attention bias to threat (ABT); (ii) accuracy of facial emotion appraisal (FEA); and (iii) negative affect (NA)-for low-income, ethnic minority children's internalizing problems (N = 338). Children were enrolled in the current study from publicly funded preschools, with poverty-related adversity assessed at multiple time points from early to middle childhood...

Psychosocial well-being requires effective regulation of emotional responding in context of threat or stress. Neuroimaging studies have focused on instructed, volitional regulation (e.g., reappraisal or distancing), largely ignoring implicit regulation that does not involve purposeful effort to alter emotional experience. These implicit processes may or may not involve the same neural pathways as explicit regulatory strategies. We examined the neurobiology of implicit emotional regulation processes and the impact of the stress hormone cortisol on these processes...

Previous research demonstrates that sports coaching is a stressful activity. This article investigates coaches' challenge and threat cognitive appraisals of stressful situations and their impact on coaching behaviour, using Blascovich and Mendes' (2000) biopsychosocial model as a theoretical framework. A cross-sectional correlational design was utilised to examine the relationships between irrational beliefs (Shortened general attitude and belief scale), challenge and threat appraisals (Appraisal of life events scale), and coaching behaviours (Leadership scale for sports) of 105 professional football academy coaches...

BACKGROUND: Anxiety and depression occurring during childhood and adolescence are common and costly. While early-emerging anxiety and depression can arise through a complex interplay of 'distal' factors such as genetic and environmental influences, temperamental characteristics and brain circuitry, the more proximal mechanisms that transfer risks on symptoms are poorly delineated. Information-processing biases, which differentiate youth with and without anxiety and/or depression, could act as proximal mechanisms that mediate more distal risks on symptoms...

OBJECTIVE: This prospective study examined the course and potential predictors of parents' posttraumatic stress symptoms (PTSS) after burn injury in their child (Age 8 to 18 years). METHOD: One hundred eleven mothers and 91 fathers, representing 118 children, participated in the study. Within the first month after the burn event and subsequently at 3, 12, and 18 months postburn, both parents completed the Impact of Event Scale (IES). Parental emotions related to the burn event and appraisal of threat to the child's life were assessed, which were investigated in a multilevel regression model...

Theoretical conceptualizations of awe suggest this emotion can be more positive or negative depending on specific appraisal processes. However, the emergent scientific study of awe rarely emphasizes its negative side, classifying it instead as a positive emotion. In the present research we tested whether there is a more negative variant of awe that arises in response to vast, complex stimuli that are threatening (e.g., tornadoes, terrorist attack, wrathful god). We discovered people do experience this type of awe with regularity (Studies 1 & 4) and that it differs from other variants of awe in terms of its underlying appraisals, subjective experience, physiological correlates, and consequences for well-being...

BACKGROUND: Fear conditioning and extinction are prevailing experimental and etiological models for normal and pathological anxiety. Pupil dilations in response to conditioned stimuli are increasingly used as a robust psychophysiological readout of fear learning, but their neural correlates remain unknown. We aimed at identifying the neural correlates of pupil responses to threat and safety cues during a fear learning task. METHODS: Thirty-four healthy subjects underwent a fear conditioning and extinction paradigm with simultaneous functional magnetic resonance imaging (fMRI) and pupillometry...

OBJECTIVE: The aim of this study was to investigate whether cognitive variables proposed by the protection motivation theory (PMT) were predictive of occasional and frequent intention to drive after drinking in medical students. METHODS: One hundred fifty-five students attending preclinical years at a Medical School in São Paulo, Brazil, participated in the study. They were asked about their last month substance use, history of drinking and driving, including driving after binge drinking, and risk perceptions based on a self-report questionnaire with statements about protection motivation, threat, and coping appraisals from the PMT model...

Officials are expected to perform impeccably despite the wide range of stressors they experience. A stressor that officials frequently report is situation criticality. Situation criticality is comprised of score differential (i.e., more pressure in close games) and time remaining in a game (i.e., more pressure as time expires), which affects athletes' stress levels. The present study explored the effect of situation criticality on officials' stress levels. High school basketball officials (n = 108) with an average of 18...

The study investigated threat versus challenge appraisals of acculturative stressors and their impact on the changes in psychological symptoms. It also examined information processing styles (informational, normative, and diffuse-avoidant) as moderators of these relationships. A 6-month longitudinal study with two measuring points was conducted with a sample of immigrants. Threat appraisal was associated with more psychological symptoms, and challenge appraisal interacted with information processing styles to predict the changes in somatic symptoms...

Patients with borderline personality disorder (BPD) suffer greatly from their unstable interpersonal relationships. Studies on explanatory mechanisms driving social dysfunctions in patients' real-life relationships are, however, lacking. Here, we aimed to investigate one of the most central aspects of close relationships, interpersonal trust, in romantic relationships of persons with BPD. We tested the hypothesis that patients with BPD show unstable trustworthiness perception toward their partner, which we expected to be most pronounced after a relationship-threatening situation...

Objective: Traumatic stressors and other forms of adversities, especially when experienced during childhood, shape aggressive behavior. Effects of differential dimensions of impulsivity on the relationship between psychological trauma, reactive aggression (defensive survival response to threat), and appetitive aggression (the pleasure of attacking and fighting) have not yet been assessed. Method: Using structural equation modeling, we sought to uncover precursors of reactive and appetitive aggression investigating a sample of 94 adult individuals with refugee status...

Biased stress appraisals critically relate to the origins and temporal course of many-perhaps most-forms of psychopathology. We hypothesized that aberrant stress appraisals are linked directly to latent internalizing and externalizing traits that, in turn, predispose to multiple disorders. A high-risk community sample of 815 adolescents underwent semistructured interviews to assess clinical disorders and naturalistic stressors at ages 15 and 20. Participants and blind rating teams separately evaluated the threat associated with acute stressors occurring in the past year, and an appraisal bias index (i...

There is a growing recognition that parental socialization influences interact with young children's emerging capacity for physiological regulation and shape children's developmental trajectories. Nevertheless, the transactional processes linking parental socialization and physiological regulatory processes remain not well understood, particularly for fear-prone toddlers. To address this gap in the literature, the present study investigated the biopsychosocial processes that underlie toddlers' fear regulation by examining the relations among toddler parasympathetic regulation, maternal appraisal, and parenting behaviors...

BACKGROUND: Fear appeals are persuasive messages that draw attention to the negative consequences (e.g., academic failure) that follow a particular course of action (e.g., not engaging in lessons) and how negative consequences can be avoided with an alternate course of action. Previous studies have shown that when fear appeals are appraised as threatening, they are related to lower examination performance. AIM: In this study, we examined how challenge, as well as threat, appraisals are indirectly related to performance on a mathematics examination through behavioural engagement...

BACKGROUND: Despite considerable effort, the neurobiological underpinnings of hyper-responsive threat processing specific to patients suffering from generalized anxiety disorder (GAD) remain poorly understood. The current functional magnetic resonance imaging (fMRI) study aims to delineate GAD-specific brain activity during immediate threat processing by comparing GAD patients to healthy controls (HC), to social anxiety disorder (SAD) and to panic disorder (PD) patients. METHOD: Brain activation and functional connectivity patterns to threat vs...
