Children with attention deficit/hyperactivity disorder (ADHD) display alterations in both emotion reactivity and regulation. One mechanism underlying such alternations may be reduced coherence among emotion systems (i.e., autonomic, facial affect). The present study sought to examine this. One hundred children (50 with ADHD combined presentation), 7-11 years of age (62% male, 78% White), completed an emotion induction and suppression task. This task was coded for facial affect behavior across both negative and positive emotion eliciting task conditions...

BACKGROUND: Amygdala hyper-reactivity is sometimes assumed to be a vulnerability factor that predates depression; however, in healthy people, who experience early life stress but do not become depressed, it may represent a resilience mechanism. We aimed to test these hypothesis examining whether increased amygdala activity in association with a history of early life stress (ELS) was negatively or positively associated with depressive symptoms and impact of negative life event stress in never-depressed adults...

The autonomic nervous system (ANS) plays an important role in attention and self-regulation by modulating physiological arousal to meet environmental demands. Core symptoms of ADHD such as inattention and behavioral disinhibition may be related to dysregulation of the ANS, however previous findings have been equivocal. We examined autonomic activity and reactivity by assessing heart rate variability (HRV) in a large sample of un-medicated children and adolescents (6-19 years) with ADHD (n=229) compared to typically-developing controls (n=244) during rest and sustained attention...

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...

Reports an error in "Self-critical perfectionism and depressive and anxious symptoms over 4 years: The mediating role of daily stress reactivity" by Tobey Mandel, David M. Dunkley and Molly Moroz (Journal of Counseling Psychology, 2015[Oct], Vol 62[4], 703-717). (The following abstract of the original article appeared in record 2015-32534-001.) This study of 150 community adults examined heightened emotional reactivity to daily stress as a mediator in the relationships between self-critical (SC) perfectionism and depressive and anxious symptoms over a period of 4 years...

The investigation of callous-unemotional (CU) traits has been central to contemporary research on child behavior problems, and served as the impetus for inclusion of a specifier for conduct disorder in the latest edition of the official psychiatric diagnostic system. Here, we report results from 2 studies that evaluated the construct validity of callousness as assessed in adults, by testing for affiliated deficits in behavioral and neural processing of fearful faces, as have been shown in youthful samples. We hypothesized that scores on an established measure of callousness would predict reduced recognition accuracy and diminished electocortical reactivity for fearful faces in adult participants...

PTSD is characterized by both affective and cognitive dysfunction. Affectively, PTSD is associated with both heightened emotional reactivity and disengagement. Cognitively, perseverative thinking is a core feature of the disorder. In order to assess the interactive effects of affective and cognitive correlates of PTSD symptoms, 47 OEF/OIF/OND veterans completed an emotional faces matching task while EEG (i.e., late positive potential; LPP) was recorded, and separately completed the Wisconsin Card Sorting Test (WCST) to assess perseverative errors...

BACKGROUND: Emotional stress is associated with increased risk of cardiovascular disease. We imaged the amygdala, a brain region involved in stress, to determine whether its resting metabolic activity predicts risk of subsequent cardiovascular events. METHODS: Individuals aged 30 years or older without known cardiovascular disease or active cancer disorders, who underwent (18)F-fluorodexoyglucose PET/CT at Massachusetts General Hospital (Boston, MA, USA) between Jan 1, 2005, and Dec 31, 2008, were studied longitudinally...

Alterations in the Duchenne muscular dystrophy (DMD) gene have been associated with enhanced stress reactivity in vertebrate species, suggesting a role for brain dystrophin in fear-related behavioral and cognitive processes. Because the loss of dystrophin (Dp427) reduces clustering of central GABAA receptors, it is suspected that local inhibitory tuning and modulation of neuronal excitability are perturbed in a distributed brain circuit that normally controls such critical behavioral functions. In this study we undertook a large-scale behavioral study to evaluate fear-related behavioral disturbances in dystrophin-deficient mdx mice...

Why do people expose themselves to certain emotional stimuli and avoid others? We propose that what people want to feel is linked to attitudes toward emotions. In 3 studies, we show that individuals with more (vs. less) negative attitudes toward an emotion were more (vs. less) likely to avoid stimuli that induce that emotion. People who evaluated disgust (or joy) less favorably than others were less likely to expose themselves to disgusting (or joyful) pictures (Study 1). These links were emotion-specific and could not be explained by differences in state or trait emotion (Study 2) or in emotional reactivity (Study 3)...

Social perception of emotions is influenced by the context in which it occurs. One such context is a social interaction involving an exchange of emotions. The way parties to the interaction are perceived is shaped by the combination of emotions exchanged. This idea was examined by assessing the extent to which expressions of anger toward a target-which, in isolation, are perceived as signals of high social power-are influenced by the target's emotional reaction to it (i.e., reactive emotions). Three studies show that the angry person was perceived as having a higher level of social power when this anger was responded by fear or sadness than when it was responded by neutrality or anger...

Throughout a marriage couples will share countless ordinary moments together that may seem trivial, but which actually have potential to affirm and strengthen relational bonds. According to theories of emotional capital, the accumulation of shared positive moments in a relationship should serve as an essential resource for protecting the relationship against threats. To date, however, few empirical studies have explored the role emotional capital may play in shaping responses to negative relationship experiences...

BACKGROUND AND OBJECTIVES: Repressors tend to report less negative emotion and to describe challenges as less stressful, yet tend to exhibit higher rates of cardiovascular disease. While repressive coping has been shown to be associated with exaggerated physiological reactivity to novel stress, we sought to establish if elevated responses persisted across repeated exposure. DESIGN AND METHODS: In a sample of 86 healthy female adults, a verbal-autonomic response dissociation index of repressive coping was computed...

The reactive traits of Sensitivity to Punishment (SP) and Sensitivity to Reward (SR) are assumed to be involved in the development of Eating Disorders (EDs). Most studies examine whether levels of these traits differ between ED diagnoses, without taking other variables into account. However, vulnerability theories of psychopathology posit that the risk for psychopathology depends on the interaction between reactive traits and self-regulatory traits such as Effortful Control (EC). As such, the present objective was to examine the moderating role of EC in the association between SP, SR and the eating styles restrained eating, emotional eating and external eating as possible ED precursors in adolescents...

OBJECTIVE/BACKGROUND: Poor sleep quality is common in pregnancy and associated with increased psychological distress, which has adverse consequences for families. Emerging theory suggests that mindfulness-based interventions may help reduce cognitive and emotional reactivity to stressful events. The current study examines the effects of a mindfulness-based intervention on the relationship between poor sleep quality and increased depression symptom severity and perceived stress during pregnancy...

Motivational models of psychopathology have long been advanced by psychophysiologists, and have provided key insights into neurobiological mechanisms of a wide range of psychiatric disorders. These accounts emphasize individual differences in activity and reactivity of bottom-up, subcortical neural systems of approach and avoidance in affecting behavior. Largely independent literatures emphasize the roles of top-down, cortical deficits in emotion regulation and executive function in conferring vulnerability to psychopathology...

OBJECTIVE: Knee Osteoarthritis (OA) is a chronic disease caused by the deterioration of cartilage in joints, which results in activation of the inflammatory response, pain, and impaired movement. Complementary therapies, particularly supplementation, in the management of moderate/severe knee OA have been gaining attention. This registry study aimed at evaluating the synergistic effect of Movardol®, a supplementation containing active ingredients with recognized anti-inflammatory activities on symptoms and levels of circulating biomarkers of knee OA...

Most people are exposed to at least one traumatic event during the course of their lives, but large numbers of people do not develop posttraumatic stress disorders. Although previous studies have shown that repeated and chronic stress change the brain's structure and function, few studies have focused on the long-term effects of acute stressful exposure in a nonclinical sample, especially the morphology and functional connectivity changes in brain regions implicated in emotional reactivity and emotion regulation...

Co-regulation of behavior occurring within parent-child attachment relationships is thought to be the primary means through which children develop the capacity to regulate emotion, an ability that is protective across development. Existing research on parent-child co-regulation focuses predominantly on parent-infant dyads, and operationalizes co-regulation as the matching of facial expressions; however, matching can occur on other behaviors, including vocal tone, body movement, and language. Studies with young children find that greater matching is associated with children's lower emotion reactivity, but with unknown impacts on parents...

OBJECTIVE: Though family-of-origin aggression (FOA) is a known risk for later emotional and physical problems in adulthood, little is known about how early exposure to aggression influences physiological reactivity in the domain-specific context of family conflict experienced as an adult. This study investigates whether report of FOA influences spouses' hypothalamic-pituitary-adrenal (HPA) axis responses during conflict discussions with their family-of-procreation and also whether current hostilities, observed during a family discussion, moderate those responses...
