ABSTRACT

Studies have shown a significant association between effective parasympathetic modulation of the heart and processes linked to social cognition. Particularly, Quintana and colleagues documented a relation between vagally-mediated heart rate variability (vmHRV) and performance on a theory of mind (ToM) task, namely, the Reading the Mind in the Eyes Test (RMET), in a sample of university students. The purpose of the present study was to test whether such result would extend to a sample of school-aged children (7-9 years old) using the child version of the RMET. In addition, the Eyes Test Revised was administered as it is more suitable to evaluate ToM during childhood. Results supported the positive association between vmHRV and ToM abilities, replicating and extending previous results obtained in young adults. The current study adds to the existing literature pointing to HRV as a putative biomarker of social cognition abilities.

ABSTRACT

OBJECTIVE: This ecological study explored the association between regulatory emotional self-efficacy beliefs in managing negative emotions (RESE-NE) and heart rate variability (HRV), a measure of parasympathetic modulation of the heart that has been positively associated with a better ability to flexibly adjust to a changing environment and regulate emotions. METHOD: To test these associations, we used data from 161 adults working in relational professions (about 40% men; mean [standard deviation] age = 40.45 [14.17] years) whose HRV was assessed continuously for 24 hours. RESULTS: Individuals high in RESE-NE showed increased HRV levels ( ß = -0.05, p = .011). However, this effect was moderated by biological sex ( ß = -0.18, p = .0001) such that RESE-NE positively and significantly predicted HRV for men ( ß = 0.18, p < .0001) but not for women ( ß = -0.001, p = .989). CONCLUSIONS: All in all, our study provides initial empirical support for the theoretical expectation derived from social cognitive theory that RESE-NE is positively correlated with a physiological indicator of adaptability to the environmental demands. This was true only for men, likely because of sex differences in physiological stress reactivity and regulation.

ABSTRACT

BACKGROUND: According to the perseverative cognition (PC) hypothesis, the repetitive chronic activation of the cognitive representations of stressors are associated with a concomitant prolonged and sustained physiological stress response, including sleep disruption. PURPOSE: We conducted a systematic review and structural equation modeling meta-analysis (meta-SEM) on PC as mediator of the association between perceived stress and subjective sleep disturbance (i.e., difficulties falling asleep or maintaining sleep). METHODS: PubMed, Scopus, Medline, CINAHL, and PsycInfo were searched up to September 2021. To test mediation, only longitudinal studies assessing the predictor (perceived stress) at T0, the mediator (PC) at T1, and the outcome (sleep disturbance) at T2, were eligible. RESULTS: Findings on 3,733 individuals (k = 8) showed a significant component effect of perceived stress on PC (ß = 0.340, p < .001), which in turn was related to sleep disturbance (ß = 0.258, p < .001). The direct effect of stress on sleep disturbance was significant (ß = 0.133, p < .001). Lastly, the indirect effect between stress and sleep disturbance via PC supported the mediation hypothesis (ß = 0.09, 95% CI 0.078-0.100). The mediation path remained significant (ß = 0.03, 95% CI 0.020-0.036) after adjusting for baseline sleep disturbance. Further leave-one-out sensitivity and control analyses confirmed that all direct and indirect effects were not driven by any single study included in the meta-analysis, as well as their robustness when controlling for sex and age, respectively. CONCLUSIONS: Overall, results of this meta-analysis indicate that PC may be one of the mechanisms explaining how perceived stressful experiences lead to subjective sleep disturbance.


The repetitive chronic activation of the cognitive representations of stressors, known as perseverative cognition (PC), is associated with a concomitant prolonged and sustained physiological stress response, with may include sleep disturbance. This study investigates the mediating role of PC in the association between perceived stress and subjective indices of sleep disturbance using structural equation modeling meta-analysis (meta-SEM). PubMed, Scopus, Medline, CINAHL, and PsycInfo were searched up to September 2021. Findings on eight studies (n = 3,733 individuals) showed a significant component effect of perceived stress on PC, which in turn was related to sleep disturbance. The direct effect of stress on sleep disturbance was significant. Finally, the indirect effect between stress and sleep disturbance via PC supported the mediation hypothesis. Results of this meta-analysis suggest that PC may be one of the mechanisms explaining how perceived stressful experiences lead to subjective sleep disturbance.

ABSTRACT

Pavlovian conditioning holds the potential to incentivize environmental cues, leading to approach behavior toward them, even outside our awareness. Animal models suggest that this is particularly true for the so-called sign-tracker (ST) phenotype, which is considered to reflect a predisposition toward developing addiction-related behaviours. Despite its potential clinical relevance, few studies have demonstrated the translational validity of this model, likely due to difficulties in studying Pavlovian processes in humans. To fill this gap, we combined an ecological momentary assessment with ambulatory peripheral autonomic monitoring to test the hypothesis that traits associated with ST in preclinical studies would be associated with attribution of high incentive salience to reward-related cues. Several times for 2 days, participants were asked to rate the attractiveness of several preselected ecological rewards (e.g., coffee) and the preceding cues (the smell of coffee) while their electrocardiogram was recorded. While no absolute difference in subjective and physiological measures of motivational approach to daily cues compared with rewards emerged, individuals with high levels of impulsivity, obsessive-compulsive, and addiction-prone behaviors rated as more attractive and showed a greater increase in sympathetic arousal to cues versus rewards. The opposite pattern emerged for those with low levels in those dispositional traits, who responded more (both subjectively and physiologically) to rewards compared with their preceding cues. This study represents an attempt to answer the call to parcel complex behaviors into smaller constructs, improving the early detection of those who are vulnerable to develop psychopathological disorders, particularly in the domain of impulse control such as addiction.

ABSTRACT

Resting heart rate variability (HRV), a surrogate index of cardiac vagal modulation, is considered a putative biomarker of stress resilience as it reflects the ability to effectively regulate emotions in a changing environment. However, most studies are cross-sectional, precluding longitudinal inferences. The high degree of uncertainty and fear at a global level that characterizes the COVID-19 pandemic offers a unique opportunity to explore the utility of HRV measures as longitudinal predictors of stress resilience. This study examined whether resting measures of HRV prior to the COVID-19 outbreak (i.e. nearly 2 years before; Time 0) could predict emotion regulation strategies and daily affect in healthy adults during the May 2020 lockdown (Time 1). Moreover, we evaluated the association between HRV measures, emotion regulation strategies, subjective perception of COVID-19 risk, and self-reported depressive symptoms at Time 1. Higher resting HRV at Time 0 predicted a stronger engagement in more functional emotion regulation strategies, as well as of higher daily feelings of safeness and reduced daily worry at Time 1. Moreover, depressive symptoms negatively correlated with HRV and positively correlated with the subjective perception of COVID-19 risk at Time 1. Current data support the view that HRV might not only be a marker but also a precursor of resilience under stressful times.

ABSTRACT

BACKGROUND: Anxiety related to the dental context is a clinically significant challenge. In children, dental fear is often accompanied by disruptive and uncooperative behaviours that can render treatment difficult. Although techniques to reduce children's anxiety exist, many have not been formally evaluated. DESIGN: Diaphragmatic breathing has been shown to reduce fear and anxiety, but few investigations have evaluated whether it can reduce dental anxiety in children. This crossover study tested the effectiveness and feasibility of diaphragmatic breathing in twenty children undergoing dental care. RESULTS: Compared with the treatment as usual, such a simple technique had significant benefits on mood, self-reported pain and autonomic balance, thus reducing sympathetic activation. CONCLUSION: Diaphragmatic breathing is a low-cost, easy-to-implement technique suitable for daily dental practice, and is a promising tool for reducing negative effect and physiological distress in children with dental anxiety that results in more cooperative behaviours and reduced visit time.

ABSTRACT

This study examines the change and associations in parental emotion socialization strategies in response to children's negative emotions and youths' adjustment, comparing before the Covid-19 pandemic hit Italy and since the pandemic began. Participants were convenient cross-sectional/normative (Study 1) and clinical/longitudinal (Study 2) samples of Italian parents whose children were in middle childhood and adolescence. In Study 1, self-reported socialization strategies, youths' maladjustment, and emotion dysregulation increased since the pandemic began. Whereas, in Study 2, socialization strategies and youths' maladjustment decreased since the pandemic started. In both studies, unsupportive parental emotion socialization predicted youths' maladjustment and emotion dysregulation, while supportive parental emotion socialization predicted adaptive emotion regulation. This study advances knowledge about the impact of the Covid-19 pandemic on the family context.

ABSTRACT

Affect plays a major role in the individual's daily life, driving the sensemaking of experience, psychopathological conditions, social representations of phenomena, and ways of coping with others. The characteristics of affect have been traditionally investigated through physiological, self-report, and behavioral measures. The present article proposes a text-based measure to detect affect intensity: the Affective Saturation Index (ASI). The ASI rationale and the conceptualization of affect are overviewed, and an initial validation study on the ASI's convergent and concurrent validity is presented. Forty individuals completed a non-clinical semi-structured interview. For each interview transcript, the ASI was esteemed and compared to the individual's physiological index of propensity to affective arousal (measured by heart rate variability (HRV)); transcript semantic complexity (measured through the Semantic Entropy Index (SEI)); and lexical syntactic complexity (measured through the Flesch-Vacca Index (FVI)). ANOVAs and bi-variate correlations estimated the size of the relationships between indexes and sample characteristics (age, gender), then a set of multiple linear regressions tested the ASI's association with HRV, the SEI, and the FVI. Results support the ASI construct and criteria validity. The ASI proved able to detect affective saturation in interview transcripts (SEI and FVI, adjusted R2 = 0.428 and adjusted R2 = 0.241, respectively) and the way the text's affective saturation reflected the intensity of the individual's affective state (HRV, adjusted R2 = 0.428). In conclusion, although the specificity of the sample (psychology students) limits the findings' generalizability, the ASI provides the chance to use written texts to measure affect in accordance with a dynamic approach, independent of the spatio-temporal setting in which they were produced. In doing so, the ASI provides a way to empower the empirical analysis of fields such as psychotherapy and social group dynamics.

ABSTRACT

Prolonged or repeated activation of the stress response can have negative psychological and physical consequences. The prefrontal cortex (PFC) is thought to exert an inhibitory influence on the activity of autonomic and neuroendocrine stress response systems. In this study, we further investigated this hypothesis by increasing PFC excitability using transcranial direct current stimulation (tDCS). Healthy male participants were randomized to receive either anodal (excitatory) tDCS (n = 15) or sham stimulation (n = 15) over the left dorsolateral prefrontal cortex (DLPFC) immediately before and during the exposure to a psychosocial stress test. Autonomic (heart rate (HR) and its variability) and neuroendocrine (salivary cortisol) parameters were assessed. One single session of excitatory tDCS over the left DLPFC (i) reduced HR and favored a larger vagal prevalence prior to stress exposure, (ii) moderated stress-induced HR acceleration and sympathetic activation/vagal withdrawal, but (iii) had no effect on stress-induced cortisol release. However, anodal tDCS over the left DLPFC prevented stress-induced changes in the cortisol awakening response. Finally, participants receiving excitatory tDCS reported a reduction in their levels of state anxiety upon completion of the psychosocial stress test. In conclusion, this study provides first insights into the efficacy of one single session of excitatory tDCS over the left DLPFC in attenuating autonomic and neuroendocrine effects of psychosocial stress exposure. These findings might be indicative of the important role of the left DLPFC, which is a cortical target for noninvasive brain stimulation treatment of depression, for successful coping with stressful stimuli.

ABSTRACT

Internal Working Models of the attachment system modulate emotional responses and the Disorganized attachment pattern is characterized by the breakdown of such regulation. Vagally-mediated heart rate variability (vmHRV) is an index of flexible emotional responding. This study investigated vmHRV in non-clinical adults with an Organized or Disorganized attachment pattern before, during, and after the recall of attachment memories via the Adult Attachment Interview (AAI). Whereas the Organized group exhibited a typical decrease in vmHRV during the AAI and asubsequent return to a baseline-like pattern, the Disorganized group unexpectedly showed a sustained increase in vmHRV during the AAI which also persisted during the recovery phase. Results suggest that while Organized face the recollection of attachment memories by showing the adaptive stress response characterized by parasympathetic withdrawal and immediate recovery, individuals with Disorganized attachment need to keep regulating their emotions effortfully both during and after the recall of potential traumatic events.

ABSTRACT

In Generalized Anxiety Disorder (GAD), fluctuations in ongoing thoughts (i.e., mind-wandering) often take the form of rigid and intrusive perseverative cognition, such as worry. Here, we sought to characterise the neural correlates of mind-wandering and perseverative cognition, alongside autonomic nervous system indices of central arousal, notably pupil dilation. We implemented a protocol incorporating the dynamic delivery of thought-probes within a functional neuroimaging task. Sixteen individuals with GAD and sixteen matched healthy controls (HC) underwent functional magnetic resonance imaging with concomitant pupillometry. Participants performed a series of low-demand tracking tasks, responding to occasional changes in a target stimulus. Such a task is typically accompanied by self-generated, off-task thinking. Thought-probes were triggered based on an individual's response time (RT) when responding to the change in the target. Subjective reports showed that long RT predicted off-task thinking/mind-wandering. Moreover, long RT and mind-wandering were also associated with larger pupil diameter. This effect was exaggerated in GAD patients during perseverative cognition. Within brain, during both pre-target periods and target events, there were distinct neural correlates for mind-wandering (e.g., anterior cingulate and paracingulate activation at target onset) and perseverative cognition (e.g., opposite patterns of activation in posterior cingulate and cerebellum at target onset in HC and GAD). Results suggest that not only attention systems but also sensory-motor cortices are important during off-task states. Interestingly, changes across the 'default mode network' also tracked fluctuations in pupillary size. Autonomic expression in pupillary changes mirrors brain activation patterns that occur during different forms of repetitive thinking.

ABSTRACT

Thalamo-cortical connectivity was characterised in a patient with bilateral infarct of the thalami, without evidence of cognitive deficits in everyday life. Patient underwent social and emotional tests, Iowa Gambling Task (IGT), with and without concomitant heart rate variability (HRV) recording and at 3T-MRI to assess thalamo-cortical connectivity. Patient showed impairment at the IGT, in somatic marker, in emotions and theory of mind. MRI documented a bilateral damage of the centromedian-parafascicular complex. Patient's thalamic lesions disconnected brain areas involved in decision-making and autonomic regulation, affecting the somatic marker and resulting in the neuropsychological deficit exhibited by L.C.

ABSTRACT

Several studies have highlighted the role of heart rate variability (HRV) in social engagement and social cognition. However, whether HRV is involved in the ability to remember faces associated with affectively salient behavioural information remains unexplored. The present study aims to close this gap by investigating long-term face-memory accuracy in individuals differing in resting vagally-mediated HRV. Individuals with high or low resting HRV viewed faces associated with episodic information differing in affective valence (positive, neutral, negative) or without any behavioural description. After one week, a face recognition test was administered. High HRV individuals were better at recognizing faces paired with positive and negative behavioural descriptions compared to neutral faces or faces without descriptions. Conversely, low HRV participants did not show any face memory advantage from personal information. The present results suggest that HRV may provide a novel biological marker of long-term face recognition.

ABSTRACT

Objective/Background: According to the Cognitive Model of Insomnia disorder, rumination about lack of sleep and its diurnal consequences plays a crucial role in maintaining insomnia. Consolidated evidence shows that rumination is related to poor executive functions, which are cognitive control processes impacted by insomnia. Despite this evidence, no studies so far investigated the relationship between executive functions and rumination in individuals with insomnia. The aim of this pilot study was to cover this gap by investigating whether poor executive functions are associated with rumination in a sample of individuals with a diagnosis of insomnia disorder. Participants: Thirty young adults (22.67 ± 3.68 years, 73.3% females) diagnosed with insomnia disorder by clinical psychologists with expertise in behavioral sleep medicine completed the study. Methods: Measures of insomnia, depression, emotion regulation, and rumination about the daytime consequences of insomnia were collected. Executive functions were assessed using a Task Switching paradigm, measuring cognitive inhibition and set-shifting with cognitive flexibility. Results: Hierarchical multiple regression analysis revealed that higher depression (ß = 0.781, p < 0.001) and cognitive reappraisal (ß = 0.329, p = 0.016), and poorer cognitive inhibition (ß = -0.334, p = 0.014), significantly predicted higher rumination. Conclusions: Rumination about symptoms of insomnia in a clinical sample is associated with impaired inhibitory but not switching capacities above and beyond the role played by traditional predictors such as depression and emotion regulation strategies. If replicated, present preliminary results suggest the need to target cognitive inhibition deficits in insomnia treatment.

ABSTRACT

OBJECTIVE: High blood pressure (BP) is associated with reduced pain sensitivity, known as BP-related hypoalgesia. The underlying neural mechanisms remain uncertain, yet arterial baroreceptor signaling, occurring at cardiac systole, is implicated. We examined normotensives using functional neuroimaging and pain stimulation during distinct phases of the cardiac cycle to test the hypothesized neural mediation of baroreceptor-induced attenuation of pain. METHODS: Eighteen participants (10 women; 32.7 (6.5) years) underwent BP monitoring for 1 week at home, and individual pain thresholds were determined in the laboratory. Subsequently, participants were administered unpredictable painful and nonpainful electrocutaneous shocks (stimulus type), timed to occur either at systole or at diastole (cardiac phase) in an event-related design. After each trial, participants evaluated their subjective experience. RESULTS: Subjective pain was lower for painful stimuli administered at systole compared with diastole, F(1, 2283) = 4.82, p = 0.03. Individuals with higher baseline BP demonstrated overall lower pain perception, F(1, 2164) = 10.47, p < .0001. Within the brain, painful stimulation activated somatosensory areas, prefrontal cortex, cingulate cortex, posterior insula, amygdala, and the thalamus. Stimuli delivered during systole (concurrent with baroreceptor discharge) activated areas associated with heightened parasympathetic drive. No stimulus type by cardiac phase interaction emerged except for a small cluster located in the right parietal cortex. CONCLUSIONS: We confirm the negative associations between BP and pain, highlighting the antinociceptive impact of baroreceptor discharge. Neural substrates associated with baroreceptor/BP-related hypoalgesia include superior parietal lobule, precentral, and lingual gyrus, regions typically involved in the cognitive aspects of pain experience.

ABSTRACT

Human cognition is not limited to the available environmental input but can consider realities that are different to the here and now. We describe the cognitive states and neural processes linked to the refinement of descriptions of personal goals. When personal goals became concrete, participants reported greater thoughts about the self and the future during mind-wandering. This pattern was not observed for descriptions of TV programmes. Connectivity analysis of participants who underwent a resting-state functional magnetic resonance imaging scan revealed neural traits associated with this pattern. Strong hippocampal connectivity with ventromedial pre-frontal cortex was common to better-specified descriptions of goals and TV programmes, while connectivity between hippocampus and the pre-supplementary motor area was associated with individuals whose goals were initially abstract but became more concrete over the course of the experiment. We conclude that self-generated cognition that arises during the mind-wandering state can allow goals to be refined, and this depends on neural systems anchored in the hippocampus.

ABSTRACT

BACKGROUND: The ability of the human brain to escape the here and now (mind wandering) can take functional (problem solving) and dysfunctional (perseverative cognition) routes. Although it has been proposed that only the latter may act as a mediator of the relationship between stress and cardiovascular disease, both functional and dysfunctional forms of repetitive thinking have been associated with blood pressure (BP) reactivity of the same magnitude. However, a similar BP reactivity may be caused by different physiological determinants, which may differ in their risk for cardiovascular pathology. PURPOSE: To examine the way (hemodynamic profile) and the extent (compensation deficit) to which total peripheral resistance and cardiac output compensate for each other in determining BP reactivity during functional and dysfunctional types of repetitive thinking. METHODS: Fifty-six healthy participants randomly underwent a perseverative cognition, a mind wandering, and a problem solving induction, each followed by a 5-min recovery period while their cardiovascular parameters were continuously monitored. RESULTS: Perseverative cognition and problem solving (but not mind wandering) elicited BP increases of similar magnitude. However, perseverative cognition was characterized by a more vascular (versus myocardial) profile compared to mind wandering and problem solving. As a consequence, BP recovery was impaired after perseverative cognition compared to the other two conditions. CONCLUSIONS: Given that high vascular resistance and delayed recovery are the hallmarks of hypertension the results suggest a potential mechanism through which perseverative cognition may act as a mediator in the relationship between stress and risk for developing precursors to cardiovascular disease.

ABSTRACT

BACKGROUND: The high incidence and prevalence rates of depression among students identify them as a vulnerable population and make the case for the development of cost-effective treatments. AIMS: We aimed to examine the comparative effects of brief group metacognitive therapy (MCT) versus behavioural activation (BA) treatments for depression, anxiety, and emotion regulation in university students. METHOD: All participants (25 women, 16 men; age range: 18-30 years) fulfilled criteria for major depression and were randomly assigned to MCT (n = 15), BA (n = 15), or a wait-list control group (n = 15). The treatment groups received 8 weekly MCT or BA sessions. Scores on the Beck Depression Inventory, Beck Anxiety Inventory, and Cognitive Emotion Regulation Questionnaire were used as outcome measures. RESULTS: This pilot study showed that both treatments were equally effective for depressive and anxiety symptoms. However, therapeutic techniques differed with regards to their effects on specific facets of emotion regulation, such as Positive Reappraisal and Catastrophizing, with MCT being more effective compared to BA. BA also showed a stronger relapse at follow-up with regards to Acceptance and Refocus on Planning. CONCLUSIONS: Results suggest that groups MCT and BA may be implemented as cost-effective treatments for students with moderate depression.

ABSTRACT

Early maladaptive schemas (EMSs) are cognitive patterns resulting from unmet core emotional needs in childhood that have been linked to the development of psychopathology. As depression is a multifaceted phenomenon, we hypothesized that specific dysphoric symptoms would be predicted by different EMSs. Four hundred and fifty-six participants completed a measure of EMSs (Young Schema Questionnaire) and reported on the severity of the symptoms of criterion A for major depression in DSM-IV during the occurrence of a dysphoric episode in the previous 12 months. A series of stepwise multiple regression analyses were performed to investigate the predictive power of the EMSs for the severity of each specific depressive symptom. When controlling for gender and current levels of depression, specific symptoms were predicted by different EMSs: sadness by Negativity/Pessimism; anhedonia by Failure; self-harm by Emotional Deprivation and Vulnerability to Harm or Illness; worthlessness by Failure and Negativity/Pessimism; psychomotor retardation/restlessness by Vulnerability to Harm or Illness and Entitlement/Grandiosity; and poor concentration by Insufficient Self-Control/Self-Discipline. The more physical symptoms of fatigue, insomnia/hypersomnia, and appetite loss/appetite gain were not predicted by any of the EMSs. Although the cross-sectional design of the study does not allow for conclusions about the direction of effects, results suggest that depression is not a unitary phenomenon and provide a possible explanation for previous inconsistent findings.

ABSTRACT

BACKGROUND: The construct of self-compassion is receiving increased attention due to its strong link to mental health. Nonetheless, many questions concerning its dimensionality and construct validity remain open. AIMS: The purpose of this study was to evaluate the factorial structure and construct validity of the Self-Compassion Scale (SCS) in a sample of 424 Italian participants ranging in age from 17 to 65 years. METHOD: SCS was translated with a back-translation procedure and then administered through an on-line survey, along with measures of self-blame, subjective loneliness, emotion regulation, depression and anxiety. RESULTS: Confirmatory factor analysis (CFA) confirmed the six-factor model both in the overall sample and in gender and age subgroups. CFA did not support the single higher-order factor of self-compassion, originally found by the author of the scale. Negative associations of Self-Kindness, Common Humanity and Mindfulness subscales with anxiety and depression were confirmed. Moreover, negative correlations of these subscales with self-blame, positive correlations with reappraisal and non-significant associations with expressive suppression and subjective loneliness were found, unveiling aspects of the construct not fully investigated in empirical research. CONCLUSIONS: Findings suggest that the SCS is a reliable tool but its dimensionality may vary according to different cultural contexts.
